- + Отличное активное шумоподавление
Удобно сидят, нигде не давят
Хорошее качество звука - - В наушниках начинает болтаться динамик и, как следствие, ломаются внутренние провода
- + Шумоподавление фантастическое! Достаточно удобно сидят, но qc15 на мой вкус сидели еще лучше. Крепкий провод на стандартном (джек 2,5 4 контакта) разъеме в левом ухе, "алюминиевый" дизайн, дорогая стильная конструкция, жесткий довольно компактный чехол. Работают и без батарейки - большое достоинство, как оказалось! Звук на высоте
- - Шумоподавление требует привычки. Первый раз включение этой системы вызывает у многих головокружение, головную боль, даже тошноту. особенно в не очень шумном месте. Чехол жесткий, но достать из него на ходу наушники, раскрыть их очень не удобно. Плохо переносят ветер, очень плохо переносят даже быструю ходьбу, не говоря о беге. Выработал плавную походку). Появился временами какой-то посторонний...
- + Очень хорошо давят звук. Звук по качеству немного лучше, чем стандартные уши от iPhone 5 или дешевые затычки от Sennheiser
- - Действительно ощущается некоторое давление на перепонки, но к этому быстро привыкаешь. Через несколько часов начинают потеть уши, но это характерно для всех закрытых наушников.
- + 1. Шумоподавление
2. Практичность
3. Дизайн
4. Звук
5. Возможности - - Пока не выявил
Итак, звук стал однозначно лучше. На мой взгляд, наблюдается улучшение по всем частотам.
Чехол стал куда лучше. Теперь там есть специальный отсек для батарейки, а сам чехол стал практичнее.
Наушники теперь складываются, вот уж чего не хватало.
Работают без включенного шумдава, впрочем, мало толку в этом, ибо звук ужасен, режим исключительно...
- + Наушники для командировок, шумных мест и т.п.
Классный шумодав, батарейка работает долго. - - внешняя часть корпуса - алюминий, легко повредить, погнуть. носил...
- + Нормальный звук, хорошо давит шум, удобные, качественно сделаные, уши полностью внутри и ничего не натирает, офигенный жесткий чехол
- - Завышенная цена, если выключен шумодав звук становится унылым, кнопки на проводочке странно работают с андроидом (работает пауза/воспроизведение и то как то через раз, остальные кнопки не работают), далее провод имеет 3 контакта и не захотел дружить со стандартным стерео входом в звуковухе на компе (звук идет обрезанный по некоторым дорожкам), если включать шумодав без музыки то ощущается эффект давления на уши, очень похоже на то когда взлетаешь на самолете / едешь на скоростном лифте...
- + Шумоподавление, качество исполнения, дизайн, комплектация, разбираемая конструкция.
- - Качество звука (в сравнении с sennheiser 280 pro) - описано ниже, цена (брал за 13100), при энергичной ходьбе странно "прыгают"...
- + Качество звука, хорошо сидят на голове, работают как с Apple так и с Windows / Android, удобно спать в них, посивное / активное шумоподовление
- - За 4 года активного использования стёрлись и порвались амбушюры, сложно найти оригинальные амбушюры, при активном шумоподовлении при нажатии на наушники, последние производят сильную волну ультразвука
когда я готов купить эти наушники, совместимые модели планшетов не было в наличии, поэтому я решила купить совместимые версии Apple. Кнопку посещают звонок будет работать для обеих Apple и Android телефонов, но объем вверх,вниз ключ не будет работать на телефоне Android, который является для меня не проблема. Андроид модель стоит дороже, чем Apple версию, а на Андроид совместимый кабель доступны на AliExpress всего за$2.
а теперь приходят на "точку титул". QC35 имеет Bluetooth преимуществом, но намного дороже по сравнению с QC25. Поэтому я заказал QC25 вместе с сайт FiiO BTR3 адаптер Bluetooth. В QC35 Bluetooth нет может где поблизости сайт FiiO BTR3 адаптер Bluetooth в функция Bluetooth и качество звука. BTR3 имеет все БТ протокола, в том числе кодеков aptX, aptX декодирование-низкая задержка, поддержка кодека aptX-в формате HD, поддерживает, Хва и даже еще один вариант и с выделенными 24бит ЦАП и усилитель для наушников. Стоило только РС.4,500. Таким образом общая стоимость будет меньше, чем РС.16,000, который очень меньше, чем РС.35,000 QC35.пядь>

Если вы хотите проверить, что я имею в виду, услышать, Эрик Клэптон плейлист и вы бы знали это. Распределение веса идеальное. Упаковка настолько премиум, вы знаете youbhave купил наушники премиум-класса с момента открытия коробки. Я надеюсь, что это работает в долгосрочной перспективе. Даже если не имеют возможности беспроводной связи, как на новых моделях, это не так много, чтобы проиграть. Большую часть времени мы услышим принес наши телефоны, что бы быть ближе к нам. Так как телефоны имеют разъем для наушников , это было бы прекрасно. Даже если телефон не имеет одну линию новым айфоном , ЦАП всегда адаптированы является лучшим вариантом, чем беспроводной, если вы хотите, чтобы ваша музыка чистейшей лучших.

звук хороший, но не отличный. Четкость отличная, но минусы довольно плоский. Я слышал, что лучше в других наушниках, как высокого класса Сони. Но я использую его почти весь день подключен к ноутбуку, и комфорт имеет аналогов. Включите ЧПУ и большинство низкочастотных шумов нет. Однако, голоса и высокочастотные шумы все равно будут отсеяны, но на терпимом уровне.
Если вы ищете для всех день комфорт для длительных сеансов, ясность в разговоры с приличным НК и в вокал и рок-музыка, бегать по сниженной цене. Однако, если вы хотите музыка оживают и любви немного баса и поп, EDM и т. д., вы можете быть немного разочарованы. Хотя для меня, я не мог бы попросил лучше для моих конкретных потребностей.пядь>

я использую это на некоторое время с моим ноутбуком и iPhone 7, для просмотра Netflix & премьер-видео (аудио источника-это все равно гениально) и прослушивание музыки на Prime музыка, опять же, источник звука отличное, так что у меня есть приличный опыт в наушниках, с хорошими басами и хорошие средние частоты. Но при включении активного шумоподавления, опыт есть в другой лиге - вы не будете слышать любой голос в вашем районе. Я испытал это также в несколько рейсов. Даже если вы просто включите подавление шума, без музыки, это даст нереальный опыт, вы не сможете услышать в салоне полета шум (двигатели и т. д.)

а теперь о самом продукте
это мой первый премиум наушники после использования наушников стоимостью максимум 600 баксов! Поэтому мне пришлось дать много думал, прежде чем тратить 12000 баксов на наушники! Но деньги потрачены не зря
и шумоподавления работает, как по волшебству, как только вы включите его все белый шум просто исчезает

Testing procedure – while it's not scientific I spent a lot of time with these products listening to a wide array of music. I left the headsets on my head for hours on end while exercising, doing household chores and flying across the country on commercial airlines. Also, it took me several months to write this review as I continued to test and compare the Bose and Beats with a huge library of music that ranged from Eminem to Emmylou Harris. I used an iPad, iPhone and a couple of different iPods as audio sources since that's what the majority of us use these days. The songs are Apple AAC files sampled at 256 kbps.
BUILD QUALITY
(Winner) Bose QC-25 – The materials that Bose uses in the construction of the QC25s are absolutely first class. The plastic feels solid and the aluminum feels like it was intended for use in an aerospace project and the padding on the head band is thick padded velour. One issue is the fabric used on the top of the headband. My wife's headphones are the cool looking white with tan ear-cups and teal accents and cord. The white fabric can get dirty really fast. Bose is very aware of this because when I asked an employee at the Bose kiosk at Lenox Mall in Atlanta about it, they told me, without hesitation, that a Tide stain wipe cleans it up nicely. That area should be leather, plastic or aircraft aluminum, not white fabric. The black version will not have this issue.
Beats aren't too far off in build quality but they fall short only because they feel a little more "plasticy" and fragile when folding them for storage in the included case. The shuttle buttons built into the beats logo on the left side feel a little "clicky." Compared to the previous generation of Beats, the new Studios are a lightyears ahead in build quality. While I am testing the wireless version of the Beats Studio, they still come with cords, lots of cords. The one that I use most (to extend battery life or plug into non-bluetooth devices) is the one with the shuttle buttons. The cord is thicker than the Bose and is less tangle prone.
COMFORT
(Winner) The Bose QC25s are the lightest weighing and the lightest clamping headsets that I have ever put on my head thus making them the most comfortable, especially when wearing them over long periods of time. After wearing my Beats Studios for 20-minutes I put on the Bose and they felt funny they were so light. In reverse, after wearing the Bose for 20-minutes, the Beats felt noticeably heavier.
To put numbers on the weight:
• Bose 196.6g
• Beats 260g
Another win for the Bose is the depth of the ear cups. They are deep enough that people with large or protruding ears will not have an issue. In contrast, the Beats ear cups are much shallower. They are so shallow that my small, non-protruding ears touch the foam pad inside the cup. It's a minor annoyance will bother some people.
SOUND
This is what we buy headphones that cost over $300, right?
(Winner) Beats Studio Wireless. Beats products are well known for their huge, Hip-hop bass. In early versions Dre and Company made the bass more of a novelty rather than a quality audio asset. Fortunately, they reeled in the bass when designing the Studio models. The bass is now lighter, tighter and so well controlled that it's much more pleasing to listen to across a wide range of music.
Bose is not known for bass and the QC25s live up to that reputation. They are on par with the QC15s they replaced but that's not saying much. Where they shine is in the mid range, exactly where the Beats are weakest. The highs and lows sound muffled compared to the Beats but mids are more revealed.
Bose produces amazing, but slightly muted, vocals and smooth instrumental tones. Close your eyes while listening to both "Beethoven's 5 Secrets" or "Kung Fu Piano: Cello Ascends" by The Piano Guys and you'll hear a cello sing with such a mellow baritone voice that it'll feel like it melts like butter into your ears. I played "Cello Ascends" for a co-worker to get his opinion of the two headphones. When using the QC25s, he sat there with his eyes closed totally absorbed in the superbly reproduced music. When the song had finished playing he pulled the headphones off and with a huge smile said, "Wow. With the noise canceling on, I totally forgot I was at the office. You can get lost with those things on." I felt that was a solid review of the Bose when listening to songs that deliver mellow, mid-range audio that don't have demanding bass.
But, if you go back to Sam Hun

Design:
The design of these headphones is absolutely superb. They plastics feel very sturdy, and they have yet to be scratched. I never worry about these headphone getting damaged simply because of how solid they feel. The headphone cups rotate to lay flat when around your neck, but they only rotate about half that in the other direction. This has never been a problem in any way for me. One thing that I really like about these headphones is that when I use them just for the noise cancelling, there isn't a massive gap on the side of my headphones where the cable plugs in. It does not effect anything except for the aesthetics. The outside of the headphone (with the Bose label) is made of some sort of metal, presumably aluminum. This also adds to the overall aura of quality that surrounds these headphones. Another thing that I really like about these headphones is that the headband no longer has leather wrapped on the top. While it looks and feels great at first, after a few years this leather starts to break down and flake off. Again, it's not the end of the world, but it doesn't look the greatest when it happens. The cloth on headband of the 25's feels very high quality and seems like it would be very easy and simple to clean, if need be. Although these headphones are slightly heavier than my old AE2's, even after 6+ hours I can barely tell that they are there. As is with all Bose around-ear headphones, there cups feel heavenly, and are easily replaceable. These headphones definitely feel like they are designed to last.
Sound Quality:
As I mentioned earlier, these headphone are a marked improvement in terms of sound quality over its predecessor. They don't feel "closed off ", as the 15's do, and they are definitely louder. When the noise cancelling is off the sound quality definitely drops, but it is still better than a lot of headphones on the market. The biggest difference between having the noise cancelling off and on was the volume of the music. I would definitely recommend listening to music with the noise cancelling on, otherwise, what's the point? Overall these headphones sounds great. I am not saying that they are the best sounding $300 on headphones are the market, but they are way up there. An important note is that while there are better sounding headphones out there, none of them can boast the level of noise cancelling that the 25's do, and that is a huge deal when yours on a bus or plane, or somewhere generally loud.
Noise Cancelling:
When compared to the 15's you would be hard pressed to notice a difference with the noise cancelling. Not to say that the noise cancelling needed improvement, but if you're buying these headphone just for the noise cancelling you might want to consider the 15's if the $300 price tag seems just a tad too high. That being said, I love the noise cancelling on these headphones. They block out all of the low frequencies, and drastically reduce the volume of higher frequencies. The result is that you will most likely be able to have a normal conversation with someone while wearing these (no music of course). I use these headphones at work when I am down in the shop, and I never cease to be impressed by these headphones. When I traveled to London a couple years ago my girlfriend and I could have a normal conversation while wearing these (she has the 15's), when no one else could hear us. I also wear these headphones a lot in the car (not when I'm driving, of course), and they make a long car ride a heck of a lot more bearable. Also, as I mentioned earlier, the greatest thing about the 25's is that your music always sounds great, no matter how loud it is around you. When is comes to noise cancelling, Bose is the best.
Battery and Case:
As for the battery, I seem to get right around 35 hours on a AAA. The case also has a very convenient spot for a spare battery. The case is the perfect size, and it fits almost anywhere just perfectly. It is much better than the QC 15 case. It is a semi-hard case, which is good for finding a place to put it, and since the headphones are so durable themselves, the case definitely does not need to be hard.
Overall these headphones are great. The design, sound quality, battery life, cable and case are all superb. I would definitely recommend these headphones for anyone who loves music, and ever has to be in a noisy environment (i.e. everyone). This is definitely one



While I may not be an audiophile, I think I have fairly sensitive hearing and like well balanced frequency response curve and can note subtleties in soundscape and distortion, especially compression induced distortion.
I've had a pair of Sony 7502 headphones many years ago and liked them, but they were uncomfortable being on the ear headphones.
I've been able to sample a variety of cans at work including, Audio Technica 50x, Sennheiser 280, Sony 7506, Sony MDRV6, Sennheiser 202. Bose QC25.
Most important to me is a relatively flat very broad frequency response curve with good extreme lows and highs. If the sound is colored at all, I tend to prefer a gentle boost at low bass, <50hz, I dislike mid to upper bass, and like clear highs.
In my survey, the Sennheiser 202 sound awful. Its well outside of this price range at $25, so maybe thats why.
The rest I think sound excellent. My personal favorite is the Sony 7506. For $80 its hard to beat. The frequency response curve does not seem to be ruler flat to me but where it deviates it does so in the way that pleases my tastes. It suppresses bass from around 50-200hz, then has a slight rise on the high end to make the cans overall sound brighter than the rest.
I would have stayed with the Sony's except that their noise isolation is not very good in my office setting. A worse problem for me is that the Sonys cup material squeaks against my glasses making a disastrously loud sound when I'm trying to enjoy some music.
My next favorite is the Sennheiser 280s. They have much better isolation, similar feel to the Sonys with the same slightly deflated mid to upper bass around 50-200, strong low bass and pleasant but not overly bright highs. They're ok comfort wise but seemed a little tight on my head.
The Audio Technics seem to be a favorite online and in the office, but I found them flatter sounding. They also exhibit a dip in the bass but it extends farther into the mids, roughly 60-1khz. They sound fine, but I prefer the others and the other cans are less expensive.
However... I also purchased some Bose QC25 so use as a benchmark. My initial impression of the sound is that its blander than the Sony. I ran audio tests on audiocheck.net with all these headphones. With the Bose, to my hearing they have a completely flat frequency response curve all the way from 20hz up to 10khz.
But the sound isn't quite as appealing as the Sony 7506. I've spent some extended time trying both headphones at home and at work and have been surprised by my findings.
I originally started out looking for the best sounding headphones, but after a while I discovered that I actually valued quiet even more.
Basically I've fallen in love with the idea of noise cancellation. The Bose are so amazingly quiet. An incredible cone of silence. I can hear all the little nuance of quiet music that simply isn't possible at my hectic and loud office and home with several active growing boys. I found myself listening to music at lower and lower volume. At one point I realized I was listening to music at a lower volume than the background noise in the office. That was amazing to me.
The sound of the Bose is very good although less than ideal for my personal taste. However I notice very minor tweak on an equalizer, only a couple of db push on the highs and a couple of db reduction of mid bass, maybe a little push on 30hz bass and its perfect. Its also very listenable without any equalization.
Its possible that I sometimes here a little distortion introduced in certain frequencies and scenarios, but I haven't been able to confirm.
The headphone itself is extremely comfortable. More comfortable than any of the others I've tried.
Bottom line, I don't really have any complaints about the Bose other than the shockingly high price. I can't believe I've gone from considering $25 headphones to buying a $300 set of headphones.
My dilemma now is if its really worth the money. Ive decide that the quiet is more important to me than sound quality. So ANC has become a must. There are Sennheiser 450s, Audio Technica ANC7, 9, 70. But reviews on all the others don't sound as good as the Bose, so I'm very tempted to just stay with the Bose. Excellent class leading noise cancellation and very good although not perfect sound.

There is some incredible ear buds for $50 - $100 that deliver sound quality almost on par with these headphones. However, they are ear buds...they require very little power to produce sound, as the bud is soooo close to your ear drum. Good for reduced power drain on your device, but, bad for your ear drums. Also, with ear buds, since the sound is so close to your ear, certain sounds can become overwhelming, while other sounds appear to soft.....this is a consequence of having the source so close to your ear drum, its just the physics of sound fall-off, .... then, the buds slip in and out of your ears constantly, changing the sound profile...the cord can get yanked, jerking them out of your ear, or changing the direction they face in your ear... all in all... ear buds offer the smallest size listening apparatus, with the biggest sound, for the lowest cost... .PERIOD!
However, not everyone enjoys ear buds, I am one of those. I much prefer headphones for both comfort and I prefer the sound NOT so close to my ear drums. But to generate equal sound volume to your ear drum with headphones, the power draw required is significantly greater, as sound volume falls off by the inverse of the square. This is significant. In the past, makers of headphones had to limit volume, otherwise the device would have its battery drained too fast, and customers would reject such a product. So while I have bought many pairs of high end "device" headphones, one thing they all lacked was volume... if u don't like it loud, this is a non issue. However, loud is not "head banging loud" with these devices, instead, its just normal kind of loud. So while I "like" many of the headsets I own, including several Bose models, (Bose has been hit or miss with me with all their products in the past) .... they ALL lacked in volume... so it was a love / hate relationship for me with headphones for devices. Till now.....
The Bose Quiet 25 raises the bar, and IMO is the top-of-the-line listening apparatus for devices. Bose engineers seems to have thought of everything with the Quiet 25 headphones... here is what I love about these headphones....
1) Volume - is as loud as any ear buds, as they use a single AAA battery in the headset to provide the added power required to raise the volume without compromising sound quality and draining the devices power! The battery is NOT required for use, however, the volume and sound quality is noticeably less without the on board AAA battery. Battery life is in the 30 hr range, and has an on/off switch on the headphone. A green light advises u its switched ON! Not only is the volume louder with the battery power on, the sound profile changes from old fashion stereo, to more of an arena feel. SUPERB!!!
2) Sound Quality - with the battery in and powered on, the combination of added power and noise cancellation.... it simply provides the BEST and loudest sounding quality sound I have heard of any device listening aparatus... hands down!! I am spoiled for life!!! While good ear buds can match the volume, they can not match the range of lows and highs, as the buds are simply too close to your ear drums....so that added 1.5 inches of distance makes all the difference in this regard!
3) Noise cancellation - under the right circumstances, its very effective.... ur mileage may vary with this...but its the most incredible technology...not perfect, but very helpful. For example a kid screaming next to you on a plane, u will still hear the scream, assuming its short.
4) Comfort - most comfortable portable (device) headphones I have every felt... love them. On par with $300+ headphones for audio systems (non device type). Super soft leather around your ears with deep sockets so your ears are not smashed.....speakers set back far enough that gives the sound an arena like sensation!
5) Cord is plugged into the headphone via standard jack.... ever yank the cord by accident? You will not ruin your expensive headphones, as the cord will simply pull out of the headphones vs. being severed. Also, it comes with airline adapter as well...
6) Cord controls - Finally, Bose got it RIGHT! Yep... full music control, pause, song advance, song reverse, fast forward, rewind...and with the same 3 buttons, it serves as phone answer, switch caller,

The previous two headphones I have owned have been in the $50-$100 range and were the
PanasonicRP-HTx7-G1 $50
Sennheiser HD 212pro ($100)
While I really liked the previous headphones mentioned above, I now realize the gap in quality now that I have the Bose headphones. My review includes the following sections - Audio quality, Build quality, and Comfort.
AUDIO QUALITY
Firstly, the noise cancelling capabilities are ridiculous (in a great way) . Even without switching on the noise cancellation, the headphones do an amazing job of eliminating sound from around you. I did 3 tests of the noise reduction without any audio input.
#1 beside my tower computer (which has 3 large fans) - result = silence
#2 beside my air conditioner - result = silence
#3 beside the washing machine and clothes dryer (both running) - result = silence
To do a fourth test I asked my son to stand in the laundry room with the headphones on while I had the noise cancellation switched off. Then I turned it on and I watched disbelief and joy sweep across his face, as I am sure it did when I had done this test moments before.
Secondly, in relation to the audio reproduction, I wanted to assess the quality in 3 areas - Bass, mids, highs.
For the reproduction tests I went to Youtube on my computer for videos with test audio with the search term Headphone test Music.
The first test was with the video - "Sound Test for Beats by Dr.Dre - SkillGamingHDI"
This video has a strong bass component but weak mid and highs to speak of. Despite that, it still does an impressive job of giving the headphones a workout.
The second test was "Bass and surround sound test" Nice results but I feel the audio itself is not high quality.
The 3rd test was "Beethoven's 9th - Ode To Joy | Dolby Headphone 3D sound from Immortal Beloved HD 5.1" Gorgeous quality audio source file and gave each range of the headphones a workout, where they all excelled.
The 4th test was sorely focused on the low end response and was validated through playing the track "Ultimate Dubstep Bass Test"
Lastly I decided to bring up a favorite artist to reach for extreme bass, while still having a balanced range of mids and highs to assess - for this I listened to Deadmau5 4x4=12 (Continuous Mix) .
Since the majority of my daily use is movies and not music I then went to Netflix and looked some movies including some of the most recent releases (for potentially better audio content) to test. Here are the results but remember, results are also dependant on release date.
Black Hawk Down - Release date 2001 - Dialogue 9 - Action Sequences 9 - Music 9- Atmosphere (distant rain, breathing etc) 9
Marvels Daredevil - Release date 2015 - Dialogue 10 - Action Sequences 10 - Music 10 - Atmosphere (distant rain, breathing etc) 10
The November Man - Release date 2014 - Dialogue 10 - Action Sequences 10 - Music 10 - Atmosphere (distant rain, breathing etc) 10
Overall a score of 10/10
From my LG android phone the audio was not as brilliant, but that is a function of my phone and not the headphones
BUILD QUALITY
A typical area of concern for me in headphones is the build quality, especially around any joints or any area that moves.
I was delighted to see metal hinges which are embedded in rather thick plastic. I do not anticipate any breakages in normal use of the product.
Fabric covered headband - while this black fabric feels nice to the touch, I think I would rather leather or another material to reduce the potential for the accumulation of dirt either from hands or hair
Overall a score of 10/10
COMFORT
Again, for me I wear headphones for many hours a day, so this can be a deal breaker. These fit perfectly, and in no way hurt my ears or present any negative elements from a comfort perspective - they are a joy to wear.
Over all a 20/10
PROS AND CONS
Pros
Sound quality
Build Quality
Comfort
Includes Headphone adapter for inflight entertainment that requires the two prong connector
Includes a battery so the unit can be completely operational straight out of the box
Includes and beautiful carry case that accommodates the headphones when they are folded up
Inline volume and play/pause button for controlling audio on the phone
Inline mic for phone calls provides great clarity for the person listening on the other end
Cons

In the past I have always used in ear monitors (Shure E2C, Shure SE-315, Shure SE-215) whenever I have needed a pair of headphones, The sound is fantastic, they are low profile, and they have the absolute best sound isolation, bar none (they function as earplugs and are 'passive' rather than active noise cancellation which mainly filters out the sounds of motors, fans, etc.).
After a month in medical school I realized that I needed a more comfortable pair of headphones that I could have in for more than a couple of hours at a time while listening to lectures. Enter the Bose QC25. I ordered them the day that they were released and upon receiving them and plugging them into my laptop I was blown away with how comfortable they were for extended periods of time.
In terms of sound quality, these headphones are decent, but at this price point they should be a lot better. The bass on these is underwhelming- and I say that as a person who listens primarily to country, folk, and acoustic music. Mids and highs are decent, but still nothing special. The real draw to Bose is the sound cancelling capability: that's where these headphones really shine. Be it on a plane travelling, in a room with a loud fan or air conditioner, the active sound cancelling feature really does work great. They won't do anything for voices or most other non-mechanical noises, but neither do any other active noise cancelling headphones.
So, why did I rate these headphones only 1 star? Within a month, the right ear piece completely stopped working. Not once were these headphones exposed to water, used while working out, or thrown or jostled around. They literally went from their case to the library where they sat on my head and then back to their case. Whether I turned the noise cancelling on or off, there was little to no sound emanating from the speaker on the right. After an absolutely abysmal experience with a customer service representative who took two months to receive the headphones, refused to respond to requests for updates, and finally responded back to me the day they were sent back with an email that they were repaired, I was excited to finally have a working pair of headphones again. However, when I received them the note on the package said that they were examined and nothing was found to be wrong... but still there was no sound coming from the right ear piece. Had the incompetent individuals in charge of examining the headphones taken 10 seconds to plug the headset in this would have been blatantly obvious.
Again I got in touch with Bose, outraged at this experience. I was told to send them back and a brand new pair would be immediately rushed to me. While at the post office sending them back I ran into another individual who had the same exact experience as I did- purchased from Amazon, had the right ear piece stop working after a month or so, and had an identical experience with customer service.
Once I received the new pair of headphones I was relieved when I plugged them in and found them to work as expected. Everything worked great for a couple of months until one day I ran into the same exact issue with the right ear piece. No sound, no noise cancellation... nothing.
Bose products rely upon their image to sell. Any other brand that shipped out such a consistently shoddy product with subpar performance would be ripped apart in reviews, however Bose has an undeserved reputation of being a premium, quality brand among the general public. Not only is this product the absolute antithesis of this reputation, the customer service is one of the worst I have experienced.
If you are looking for a pair of good over the ear headphones, look else where. At $300, these headphones should perform at a level multiple steps above what they actually do.

I've had the triple black of these for a few days now and they are just what I expected. Comfortable, good design, good-very good sound quality and excellent noise cancellation. I currently have the Grado SR80s, Audio Technica ATH-M50, Sony XB-9590BT, Sony MDR1NC and generic apple earbuds.
Comfort: I use headphones at work, grocery shopping and during travel for extended periods of time and this is paramount. Only these and the Sony XB were the ones that did not put too much pressure on my head or ear areas. The Sony's had big plush leather pads that were prone to oiliness and sweat lot more than the QC25s are. The QC25s are lightweight and provide a good seal around the ears and there is more than enough space inside the headphone cup for your ears to not touch any part of the headphones. The lightness also doesn't put too much pressure on the crown of my head.
Design: The QC25s are sleek and look amazing. Apart from the generic apple buds, I wouldn't use any of my other ones in public, just at home and at the office. These look good walking around in the city, solo shopping, travelling and pretty much everywhere. Due to the pricey nature of these, I would not use these at the gym in the fear of yanking, sweating all over them. The case for them is ideal as well, with a space for a battery and airplane adapter. The materials are mostly plastic but they don't feel cheap at all, the headband material is a nice suede which feels luxurious and I can hypothesize that it will probably hold well for a number of ears with good use. I have the triple black model and I have been reading the few negative reviews for these about sound not working in one of the cups etc and I did realize before buying that,they seem to be confined mostly to the black models and some on the white models. Therefore, I surmised that they might have resolved their build quality problems before releasing the special edition triple black model.
Sound Quality: OK right off the bat, the sound clarity and stage is not as good as the Grado's or Audio technicas. They are not as loud as them but maximum volume is just silly in headphones. But the grado's and ATH-M50s were uncomfortable on my head for long periods, with the grado's giving me itchy/irritated ears from the pads within minutes. For my taste of music (classic rock, soft rock, acoustic, voice, pop, jazz, instrumentals and classical) they sound really good and the loudness on them is satisfactory for me. The detail and clarity is there as well as the sound stage. This is all in the noise cancelling mode enabled, as with other reviews I do agree it becomes dull without NC enabled, but its better than nothing so that's one up from the predecessor. One CON from these is that there is a bit of noise leakage, we have an open plan office and sit in quad desk formations, and my coworkers could pick out music playing at about 60-70% volume, so I tend to stay at 50-55% and it seems to be okay in that regard. Out in public and at home they are good on higher volume settings but I never go above 75%.
Noise Cancellation: These blow the sony NC cans out of the water and are surpass the isolation created by the ATH-M50s at similar volume levels. The effect when you first try on noise cancelling is spectacular, it feels like your ears have popped and everything is silent, you can't even hear yourself breathe. With only NC turned on you can pick up on close conversations but once there's music playing, even at a low volume, it's just you and the music. I still have to use these on an airplane but I have a few trips coming up where I can try these puppies on! the AAA battery feature is neat and a far better alternative to recharging lithium built in batteries and with 30-35 hour rated life on a single battery, it should last all week and/or a few plane rides.
Overall, very happy with the purchase and I will update this review later on with more use of the product and after using it on flights.

I've never owned anything Bose related, and my only experiences with Bose have been limited to store tests and my grandfather's sound system. I have upgraded to these headphones from a pair of Behringer HMP100s BEHRINGER HPM1000 that have served their purpose well. (Yes, it's a significant jump) I have worked with pretty nice headphones before, some mid-end Sennheisers and the like, but never Bose.
I work with video and audio mixing/editing, as well as manage a podcast, so all I really look for is clarity and comfort. Needless to say these are very comfortable. They're soft while tight enough for them to feel like they're not going to fly off, so that's a plus for me. (I do tend to go out for runs, and the haven't so much as shifted on my head.)
So, as far as sound quality goes, without the switch on, they sound as good (If not better) than the Behringers, while sounding massively better with the cancellation and amp on. I'm noticing little nuances in music I have never heard in music I've not noticed (or been able to hear) with my other headphones. Though if you have the amp on, there are occasional times where I can hear a slight ticking with bass, but it's not consistent with every kind of bass I've heard, it's rather hard to describe. A lower-quality song with a more direct bass will case a slight rattle, but a higher-quality version of the same song won't have the same rattling. Also there is a small amount of sound-bleeding at mildly high volumes, but it isn't loud enough to hear outside of arm's reach. I'd say at 3/4 volume, the radius of being able to hear sound leaking would be around 6', give or take.
The cancellation: Alright, I always like things that have noise isolation. Isolation is nice, but I've only owned one set of active noise cancelling headphones and they were 'meh' at best. They wouldn't quite filter out road noise, while these will block out things like a generator running, construction noise, dogs barking (Provided they aren't right in your ear), and so on. I'd definitely recommend them on that basis alone. There are a couple of little quirks I've noticed with the cancellation, nothing dealbreaking or anything... like for example, if you're sitting in a car, and someone opens and then closes the door, the resulting 'whoosh' does seem to confuse the cancellation a bit as whatever I'm listening to will stutter for a second.
Comfort: I haven't noticed any sort of fatigue or unwelcome pressure even with glasses on. They are also secure enough not to fly off, even with rapid head movements. They also feel rugged enough to take a drop or two without shattering, and that's always a plus for me.
So, all that to say: As a first time Bose owner, I'm satisfied. They deliver on everything advertised, and met my expectations.
I'm not sure I'd recommend them to someone that's just looking for a minimal good pair of headphones for the price, as they are to meet a specific criteria. If you can spare the cost, enjoy music, and also enjoy quiet to the extent of considering them, I'd say go for it. If you're just looking for something expensive for bragging rights... well, that's entirely up to you.
A couple of things to note: if you have lower quality MP3s, you will definitely notice. And these do NOT play well with any sort of bass boosting. They have a good amount of bass on their own, but if you add in extra bass they may very well start rattling like crazy.
Oh, and if you're the kind of person that tends to shout when you wear headphones, I'd approach with caution. With the noise cancellation on, it's pretty hard to hear your own voice. I'm softspoken, and never really talk loud to begin with, but I let some relatives try it on and that resulted in yelling worthy of a sports stadium... Then again, that's not really Bose's fault, and just a bit of a personal note.
I hope this helps. (If I missed something, I'll try to answer questions as best I can)
