The pros: Sound is the same as the porta pro models which I love. That bright blue flashing light on the porta pro wireless is not on the KSC35. No annoying bar across the top of my head. Bluetooth v4.2 vs 4.1 on PortaPro
The cons: clips pinch the ear after a while. The battery life lists as 6 hours vs the 12+ listed on the porta pro wireless. (never tested either. I just charge after a few days). The band with the mic and volume gets caught on back of neck so I wear in front.
On another note, so I could still use the Porta Pro wireless (as a backup) I ordered the KSC75 and swapped the ear clips from those and attached the Porta pro wireless speakers. Works perfectly
I recommend the KSC35.

These earphones and the Shanling MO will be my on the go setup this summer.


1) Battery level is not accurately reported (at least in android, not sure about others). I discovered this when they started beeping rapidly at around "50%" battery. Turns out this was the low battery warning and the battery level was just being reported incorrectly on the phone.
2) The cable is light and gradually pulls to the right due to the weight of the bt module. Other brands get around this issue by separating the battery and bt module into separate boxes on either side of the cable, thus balancing the weight. After a few uses, I've decided to simply let the wire hang in front and not around my neck.
Slightly annoying that I can't hang it around my neck. Having the wire hang in front works ok, but then it's no different from using a standard wired pair of ksc35/75 with a bt dac (which I am currently doing with a fiio btr5 in my shirt pocket). One of my main reasons for this purchase was for the convenience of hanging it over my neck.

I took the plastic clips off and put some KSC-75 clips on, since they just snap together (You can also do this with Portapro headbands). I also Kramer modded the grills, but they were sort of difficult to remove because a little glue was used to secure them in place. Finally, I put some PX200 ear pads on and they're as great as ever.
My other issues with these are is the wire and battery: the little remote/mic/battery is sort of awkwardly just floating there and annoying to use because it's out of the way. I assume this was a decision to increase battery life (even though the resulting 6 hours still isn't great) , but completely wireless Koss clips is an amazing thought. Airpods spoiled me in that regard.
To summarize:
Pros: Great sound and price, compatible with KSC-75 / Portapro parts
Cons: Cheap plastic clips, 6 hour battery life, awkward wire & remote

The main reason I rated these as 2-stars is because the headphones would constantly cut out during use. I tried it on both my laptop and my phone. I tried it with both video calls and with phone calls. No matter what, they'd regularly cut out, which makes them basically unusable for me. Again, at $50 I wasn't expecting much, but I was at least expecting the bluetooth to stay connected during calls. If you need these for any of the voice features, DO NOT BUY. Epic failure, KOSS.
P.S. The earclips on these are horrible.


overall, great value for the price, but maybe not the best option for audiophiles.

I'll just go over what I'd like to mention from my experience:
-Good, open back, sound quality. No isolation, but the sound bleed is minor. Good for vocals.
-Playback always fades in, giving you time to adjust volume if it too high to save your ears and eases into music nicely. It's a good feature that's missing on other headsets. Sometimes my audio source is fickle, so the audio drops out and fades back in every time the signal breaks (happens even with a bluetooth 5.0 source). Sometimes, the only way to fix the cycle is to re-sync to the source.
-Audio is slightly delayed; video playback will have lip-sync issues. And again, audio always fades in, so videos always start silent then increase to the set volume.
-There is digital assistant support (double-tap center button) or the ability to skip/repeat tracks (hold up/down vol keys) on the in-line remote. This is a nitpick, but the monotone that plays when the assistant is activated sounds almost like the device lost a signal, or if a phone call got cut off. Every other melody from powering on/off syncing and so on has some character to it, so it just seems a bit of an odd choice.
-Hair can sometimes get in the holes of the earpiece and create this squeaking/scraping sound until its brushed away... It's the only time I've experience this issue (most likely due to the open design).
-The earclips hurt after an hour or so of use, but not to the point of being unbearable. If these were made more comfortable in some way, they could easily be worn all day. On the plus side they don't shift around during a workout.
Overall good. Minor complaints aside, the KSC35 deserve five stars for their value;


Always avoided the 75s cause honestly they looked super cheap but finally bought them and really just wanted a wireless equivalent. These sound a lot more like the 65s and the kph30s then the porta pros which I really prefer. Only downside to these is the clip isn’t as mailable and comfortable as the 75s but sound quality is superb for a wireless 50 headset. Didn’t buy for the microphone so honestly can’t speak on its behalf.


Also $49.99 for something that usually costs $19.99 without an ear clip seems odd. But Koss is known for quality sound.
All in all I'm really happy there's finally some nice low profile BT headphones for people who can't wear earbuds, but it needs just a little more refining. Until then I'll enjoy these.




The major issue I have with these headphones is that they rub on the top and back of my ears and by the end of my workday they are quite painful and uncomfortable to wear. I wish I had gotten over the ear headphones instead of clips because they do not seem to work for me. I also wish the battery life was a little longer, 8-10 hours would be ideal.


They are going back.
