Product Description

Koss turned the headphone world on its ears with the KC35: a pair of headphones that use earclips instead of a headband to ensure a snug fit and excellent portability. Taking these advantages even further, Koss has unveiled the KSC35, which adds Bluetooth 4.2 and a 6-hour battery life to its list of travel-ready features Read More

These have become my most used headphone. Though I did do the headband mod and added thicker Yaxi earpads to make them a bit more comfortable.

I had them for a while, I wish I could recommend these but can't.

noticeable latency in the audio, I assume it's because it doesn't support AptX or LDAC but I have SBC based devices with better response than this.
The ear clips aren't the same as the ones on the KSC75s, these are flat, sharp and made of plastic. They aren't adjustable or comfortable.
Micro usb, but I'm not blaming them on this one, it is a pretty old model of headphones.

I really wished these were KSC75s you can listen to wirelessly, but they are not as good in so many ways and just feel like an afterthought..

AsatiirHow’s the battery life? Looking to replace a cheapo pair in similar style that I put in my ski helmet. Audio quality isn’t such a concern but the battery craps our after about 4 hours so only about half a day on the slopes...

Can these snap into a PortaPro headset ?

Alan.RI don't own these but I'm willing to bet they do. The driver appears to be identical to the ones on the Porta Pro's. I actually took the ear clips from a set of KSC 75's, removed the headband from some Porta Pros and snapped on the ear clips. ( I prefer the warmer sound of the Porta Pro driver and the ear clips of the KSC 75's.) Btw, Koss makes bluetooth Porta Pros also.

Should've made them fully TWS. Forget about all the touch control and other features. Simply put cheap Bluetooth modules and batteries on the outershell, and called it a day! Keep the cost down, and It will be a lot more popular among consumers.

KumonomukouWhile I'm with you on that one, I'd love to see a pair of TWS KSC75s with low latency support. A TWS like that with (potential) modding support could very well become a daily driver. Maybe do a consumer model (as I think you're spot-on and that would be more popular), but also a "Pro" with better BT codecs for those of us who need low latency and/or hi-res?

It seems like it's SBC only and considering that it comes with Bluetooth 4.2, I'd like to know how is the latency by video streaming services.

I picked these up when they first came out a few months ago and they have that great Koss sound. Zero insulation and zero isolation (for those who never have had Porta Pros or the KCS75's), but sugar sweet bass. The chunky battery and receiver is a little awkward. It houses the mic too so I understand why they don't have it in the middle of the wires, but if you're wearing a collared shirt it snags on or gets buried. I wound up getting some true wireless earbuds from ADV. Sound (the excellent M5TWS) and I just use these for exercise so I can hear what's going on around me. 75 minutes is about as long as I can stand the clips so it works out.

These don't ship from drop for another month while being a whole $5 less than on Amazon where they will be in-hand in a few days. Yet another item I find on drop, and can't justify not buying elsewhere.

I REALLY wanted these for running. They sound great. The price is right... But that remote that dangles against your neck while you're moving around I just cannot handle. If they would design the remote in such a way that is much less intrusive and bulky then I wouldn't hesitate to buy it.

It's definitely some kind of logic, not just bluetooth. I'm using them on my PC, and I have a Bluetooth antenna right in front of my face like 2 ft away on my desk. And it definitely seems to be some sort of power saving logic. When I first turn them on, they're fine. Nothing cuts in or out, and it captures all audio. But then if I don't listen to anything for a few minutes, by say, going to the bathroom, going to get a snack, talking to someone, etc. when I start listening again, it has the problems. It's like it goes into a power saving mode after a couple of minutes, but it doesn't properly exit it when you start playing again. And there's just no way to fix it after that happens. I can fully turn the headphones off, then back on, but it's still in it's weird power saving mode and the beginning of everything gets cut off. You have to turn them off and then just not use them for an hour or something so they'll go OFF off. Then the audio will be normal again. Something about the power saving logic is just completely f*cked, and they've just sat on my desk since the day after I got them. They're completely unusable for my usage patterns.

Yea the clips are pretty bad on these, I've replaced them with KSC75 clips otherwise they were unusable. It's not `battery saving logic`, it's just bluetooth connection dropping out. You have to fix your devices so they're in direct view of each other so the sound doesn't cut out or just replace the source. There's also about 350 ms of audio delay on the device under Windows 10 so that needs to be corrected by the software, be it VLC or a browser extension for Youtube etc. Maybe another high quality bluetooth chip might fix this as I'm using my motherboards onboard Intel BT 4.2 chip. SBC codec also doesn't help as sound quality ends up lower compared to a KSC75 per se but it's still a pleasant experience as these headphones are really comfortable since they're wireless.
