Koss KSC35 Bluetooth Headphones

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.

Well it's a bummer. I got the wired version and like it really but gonna skip this one.
