Poor, cheap, bad, etc.
Bad fit. Bad sound. I received complimentary headphones on a flight one time that were better than these.

Good Sound. Terrible everything else.
I don't know what else to say, other than that these are absolute trash. The sound quality is good. The same as any other Koss headphone with the same driver and earpiece. But literally every other aspect is bad. First, the clips. I have the wired Koss headphones with earclips, and those are much better clips. They have thicker, more rounded plastic that is much more comfortable. These have thin plastic with square edges that are extremely sharp and uncomfortable. In addition, the clamping force is way too high. It's legitimately hard to get the clamps over my earlobes, as they are just way too close to the earpiece. So, the clips both dig into your ear, and squeeze your ear, making them very uncomfortable. The bigger issue, though, is the battery saving (?) logic. As soon as there is any silence, either the drivers or Bluetooth radio cut out to save battery. And I mean after less than a 1/4 second of silence. So, if you're ever listening to anything like, say, dialog with no background noise, you will miss the beginning of literally every sentence. Not only does it take a split second for the sound to cut back in, but it doesn't cut back in. It slowly fades back in, over two or more seconds. This leads to you missing very large, significant portions of every sentence, and makes listening to dialogue literally an unusable use case. Gaming is just impossible. The vast majority of sounds are completely missed. I'm honestly baffled how these made it to production in the form they did. They are quite possible the worst headphone I've every used, even though they have good sound quality. Long story short, don't buy them. Under any circumstance.

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.

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.
