I bought because of price and the unobtrusive mic. I use for PC gaming and find the sound on whole of good quality although there is an issue of feedback on entering and leaving game, often requiring a new sound source to make it stop. It is good at cancelling external sounds.
The microphone is disappointing leaking game sounds back into voice channels using Teamspeak/Discord servers. Found getting the right capture level very difficult either ending up too quiet or transmitting other ambient sounds rather than just voice.
The headband creaks whilst being worn and I find it uncomfortable after hours of use, but as a glasses wearer the pressure on spectacle arms is not too much.
I so wanted to like these but just too many issues that add up to a poor product in its current form.
