The sound through the headphones is clear and has nice bass and completely wireless. I wanted this for Recording YouTube videos coupled with the HTC Vive. the audio recorded from the mic is acceptable but nowhere near as good as my old wired set.
For me 89 quid is expensive but they do sound great considering its wireless. Battery is micro usb and lasts about 10 hours between charges
I needed a headset to replace the Turtle Beach PX12 that I was using previously. These came without a bulky receiver/source-switching unit, and worked without any difficulty.
