I also bought some from the Ebay Outlet for my kid to game with. The instructions were quite confusing and not hugely helpful, so I also struggled to get them working properly. But after some fiddling around they are working very well, apparently. They certainly feel good quality and sounded acceptable to me, but they do seem to have poor user ergonomics.
Got this from Argos outlet ebay for £16.45. It's good set of wired headphones, battery powered for a mic boost and possibly bass boost but no Bluetooth which is fine for PS4 as you need proprietary ones if you want Bluetooth headphones on PS4. I did initially have problems with the Mic but after constantly playing around with the PS4 sound settings and restarting both the headphones and console it finally worked! One other interesting thing is that it has three seperate profiles for PC, Xbox One and PS4. Oddly you have to hold down the power button for around 2 seconds to change between them which with most powered headphone would turn them on/off. Other than that, good sound and great other features like pressing the left cup for muting mic and very comfy.
I had issues with the mic on mine and had to return them. Hopefully it was a faulty product (not voted)
