I bought the PX4 headset a while ago and don't have any complaints at all with them.
Hey guys joining the PS4 owners club soon and I am trying to work out whats the best headset to get under £150.
I just added to that thread as the older Sony Wireless Stereo Headset now works with PS4 and you can pick them up for £70. Yes they may not be as good as the setup you mentioned but a lot less hassle and no cables. Even the new Sony Wireless Stereo Headset 2.0 and the Pulse Elite can be found for less than 100 Quid.
Well I am now that mine work with PS4 or they would have been VERY limited in use.. 
face it mixamp is nowhere to be found.
