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.
face it mixamp is nowhere to be found.
