sold out :(
great deal imo, got mine from amazon a few days ago and they work great on the PS4 and PC, really comfortable for long gaming sessions too as stated already in the thread, youll need to update the firmware on the dongle if you want your PS4 to recognise it, youll most likely get 030 firmware with these which the PS4 doesnt recognise so you have to download the 010 firmware version onto the usb dongle and then theyll work really well with the PS4/dongle(volume etc)
Great headsets, I own the original Cloud headset and Cloud II's and they still work as they did 3 years ago. I'm always tempted to buy another set when I see them go on offer. I have over a dozen headsets and these are the ones I always go back to, they have the best balance of build quality, audio quality and comfort. It's a shame we never got open back versions of these.
youtube search: hyperx cloud 2 ps4 and you'll find 7.1 is possible.
These are consistently reviewed as being among the best for the price range despite competitors bringing out brand new models. I currently have a pair of headphones from Steelseries that were a similar price and my friend's HyperX Cloud II is comparably better. I'd be buying these but my current pair haven't died yet!
