If you have a bluetooth headset then sadly it looks like you’re out of luck in terms of voice chat on the Playstation 4.
Sony confirmed this point to Game Informer just last week, and unfortunately if you’re planning on using your current bluetooth headset with your new console it won’t be possible.
Alternatively, if you have a device that uses USB for chat function, you will be able to use that with your new PS4, it just won’t be from day one. Sony intends to release a system update for the console in order to make them compatible.
And finally, if your headset uses digital optical for game audio, you will be able to use it to listen. You just won’t be able to chat, yet.
