A:AnswerThe only thing I can tell you is that your headset battery might be dead. if not that then you should try checking your audio settings on the ps4.
Sorry for any inconvenience
A:AnswerThey charge via USB-C. The headset comes with a USB to USB-C charging cord which can be plugged into anything: Wall outlet, USB car port and pretty much anything else.
Very easy to charge though and they hold their charge exceptionally well. Get em ' you won't be disappointed
A:AnswerYes, even if you can't connect two dongles, the headset comes with a way to plug directly into the controller. I don't think the microphones work, but the sound works just fine.
A:AnswerTry checking if the cord is wearing out, if using wireless then yea its dead, see if you can find a replacement piece since they are easy to pop off and change.
