headphones not working on PS4

They don't connect at all? Is it intermittent? Either way, the wifi antenna probably needs to be replaced. I know when this thing malfunctions controllers drop connection and wont sync as well. That being said, your controllers probably wouldn't sync if that's the case so before you attempt this repair I would check other headphones first to make sure. Here's the tutorial for the wifi antenna Reemplazo de Antena Wi-Fi para PlayStation 4 Hope this helps!
