As soon as I put my headset or other headphones in you can hear a hissing noise when I'm talking, so I hear everything normal but the others only hear a hissing noise in the party. The funny thing is that it happened suddenly and it is the same with both controllers. That means that both of them should be broken at once, which is very unlikely. I've also cleaned the jack connector and reset a controller. I have already restarted Ps4. Usually I know a lot about this, but here I really have no idea how to fix it.
If you have another headset, probably one with Bluetooth, try it out to see if it is there. As it sounds, it will be a cable break from the headphones in the microphone cable. That's why you still hear everything.
