I had the same problem and found the solution after a long search. You have to remove both hacks from the HS80 in the ICUE settings under Software and Games.
Yes, this headset is compatible with the PS5. It uses a wireless USB receiver to connect to the console, providing a high-quality audio experience. For a successful connection, be sure to set the receiver to PlayStation mode if necessary.
Unfortunately, we are currently receiving this headset very poorly. If everything works out, availability is expected to improve by the end of the month.
Disable the RGB on the side, it consumes a lot of battery even though you don't even see it. You can also deactivate the glow on the mic, which will certainly help a little.
Without pressure 2cm deep. The inner clearance is about 4cm wide and is cut diagonally at the bottom with a short side edge length of 5cm (back) and the long one of 6cm (front). Might be too small overall for very large ears. However, the pad is very comfortable on the skin and nice and soft. The pressure on the ears is low. I wear glasses and have zero problems with the earpieces. Very good audio quality. I have already been told that I can now hear much better. Maybe that makes up for it.
