I bought this
adaptor from Amazon for the PS5 because i already had these Sony XM3's like
@twosips has i think. I didn't want to fork out for new expensive ones when these are great tbh, and the adaptor works great. It also allows two connections, so i use one for the headphones and another to connect to my Bluetooth Soundbase. It also has a small 3.5mm adaptor that you put into the controller for mic use, admittedly i've not had a chance to use that yet so can't comment on quality of mic sound. But for anyone that wants to connect their headphones via bluetooth, this is decent.
It comes with usb-c connection as standard but also has a usb-a adaptor. If you connect it to the USB-C at the front of the PS5 then it covers the USB-A as well which causes issues if you want to charge your controller from the front. I find its best at the back, although it then takes up the faster slots.
