Yes! The Arctis Pro Wireless headset works with both PS4 and PS5, even though the packaging doesn't specifically mention PlayStation5 compatibility.
To see the PS5 as the connection option in the Source tab of your transmitter, your headset will require an update out of the box. You can update the headset via our software, SteelSeries GG (Windows/Mac only).
If you do not have access to a PC, don't worry! You can still use your brand new headset with PS5 - simply select PS4 in the transmitter options.
How to connect Arctis Pro Wireless to PS5?
To connect the headset to the PS5, simply use the provided USB to micro-USB cable. Plug the USB end into one of the back ports of your console and the micro-USB end - to the transmitter.
Then, just press the volume wheel on the transmitter, go to Source, and choose either PS4 or PS5 based on your headset's update status.
