It now works... You'll need the Razer Audio app installed and the usb-c to usb-c cable that the speaker comes with. Connect the Leviathan to your ps5 using the usb-c cable then pair the device to your phone. Once connected to your phone open up the Razer Audio app and allow it to detect the Leviathan. Once it had picked up the connection you can fine tune your Leviathan including its input source. Switch this from Bluetooth to USB and presto. Your lovely Leviathan now works with your PS5 and comes up as a usb headset.
