I didn't realise how uncomfortable the pulse 3D was until I bought my Razer Barracuda X, the difference is night and day. The pulse 3D had a weird burning sensation on my head after a very short amount of time.
I had a quick look at the Razor Barracuda X… looks great, also the 50h battery is nice. One question though, when you plug the dongle into the front USB-C port of the PS5, does it obscure the USB-B port above?
Why not buy any other Handheld with android that has probably more power, doesn't need to be jailbroke and remote play is anyways always possible. There should be plenty out there.
