Yes, the VI Windows version via Proton is superiour to the native linux build. Steam Deck likely defaults to the native version, but that can be overridden with 4 clicks.

I wouldn’t consider Audio-Technica anywhere “gaming” related, can be pricey though.

I have a ATH-G1WL (wireless) and ATH-AVA400 (wired) and cannot hear any difference in sound quality what-so-ever, except the 3m cable I have to fiddle with now, which I also have to physically move when changing devices.

Bluetooth also sucks for mice and keyboard, so yeah…

You clearly haven’t used wireless headphones in last 10 years, have you?
