i know this is prolly a dumb questions, but i have been curious for years! say i get astro A40 (without amp) for PS5/PS4 primarily but can work on PC and other platforms! would that work the same as if i got one that’s specifically made for PC!? like is there any audio difference or anything or they preform all the same!?
If it has one/two 3.5mm jacks like the A40, that depends on the sound card. Nowadays all PCs have built-in ones that are about as good as what’s in a playstation so you’ll have to try hard to hear a difference. You might need an adapter to switch between the single 4pin jack and dual 3pin jacks though.
Bluetooth is a mess for headsets so avoid that. The proper wireless ones come with a dongle and have the same quality on all devices.
