You could look into the
Cloud range of headsets from Kingston. I would rather advise you stick to stereo headsets since 7.1 surround headsets if powered through a USB are virtually upmixed to produce surround. If you want analog support and true surround sound, you could look into Razer's Timat headset but once you move to a smart phone, you're only going to get stereo.
So if anything, surround is possible on PC, on smart phone/PS4, it's stereo.

7.1 in headphones isn't a real thing.
It's as real as the air we breath.
