Playstation 4 PRO and Virtual Surround Sound "7.1" besides Thresher 7.1?

Hi, I have too big of a head, and a lot of headsets just plain small to me, and some other when technically "can fit" are actually really uncomfortable. This, very sadly, includes Thresher 7.1. I tried on and liked Kraken a lot, though I haven't been able identify the exact model (store used them as headset for demo gaming laptops and didn't have specific price tags on them, while those were clearly one of the Krakens (7.1, or v2, or Tournament)). I also liked Kraken X, fits well. What I cannot understand is if there is any Kraken model that supports "7.1" on PS4 Pro like Thresher 7.1 does? Are there any other Razer headset beside Thresher, wired or wireless, that support "7.1"? What does it ever mean for headset to support 7.1 on PS4 Pro?
