Virtual reality vs gaming headphone. (Half-Life: Alyx)

Unfortunately I do not see anywhere a normal discussion HL Alyx, either here or on the popular dota2 or the forum on steam. But you need to discuss this topic and perhaps write a petition to Valve.
I'll start with the title of the topic, in games, immersion and visualization are achieved by a gaming headphone and surround sound. Column lose the headphones when I play Skyrim, Stalker and far cry 4, thanks to stronger gaming headphones are immersed in the game world, hearing steps in the same cs: go. And I think VR is not needed here.
The second problem is the exclusivity for PC VR. Wanted to another PSVR was HL Alyx.
The ratio Valve to gamers, like they have room under VR sharpened? But who needs this VR, it is better to go somewhere, to the gym, for example.
