Start laughing then, because it's true.
The Gold (and also the Pulse Elite) headset wakes up entirely just being connected to an amp. Be it a cheapo TB DSS or a Mixamp, doesn't matter. Give it a little bit of power and it sounds so much better than being wireless.
My understanding is that because the battery needs to be used when in wireless mode, the drivers aren't actually being fed enough current for them to actually work. This is to of course improve battery life and Sony can't afford to put in bigger batteries as they want to keep their headsets light.
So yes, it sounds significantly better when wired. It's not even a competition. Otherwise in wireless mode, every damn thing just sounds so veiled even at max volume.
Sony's VSS is nothing to shout about. If you want to know how it sounds like, take Dolby Pro Logic 2 and cut out 20% of the reverb. That's Sony's VSS.
