Before talking with Vance today, I was already sold on buying the WS5 headphones since I was told you could hear the sounds better by keeping the noise out better. Well Vance is trying to convince me that the WS4 with his adapter (I'm not sure what he meant for sure, I think something aftermarket) his headset sounded better than the WS5 headphones. Has anyone on here bought that setup from Vance MDing or know what he is talking about? Are they better than the factory setup? Thanks
