I watched a video on the V2 vs V3 from the headphone show and the guy said at one stage that the V2 has more slam/impact and then later said the V3 has better slam/impact! That left me a bit confused. The frequency response graphs for both are very similar. I must watch a few more videos, but being that this used pair is half the price of a new pair of V3s, I'd say will get over it if it's a tiny bit different.
