I compared my M22Ti's to M22 v2's and the difference was really only noticeable when I A/B'd them. I couldn't really tell much difference having heard the v2's previously in a friend's house. I was curious and we decided to try them side by side. I would expect the difference to the v3 would be similar, only really noticeable with an A/B comparison.
