Here's an example for HEX v2, vastly different from v1. The HEX v2 has very similar sound to HEK, which if you go back in some of my impressions, I felt had sort of a "bouncy-bounce" quality. Now here is HEX v1 which I felt sounded softer and laid back. Definitely more damped. One thing I've noticed about many headphones that sound "soft" is that the first half wave is of lower amplitude than the rest.
