holy...yes yes...these have a HUGE amount of bass 0.0! beating any earphone I've heard in the bass department. But the highs and mids are hiding atm. I hope it's a Denon story: in other words with burn-in they will shine, and then these will be my favourite in-ears Oh wow - just put the normals in vs the EXTRA bass ones, and you can hear a HUGE difference. The S's are less bloated with bass, and are much more open. Don't get me wrong still HUGE amount of bass Will report back when i have more time on these If they do improve with burn-in we have a winner lads!
