I had the Vsonic Gr02 Bass but it broke so I had to return it. I liked the bass on it but I found the overall sound slightly 'hollow' and slightly harsh on the treble side on certain tracks. Instead of getting a direct replacement I went for the R02 silver. I've never had mid-centric earphones before so I was just wondering does the mid over power the bass and treble at all or are they still clearly defined as well. I'm not a bass head but a for lot of the music I listen to (EDM) bass is a large componant so I just hope the bass doesn't fade into the backround with these iems. Also, any idea when/if you'll be reviewing the VSD1s?
