I've had first hand experience with the new DBA-02 MKII. I must say. The build quality here is excellent, and the rubberized coating on the housing (that is reduced in size) is quite nice to touch. Owh and they're the size of the ER4p now. Soundwise still the same signature but not sure how much better or worse it is. I'd still take the GR07 (which has been my staple IEM for almost half a year) but the DBA MKIIs are worth a thought, and will top the GR07 in comfort and build quality this time around, and should hopefully pull away from the Brainwavz copycats.
