Using DBA-02 MKI here, for about a month now.
I have used some really nice IEMS, SF5pro, IE8, SM3V1, Sony EX-600, RE-252...and well I can say I was blown away by the quality of those!
I bought them for about 50€, and that is from far the best bang for buck I had since I entered high-end portable audio. That and the Clip+.
The bass is perfectly tight, and about the right amount. I thought I would find them bass light, but not so. The bass is there and goes to sub-bass...
