I own a pair of these (not purchased through massdrop). Really like them. Compared to other ba earphones I own, they have the most honest treble response. They aren't artificially bright. Cymbals sound like cymbals really sound, not cymbals mic'ed an inch from where you strike it. As a result, the soundstage isn't enormous, but it's still really good. The texture of the bass is great. I find myself grabbing these more often than my other IEMs (IMR R1, Hifi Boy OS3, TFZ Secret Garden), partly because they fit well and isolate very well, but mostly because the sound signature works for me.
