It looks sleek and small but those dual armatures are really pleasing to listen to because of the non-fatuiging sound. Vocals are well pronounced and caress the listener's ears with good imaging and separation.
Bass performs admirably well, with enough warmth and punch. It's very tight and has enough impact for most genres of music. It doesnt go down deep, but for non-electronic genres it will do well.

I prefer it over the DBA02 and UE700 as unlike those IEMs, this one is very balanced and has all frequencies represented equally in your music. I also like the non-fatiguing sound which means I can listen to music for the whole day without getting tired of piercing highs and sibilance. I think of it as a DBA02 without the piercing highs, which in turn brings out the bass.
