It fits me fine and "addictive" mids but its bass isn't how I hear you (andb others) talk about other iems with proper quality quantity bass. This doscino ziigaat with its tech looks promising in that regard . Not much sub bass here, mid is carefully done I guess so that it doesn't bleed on perhaps. But it doesn't rumble and growl. It's more bass than what I experience with P8s, sivga, zero etc but not as tight, tactile, and good as even say the quality of hd660s2 which isn't really a bass can . Hence am considering an iem that does bass well, just to experience it.
@Tamizhan I just put on Fan2 after a month of being bessotted with Sivga Nightingale.
Fan 2 Lovely depth in soundstage (but since the veterans here say subjective, so take my take in that prism).
Mids still fabulous and my preference for kind of mids in iems. Upper mids aren't shouty, and things tend to sound all balanced and flowy.
Warm neutral and musically pleasant to ears
Not much air relativelybut then that sivga goes overboard with that air, so I might be spoiled. Treble isn't Aful P8 quality for sure though.
@baskinshark can confirm or deny: I do hear the ba tone on acoustic instruments but not too jarring to spoil my pleasure. But it's there for sure imo andbi wish it wasn't!
But it would be more experienced reviewers to tell you how it fares, actually, in that comparison regard.
overall, at that discounted price, go for it. Can't see what else is this good or offers what this does in that bracket.
