Phenomenal bass texture and quality. Mids are good if not great - I don't have much to nitpick about them - good note weight and excellent clarity. Treble is very sparkly and airy though some may find it a bit too much - I think the extra spice actually helps with instruments like violins. Imaging isn't quite as precise as U12T but stage is just as large if not more so. Timbre is not exactly natural but it is very good and definitely not offensive at all. My subjective favorite IEM to date. This is without a doubt a colored listen but it is so satisfying. Makes U12T sound almost sterile. That said both are good counterpoints to each other.

I usually don't like things that aren't all rounders but this might be the exception. Bass is incredible - best in class - great texture, fantastic physicality. Treble response is great too - pretty resolving. There is a noticeable recession in the upper mids, giving these a fairly U/V shaped sound signature - violins, for example, lack a bit of brightness/bite that I would hope for. But unlike other V-shaped IEMs, the mids aren't offensive. Incredibly fun to listen to. Probably the best single DD available. EQ highly recommended. Previously Owned

Excelllent bass - simply excellent. Midrange could use some work, as could the generally average imaging chops.

Best bass texture ever. Gorgeous treble extension, stage and imaging. Coherency and timbre a bit off. Upper mids/lower treble could be better. As amazing as it is, I couldn't fully connect with it (musically). Price is the biggest con.
