Nice note weight, very balanced, shockingly good at imaging held back by finicky fit and vacuum seal - fit issues can be resolved by changing tips though (for me the stock silicone LL tips eliminated fit issues for me but YMMV). At used prices today, it's a steal. Previously Owned

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.

Boring, but you won't find anything more well-rounded for the price. Exceptional timbre for a BA IEM.

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.
