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

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

Neutral tonality, highly coherent and decent detail pickup. The all-rounder of the IER lineup.
