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.

Lot of fun IEM. Is it perfect? No. Treble could use a little work. Harmanish take on low end with relaxed top end.

S- Tech
Bright leaning set with great tech. Clean mid-range, sharp imaging, sparkly female vocals with decent amount of air. Does get fatiguing and sharp on more energetic tracks and genres like EDM/POP/KPOP/JPOP, aka lower to mid volume set. Sounds very good on slower genres like indie, acoustics, ballads - adds more energy and liveliness to the slower nature of those genres. Mid-bass is lacking and would not recommend for rock or hiphop.

Bit lacking in engagement, bass typical of BA drivers.
