Releasing status?
I guess Moondrop is advancing toward new hot zone $450-550. The EST hot spots with Thieaudio brothers Oracle/Excalibur, DUNU EST112, TRI Starshine, and many other smaller boutique shops. Also KZ seemed is marching toward first affordable EST project too.
I personally found Dusk is one of best tuned IEM around, and really longed for EST and LCP to coup the only weakness of Dusk, “treble response/smoothness/extension & better resonance and transients /textures on bass ~ sub-bass.”. It seems treble concern is gone. So Blessing(shell) EST project may become “B-EST” one to choose for $450-550 EST hot zone! Since B2 is 1999CNY, and seeing other competitors, 2888CNY =449USD & 2999CNY =466USD sounds like a plan(wink*
wink*). I know Chinese love number 888.
For headfiers, here are some interesting datasheet of Sonion’s EST driver, which most likely will be packaged with Blessing-EST, just to share the basic measurements and specs:
