Haven't saw any reports online, so here it is
Guess my luck finally ran out, even though I had a few IEMs with widespread QC issues (Chu, Salnotes Zero, Final E500), this is my first "win"
Other than the faceplate issue, I like the sound (can't justify spending this much since I own an EM6L), hopefully the Chopin lasts long
I had the same issue with my Moondrop Variations. The faceplat of the left speaker fell off and a part of the housing got damaged without the plate.
