I'll go (oh wait someone commented first!) second. Got BLON BL-03 in late 2020s, my first ever IEMs. Loved them to death. However, halfway there, the Left guy split into two shells. Glued and soldered them till they gave out. Lasted approx. a whole year.

ER2XRs. Heard great things about them!. How long has it been since you have had them?
