Removing the mesh from the iem housing of the ESX improves the clarity.Newer KZ IEM specially the DD releases doesn't have that metallic treble anymore and boxy sound. So far out of the newer KZs I have, EDA Trio, CRA+, EDX Ultra, ESX..ESX is the safest tuned and has the most likeable signature, the bass may be too much in some tracks, but you just need a widebore tips like Kbear07 to counter that. Imho, all KZ iem should include a tips that is somehow similar to Kbear07 or just straight up widebore tips, the KZ starline/stock tips degrades the overall sound quality in my experience.
It is glued, so the trial is possible without any damage.
