Budget

The Moondrop CHU is an OK $20 earphone that is overrepresented and overrated by the internet’s echo chamber, which distorts the playing field.

Moondrop CHU are very good for their price, although they don’t do better than the established price bracket leaders in my views.

A warm-neutral sounding, technically capable iem with an over-energized midrange and a weak bass that shoots the whole sonic impression out of shape.

Good tuning meets average technicalities…

The IKKO OH2 is a warm and dry sounding single dynamic-driver iem with great timbre and good articulation with an overly safe tuning in the upper registers.

Pros — Cohesive sound of surprising quality; clean notes; excellent tuning; metal build, decent accessories. Cons — Stock tips too

Note: this earphone was first released as KZ ZEX, later as KZ x CRN ZEX. They are all the same
