2. Wearing the Earphones
The Moondrop CHU earphones are designed to be worn with the cable routed over the ear. This method provides a secure fit and reduces microphonics (cable noise). Identify the left (L) and right (R) earpieces, typically marked on the housing. Gently insert each earbud into the corresponding ear canal and loop the cable over your ear.
