Easy to Wear, Unlikely to Fall Off
The NJ310B have been designed to be easy-to-wear and unlikely to fall off. An ergonomic, double-hold shape newly developed for the earpiece firmly sits in two places, the tragus and anti-tragus, for earbuds that fit your ear perfectly. Furthermore, the remote control and battery case have been symmetrically arranged for a stable fit that makes them unlikely to fall off
