The 1MORE Passive Penta Drivers Headphones focus on two things: the user and music. By providing solutions to ergonomics, sound quality, and usage. 1MORE have designed this earphone with a removable earplug, ear-hook, and have made all surfaces that touch the skin from medical-grade rubber to ensure comfort and stability. Furthermore, the earphone shape is based on ear ergonomics. It fills the entire ear cavity to provide excellent sound isolation. Adapting to changing user behavior, 1MORE decided to make this high-end earphone neckband style with a soft rubber band and larger battery compartment. It is comfortable to wear all day.
