9 DIGITAL Bone Conduction Headphones Lite User Manual

Introduction

Thank you for choosing the 9 DIGITAL Bone Conduction Headphones Lite. These open-ear headphones utilize patented bone conduction technology to deliver audio through your cheekbones, allowing you to remain aware of your surroundings while enjoying sound. Designed for comfort and durability, they are ideal for various activities including running, cycling, hiking, and gym workouts.

Bone conduction technology transmits sound vibrations directly to the inner ear via the cheekbones, bypassing the eardrum. This method allows for an open-ear listening experience, enhancing safety during outdoor activities by keeping your ears open to ambient sounds.
