Bone Conduction Technology

Why are these wireless appearances more suitable for outdoor sports?

❤ Unlike traditional headphones, they block the surrounding sound more or less, so you may be in danger when running or cycling.

❤ Bone conduction headphones work through vibration, and the sound is transmitted to your cochlea through the via bone. Compared with ordinary headphones, hearing damage can be avoided.

❤ The B9 wireless headphones are lightweight and will not fall off regardless of the type of strenuous exercise, allowing you to move freely. Proper method of wearing headphones: Hang the headphones behind the neck with the speakers on the jawbone in front of the ears, not on the ears,as the picture: B9 bone condition bluetooth headset.
