Bone Conduction Glasses, Open-Ear Headphones Bluetooth, Photochromic Sunglasses Anti Blue Ray, IP6 Waterproof Audio Glasses, Hand-Free Calling and Music, Smart Glasses for Women and Men

All kinds of bone conduction headphones in the market transmit sound through vibrating bones. When the headphones are working, the outer shell of the earphone will be vibrated with the sounding vibrator inside. Then the outer shell vibrates the surrounding air, which may lead to sound leakage specially when the volume is at max. For best listening experience or when in quiet places, we recommend that customers can adjust the volume at 50%-60% of their bluetooth devices like cell phone, sound of smart glasses will NOT be noticeable by people aound 1-2 meters away. When in noisy environment, you can use the earplugs to cover your ears, so that you will hear the sound from glasses more clearly.
