Aftershokz Sportz 3 AS400 Wired Bone Conduction Headphone
The Aftershokz Sportz 3 uses bone conduction technology to transmit sound to your inner ears, bypassing your eardrums. Listen to music and podcasts from any device with a 3.5mm jack.
The headphone band wraps around the back of the head, while the transducers rest on the cheekbones in front of your ears, so it stays secure while going about your daily activities. Stereo sound is transmitted through vibrations to your inner ears, bypassing your eardrums. Comfortable and lightweight to wear, the headphones do not cover your ears so you can still hear the sounds around you.
