AfterShokz Sportz M2 headphones sit comfortably in front of (not inside or over) your ears, delivering the only open ear listening experience that doesn't inhibit ambient noise. They use bone conduction technology to transfer stereophonic sound via little vibrations on your cheekbones to your inner ears, bypassing the eardrums completely.
The open ear design enables you to listen to music and taking phone calls when you're running, biking, jogging, driving, hiking, skiing and more all while safely staying connected to your surroundings. The unique benefit of our open ear design offers situational awareness, potentially preventing accidents that can be caused by traditional headphones and earbuds blocking outside sounds.
