As per web info:
With a revolutionary design, the Aftershokz Trekz Air Headphones are one of the safest sets of headphones on the market. Unlike standard headphones which cover your ears and block out all other sound completely, the Aftershokz conduct sound vibrations through the bone structure, so that you remain fully aware of your surroundings. Despite this design, audio quality isn’t sacrificed, and the headphones still deliver a quality sound and a rich, thick bass. While the complete wrap-around design offers lasting rider comfort and stability, thanks to the titanium frame, the Aftershokz Trekz Air is also one of the lightest models in the range.

With full wireless Bluetooth compatibility, the Aftershokz can pair with a wide variety of devices such as phones, MP3 players and even allow you to take calls, using the dual noise-cancelling microphones. All this technology is protected by a highly durable casing that repels sweat, dirt and moisture, so you can use your Aftershokz during intense workouts and the worst weather conditions.
