Bone Conduction

Aftershokz can’t say they invented bone conduction, but their technological enhancements certainly push its boundaries. Their patented open ear design guides mini vibrations through your cheekbones to your inner ears, delivering stereo sound without plugging or covering them. Sound waves travel directly to the cochlea, bypassing the eardrums completely—an alternative for anyone concerned about potential hearing damage caused by traditional headphones and ear buds, and even a solution for those with certain forms of hearing loss.


OpenFit makes it possible to experience ambient sound awareness without any limitations, through a design that offers extended comfort and a secure fit—vital for high-impact activities or long-term wear.


PremiumPitch is Aftershokz’s unique development in bone conduction headphones audio, where remarkably clean sound and discernible bass comes from patented dual suspension beryllium copper infused transducers.

Custom Equalization

Custom equalization adjustments take it a step further, allowing you to tune to preference at the touch of a button.


Though a range of sound leakage is common with almost all headphones and ear buds, most of us don’t want to share our music and conversations with others nearby. LeakSlayer technology significantly reduces natural sound leakage, effectively allowing you to keep sound to yourself.

Sweat Resistant

Nanotechnology-treated to repel sweat and other moisture, rest assured these Bluetooth stereo headphones will play on through your most rigorous sweat sessions.

Six Hours

Durably built to endure anyone-anywhere use, but also shockingly lightweight. Expect six hours of play per charge—and if you give them a boost the same time as your mobile device, you’ll never have to be without wireless stereo sound. Optional reflective stickers can be applied to increase visibility in darkness and an adjustable tension band assures a snug fit to any size head.

Audrey Says

Voice prompts that are meant to be more than a companion; these are designed to add ease to the user experience. With accessibility in mind, Audrey Says guides you through power, pairing and playing, and will even alert you when you’ll need a recharge.

Complete Controls

A multifunction button delivers complete control of music and calls right from the wireless headphone unit, which means your mobile device can remain safely tucked away during use.


Your wireless freedom doesn’t have to be plagued by traditional limits. Confidently stash your mobile device anywhere on your body—or even just somewhere nearby—without the inconvenience of signal drops and music skips.


Dual microphones in these stereo headphones deliver clear communication even in noisy environments.
