Bone conduction is the transmission of sound vibrations to the inner ear (cochlea) bones of the skull, which allows you to perceive sound without blocking the ear canal. Even more simply put: it’s sound that is delivered directly to the inner ear without needing to pass through the eardrum. Think of bone conduction as a shortcut to hearing sound.

Have you ever plugged your ears and sang a song, but wondered how you can still hear the tune? Or heard the sounds generated from brushing your teeth or eating potato chips? That’s bone conduction at its finest, and, along with more commonly used air conduction, your ears have been transmitting sound that way all along!


Unlike traditional in-ear or on-ear headphones that utilize air conduction, Bone conduction headphone has mastered the natural phenomenon of bone conduction by adapting it to consumer electronics, and it’s now the secret behind the success of our open-ear product line. Here’s how we’ve harnessed bone conduction technology to work for our products:

1. Audio Enters The Transducer

Every Cheeroll audio device features two transducers on either side. These transducers, positioned near the cheekbone, work to convert audio signals into mechanical energy (vibrations) which is then sent to your cheekbones.

2. Titanium Makes Conduction Seamless

The use of titanium in the frame of all Cheeroll products is not only because of its lightweight and flexible properties, but also because titanium is an ideal metal for properly and efficiently conducting sound waves.

3. Vibrations Are Converted Into Audible Sound

Advances in bone conduction technology have enabled us to create devices that minimize the sensation of vibrations on the temple while still retaining high-quality sound.

The Difference Between Bone
Conduction Open-Ear Headphones and
Air Conduction Open-Ear Headphones:

Bone Conduction Open-Ear

The popularity of open-ear headphones has proved the importance of environmental awareness for consumers, and Cheeroll bone conduction headphones allow for the most natural open-ear listening experience with minimal sound leakage, don’t fatigue the outer or middle ear, and stay put through any activity. By nature, it’s hard for bone conduction to outperform air conduction in terms of bass, but Shokz have been praised by experts worldwide for their overall audio quality, specifically with Aeropex, featuring 8th generation bone conduction technology for a deeper bass, crystal-clear midrange and crisp highfrequency performance, while also being ultra-lightweight and ergonomically designed for a comfortable, snug fit.

Air Conduction Open-Ear

Open-ear headphones powered by air conduction work a little differently. With this design, two holes are added on the earbud; one hole, located close to the ear, transmits sound through the air to the ear. The other hole, located on the opposite side of the earbud, reduces sound leakage using anti-phase sound. While this open-ear design delivers some situational awareness, it requires a louder volume to ensure sound clarity (therefore drowning out ambient noise) and a larger battery capacity, which causes an increase in the weight of the earbuds or headphones. This combined with their loose fit could cause the earbuds to move and shift during high-impact activities.



One of the most loved features of Mionble headphones is that there are no irritating, sweaty earbuds jammed into your ear due to our open-ear design. Cheeroll are also easy to clean; simply wipe them down with a soft, dry cloth after a hard workout.


Safety first! While other headphones and earbuds block the ear canal to offer a noise-canceling experience, Cheeroll open-ear products keep you aware of your surroundings and possible hazards, such as traffic, wildlife, and pedestrians, for a safer listening experience.


Stay connected to your running buddies, coworkers, family, or environment. As opposed to traditional headphones that only allow you to hear your music and block out the sound of conversations and ambient noise, Cheeroll allows you to enjoy your audio and the world around you, so you never miss a moment.
