How Do Bone Conduction Headphones Work?

Bone conduction headphones work by sending sound waves through the bones of the skull, rather than through the air like traditional headphones. When the vibrations pass through the bones of the skull, they reach the inner ear and are interpreted by the brain as sound.

Bone conduction headphones have a small transducer that sits on the bone behind the ear and sends the vibrations through the bone. The transducer is usually held in place with a flexible headband or earhooks. Some bone conduction headphones also have traditional speakers that sit outside the ear and produce sound waves through the air, but the primary source of sound is still the bone conduction transducer.

This allows the wearer to hear the audio without blocking out external sounds, making bone conduction headphones a good choice for people who need to be aware of their surroundings, such as joggers or bicyclists.

The Runner Pro features an open-ear design with an 8-hour playback time and a battery capacity of 230mAh. They utilise magnetic fast charging technology, which means they can be fully charged in 1.5 hours.

Naenka Runner Pro are IPx8 waterproof certified, and completely resistant to sweat, moisture and dust making them ideal for any indoor or outdoor sport, including swimming, snorkeling, and surfing.

They utilise Bluetooth 5.0 connectivity and provide convenient multi-point pairing, compatible with your iOS and Android Bluetooth devices. They feature both Bluetooth mode and MP3 mode and an on-board 8GB memory to store music on.

They come with an adjustment band meaning they will fit any user and can be tightened to suit any level of movement (or non movement). Even without this feature they are a comfortable sturdy fit. The Naenka Runner Pro headphones are a top-of-the-line option for athletes and fitness enthusiasts.

The Runner Pro fit is comfortable and secure with very little movement. I feel like this level of comfort is a step up from the Runner Caller model.

The bone conduction aspect makes these headphones particularly suited for roles that involve customer interactions, such as receptionists or warehouse work, with a focus on safety. The strength and versatility here resides in the waterproof aspect.

They also come with a variety of features that cater to athletes. The built-in microphone allows for easy hands-free calling, and the controls are conveniently located on the side of the headphone for easy access.

For me a major concern was the latency (a millisecond or so) between the source and the Runner Pros. This is only really an issue for watching videos whereas the latency for music is not noticeable.

Overall, the Naenka Runner Pro headphones are an excellent choice for athletes and fitness enthusiasts who are looking for a high-quality bone conduction headphone. The design, sound quality, and features cater to the needs of active users, making it a worthwhile investment for anyone who wants to stay connected and motivated during their workouts.

You can pick up the Naenka Runner Pro from their website and all good stockists for around £99 GBP
