How do bone conduction headphones work? Features of bone conduction headphones

Junior high school physics teachers told us that sound can be transmitted through three media: liquid, gas, and solid;

The human body has two ways to transmit to the auditory nerve - air and bone.

Ordinary headphones transmit through air, while bone conduction headphones transmit to the auditory nerve through bones (skull).

Here I would like to share with you a "spokesperson" of bone conduction headphones in the 18th century - Beethoven

Everyone knows that the great musician Beethoven lost his hearing in his later years, but at that time Beethoven tried a technology invented by Giovanni (Beethoven bit a stick connected to the piano), and it was this technology that made him experience the beauty of music again.

Bone conduction headphones use the principle of bone conduction to transmit sound through the skull. There is no need to pass through the external auditory canal and eardrum. From this perspective, there is no damage to the eardrum. Because it will not harm hearing and block the ears, it will not bring negative pressure, blockage and discomfort to the ears; opening the ears can also effectively avoid ear canal and eardrum infection, and reduce the occurrence of various ear diseases (such as otitis media, eardrum inflammation, eardrum perforation, etc.).

Features of bone conduction headphones:

1. There are also great differences in wearing methods. Bone conduction headphones generally adopt ear hook and back hanging design. When wearing, the left and right vibration units are located near the temples, so the ears are completely open. It does not touch our ears at all, and only transmits sound through the vibration of the head bones. Therefore, there is no discomfort when wearing it for a long time, and it can also protect our eardrum.

2. The sound is directly transmitted into the nerves inside the ear through the skull, which minimizes the impact on the hearing of the ear. Many ear doctors also recommend bone conduction headphones.

3. Bone conduction headphones do not affect normal communication with others. Whether it is running, cycling, commuting, etc., wearing headphones to listen to music can still hear the surrounding sounds, and can also effectively avoid accidents caused by not being able to hear the outside world.

4. Bone conduction headphones are also very comfortable and hygienic, because bone conduction headphones are not in the ears, and will not cause the ear canal to be damp and deposit a large number of bacteria due to exercise or long-term earphone blockage. Moreover, it is generally fixed on the head, not easy to fall off, and will not cause ear pain due to long-term wearing, so it is very comfortable and hygienic.

Many people don’t know how to choose a good bone conduction headset, and the editor has stepped on many pits when using bone conduction before. Comtang bone conduction headset manufacturer introduces several real bone conduction on the market:

1. NANK Runner pro3 bone conduction headphones

Recommendation reason:

NANK bone conduction headphones have been recognized for their leading bone vibrator technology, both in terms of product quality and hearing protection.

In terms of configuration, NANK Runner Pro3 also has a built-in 16G body memory, supports IPX8 waterproof, and is equipped with Bluetooth 5.2. As the core technology of Bluetooth audio devices, Bluetooth 5.2 has greatly improved the functional experience of the product, with lower latency and stronger anti-interference ability, which can reduce 87% of Bluetooth disconnection. It is a bone conduction headset that truly achieves the ultimate in performance and function.

2. Shokz AS660 bone conduction headphones

Recommendation reason:

The overall appearance of the Shokz bone conduction headphones AS660 follows the classic design of the current bone conduction headphones. The titanium alloy material makes the entire headset light and burden-free. The AfterShokz logo, Type-C charging port and signal light are left on the sides of the hanging parts. In addition, the volume up button is combined with the power button, which makes reasonable use of the device design space and makes the overall body not appear too cumbersome. It also uses a new generation of Bluetooth 5.0 three-core chip to achieve a 1-second connection function.

3. Philips A6606 bone conduction headphones

Recommendation reason:

The surface of A6606 is made of skin-like material, which is closer to the skin when hung on the neck, and the wearing experience is greatly improved. It uses a 15mm sound unit, which has better sound effect, is more suitable for noisy environments, and the bass effect is also improved. The waterproof level of Philips A6606 reaches IP67 level, let alone rain, even direct washing is stress-free. Therefore, the cleaning method of A6606 is very simple and rough, just rinse it under the faucet.

4. Comtang E11W Bluetooth Stereo Bone Conduction Headphones

Recommendation reason:

This E11W Bluetooth Stereo Bone Conduction Headphones is a bone conduction headset, but its performance is still not to be underestimated. The headset body is fully enclosed, and the waterproof ability is greatly improved, reaching the IPX5 waterproof level, which can resist daily rain and sweat. Using the latest Bluetooth 5.3 technology, the connection is fast and the signal is stable. In terms of preventing sound leakage, Comtang E11W filters the external noise environment, realizes high-definition calls, and makes communication smoother.
