The earphone is closer to the inner ear tissue than the general external noise; Users have to take necessary protective measures. Studies have shown that pleasant music causes less hearing damage, but long-term exposure to high-decibel sounds, whether music or noise, will cause hearing damage. Sensory nerve hearing damage caused by noise occurs in the inner ear. When high-energy sound waves shock the fluid in the cochlea, it will be overstimulated and cause cell death. Hearing impairment is formed over time. If you are exposed to noise for a long time, even if the time is short, it will also cause hearing loss. The results of a survey published in Journal of American Medical Association in 1998 and the experiment of Shanxi Medical University in China show that long-term exposure to high noise level has a negative impact on hearing. When using headphones in the street, apart from hearing damage caused by increasing the volume, it is easy for users to lose their alertness to external sounds and increase the chances of danger, so it is not suitable for children to use them. Bone conduction headphones can avoid the above problems well because of their open ears.

Take AfterShokz Shaoyin as an example. Unlike most earphones that block both ears, Shaoyin headphones use bone conduction technology to transmit sound directly to the inner ear through the skull, thus bypassing the eardrum and being more healthy and comfortable. At the same time, it is safer to monitor the surrounding environment while using headphones while exercising and driving. Due to the technical iteration, the new product of Shaoyin, Aeropex bone conduction Bluetooth headset, has reduced the vibration and made the low frequency more delicate. 26g ultra-light weight, IP67 waterproof and sweat-proof, 8-hour battery life, suitable for sports, driving, daily life and other scenes. AfterShokz Shaoyin headphones are also the headphones of IAAF and USA Triathlon, which set a new industry standard for sports headphones.
