Can bone conduction headphones cause harm to hearing or other aspects?

Real bone conduction headphones will only protect hearing and will not cause any harm. The structure of human ear consists of external auditory canal, tympanic membrane, ossicles, cochlea and auditory nerve from outside to inside. Under normal circumstances, no matter ordinary wired headphones, Bluetooth headphones and noise-reducing headphones, they all belong to "air-guiding headphones" in essence, that is, the air in the external auditory canal is the main sound transmission medium, and only a small part of sound waves propagate through bones. In the process of air conduction, the micro-speaker of the earphone vibrates, and through the air in the external auditory canal, the sound waves are transmitted to the tympanic membrane, the ossicles, the labyrinth of the inner ear and other parts in turn. The vibration of lymph inside and outside the inner ear helps the spiral organ to perceive sound. After reaching the auditory nerve, the auditory nerve generates nerve impulses and sends signals to the auditory pathway. After a comprehensive analysis of the cerebral cortex, we can "hear" the sound. Note: the ossicular bone is the smallest bone in the human body, with three pieces in each ear. The ossicular bone is composed of malleus, incus and stapes, most of which are located in the superior tympanum and connected by ligaments and joints to form the ossicular chain.

The most unique feature of bone conduction headphones is that sound waves do not pass through the air in the external auditory canal and tympanic membrane, but directly use the human bone structure as the sound transmission medium. When in use, the sound source of the bone conduction earphone should be pressed on the skull behind the ear. When the sound source vibrates, it will drive the skull to vibrate together, so that sound waves can be introduced into the skull. Then, the sound waves pass through the skull, bypass the external auditory canal and tympanic membrane, and directly reach the ossicles. Then the ossicles introduce sound waves into the labyrinth so that sound information can be transmitted to the cochlea and auditory nerve. In this way, we successfully used bone conduction technology to hear the sound.

Bone conduction is carried out by moving and squeezing. Sound waves radiate to the ear through the cerebral cortex and bones, stimulating the spiral device in the ear to cause hearing. There is no need to vibrate the eardrum like a horn to transmit sound, and the timbre is very clear. People with damaged eardrums can use all kinds of audio equipment normally, and people with normal hearing can effectively protect their hearing. The unique bone conduction earphone has a sound pressure of only 60 dB. Even if it is used at high volume for a long time, the ear will not be hot, painless or painless.

At present, the field of bone conduction headphones has good quality and the highest cost performance. At present, the most representative concave-convex earphone wdj-v6plus is at the leading level in all aspects. Concave-convex wdj-v6plus bone conduction earphone is the star product in bone conduction earphone at present. In less than a few months on the line, not only the sales volume rose rapidly, but also the cumulative reputation of users was as high as 98%. On major platforms (Tik Tok, Little Red Book, etc. ), I often see the star network red wearing the same paragraph.

Otum has been in the field of earphone acoustics for 10 years, and its research and development strength is strong, which can be described as grinding a sword in ten years. The configuration, sound quality, comfort, design and endurance of concave-convex bone conduction headphones are among the best in sports headphones. This cost-effective sports headset uses innovative bone conduction black technology to listen to high-quality music without listening. Equipped with Bluetooth 5.0 chip scheme, dual microphone channels, 32G large memory card that can store 6000+ music, and the body design with no holes and no sound leakage. With OT closed sound reduction technology 2.0 black technology, the sound reduction phenomenon is reduced by 90%, the fuselage is only 30 grams, listening to songs for 6 hours, and the fully closed technology can make it stable and travel lightly.
