Recently, on the social platform, some netizens complained that wearing bone conduction earphones made them dizzy and headache. Are these symptoms caused by bone conduction headphones? Are bone conduction headphones suitable for everyone? Let's learn together. The reporter saw in the comment sections of various social media platforms that multiple netizens have successively exposed discomfort symptoms such as walking imbalance, dizziness, nausea, and tinnitus due to wearing bone conduction headphones. This type of discomfort is not an isolated case, and feedback has been spreading from user reviews on e-commerce platforms to discussion posts on social media platforms. On a certain social media platform, a netizen posted: "Swimming is so boring, I bought bone conduction headphones, but once I wear them, I get a headache. The reporter noticed that the netizen's experience quickly resonated, and a large number of netizens in the comment section expressed the existence of similar experiences. Many comments below also indicate that 'wearing it at work doesn't make much noise, but wearing it makes me feel a bit dizzy and headache'. Some netizens have expressed that they have developed otolith syndrome after wearing it for a month. Some users also reported that initially they attributed their symptoms to their own reasons or sleep problems, until they "stopped using the headphones and the symptoms improved" before locking the trigger on the bone conduction headphones. The reporter found through searching on e-commerce platforms that there are hundreds of products related to bone conduction headphones on sale, with prices ranging from hundreds to thousands of yuan. In response to feedback from netizens about dizziness, imbalance, and other discomfort during use, the reporter randomly consulted multiple bone conduction headphone stores. The interviewed customer service representatives all responded that everyone has different experiences. Which groups of people are not suitable to wear bone conduction headphones? How can sound be transmitted through bone conduction? Who experiences dizziness and imbalance when using bone conduction headphones? Does bone conduction headphones really not affect hearing? According to relevant experts, normal headphones transmit sound through the air, and the auricle collects sound waves, causing the eardrum to vibrate from the external auditory canal. The vibrations are amplified through the ossicular chain (malleus, incus, stapes), and the activity of the stapes floor causes the inner ear cochlear lymphatic fluid to vibrate through the vestibular window. Hair cells perceive and convert the signals into nerve signals, which are then transmitted to the auditory center of the brain through the auditory nerve, ultimately forming hearing. And bone conduction headphones are "bone conduction sound". The vibration unit of bone conduction headphones transmits sound waves directly to the hair cells of the inner ear cochlea through the vibration of the skull, bypassing the outer and middle ears, allowing people to perceive sound. Kong Ying, chief technician of the Department of Neurology and Otology at Beijing Tongren Hospital affiliated to Capital Medical University: As bone conduction headphones transmit sound through the vibration of the skull, if the skull vibrates for a long time, especially at low frequencies, the vibration response will be greater, which can easily affect vestibular function. So some people may experience a series of vestibular symptoms such as dizziness after wearing bone conduction headphones for a long time. Additionally, there are some promotional materials that may mislead people, claiming that using bone conduction headphones can protect hearing but will not affect it. However, in reality, whether it is air guided headphones or bone guided headphones, the final sound must be transmitted to the hair cells in the inner ear. If headphones are used improperly, they can affect the function of inner ear hair cells, thereby affecting hearing. People who are not recommended to wear bone conduction headphones include: 1. Those with abnormal skull/temporal bone: those with poor healing of skull fractures, temporal bone deformities, or severe osteoporosis, whose vibration transmission is obstructed, not only resulting in poor sound quality, but also possibly exacerbating bone discomfort due to certain pressure. 2. For those with chronic pain or injury to the head, such as migraine, temporomandibular joint disorder, or unhealed head trauma, headphone vibration can stimulate the affected area, exacerbate pain, or affect recovery. 3. People who are sensitive or have low tolerance to vibration: Some people may experience obvious skull vibration when wearing it, leading to discomfort such as dizziness and nausea. This group of people is not suitable for long-term use. Kong Ying also introduced that whether using air guided headphones or bone guided headphones, it is recommended to wear and use them scientifically and safely. Remember the "Three 60 Principles". Firstly, when using headphones, the volume should not exceed 60% of the maximum volume of the headphones. The second is to use the headphones continuously for no more than 60 minutes. Thirdly, try to use headphones in places where the background noise is less than 60 decibels, that is to say, try to use headphones in a quiet environment. (New Society)
