So are bone conduction headphones harmful to the body?
In fact, bone conduction headphones have no obvious harm to people. Bone conduction hearing aid and conventional airway hearing aid are both instruments used to enhance patients' hearing, but the enhanced conduction mode is different. Airway headphones, like normal auditory pathways, are all conducted by air through the ear canal, causing the vibration of the ossicular chain of the tympanic membrane and transmitting auditory signals to the inner ear.
Bone conduction headphones directly transmit auditory signals to the inner ear through the vibration of the temporal bone, causing hearing in the inner ear. Normal hearing includes bone conduction and air conduction. Of course, air conduction is the main thing at ordinary times. In some cases, if there is a problem with the airway, such as narrow and locked ear canal, there is no way to use airway headphones, and bone conduction headphones can be used instead.
At the same time, because the bone conduction exercise earphone does not need to be used by both ears, it also brings some health benefits. Because bone conduction headphones don't need to put earplugs in people's ears, they can keep the inside of the ear canal clean and hygienic. At the same time, the surface of the bone conduction earphone is smooth and easy to clean, while the traditional air conduction earphone is easy to deposit bacteria, so the bone conduction earphone is also very helpful to the health of the ear.
Secondly, because the clamping position of bone conduction headphones is mostly the hard bone position (beside the ear), rather than the direct obstruction of other headphones (such as in-ear headphones) and soft tissue support (such as clip-on headphones), the damage caused by wearing them for a long time is lower than that of conventional headphones (for example, if you wear them for four hours, the clip-on ears may not be able to stand it, but there is basically no feeling of bone conduction).
Moreover, the hearing loss of bone conduction headphones is smaller, because hearing loss generally occurs in the eardrum and inner ear, while bone conduction headphones directly bypass the eardrum. To prevent eardrum damage, the vibration wave of bone conduction earphone is mild, and the influence on hair cells will be small, so the bone conduction earphone has the least damage to hearing. For these reasons, many otologists also recommend this kind of earphone.
At present, there are not many brands with the core technology of bone conduction, and the mainstream bone conduction headphones are mainly Nanka and Shaoyin. Tell you some bone conduction headphones worth buying.
First, South Carolina runner pro3 bone conduction headphones
Recommended reason:
As the first headset brand in China, Nanka is also the first brand to put forward the concept of not listening to songs for different groups of people and achieve perfect integration. The most representative one is this Nanka Runner Pro3.
Sound quality optimization schemes, such as AF full-earthquake directivity technology and OT closed leakage reduction 3.0 technology independently developed, are all laid out in Runner Pro3 in South Carolina. The permeability of music and sound stage have been greatly improved, which can effectively reduce the phenomenon of missing sound, which is 90% less than the products on the market, making us listen to songs and speak more stably and have clearer sound quality. With a large bone conduction vibrator, under the professional tuning of Grammy audience, a deeper bass and a clear and natural tenor are customized, and the detailed analysis is also rich and delicate.
The wearing of headphones is ergonomically designed. South Carolina combined with the Asian ear database collected by users in the past and 97 engineers in South Carolina, after 197 days and nights of analysis and innovation polishing.
South Carolina Runner Pro3 is equipped with the latest Bluetooth 5.2 technology. Compared with the previous generation Bluetooth technology, the stability, effective distance and delay performance of voice connection have been greatly improved. In addition, it also supports NFC near-field pairing function. It is worth mentioning that South Carolina Runner Pro3 has built-in 16G storage, which can store about 3,000 songs, and its battery life has reached the highest 10 hour.
Second, as800 bone conduction headphones with less sound
Recommended reason:
Shaoyin AS800 has a good appearance, workmanship and face value. It adopts a bridge-crossing structure from the headband to the ear-sticking segment, which brings convenience to users wearing glasses. Compared with the previous generation of 600 and 650, Shaoyin AS800 upgraded the patented technologies such as PremiumPitch+ double suspension vibration transmission system and suspension shock absorption to 2.0. In appearance, the ear end was changed from square to long, the volume was reduced by 30%, the veneer area was increased, and the weight was reduced by 4g to 26g.
In the Bluetooth scheme, the AS800 also uses Bluetooth 5.0 chip, and this generation is also equipped with liquid residue detection function. When charging, if there is waterproof or other liquid residue in the charging port, the device will have a "red and blue light" flashing and give a warning sound, and there will be a voice prompt when the liquid dries. In waterproof aspect, IP67 is waterproof and sweat-proof, and the waterproof effect is very good. There is basically no need to worry about headphones being damaged by rain and sweat.
Third, South Carolina runners cc2 bone conduction headphones
Recommended reason:
Runner cc2 in South Carolina is quite competitive in bone conduction headphones with the same price because of its high cost performance. Earphones can be worn for a long time, without discomfort or pressure on users, which is very close to the non-inductive wearing pursued by users.
A new combination of Bluetooth 5.0+ ceramic antenna+signal enhancement is adopted, which makes the Bluetooth connection more stable. Food-grade skin-friendly silicone also makes the touch more comfortable. The waterproof performance has also been further improved, reaching the level of IPX6.
Four. Shanshui I 1S bone conduction bluetooth headset
Recommended reason:
This is an entry-level bone conduction earphone, which is cheap and worth starting with. The headset is equipped with 8G memory and has two playback modes. You can connect Bluetooth to listen to music or leave your mobile phone at home and play music independently through headphones. Qualcomm CSR Bluetooth chip with low power consumption is selected, which is made of titanium alloy and does not bend or deform. The fuselage weighs only 30g, which is waterproof and can easily cope with the infiltration of daily rain and sweat.
V. Yiou Heping TW- 1 Bone Conduction Headphones
Recommended reason:
Yiou earsopen PEACE TW- 1 Headphones can be charged magnetically through the charging bin, which is small in size and easy to carry around. Its earphone design and modeling adopt the separated design first realized in the bone conduction industry. The earphone body is T-shaped, and the ear clip is worn. At the same time, it also supports IPX7 waterproof performance. Burning fat when traveling or running in rainy days, you don't have to be afraid of the erosion of sweat and rain, so you can use it with peace of mind.
The T-shaped structure design of earsopen PEACE TW- 1 adopts the form of wearing behind the ear with an arc support frame, which is more comfortable to wear and can effectively improve the wearing comfort. However, due to the way of wearing, the auricle will feel uncomfortable after wearing for a long time. The sound quality is average and the sound leakage is a little big, but as an innovative style in bone conduction, it is also worth considering.
