Is bone conduction earphone harmful to human body?

In fact, as long as it is used normally, bone conduction headphones are harmless to the human body. Let's briefly talk about the sound principle of bone conduction headphones. In our daily use of headphones, whether headphones, in-ear headphones or wireless Bluetooth headphones, sound waves are mainly transmitted to the ears through air conduction. In this process, a lot of external noise and murmur will also be transmitted to the auditory nerve.

Bone conduction headphones are different. They don't need air conduction, but reach the auditory pathway through the skull. There is almost no noise and murmur during transmission, so the sound is much clearer than air transmission, and even a small volume can be heard. In addition, there are also great differences in the way of wearing. Bone conduction headphones generally adopt ear hook and rear hook design. When wearing, the left and right vibration units are located near the temples, and the ears are completely open. If you can't use airway headphones, you can use bone conduction headphones instead.

Bone conduction earphone is not only harmless to human body, but also a kind of earphone with the least damage to ear hearing. Because the transmission mode of bone conduction headphones is based on human bones, the transmitted sound will become very gentle, and some harsh electronic sounds will be filtered out, so the sound reproduction will be more real. Although this way of listening to songs can't give people a sense of immersion, it is undoubtedly the healthiest way to listen to songs. The famous medical website "clove doctor" has recommended bone conduction headphones many times.

At the same time, bone conduction headphones can listen to songs without wearing them in the ear, which can effectively avoid various ear diseases caused by in-ear headphones. They have been recommended by otologists and audiologists. For some patients with otitis media or sensitive people, bone conduction headphones will also be a good choice. It is also very suitable for friends who love outdoor sports and fitness. Listening to songs through bone conduction can still hear the surrounding sounds, and there is no need to worry that wearing headphones will block the surrounding sounds and cause danger.

At present, only two first-line brands, Nanka and Shaoyin, have professional bone vibrator technology in the bone conduction earphone market. Sound quality, sound leakage and wearing comfort are good, but the price is more expensive. These two brands have studied bone conduction technology for more than 10 years, and each has hundreds of patented technologies. At present, the technology is relatively mature. Many second-tier brands and some unknown brands don't have their own research and development team of bone conduction technology, or the brands have just started to complete technology research and development; Generally, male models are used, and there is no tuning technology. This kind of bone conduction experience is relatively general and the price is relatively cheap. Let me talk about some bone conduction headphones worth starting with.

First, South Carolina runner pro3 bone conduction headphones

Highlight: The bone conduction earphone I have experienced is the most comprehensive and best to use, and it is the best recommendation.

Although its brand awareness is not high, it is a behind-the-scenes technical hero in the field of bone conduction headphones. As early as 20 12, we began to develop bone conduction headphones that don't hurt our ears. With the original full vibration directivity technology, it has gained a reputation in the field of bone conduction and has been recommended by the majority of otologists! It has also passed the effective certification of the clove doctor team.

Pro3, a South Carolina runner, took the lead in carrying AF directional vibrator acoustically, which improved the problem of sound quality loss caused by the low sound transmission efficiency of traditional bone conduction headphones. At the same time, South Carolina also invited Grammy listeners to customize the exclusive sound quality output scheme to realize unique bone conduction sound transmission. Twenty-three audiologists adjusted 105063 times day and night, and they have stereo cranial cavity sound quality, showing good sound quality that really belongs to bone conduction.

South Carolina Runner Pro is made of memory titanium, and the contact area can be adjusted by itself to ensure a good wearing experience of headphones at any time, taking into account more users.

As the core component of the product, the earphone chip plays a key role in the product experience. Runner Pro3 is equipped with Bluetooth 5.2 chip, which fully optimizes the basic product experience, and also adds NFC quick pairing and one-drag-two functions to make the operation more portable.

Second, as800 bone conduction headphones with less sound

Highlight: Bone conduction earphone, a mature bone conduction earphone under the old brand.

As800 headphones are very light, only 26g, so they are very light and comfortable to run on your ears. The whole machine is made of titanium alloy, and the earphones on both sides are wrapped in skin-friendly silicone material, and the LOGO of Aeropex with little sound is printed on both sides. IP67 is waterproof and dustproof, and can be showered, splashed and cleaned. Even if outdoor sports encounter bad weather, you are not afraid at all, so that you can enjoy sports to the fullest. In terms of structure, it adopts the rear hanging design and is not worn in the ear, which is very friendly to users who wear it frequently. The whole machine is also equipped with Bluetooth 5.0 three-core chip, which can realize fast connection and stable sound quality connection within the range of 10 meter. It will also be intelligently recognized by the algorithm, effectively filtering the ambient sound and making the human voice clearer.

Third, HIFIMAN GR8 bone conduction Bluetooth headset

Highlight: You can consider a good entry-level bone conduction earphone with low budget.

HIFIMAN bone conduction Bluetooth headset GR8 directly uses titanium alloy skeleton design of memory. Even if we twist at will, the earphone structure can be restored instantly when the force is removed. The biggest advantage of this design is that it can basically guarantee the same wearing experience every time.

Sweating or raining will inevitably affect the use of strenuous exercise. However, the manufacturer has given this earphone IPX4 waterproof ability, and some sweat and rain we encounter in our daily use environment are basically not too big problems, which can be regarded as expanding its application scenarios to some extent. Although the sound quality is average, this price is still good, and it is worth choosing among entry-level models.

Four, South Carolina runners cc2 bone conduction headphones

Highlight: The only mature bone conduction earphone in 300 yuan.

Since the advent of Runner cc2, the sales situation has been excellent. Because of its strong performance and high cost performance of only 299, running man CC2 has no rival in the entry-level bone conduction earphone market.

A new combination of Bluetooth 5.0+ ceramic antenna+signal enhancement is adopted, which makes the Bluetooth connection more stable.

Runner CC 2' s skeleton is made of aviation grade material, which is stronger and lighter. Runner CC 2 in South Carolina is 7g lighter than the previous generation of 35g, only 28g. Food-grade skin-friendly silicone also makes the touch more comfortable. The waterproof performance has also been further improved, reaching the level of IPX6.

Five, FMJ B2 bone conduction headphones

Highlight: affordable and balanced entry-level bone conduction headphones.

This model adopts Bluetooth 5.0 wireless connection mode and has built-in 8GB local storage space. It adopts bone conduction sound mode. The protection level is only lifelong waterproof, which is slightly insufficient for aggressive sweat. 8 hours battery life, low power consumption. As for sound leakage and vibration, different people have different opinions. After all, there is nothing to be picky about this price, and the material is memory alloy, which is not easy to damage.
