What is the harm of bone conduction headphones and Do They Have health risk on the Human Body?

Dec 13,2022 | Sylvia

Regarding the harm of bone conduction headphones, many statements are not accurate. In fact, as long as it is used normally, they are not harmful to the human body. To understand this problem, firstly you have to briefly understand the sounding principle of them. The headphones we use every day, whether they are head-mounted, in-ear, or wireless Bluetooth headphones, mainly transmit sound waves to the ears through air conduction. During this process, many noises and noises from the outside world will also be transmitted to the auditory nerve.

Bone conduction headphones are different from common headphones in that they do not require air conduction, but are transmitted through the skull to the auditory center. There is almost no noise during this transmission process, so the sound is much clearer than air conduction. It can be heard even at low volumes. Plus, they're quite different in how they're worn. They generally adopt ear-hook and rear-hook designs. When wearing it, the left and right vibration units are located near the temples, and your ears are completely uncovered. If you can't use airway headphones for your own reasons, you can use bone conduction headphones instead.

Bone conduction headphones are not only harmless to the human body, but also a kind of headphones that cause the least damage to the ear hearing. Because their sound transmission method uses human bones as the medium, the transmitted sound will become very moderate, and some harsh electronic sounds are filtered out, which makes the sound reproduction more realistic. Although this way of listening to music cannot give the sense of immersion of in-ear headphones, it is undoubtedly the healthiest way of listening to music, which is why many professional ear doctors have repeatedly recommended bone conduction headphones.

At the same time, because of the unique sounding principle, bone conduction headphones can listen to music without wearing them in the ear, which can effectively avoid various ear diseases caused by in-ear headphones, so they have been recommended by otologists and hearing experts. For some people with otitis or sensitivity, they will also be a good choice. At the same time, they also have significant safety, which is very suitable for people who love outdoor sports and fitness. Because using bone conduction to listen to songs, you can still hear the surrounding sounds. When riding or even driving, you don't have to worry about wearing headphones to block the surrounding sound and cause danger.

At present, in the bone conduction headphone market, there are not many brands with professional bone vibrator technology. It is understood that the two brands of Wissonly and Aftershokz are relatively good, and they belong to the first echelon in terms of technology; the sound quality, sound leakage prevention and wearing comfort are all well done, but the price is relatively expensive. These two brands have been researching on bone conduction technology for more than 10 years, with profound technology accumulation and relatively mature technology. Some brands do not have their own bone conduction technology research and development team or the brand has just started and has not yet completed technology research and development, so the tuning conditions and tuning technology are relatively lacking. Therefore, the experience of this kind of bone conduction headphones is relatively general, and the price is relatively cheap. Next, I will talk about some headphones that are worth buying.

1. Wissonly Hi runner bone conduction headphones

Reason for recommendation: The most comprehensive and easy-to-use bone conduction headphones I have experienced.

Wissonly is a brand known for its technology, and it is also the fastest-growing brand in recent times. Their R&D team is all technical experts in the field of bone conduction headphones. As early as 2012, they began to develop bone conduction headphones that do not hurt the ears. With their advanced bone conduction vibration technology, they have been recommended by many doctors.

What impressed me the most was the excellent sound quality of the Wissonly Hi Runner. They are equipped with a large-sized directional bone conduction vibration unit, and the effective sound-emitting area has been increased by 35% through structural optimization, so that the sound range is wider, and the sound is more three-dimensional and shocking. At the same time, they also improved the problem of sound quality loss caused by the low sound transmission efficiency of traditional bone conduction headphones. They worked with world-class tuners in the world's top tuning laboratories to customize an exclusive sound quality output solution for Hi Runner bone conduction headphones.After more than 20 tuners adjusted 85036 times, the sound quality really belongs to bone conduction was finally presented.

The body of Wissonly Hi Runner is made of memory titanium material, which can self-adjust the contact area, so it can ensure that the wearer has a good wearing experience and take into account more users.

As the core component of the product, the headphone chip plays a key role in the product experience. Hi Runner is equipped with a Bluetooth 5.0 chip, which makes the Bluetooth connection very stable. It also has a built-in memory of 32G, and it also supports IPX8 waterproof, even diving can be used.

2. AfterShokz Openrun Pro bone conduction headphones

Recommended reason: Under the old brand of bone conduction headphones, it is a relatively mature bone conduction headphone.

AfterShokz Openrun Pro headphones are very light, only 26g. They are very light and comfortable when you wear them on your ears for running. They are made of titanium alloy, and the headphones on both sides are wrapped in skin-friendly silicone material. At the same time, they also have IP67 waterproof, so they can be rained, splashed, and washed. Even if you encounter bad weather during outdoor sports, there will be no problem. The structure of the headset adopts a rear-hanging design and is not worn in the ear, which is very friendly to users who often wear it. They're also paired with a Bluetooth 5.0 triple-core chip, which allows for fast connections. They can connect with stable sound quality within 10 meters, and can also be intelligently identified by algorithms to effectively filter environmental sounds and make human voices clearer.

3. HIFIMAN GR8 Bone Conduction Bluetooth Headphones

Recommended reason: A good entry-level bone conduction headset, a good choice for people with low budget

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

When wearing this headset, even if you sweat during exercise or encounter rainy days, you don't have to worry about it. The manufacturer has endowed these headphones with IPX4 level waterproof ability, even if they encounter some sweat and rain in the daily use environment, basically there is no big problem, which can be regarded as expanding its applicable scenarios to a certain extent. Although their sound quality is so-so, they are already considered good at this price, and they are worth choosing among entry-level models.

4. FMJ B2 Bone Conduction Headphones

Recommended reason: entry-level bone conduction headphones

This bone conduction headset uses Bluetooth 5.0 wireless connection and has a built-in 8GB local storage space. They use bone conduction to produce sound, and have a life waterproof rating of IP55, which is slightly insufficient for aggressive sweat. In addition, its battery can last for 8 hours with low power consumption. As for sound leakage and vibration, this model does have problems in this regard. But a coin has 2 sides, it's such a low price you can hardly ask for more.
