When the mighty Marines are training or performing tasks, in addition to the necessary individual equipment, they will wear a communication device on the pinna, which is a professional-grade military bone conduction headphones. This equipment plays a very important role in the battlefield environment. They help soldiers to maintain awareness of the sound of the battlefield environment at all times, without missing the command of the commander or the information of comrades in arms. Military bone conduction headset phones are generally more expensive, but the same technology is gradually being used in the civilian field. Engineers designed everyday use bone conduction headset phones that quickly became popular in just 2 years.
So what are bone conduction headset phones?
Bone conduction headphones, as the name suggests, are headphones that use human bones to transmit sound. The sound transmission method of this headphone is very special. It no longer needs to transmit sound through air and eardrum, but directly transmits sound to the auditory nerve of the inner ear through human bones, so that the auditory nerve can perceive the sound.
The way bone conduction headphones transmit sound eliminates the need for the headphones to be plugged into the ear, or to completely cover the entire ear. Therefore, there can be a new attempt in the way of wearing them, that is, the wearing method of the ear-hanging type that does not need to be in the ear. This also makes bone conduction headphones more comfortable to wear and better for the health of the ears.
How does bone conduction headset phones work
Bone conduction headset phones are a product that "attaches the sounding unit on the temple of the head, and the vibration of the sounding unit triggers bone vibrations, thereby transmitting the sound to the auditory nerve".
Normally, when the air vibrates, the eardrum vibrates and a person perceives sound. It needs to be clarified that it is not the eardrum that really feels the sound, but the cochlea. The eardrum is only one step in the sound transmission process. Vibrations of the eardrum are transmitted through the ossicles to the cochlea at the back of the ear where they are perceived as sound, which is how air conducts sound.
In the process of air conduction sound, there is a medium that is listening to the ossicles. So, is it possible to transmit sound directly from bones? It's possible, and it's real. The vibration caused by the sound unit drives the bones around the ear to resonate so that the sound signal is transmitted to the cochlea, which is perceived as sound by people. This is the principle of bone conduction technology.
After understanding the way sound is transmitted and the working principle of bone conduction technology, we can better understand how bone conduction headset phones work. When they are in working condition, as long as the sounding unit is pasted on the temple, the sounding unit converts the sound signal into mechanical vibration, drives the bone to vibrate, and transmits the vibration signal to the auditory nerve in the cochlea, thereby completing the transmission of sound. This is how bone conduction headphones work.
Their unique working principle brings them a lot of advantages
Advantages of bone conduction headset phones
Bone conduction headset phones have three very prominent advantages.
Advantage 1 of bone conduction headset phones: safer to use
Compared with common headphones, bone conduction headphones are placed on the cheekbones in front of the ears when in use. They conduct sound directly through the skull bone to the inner ear, keeping your ears open at all times, which does not interfere with any external ambient sound entering the ear. The wearer can even chat with friends around him while listening to music. Therefore, you can hear the sound of the outside world by wearing bone conduction headphones during outdoor sports, on buses and subways, running, and cycling. The wearer can maintain awareness of the surrounding environment at all times to avoid accidents. Therefore, they can provide higher security than common headphones.
Advantage two of Bone conduction headset phones : more hygienic to use
Whether it's headphones or earbuds, covering your ears when using them can make your ears stuffy, which can lead to the growth of bacteria inside your ears. Especially when the ear canal is blocked, the inside will become humid and hot, and bacteria will grow more rapidly. Therefore, wearing in-ear headphones is also one of the important reasons for many young people's ear canal inflammation. What about bone conduction headset phones? They don't cause these problems. Because they do not touch or cover the ears, they can keep the ears hygienic and clean.
Advantage three of bone conduction headset phones: more healthy use
Bone conduction headphones do not need to be worn in the ear, so the injury caused by the headphone rubbing against the ear canal is avoided. Moreover, the vibration wave of them is smaller than that of ordinary headphones, and the damage to hair cells in the ear can be reduced by about 80%. Therefore, bone conduction headphones are more ear-friendly and healthier to wear than common headphones.
Of course, bone conduction headset phones are not 100% perfect, and they have drawbacks, such as their sound quality being difficult to achieve the effect of traditional noise-canceling headphones. They really release the ears, which also lose the "sound insulation" or noise reduction effect of traditional headphones, so in extremely noisy environments, it will be difficult for bone conduction headphones to transmit sound to your inner ear. However, the sound quality of them has improved a lot compared to the previous two years with technological progress. Some mainstream brands like wissonly and aftershokz have excellent sound quality.
There are more and more brands of Bluetooth bone conduction headset phones in the market, so how to choose the right one?My suggestion is to pay attention to the two key points: sound quality and sound leakage reduction, and choose the brands with better technology accumulation.Here are five best headphones for you all.
1. Wissonly Hi Runner bone conduction headset phones
Reason for recommendation:
Wissonly bone conduction vibration unit optimization technology is one of the best technical solutions in the industry, because their team has accumulated in the field of bone conduction for 10 years, which is highly respected by people in the industry in terms of product quality and hearing protection.
Once, there was a saying that the sound quality of bone conduction headset phones was average. However, Wissonly Hi Runner refreshes this knowledge. It is excellent in sound quality. It uses a 360-degree bone conduction vibration unit, which can increase the vibration area by 35% compared with traditional bone conduction headphones. Moreover, its loss of bone conduction sound transmission is lower, making the sound more shocking and powerful.
Wissonly Hi Runner has added a number of innovative features to make bone conduction headphones better integrated into many scenes in life. It supports IPX8 diving waterproof, which is very good for me who loves swimming. What's crazy is that it can still work normally under 20 meters of water! It also has 32GB of memory, so it can play music even if it is not connected to a mobile phone. I basically use it as an MP3 player, and I don't take my mobile phone for running at night. It uses the Bluetooth 5.0 chip, and outdoor activities can make the connection more stable.
In terms of appearance, Wissonly Hi Runner adopts classic black color, and its simple appearance involves matching whatever clothes you wear in any scene.
2. Philips A8606 bone conduction headset phones
Reason for recommendation:
A8606 headphones are made of titanium alloy skeleton, wrapped with skin-friendly silicone material, which can not only keep the shape stable, but also cause no pressure on ears. The body fits auricle tightly, so it is easy to wear and can be used for a long time. This headphones adopts IPX5 waterproof design, so there will be no problem in drenching and sweating. The disadvantage is that the sound quality needs to be improved, and the sound leakage is also serious.
3.AfterShokz OPENRUN PRO bone conduction headset phones
Reason for recommendation:
Openrun PRO gives people the first impression that it is very light and almost forgets the feeling of existence. In terms of battery life,its continuous playing time can exceed 8 hours, which can be said to be a very strong bone conduction. AfterShokz brand is mainly developed for sports, but the only drawback is that the sounding unit is very slim, and it will feel a little oppressive when worn for a long time.
The function has IP67 waterproof coefficient, daily outdoor exercise, no fear of sweat, and normal washing.
4. Earsopen BT5 bone conduction headset phones
Reason for recommendation:
earsopen BT5 bone conduction headphones are originated in Japan and can play music continuously for up to 6 hours. They adopt IPX7 waterproof design, are not afraid of sweat in sports, and are very suitable for use in sports scenes. Their unique audio equalization technology and high-performance vibration unit support sound of different frequencies. BT5 have an echo reduction function to minimize echo.
5.Nank Runner CC3 bone conduction headset phones
Reason for recommendation:
Runner CC 2 bone conduction headset phones adopt a combination of soft and hard to reduce sound leakage. The entire headphones adopt a seamless design, even the headset mic is wrapped in silicone. The unique sound leakage cancellation technology can greatly reduce the leakage phenomenon.
It uses magnetic charging, after each use, you only need to put the magnetic tip in the buckle position of the headphones. Compared to traditional headphones, Runner CC2 bone conduction headphones has no holes in the entire body, and it has a certain waterproof effect.
It is generally a good entry-level bone conduction headphone. But the waterproof level is not enough, it is are not suitable rain or water sports.
Each of the above products has its own characteristics. You can choose according to your own needs. Wissonly and Aftershokz are my favorite brands. Their technology is relatively mature and the overall performance of their products is relatively good. Between the two brands, Wissonly will be more cost-effective and worth your money.
