I am a deep user of bone conduction headphones and I love this new product. I wear them both for running and cycling. Obviously, they're already part of my body and give me a lot of motivation when I'm exercising. However, since this year, I have discovered some bad phenomena, that is, there are many fake bone conduction headphones on the market. They are cheap and of poor quality. This has me stuck when it comes to gifting my girlfriend's birthday. She thought that what I sent was cheap and inferior products, and we almost had a relationship crisis. Therefore, in this article, I want to talk about how to distinguish between real bone conduction headphones and fake bone conduction headphones, the principles, advantages and disadvantages of them, and so on.
How to distinguish real bone conduction headphones from fake ones?
Bone conduction headphones rely on bones to transmit sound. Fake ones are actually air-conduction headphones that rely on air to transmit sound. There is a big difference in the way of sound transmission. Fake bone conduction headphones (that is, air conduction headphones), emit sound from two external speakers, and the sound transmits sound through the air into the ear. Therefore, under normal social distance, the sound played by fake bone conduction headphones can be heard by everyone, while with real ones, within the same distance, other people can't hear the sound at all.

You can do a test and put on the headphones. If you wear real bone conduction headphones, you will find that the sound is louder and clearer after the ears are blocked. And if you wear fake ones , the sound becomes smaller after you block your ears.
How do wireless bone conduction headphones work?
When it comes to the working principle of bone conduction headphones, you must first understand the "essence of sound". Simply put, the sounds we hear every day are vibrations in the air. For example, have you ever seen a scene of “loud high-pitched sound shatters a glass window”on TV? This phenomenon is caused by the treble that transmits strong air vibrations to the glass window, causing the glass window to resonate.
We hear sound as vibrations in the air. Sound travels through the ear canal to the eardrum, then through a spiral organ called the cochlea to the brain, where it is finally perceived by us. While standard headphones that fit into the ear canal use this "standard" path to transmit air vibrations to the brain,wireless bone conduction headphones work quite differently.

The sound transmission path of standard headphones: sound source vibration → external auditory canal → eardrum → cochlea → brain
The sound transmission path of wireless bone conduction headphones: sound source vibration → skull → cochlea → brain
So, with bone conduction headphones, you can enjoy music without ear canals or eardrums. Bone conduction headphones do not need to be plugged into the ear canal when worn, which will cause less damage to the eardrum and better hygiene for the ear canal, so they are the healthiest headphones.

When your understand how bone conduction headphones work,You may know that they are a healthiest headphones.If you are interested in them, here are 5 excellent products for you.

1.Wissonly Hi Runner wireless bone conduction headphones

Reason for recommendation:
Wissonly is a headphone brand that attaches great attention on health, and that does not hurt the ears. Their team is also the first one to design non-in-ear headphones that are used to listen to songs. They began to explore the application of bone conduction technology to Bluetooth headphones as early as 10 years ago. After 10 years of accumulation, they have made great progress in the sound quality improvement and sound leakage reduction of bone conduction headphones. And these technologies are applied to their Wissonly Hi Runner headphones, their flagship product.
In order to solve the problem of sound leakage of bone conduction headphones, wissonly developed full closed sound leakage reduction technology. They comprehensively improved the vibration of the headphones, body design, software optimization and other directions. They finally reduced the sound leakage by 90%.
In terms of sound quality, most of the bone conduction headphones have average sound quality, but the sound quality of Wissonly Hi Runner is undoubtedly better in bone conduction field. They used a large-sized vibration unit, and through structural optimization, and finally increased the effective vibration area, so that the sound range was wide. The official claimed sound quality reach the HIFI level, but I don't think that they reached. They are just close to the HIFI sound quality, which is enough to satisfy me.
The excellent performance of these two characteristics, sound leakage reduction and sound quality, makes Wissonly Hi Runner have the basic conditions to become an excellent bone conduction headphone. Their other configurations are also very good. They are with a built-in 32GB of memory, and can play music even without connecting the phone. You can use them as an MP3 player. They support IPX8 waterproof level in swimming, even in underwater scenes that do not support Bluetooth, they can be used with MP3 function.

2.Philips A7607 bone conduction headphones

Reason for recommendation:
The sounding unit of the 7607 bone conduction headphone use a 17mm vibrator, which makes its sound have good penetrating power. What makes me even more surprised is that Philips A7607 is equipped with LED night run lamp at the rear of the its body, which has three kinds of brightness that can be switched. It is suitable for wearing at night, which can make people around you perceive their own position and further increase the safety factor. The waterproof performance of IPX6 grade is fully qualified for waterproof work in daily life, and even can withstand a small amount of rain intrusion.

3.AfterShokz OPENRUN PRO wireless bone conduction headphones

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 peace tw-1 bone conduction headphones

Reason for recommendation:
It is IP67 waterproof grade, easily resistant to sweat, and even capable of a short immersion underwater, but not suitable for swimming. The lightweight body just weighs 9g,its clip-on wearing method is novel.At the same time,It has a certain stability. But it is not suitable for long-term wear, and there will be a lot of discomfort.
5.Nank Runner CC3 wireless bone conduction headphones

Reason for recommendation:
Runner CC2 is made of titanium alloy, with a body weight of 28g, and the overall wearing experience is good. The sound quality and sound leakage are better than their previous products, but they still need to be improved. The headphones also support high-definition call noise reduction, which is a plus.
The ability of this headphone is relatively average, and there are no special highlights or obvious shortcomings. As an entry-level bone conduction headphone, it is still qualified.
It should be noted that the prices and functions of the above products are different. You can choose them according to your needs. I prefer the products of Wissonly and Aftershokz. Their sound quality and sound leakage reduction are excellent. I have been using Wissonly recently. It has a very high cost performance ratio. I like it very much.
