The first contact with bone conduction headsets was at a high-tech exhibition at the National Convention Center in 2012.
When I first smelled bone conduction, it was difficult to understand, and the sound actually traveled through the bones? Shouldn't you convey the eardrum from the ear canal and perceive sound?
There were so many people at the booth that I squeezed to the front, tried it on just once, and then I was squeezed out again.
After I came back, I looked up some information about bone conduction headphones to understand how it works.
Bone conduction headphone principle
In fact, the working principle of bone conduction headphones, as long as it is understood, is very simple.
The principle of bone conduction headphones: it is to conduct sound through the resonance of bones, and transmit sound waves through the human skull, bone labyrinth, inner ear lymph, spiral, and auditory center.
For example: when we eat hard and crunchy foods such as nuts and cookies, do we hear the sound of our chin chewing? This sound is transmitted through the bones of the teeth to the nerves of the ear, so that the sound of chewing food can be heard.
Therefore, bone conduction headphones through the above principle, you can achieve that the earphones do not need to enter the ear, you can hear the sound.
Compared with the traditional sound conduction method (air conduction) that generates sound waves through the diaphragm, bone conduction itself eliminates many steps of sound wave transmission, and can clearly restore sound in a noisy environment, and sound waves will not affect others because of diffusion in the air, and the experience produced is completely different from traditional earphones.
How to distinguish a prosthetic bone conduction headset
Understanding the working principle and advantages and disadvantages of bone conduction headphones, we can distinguish between real bone conduction headphones and fake bone conduction headphones.
In fact, most of the fake bone conduction headphones still use the principle of air conduction headphones, which enter the ear canal through sound waves and act on the eardrum to conduct sound. So these headphones have the following problems that are difficult to trim exposed:
1、Waterproof performance difference
Because air conduction headphones need to transmit sound to the air, those counterfeit products must leave the sound hole of the speaker in the product, it is because of the existence of these sound holes, fake headphones can not be as extreme as bone conduction headphones in waterproofness. In sports scenarios that are easy to sweat, product failure problems caused by sweat erosion are more likely to occur, not to mention some wading scenes.
2. The problem of sound leakage is serious
The reason for the design of air conduction headphones, if you follow the wearing method of bone conduction headphones "not in the ear", but its sound unit is still an ordinary speaker, this form of external music will inevitably lead to a very serious sound leakage problem.
3. The sound quality effect is unbearable
Similarly, air conduction headphones transmit sound to the air, if it does not enter the ear, only part of the sound will be accurately transmitted to the ear canal, and other sounds are spread out with the air, resulting in the loss of sound, and the sound quality is naturally not ideal.
One trick to distinguish authenticity
If you want to use the simplest way to distinguish the authenticity of bone conduction headphones, it is actually very simple. When we wear bone conduction headphones, wear earplugs or cover our ears, observe the change of the music of the headphones at this time, if the music sound becomes louder, the headphones are real bone conduction headphones, if the sound becomes smaller, the headphones are fake bone conduction headphones.

Unboxing
Dailing S800 bone conduction headset packaging introduction is bright, the main color is refreshing light green, set off the delicate and small, smart and fashionable sense of youthful design.
The back of the box is marked with the performance data and functional characteristics of the Daling S800 bone conduction headset, which we will show in the actual evaluation later.
After unpacking, the box mainly contains the main body of the earphone, and also comes with data cables, earbuds, lanyards and other accessories.
These functional accessories allow the Daling S800 bone conduction headphones to exert their better functional characteristics.
I chose the black model, which is more cool under the stylish exterior design.
The shape of Dailing S800 bone conduction headset is ergonomically designed, especially for Asian head-shaped ear shapes and wearing habits, using skin-friendly silicone and matte touch, highlighting high-grade vitality.
Simple multi-function button design, so that the basic operation is no longer cumbersome, simple touch, can meet a variety of functions. The raised design on the physical button allows you to easily find the required function keys during exercise or during weekday leisure without canceling the headphones, eliminating false touches.
Try the experience
At present, my family and I are wearing Dailing S800 bone conduction headphones for about a week, so I will talk about the experience in detail.
First of all, Dailing S800 bone conduction headset has the basic characteristics of bone conduction headset.
It is comfortable to wear, there is no stimulation to the outer ear and ear canal, and its surface material and shape design can make the earphone fit the user's skin more naturally, and will not feel discomfort such as strangler and clip. Even if worn continuously, there is no discomfort in the ears. You don't need to wear in-ear headphones like before, and you basically have to take them off to rest your ears in an hour.
The sound quality is also very satisfying to me. The music enters the inner ear through the bones, directly captured by the brain, and the high, medium and low frequencies are balanced, and the sound is full and full, as if present.
This excellent sound quality is fully due to its 14mm large unit stereo surround sound design, HIFI-level tuning, and a 14mm bone conduction oscillator, which makes the headphones' music performance exceptionally good.
Other features
In addition to the basic characteristics of sound quality, the Daling S800 bone conduction headphones also enjoy several other features.

The full body closure waterproof structure, sweatproof and spill-proof, allows users to enjoy the listening process.
3. Magnetic charging leakage protection
The body of the earphone has four gold-plated contacts for connecting charging, expensive low-power components, imported button cycle charging, the battery specially adopts magnetic adsorption charging design to replace the traditional socket charging design, which can prevent liquid erosion from causing charging socket failure. It is safe to use and improves the service life of the product.
Price
I have also used several bone conduction headphones on the market to meet the demand, and the price is generally around 800-1000 yuan, while the price of Dailing S800 bone conduction headphones is only less than 300 yuan, and the cost performance is very cost-effective.
summary
Overall, this Dailing S800 bone conduction headset almost meets all my needs for sports headphones, cost-effective, and its near-perfect sound quality far exceeds my inherent impression of bone conduction headphones, IPX8 level waterproof, Bluetooth 5.3 chip and other functions, greatly exceeding my basic expectations for it. More usage features, I still have to dig deeper.
