Today, let's talk about bone conduction headphones.
The concept of bone conduction headphones has been around for more than two years, and its principle is to transmit sound through bones, but it is not well understood, and even users who have experienced bone conduction headphones have mixed reviews. The good thing about bone conduction headphones is that they do not enter the ears and do not hurt the ears, which can effectively protect the hearing; The disadvantage is that the cost performance is not high, the application scene is limited, the wearing is either in sports, or in a private space, and few people wear bone conduction headphones in public places.
I have experienced several bone conduction headphones that range from ** to this evaluation:
If you're looking for sound quality, I don't recommend buying bone conduction headphones, which have poor sound quality compared to traditional in-ear headphones, because sound is transmitted through the bones rather than directly through the air into the ears; Most bone conduction headphones have sound leakage problems, let's not talk about the privacy content of the call for the time being, as long as the sound of the headset is loud enough, it is quite an external speaker, which directly affects the people around you.
If you need to listen to ** or other audio while exercising, bone conduction headphones can clearly perceive the surrounding sounds while listening to songs, which is more safe; Or if you are a high-frequency user of headphones, the in-ear use of bone conduction headphones can protect your hearing from damage.
If you fall into the latter category, it is right to use bone conduction headphones.
There are also many types of bone conduction headphones, and I have experienced two of them: one is the over-ear type, and the other is the neck-wrapping type. Take my commonly used Nanka bone conduction sports headset runner3 as an example, its wearing method belongs to the latter, whether it is running, cycling or swimming, it can be firmly hung on the ear without falling off. 
Among the several bone conduction headphones I have experienced, the South Carolina runner3 is a slightly more cost-effective bone conduction sports headset. Why? It is mainly reflected in the following points:
1. *South Carolina runner3** is less than 500 yuan, and the ** of my other bone conduction headphones are close to four figures. Although there is a big difference in **, there is little difference in the overall experience. If the South Carolina runner3 is close to 500 yuan for just a bone conduction headset, I wouldn't recommend it to anyone. In fact, it is a sports headset with *** function, that is, you can listen to it without having your phone around**.
2. Weight. The weight of the South Carolina Runner 3 is only 34g, and you can hardly imagine that such a pair of headphones is so light, giving people a zero-sense wearing effect. Many times ** stopped, I forgot that I still had a pair of headphones hanging from my ears.
3. Waterproof. The waterproof level of Nanka Runner3 has reached IP68 level, which can be regarded as a professional swimming waterproof, and it is definitely a blessing for friends who want to listen to songs while swimming! Although I don't swim, I sweat every time I run, and the South Carolina runner 3 has such a waterproof level, so I'm not afraid of sweat damaging the headphone components. 
Fourth, battery life. Nanka Runner3 adopts magnetic charging mode, which can not only avoid the problem of difficult cleaning of traditional interfaces, but also avoid the easy deformation of the charging port and improve the service life of the product. The earbuds have a built-in 230mAh large-capacity lithium battery, and the official battery life value is 8 hours. Many experiencers didn't expect that the South Carolina runner3 also has fast charging technology, which can listen to songs for two hours after charging for 10 minutes, and only take two hours to fully charge from zero!
5. Bluetooth. Nanka Runner3 adopts Bluetooth 5,3 low latency chip, with ceramic antenna and signal booster, the signal transmission is increased by 2 times, and the signal is still stable and not stuck at a distance of nearly ten meters from the measured partition wall.
6. Miscellaneous. In addition to the above functions, Nanka Runner3 also has ENC intelligent noise cancellation, which recognizes human voices and noises and improves speech intelligibility. In my opinion, South Carolina runner3 is more suitable for student parties, especially teenagers in the growth stage. The in-ear wearing method can avoid ear damage caused by long-term use of the earphones, and at the same time, the South Carolina Runner3 is closed by OT anti-leakage technology30, can reduce 90% of the sound leakage problem, no longer worry about the dormitory *** will affect the Xi of other students. 
Back to me,I don't usually use mobile phones for children,Textbook poems and English and other audio files,I copy all of them into the headset,South Carolina runner3Built-in16G memory,Able to store 3,000 songs,Even if it is not a problem to save the audio materials of the entire grade,You can learn Xi anytime and anywhere。
Summary: Whether bone conduction headphones are worth buying or not depends entirely on your needs. If you're looking for sound quality, then I don't recommend you buy it; If you love to listen to sports, Nanka bone conduction sports headphones runner3 is designed for you and will become your new sports partner! In addition to ensuring that the headphones do not fall off when you are exercising, the built-in *** function allows you to hear it anytime and anywhere away from your phone**.
