在过去的2年中，无线蓝牙骨传导耳机越来越受欢迎。无论你是出去跑步、骑自行车还是去健身房，你都可以看到有人穿着它们。作为明星科技产品，它们与普通耳机有很大不同。毫无疑问，它们不是另一种耳机，而是另一种耳机。
它们最大的区别是传输声音的方式。无线蓝牙骨传导耳机使用骨骼来传输声音，而常见的耳机是使用空气传输声音的空气传导耳机。
声音传输模式的差异使得您无需将无线蓝牙骨传导耳机塞入耳朵，只需将振动单元连接到太阳穴即可让耳朵听到声音。
无线蓝牙骨传导耳机有哪些优势？
首先，由于它们使用骨传导的原理来传输声音而不是空气传导，因此大多数无线蓝牙骨传导耳机在使用时不会影响双耳对环境声音的采集。因此，在户外使用时非常安全，佩戴时不会因为沉浸在音乐中而忽视可能的危险。
其次，因为它们大多靠近硬骨位置（耳朵旁边），而不是像入耳式耳机那样直接堵塞耳道，或者像夹式耳机那样夹住耳朵的软组织。长时间佩戴无线蓝牙骨传导耳机后，耳机的耳朵损伤原因远小于入耳式耳机或夹式耳机。例如，如果你戴了四个小时，夹式耳机可能会导致你的耳朵难以忍受地疼痛，但即使长时间佩戴无线蓝牙骨传导耳机，你也基本上什么都感觉不到。因此，它们佩戴起来非常舒适。
最重要的是，普通耳机会堵塞耳道，导致大量细菌的生长，从而导致耳部感染。无线蓝牙骨传导耳机没有这些效果，因为它们不需要戴在耳朵里，佩戴时也不会与外耳道摩擦。所以它们更适合油性耳朵、中耳炎、小耳朵的人，以及一些耳朵敏感的人，因为它们不需要插入耳朵。它们也更适合需要长时间戴耳机的人。因此，无线蓝牙骨传导耳机非常健康。
无线蓝牙骨传导耳机的听力损伤相对较小，因为听力损伤一般发生在鼓膜和内耳，而无线蓝牙骨传导耳机直接绕过鼓膜以避免耳膜损伤。而且它们的振动波比较适中，对听觉毛细胞的影响会小一些，所以它们对听力造成的伤害是最小的。由于这些原因，无线蓝牙骨传导耳机近年来变得非常流行。
当然，无线蓝牙骨传导耳机并不完美，它们也有其缺点。
首先是音质不如传统耳机，因为它的佩戴方式。由于其设计特点，在购物、乘坐地铁、乘车等嘈杂环境中的抗干扰效果并不理想。因为它是通过皮肤和颅骨传递到耳小骨的，所以它们的音乐再现程度不如传统的入耳式耳机。
The second is that the phenomenon of sound leakage still needs to be overcome. If there is a common problem with wireless Bluetooth bone conduction headsets, it is the problem of sound leakage. Although major manufacturers are trying to improve the sound leakage, judging from the actual status, sound leakage still exists in the headphones. Of course, mainstream wireless Bluetooth bone conduction headset brands, such as wissonly and Aftershokz, have made a lot of efforts to improve the sound leakage of wireless Bluetooth bone conduction headsets, and have almost solved the sound leakage problem.
The advantages and drawbacks are determined by their working principles.
How do wireless Bluetooth bone conduction headsets work?
First, let’s look at how we hear sound. The sound we hear every day, generally through the vibration of the air, first reaches the ear and vibrates the eardrum. The vibration transmitted to the eardrum further vibrates the auditory ossicles, and finally reaches the spiral organ — the cochlea, so that the sound can be perceived.
However, there are other ways of transmitting sound to the cochlea besides passing it through the eardrum. In fact, by vibrating the “bones” like vibrating air, the vibrations are transmitted to the cochlea. When the vibration reaches the cochlea, the cochlea perceives the sound and transmits the it to the brain center to form hearing. This is the sound transmission principle of bone conduction.
In our daily life, there are many cases of hearing sound through bone conduction. For example, when we eat biscuits, we can clearly hear the sound of the biscuits being crushed. Dolphins and whales are some of the best bone conduction animals in nature, using the bones near their jaws to catch vibrations in the water to hear sound.
Wireless Bluetooth bone conduction headsets are products that use bone conduction technology. When they work, they usually attach the sounding unit to the bones near the temple. When the vocal units vibrate, they vibrate the skull and transmit the vibrations to the cochlea, allowing sound to be heard. This is how wireless Bluetooth bone conduction headsets work.
Bone conduction headsets are becoming more and more popular among young people,and more and more brands join this field.So, which brand is the best?In my opinion, those brands that have accumulated technology in this field are trustworthy.Below, I have sorted out some good Bluetooth bone conduction headsets brands, and recommend them to you. I hope they can help.
1, Wissonly Hi Runner wireless Bluetooth bone conduction headsets
Reason for recommendation:
Wissonly wireless Bluetooth bone conduction headsets are the first brand I started to contact. When they recommended it on the online crowdfunding platform, I noticed it, after saw that many people were recommending, and I bought it. This Hi runner I used for a few months, and the overall performance was better than I expected.
Some wireless Bluetooth bone conduction headsets leak sound, and you know that I take privacy very seriously, so I’m very concerned about anti-sound-leakage technology. Wissonly Hi Runner does a very good job in the field. Its body is sealed, and through structural optimization and algorithm adjustment, its sound leakage is minimized. The official claim they can eliminate 90% of sound leakage. I do not have professional equipment to test, but I have tried and found that at 60%-70% volume, the sound is completely inaudible at a distance of 1.5 meters, which makes me very satisfied. I have actually compared it with other wireless Bluetooth bone conduction headsets, and the Wissonly Hi Runner has currently the best sound leakage reduction solution in wireless Bluetooth bone conduction headsets.
The Wissonly Hi Runner is also particularly comfortable in the wearing experience. Because the material of the whole machine is high-tech hypoallergenic silicone, and it is coupled with the ergonomic design that conforms to the structure of the human ear, so that users will not bring any burden to the ear under long-term wear.
Sound quality as the core performance is undoubtedly worth mentioning. Wissonly Hi Runner uses a large-sized vibration unit, the sound range is wider, the sound is more three-dimensional and deeper, so the sound quality is undoubtedly very good. And it is also equipped with a Bluetooth 5.0 chip, the connection is more stable. And it will not be disconnected when used, which is a good experience. The Wissonly Hi Runner also comes with 32GB of built-in storage that can store 5,000 songs, so you can use it completely as an MP3 player to enjoy music without your phone when you go out for a run.
2. Philips A6606 wireless Bluetooth bone conduction headsets
Reason for recommendation:
This Philips A6606 wireless Bluetooth bone conduction headsets, with its comfortable silicone surface, is comfortable to wear. It is ergonomically designed, so that it will not fall when it is firmly worn. Its IP67-level depth waterproof standard makes you easy while sweat during daily exercise. This model is equipped with a night run lamp device, and while running at night, it can make cyclists or vehicles notice you. This is a very thoughtful design. It is equipped with Bluetooth 5.2 technology, which has faster transmission distance and lower power consumption than 5.0, but this one can’t be used in swimming.
3.AfterShokz OPENRUN PRO wireless Bluetooth bone conduction headsets
Reason for recommendation:
OpenRUN PRO is good at anti-sound-leakage, it uses LeakSlayer leakage cancellation technology to reduce sound leakage. It is equipped with Qualcomm QCC3024 chip that uses 5.0 Bluetooth protocol, that supports dual-device connection, and that performs very well in terms of stability, compatibility, effective range and delay time. It is IP67 waterproof grade, which is enough to allow it to be used in daily life. But you can not wear it to swim in the water. As a high-end bone conduction sports headphones this is still a pity. And it does not have built-in memory, can not be used as an MP3 player.
4.earsopen SS900 wireless Bluetooth bone conduction headsets
Reason for recommendation:
Different from other wireless Bluetooth bone conduction headsets, this earsopenSS900 is mainly worn by pinching ears, which requires both hands to finish wearing. Its’ IPX7' s waterproof grade can achieve the effect of short-time immersion under water, and it is easy to face the daily sweat. The 8g single side headphone body can play a comfortable and non-inductive role in the whole wearing process, but it will be a little uncomfortable when worn for a long time due to the wearing way of clip ears.
5.Haylou PurFree wireless Bluetooth bone conduction headsets
Reason for recommendation:
Haylou PurFree performs well overall, the headphone is only weighs 28g, there is almost no weight sense to wear. And the surface of the headphones is made of soft materials, and the wearing comfort is good. In terms of sound quality, it is also equipped with directional audio directional technology. It is a technology that allows the timbre to be concentrated and dive deeper at low frequencies, so that the rhythm of the song will be stronger. The battery life is good, and it lasts for 8 hours of music playback.
The waterproof grade is not high, and there is no built-in storage, which may be its disadvantage.
Among the several bone conduction headsets recommended above, wissonly and aftershokz are my favorite brands. Compared with them, Wissonly is more cost-effective and worth buying.
