Apr 04,2023 | David
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 wireless Bluetooth 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 wireless Bluetooth bone conduction headphones are generally more expensive, but the same technology is gradually being used in the civilian field. Engineers designed everyday wireless Bluetooth bone conduction headphones that quickly became popular in just 2 years.
So what are wireless Bluetooth bone conduction headphones?
wireless Bluetooth 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 wireless Bluetooth 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 wireless Bluetooth bone conduction headphones more comfortable to wear and better for the health of the ears.
How do wireless Bluetooth bone conduction headphones work
If you want to understand how do wireless Bluetooth bone conduction headphones work, you must first know what “bone conduction” is. “Bone conduction” is one of the two main ways of sound transmission (the other is air conduction). It transmits sound through the mandibular bone of the human body to the cochlea. And then sound stimulates the auditory hair cells in the cochlea, thereby generating electrical signals that allow us to hear sound. These technical principles may sound obscure, but there are also cases of “bone conduction” sound transmission in life. For example, when eating, we can clearly hear the chewing sound; we still can clearly hear our own voice when covering our ears and speaking. These are “bone conduction” that helps us to hear sound. Take hearing the sound of chewing when eating as an example, during the eating and chewing process, the vibrations caused are transmitted through the bones to the inner ear to get us to hear sound.
Wireless Bluetooth bone conduction headphones are headphones based on bone conduction technology. The working principle is to use the vibrator on the sound unit to turn the sound signal into mechanical vibration, which causes bone resonance and conducts sound to the inner ear, so as to achieve the result of listening by”bone conduction”.
Do wireless Bluetooth bone conduction headphones have disadvantages?
While wireless Bluetooth bone conduction headphones are popular, they’re not perfect. They also have some disadvantages, summed up in three:
Disadvantage 1 : sound quality
Because of the design characteristics of wireless Bluetooth bone conduction headphones, their anti-interference effect is not ideal when wearing them for shopping, subway, car and other noisy environments. And the sound quality is not as good as traditional headphones, because they transmit sound through the skin, skull and then to the ear ossicles, so the degree of music reproduction is not as good as traditional in-ear headphones.
Disadvantage 2 : sound leakage
The sound is transmitted through the vibration of the vibrator, so part of the sound is also transmitted through the vibration of the air, and sound leakage cannot be completely avoided. It’s just that some headphones invest more research and design in reducing sound leakage, and solve most of the sound leakage problems. For example, the Wissonly Hi runner wireless Bluetooth bone conduction headphones I own are excellent representatives among them.
Disadvantage 3 the price is slightly higher
The technology of wireless Bluetooth bone conduction headphones is more complicated than that of traditional headphones, the materials are better than traditional headphones, and the manufacturing process is more complicated, which ultimately makes the price of them a little higher. But this year, with the rapid popularity of them, their prices have dropped significantly after the production has increased significantly.
Although wireless Bluetooth bone conduction headphones have the above disadvantages, compared with these disadvantages, they have more prominent advantages, such as being safer, healthier, more hygienic, and more comfortable to wear. These advantages make it popular among young people.
A large number of earphone manufacturers have joined the field of bone conduction headphones. Which one is the best? I will give you some recommendations
1. wissonly Hi Runner wireless Bluetooth bone conduction headphones
Recommended reason
Wissonly’s core team is a team engaged in the research and development of bone conduction products earlier. They have accumulated 10 years’ technology in this field. They have adopted the best acoustic laboratory in the Eastern Hemisphere for sound adjustment. Wissonly Hi Runner has good technical solutions to the problems of sound leakage, sound quality and waterproof of pseudo-wireless Bluetooth bone conduction headphones.
Wissonly bone conduction vibrator adopts a unique full-wrapped design, which makes the vibrator work in a closed environment, reducing the impact on the shell, thus reducing the vibration of the shell and finally reducing the sound leakage by 90%.
Wissonly uses a large-size bone conduction vibrator, and the effective vibration area of the vibrator is increased by 35% through structural optimization. At the same time, the sound transmission direction is optimized, the sound loss is reduced, and the sound is more concentrated.
Wissonly Hi Runner adopts integrated molding technology, with no holes in the headphones’ body and it is no splicing, which realizes IPX8 waterproof, and can be used for swimming and bathing. Even in the depth of 20 meters, diving is no problem.
It also has 32G of built-in memory, which can store 5000 songs. You can use it as amp3 player when you don’t have a mobile phone.
In a word, Wissonly Hi Runner is a product with powerful functions, stable technology and high cost performance.
2. Philips A6606 wireless Bluetooth bone conduction headphones
Recommended reason
The A6606 uses a titanium alloy frame. It is very stable to wear during running and has less shifting, helping you to exercise without feeling weight. The unique way of transmitting sound of wireless Bluetooth bone conduction headphones bypasses the air, reduces noises, but is most afraid of having stethoscope effect. The A6606 is designed so that the frame of the headphones does not touch the back of the head, avoiding the “stethoscope effect” during exercise, so you can hear more precise and clear sound details.
3.AfterShokz OPENRUN PRO wireless Bluetooth bone conduction headphones
Recommended reason
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 headphones
Recommended reason
This wireless Bluetooth bone conduction headphone adopts the ear-clipping mode, and the novel wearing mode also makes it need to be worn with both hands. Moreover, there will be obvious discomfort of ear-clipping when worn for a long time. In the headphones’ body, the pressure control area is adopted, and the headphones can be controlled by clicking and double-clicking, etc. The single ear part weight of 8g basically has no weight sense during wearing. With the bone conduction vibrator technology newly developed by BoCo Company, it has a good performance in the low frequency range, but it has obvious sound leakage in the middle and high frequencies.
5. vidonn F3 wireless Bluetooth bone conduction headphones
Recommended reason
The weight of this wireless Bluetooth bone conduction headphone is only 29g, and there is comfortable when it is used, whether it is hanging on the neck or hanging on the ear for a long time. The charging port of F3 headphones is a universal standard MICRO-USB interface. The charging port is waterproof with a soft rubber plug, which is not connected to the body, so there is a risk of loss. The disadvantage is that the sound quality is average, and the sound leakage is serious.
I believe that through the above recommendations, you may already know how to choose bone conduction headphones. If you are still confused, it is recommended to choose a brand with good technology accumulation, such as Wissonly and Philips. Philips is a big brand, needless to say, but it is worth emphasizing Wissonly, which has a deep technology accumulation, better configuration, and higher cost performance.
