Scientific planting on National Hear Day: Hear recommends wearing open-back headphones


It’s Ear Love Day again. In the current era of fighting against “curls”, in fact, many Generation Z born in the 1990s are very concerned about their own health and must go to the gym or yoga room after get off work. However, while exercising for physical health, many people neglect their hearing health. In gyms and outdoor places, you can often see users wearing various in-ear or over-ear headphones for various exercises. The pressure on the tympanic membrane and cochlear nerve cells due to the dynamic rhythm of high sound pressure for a long time can be imagined.

It’s the 25th National Ear Love Day. As a technology enthusiast, I would like to tell you how to choose sports headphones and why open-back headphones are more recommended.

If you search with the keyword “ear damage” on Douyin, Weibo and Xiaohongshu, you will see a lot of shocking cases of irreversible hearing damage caused by improper wearing of headphones or wearing headphones for too long. . The headphones mentioned here specifically refer to in-ear and earbud headphones. At the same time, for the post-90s generation Z who love citywalking, camping and outdoor sports, in addition to the discomfort of wearing headphones, in-ear and over-ear headphones isolate the external environment, which will also cause problems in complex outdoor environments. Security risks.

Sullivan, a world-renowned consulting organization, pointed out in the latest “Global In-Ear Open Headphone Industry Independent Market Research” report that wearing headphones for a long time may damage the eardrum. Wearing headphones for a long time will cause varying degrees of irritation to the eardrum and inner ear, especially when the sound exceeds 85 decibels, which may cause auditory fatigue. The sound of some high-frequency in-ear headphones can reach 110 decibels. Long-term wearing can cause damage or damage to the eardrum. In severe cases, it can cause dizziness, hardness of hearing, tinnitus, etc. And if you wear headphones for a long time and do not clean them regularly, they may breed too many germs. Germs will follow the earphones into the ears, causing otitis media or infection. As people pay more and more attention to their own health, more consumers are aware of the dangers of wearing in-ear headphones for a long time.

As mentioned above about the living and consumption habits of people in the Z era, as various sports become more popular, corresponding sports headphones are also ushering in an explosion. Among them, open-back headphones are loved by many consumers due to their safety, comfort and hygiene characteristics.

The open-back earphones are based on the contour shape of the human ear and use the multi-point support principle in geometric mechanics to disperse the wearing pressure. When worn, the earphones do not enter the ears or block the ears. There is no intrusion in the ears, no swelling and pain, and they are more comfortable to wear. At the same time, the fully open, non-in-the-ear design avoids hygiene problems, as well as health problems such as ear inflammation and lesions caused by ear canal closure. Due to its many high-quality features, Sullivan pointed out in his report that the future may usher in an era of fully open audio.

As for the representative product of in-ear open-back headphones, we have to mention Shokz’s popular OpenFit comfort zone. This is an open-back headset that won the VGP2023 gold medal as soon as it was launched. It uses directional sound field technology. The sound sources are placed according to a certain topological structure. By regulating the amplitude difference and phase difference between different sound sources, the intensity of the sound pressure in the space is controlled. Weak distribution to achieve specific spatial directivity. This patented technology allows the product to accurately and efficiently transmit sound without being worn in the ear, making listening more private. It also allows users to perceive outdoor environmental sounds in real time and protect mobile safety.

Another form of open-back headphones is represented by bone conduction headphones. If you are keen on running or follow marathons, you must have seen the Shaoyin OpenRun Pro bone conduction sports headphones worn by world marathon champion Kipchoge.

“Bone conduction headphones do not need to be placed in people’s ears, they only need to be hung above the ears. They are not only more comfortable to wear, but also help to protect the hygiene inside the ears. Compared with the sound waves generated through the diaphragm, Sound conduction method, this bone conduction solves the discomfort of wearing in-ear headphones and avoids a series of hygiene problems caused by sweating in the ears during exercise. Moreover, the damage to human hair cells will be greatly reduced, which is a A relatively healthy way to receive sound.” The Sullivan report used clear logic to explain why, relatively speaking, bone conduction headphones are more “ear-friendly” in sports scenarios.

It is worth mentioning that the newly released “Global In-ear Open Headphone Industry Independent Market Research” report shows that in 2023, in the in-ear open earphone track, Shokz Shaoyin won the first place in global sales in one fell swoop. the throne.

Returning to the original intention of this article, there is no one-stop external tool that can solve ear problems. In addition to choosing the right open-back headphones, for us individual users, we must be familiar with the “60-60” principle of using headphones: that is, the volume should not exceed 60% of the total volume, and the volume should not exceed 60% of the total volume. The time should not exceed 60 minutes. N years later, you are still a young man with clear eyes and “early ears”!
