Hearing Enhance Headphones (Hearable Devices, Hearing Assistive Device, or Hearing Buds), simply put, are enhanced headphones for people with mild to moderate hearing loss. It can realize some functions of hearing aids, such as segmental compression compensation of sound. Mainly for people with mild hearing loss due to long-term wearing of headphones and listening to songs at high volume, or people with gradual hearing loss due to age.

Hearing Assistive headphones are products between healthy headphones and professional hearing aids. The target group is 1 billion people with mild hearing loss. At the same time, it can radiate the healthy headphone market for the general public. It needs to have some functions of professional hearing aids, and at the same time have the fashionable appearance of ordinary earphones and healthy earphones.

People are increasingly concerned about hearing health issues. This is mainly because of two points:
(1) Modern technology and environment make it easier for people to be exposed to high volume, resulting in younger hearing loss and an increase in the proportion of the overall population.
(2) Hearing loss is irreversible and cannot be recovered once it is lost.


In daily life, modernization has brought a more exciting life to everyone, but also brought about hearing health problems. Excessive exposure to high-volume scenes such as karaoke, bars, concerts, cinemas, and sports venues may be harmful to hearing health; in addition, with the popularity of personal audio systems such as TWS headphones, more people often Listening to music and videos on mobile apps at unsafe volumes for a long time also poses a major threat to hearing health and makes irreversible hearing loss more common.

The World Health Organization (WHO) estimates that one in five people in the worldwide has hearing loss problem, of which approximately 466 million have disabling hearing loss. If steps are not taken to reduce the risk factors for hearing loss, this number will continue to rise for decades to come.

At the same time, more than one billion young people worldwide may be at risk of hearing loss due to unsafe listening practices. Nearly 50% of 12-35-year-olds in high- and middle-income countries are using personal audio devices (such as smartphones, TWS headphones, etc.) at unsafe and excessive volumes, and nearly 40% are exposed to In bars, discos, nightclubs, etc., at high volume levels that are potentially harmful to hearing health.

Sound is distributed over a certain frequency spectrum. The sound we perceive is made up of vibrations of different frequencies and different loudnesses. The level of the frequency represents the sharpness or deepness of the sound. The higher the frequency, the sharper the sound, and the lower the frequency, the deeper the sound. For example, bird calls are high-frequency sounds, while dog barks are low-frequency sounds.


Different people’s hearing, left ear and right ear hearing, are different. Hearing test is to find out the minimum loudness (minimal hearable) people can hear at different frequency points to determine the level of hearing loss. 0-20dB is normal hearing, 20-35dB is mild hearing loss, 35-50dB is moderate hearing loss, etc.

Therefore, a person with a hearing test result of 20-50dB is a person with mild to moderate hearing loss. They can’t hear small or faint sounds, such as wind blowing in the woods, conversation, etc. Because the hearing loss of the above-mentioned levels cannot hear the voice clearly, they will unconsciously turn up the volume on the phone or listening to music, which will lead to further hearing loss.

People with mild to moderate hearing loss will encounter some problems in their lives, such as:
People who are far away in the meeting cannot be heard clearly;
In a noisy environment (low signal-to-noise ratio), it is difficult to hear friends talking;

In this regard, the auxiliary hearing headphones need to perform a hearing test to measure the user’s hearing loss value at different frequency points, and then perform segmental sound enhancement (loudness compensation). In addition, in terms of product form, people with mild to moderate hearing loss have not yet seriously affected their lives because of their hearing loss. People with mild hearing loss expect to improve their hearing, but do not want to wear hearing aids to give people a feeling of disability.

In general, the core demands of people with mild hearing loss become the following three points:
(1) Quick hearing test
(2) Sound gain or personalization under the condition of protecting hearing health
(3) The products are fashionable and popular, and there is no sense of disability

Shenzhen WinTo Technology Co., Limited have been committed to develop premium hearing enhance headphones for people with mild hearing loss since 2019.
