Therefore, ZAKE Technology began to investigate Bluetooth noise-reducing headphones. From 4, questionnaires, it was concluded that more than half of the users of Bluetooth noise-reducing headphones had ear discomfort, including itching, pus, allergies and other symptoms, and more than 12% of them had frequent discomfort. According to this ratio, there may be nearly ten million people in China who have been physically affected by headphones.
Noise-reducing headphones were originally used in space flight. When did they start to be integrated into our lives? Probably when there are more and more square dance music downstairs and the noise of more and more people on the subway, and the negative sound brought by the rapid change of life is full of life, the noise-reducing earphone market is gradually opened and quickly integrated into our lives.
the blue ocean of noise-canceling headphones has begun to attract major manufacturers. However, in May this year, the State Administration of Market Supervision conducted a risk monitoring on headphones with active noise reduction in the market, involving 6 pairs of headphones from 47 companies, and tested maximum sound pressure level, active noise reduction, comprehensive noise reduction and other items. The test results showed that 5% of headphones had insufficient noise reduction, which not only failed to effectively protect hearing, but also had a certain risk of hearing damage. Even a kind of noise-reducing headphones with slightly higher price and better quality could shield some noise in noisy environment.
Take the mainstream manufacturers on the black cat complaint platform as an example, all the related complaints are caused by wearing brand headphones, which leads to physiological adverse reactions. However, so far, there is no relevant data to prove that headphones directly cause ear problems, which only shows that there is a strong positive correlation between them. Relevant medical experts said that ear problems may also be related to human factors such as the way of wearing and the length of wearing.
However, whether it is the earphone itself or human factors, we can't deny that the earphone does have certain risks. In this regard, more and more earphone manufacturers optimize their products in terms of comfort and noise reduction, so as to gain more users' recognition and gain a firm market. For example, the OPPO Enco Air Bluetooth noise-reducing earphone, which is equipped with DNN algorithm, achieves high-quality deep call noise reduction effect, and adopts a semi-in-ear ergonomic design that fits the natural curve of the ear in comfort, which brings almost no feeling of wearing and realizes technology. More humanized.
what's more worth mentioning is that not long ago, OPPO disclosed a brand-new patent on noise-reducing headphones, which was named "earphone configuration method, device, terminal equipment and computer-readable storage medium" and was applied to terminal equipment.
I have to say that, as an internationally renowned technology company and a domestic brand, OPPO is really outstanding in wireless noise-reducing headphones, even at the forefront of the industry.
