Therefore, ZAKE Technology began a survey on Bluetooth noise-canceling headphones, summarizing from four thousand questionnaires that more than half of the people using Bluetooth noise-canceling headphones had discomfort in their ears, including itching, pus, allergies, and other symptoms, and that more than 12% of the people had discomfort on a regular basis. According to this ratio, there may have been nearly ten million people in China who were affected by the physiological impact of headphones.
Noise-canceling headphones were first used in space flight, but when did they start to be integrated into our lives? Probably in the downstairs more and more square dance music, more and more people on the subway noise, life is changing rapidly to bring the negative sound of the life of the time, noise-canceling headphones market gradually be opened, and quickly into our lives.
The blue ocean of noise-canceling headphones began to attract major manufacturers. But in May this year, the State Administration of Market Supervision for the market for active noise-canceling headphones risk monitoring, involving 47 companies 60 pairs of headphones, the maximum sound pressure level, the amount of active noise reduction, the amount of integrated noise reduction and other items were tested, the test results found that fifty percent of the headset noise reduction is not enough, not only can't effectively protect the hearing, there is a certain risk of hearing damage, even if it is a little more expensive, the better a better class of noise-canceling headphones. Even if the price is a little better than a class of high-quality noise-canceling headphones, you can do to shield a part of the noisy environment of the noise, there is also a risk.
Taking a look at a few of the mainstream manufacturers on the Black Cat complaint platform, the complaints are that wearing the brand's headphones leads to adverse physiological reactions. However, so far there is no relevant data to confirm that the headset is a direct cause of ear problems, only to show that there is a strong positive correlation between them. The relevant medical experts said that the ear problems may also be related to the way of wearing, wearing the length of time and other human factors.
But whether it's a problem with the headset itself or human factors, we can't deny that headphones do carry some risk. In this regard, more and more headset manufacturers are optimizing their products in terms of comfort, noise reduction, etc., in order to get more users' recognition, so as to stand firm in the market. For example, OPPO Enco Air Bluetooth noise-canceling headphones, which are equipped with DNN algorithms to achieve high-quality deep call noise reduction effect, and in terms of comfort, the use of semi-in-ear ergonomic design that fits the natural curve of the ear, bringing nearly senseless wearing, realizing the technology is more humanized.
It is also worth mentioning that not long ago, OPPO publicized a new patent on noise-canceling headphones, called "headset configuration method, device, terminal device and computer-readable storage medium", applied to terminal devices.
I have to say, as an internationally recognized technology company, and as a domestic brand, in the wireless noise-canceling headset this piece of OPPO is really outstanding, and has even walked in the forefront of the industry.
