What should I Pay Attention to when Choosing a True Wireless Noise Reduction Headset?

With the full popularization of noise reduction function in the real wireless headset market, Earphones with a price range of hundreds to thousands of yuan have noise reduction function. There are so many noise reduction earphones. Do you know how to choose them? What parameters should be considered when selecting headphones?

First of all, for the noise reduction principle, the active noise reduction earphone does not eliminate the noise, but uses another signal sound wave to neutralize the original noise. The noise reduction technology commonly used in active noise reduction earphones is the double feed microphone noise reduction scheme. The noise reduction of doubly fed microphone is also called hybrid noise reduction. There are two microphones on the earphone to identify the noise. The microphone outside the earphone is responsible for collecting the ambient noise, and the microphone inside the earphone is used to collect the noise in the ear canal. Through the built-in noise reduction chip and noise reduction algorithm of the earphone, the reverse sound wave emitted by the earphone can be offset. When purchasing earphones, you should first consider the true wireless noise reduction earphones with the double fed microphone noise reduction scheme. The noise reduction effect of the double fed microphone is better than that of the single microphone noise reduction scheme.

In addition, many earphones are now equipped with dynamic noise reduction. In many cases, our demand for noise reduction will change at any time. For example, we need high noise reduction effect in the subway, but sometimes the noise reduction is not so high because we have to communicate with colleagues at any time in the office. Many earphones now support dynamic noise reduction technology. The earphones help you determine the current noise reduction type, which eliminates the trouble of frequently manually adjusting the noise reduction intensity. Therefore, when purchasing noise reduction earphones, supporting intelligent matching noise reduction environment is also a bonus.

Another very important parameter is the noise reduction depth. Noise reduction depth usually refers to the peak noise reduction effect of headphones at a certain frequency. The higher the value it represents, the better the noise reduction effect. At present, the depth of flagship noise reduction earphones of all brands is about 40dB, and the noise reduction depth of earphones of mid-range brands is generally about 30dB. However, the noise reduction depth is only a reference for the noise reduction of earphones, and cannot directly represent the comprehensive noise reduction level of earphones. In addition, the depth of noise reduction is generally based on the frequency range of noise. Generally, noise reduction earphones have a good filtering effect on low-frequency noise, but the noise reduction effect on high-frequency noise is very limited.

Finally, the type of earphone is also important for noise reduction. Compared with semi earphones, in ear earphones have better airtightness, are more closely combined with the ear canal, and are less prone to sound leakage. Therefore, the noise reduction effect of earphones is better than that of semi earphones, which is why many semi earphones on the market do not have noise reduction function.

Make a purchase of Wireless Noise Reduction Headset from China, you can get them at a good price if you have a large quantity. We hope to be your long-term partner.
