Is there anything you use? The Ministry of Industry and Information Technology announced that only two noise-cancelling headphones have obtained A-level certification

Headphones have become a must-have for many people to go out. Whether on the road, on the subway or in coffee shops, people wear headphones everywhere, shield themselves from outside sounds, and immerse themselves in the world of music. However, wearing headphones for a long time or causing the sensitivity of the ear to decrease can cause hearing loss in the long run. Therefore, many brands have also begun to introduce noise-cancelling headphones. However, according to the Ministry of Industry and Information Technology, only two noise-canceling headphones have obtained A-level certification, namely the Small Active Noise Cancellation Smart Headphones Pro and the Wanderer NeoBuds pro.

Among them, the small headphones use dual active noise reduction technology, the maximum noise reduction depth can reach 40dB, and support dual microphones to detect environmental and in-ear noise. Moreover, the headset supports real-time call recording to text, voice intelligent navigation function, and the battery life is up to 35 hours.

Wanderer headphones NeoBuds pro adopts a unique cavity structure that conforms to the diaphragm dynamic coil plus Lou's moving iron, and makes the coil iron unit fully displayed by active electronic crossover DSP, equipped with hybrid active noise reduction technology, and the noise reduction depth can reach 42dB. In addition, the headset is equipped with a new three-microphone call noise reduction algorithm and wind noise detection mechanism, which supports ambient sound monitoring and can last up to 20 hours.

Experts suggest that in addition to purchasing qualified noise-canceling headphones, you should pay attention to using your ears when wearing headphones, and follow the principle of "double 60" headphones, that is, the volume of headphones should not exceed 60% of the maximum volume, and the continuous use time should not exceed 60 minutes.
