Noise reduction earphones are earphones that can reduce external noise, also known as "Active noise control earphones". They use built-in microphone and electronic circuit technology to detect and analyze ambient noise, and generate opposite sound waves to shield external noise. This allows people to enjoy a better music experience or better call quality in noisy environments.
Noise reduction earphones are usually divided into two types: one is a fully enclosed noise reduction earphone, which completely encloses the ears and can reduce external noise by more than 90%; Another type is a semi open noise reduction earphone, which can reduce most of the external noise but not completely sound insulation. Noise cancelling headphones can also be used through Bluetooth or wired connections.
The advantage of noise reduction headphones is that they are very convenient to use. Simply put on the headphones or turn on the noise reduction function to experience the noise reduction effect, which can help people avoid being disturbed by noisy environments during work or travel, and improve work and rest efficiency. In addition, noise cancelling headphones also help protect hearing and reduce the damage caused by high volume to the ears.
At the same time, noise reduction headphones also have some drawbacks, such as higher prices, longer charging times, and noise reduction effects influenced by external environments. You need to choose whether to purchase noise reducing headphones based on your own needs and actual situation.
