Many people think that the noise cancelling headphones are to help us eliminate all the noise except the music you listen, but it is not.

A true noise cancelling earphone is a type of earphone that uses some method to reduce noise. Mainly to meet the better noise shielding in the noisy environment, so as to experience better listening effects, such as in some noisy office, mechanical noise during flight, noise cancelling headphones can isolate most external connections noise (Active noise canceling headphones), so listening to songs will not be interfered by excessive external noise and can enjoy high quality music.

At present, here have two types of noise cancelling headphones in the market. They are Active noise cancelling earphone and passive noise cancelling earphone.

The active noise canceling function is to generate a reverse sound wave equal to the external noise through the noise reduction system, neutralize the noise, and achieve the effect of noise reduction. Active noise cancelling headphones with noise reduction circuit that competes with external noise. Most of them use a large head-mounted design, using the earphone cotton and earphone casing to block the external noise, and to be the first round of sound insulation. At the same time, in order to have sufficient space to install active noise reduction circuits and power supplies.

Passive noise reduction earphone mainly form an enclosed space by surrounding the ears, or use soundproof materials such as silicone earplugs to block external noise. Since the noise is not processed by the noise reduction circuit chip, generally only high frequency noise is blocked, and the noise reduction effect on the low frequency noise is not obvious.

So the effect of the active noise cancelling headphones is more obvious than that of the passive noise cancelling headphones, that’s why most user like the active noise cancelling headset.
