How to choose noise reduction headphones/ Earphones

Noise pollution has become more and more important. Business trips, daily trips, or work environments seem to make noise aside when we fall asleep. Since we cannot control noise sources, we can only stop it from entering our ears. As the user's noise reduction awareness increases, the demand for noise reduction headphones increases. The competition in the headset industry continues to intensify, and the progressive development of noise reduction headphones will become a hot trend in the future! So what are the advantages of noise reduction headphones and how to choose?

The active noise reduction function is to generate a reverse sound wave equal to the external noise through a noise reduction system, neutralize the noise, and thereby achieve the effect of noise reduction. Active Noise Cancelling Headphones have a noise reduction circuit that counters external noise. Most of them use a bulky head-mounted design. They can use earplug cotton and a headphone housing to block outside noise, and perform the first round of noise insulation. There is plenty of room to install active noise reduction circuits and power supplies.

Passive noise-reducing headphones mainly form a closed space by surrounding the ear, or use silica gel earplugs and other soundproof materials to block external noise. Because the noise has not been processed by the noise reduction circuit chip, generally only the high frequency noise is blocked, and the noise reduction effect on the low frequency noise is not obvious.

Noise canceling headphones bring the following benefits to users:
1. Creating a quality of life: Noise-reducing headphones were first used to reduce noise on aircraft. This is the most primitive use of noise-reducing headphones. In a variety of noisy environment noise, noise reduction headphones can maximize the elimination of ambient noise (depending on noise reduction level), allowing users to enjoy quiet travel life. For users who demand a high quality of life, noise-cancelling headphones do solve the problem of headaches and improve the quality of their lives.

2. Protecting the user's hearing: Noise reduction headphones can protect hearing. Why do you say that? We assume that the surrounding noise is constant and that the volume of a mobile phone that satisfies the need for listening when there is no noise reduction headphone is 20 cells; after the noise reduction headphone is replaced, only 10 cells can be used to satisfy the listening requirement because the noise is reduced. So from this point of view, noise reduction headphones for the protection of hearing is still very prominent.

How to choose noise reduction headphones, we can start from the following aspects:
1, see models, see parameters
In general, the word “noise reduction” is represented by the abbreviation “NC (Noise Cancelling)”, so most models of noise reduction headphones will have these two letters. Or there will be "active noise reduction". Some merchants may say “XXX headphones have noise reduction function” when they recommend products to impress consumers, and some of these businesses will wipe the ball and describe ordinary in-ear earphones (passive noise reduction) as noise reduction. Earplugs, although this theory is not wrong, but it does not meet the general understanding. If the headset model can not find NC, we can also see the parameters, you can also see if there is a battery, the majority of active noise canceling headphones on the box will have "noise decibels" and other text, generally the strongest drop The noise effect can reach 30 decibels, in order to determine this is an active noise canceling headphones.

2, select function
Because the work of noise reduction headphones can not be separated from the battery power supply, so the noise reduction earplugs are basically equipped with a battery box, of course, this also became the earplug wire controller. Taking into account the user's actual environment and methods, such as connecting the headset to the phone, this is a very common use, so some earbuds are equipped with a function to answer the phone, equipped with microphone noise reduction. There are other similar additional features, we can also have a targeted reference when selecting products.

3, after all, this is an earplug
Just like ordinary earplugs, we still have to care about the basic quality of the product, whether the wire and connector parts are easily damaged, and whether the sound quality is outstanding. As the noise reduction industry continues to improve, noise reduction earbuds and ordinary earbuds with the same price, the basic difference in the sound performance is not, which we need to carefully selected, in the end what brand of noise reduction headphones noise reduction and strong The sound quality is also good. Do not ignore the actual results because you attach too much importance to the brand name.
