Spatial audio? Active noise reduction? Real wireless headset purchase guide

In recent years, the sales of true wireless headphones have exploded. Counterpoint data shows that since 20 17, the shipment of true wireless headphones has entered a growth rate of at least double every year. Especially in 20 19, the shipment volume was almost three times that of the previous year, reaching the growth rate of 183%. By 2020 and 20021year, the growth momentum of true wireless headphones will continue.

True wireless headphones have become one of the most popular mobile phone accessories.

In addition to sales volume, the true wireless headset of 202 1 has also undergone many changes in technology and function, such as active noise reduction and the gradual popularization of transparent mode. This is both a good thing and a bad thing, so that everyone can experience the excellent noise reduction function without spending thousands of dollars, and at the same time, it forces everyone to consider more factors when buying, so that the already dazzling shopping process has a higher chance of rollover. This paper will combine the real wireless headset industry and market status, and point out the precautions for the purchase of real wireless headsets.

When a technology or product is still in a period of rapid development and immature, but has already left the experimental stage, the latest is often the best.

The active noise reduction function of a true wireless headset is a typical example. When 20 17 active noise reduction technology first came to the real wireless headset, the experience was not good. Early active noise reduction headphones have poor noise reduction effect, and after active noise reduction is turned on, it will also emit obvious noise floor, which will affect the sound quality. It was not until the Apple AirPods Pro of 20 19+00 that the active noise reduction reached the level of obvious effect and no negative image quality.

Apple AirPods Pro promotes the popularization of active noise reduction.

If you wanted to buy a true wireless headset that supports active noise reduction, you can't go wrong by directly choosing the latest Apple AirPods Pro.

Up to now, although everyone has more choices, the strategy of choosing new products first has not changed. Because the active noise reduction technology of true wireless headphones is still improving. Judging from the new products of 202 1, the active noise reduction ability of true wireless headphones has been obviously improved. Moreover, more manufacturers have begun to pay attention to the side effects caused by "ear pressure".

The rapid improvement of active noise reduction has not stopped.

What is ear pressure? The external sound shielded by active noise reduction is low-frequency sound. If the low frequency received by the human ear is unnaturally absent, the brain will have an illusion, which will lead to discomfort similar to the pressure difference between the inner and outer ears. This discomfort is called ear pressure. Theoretically, the better the noise reduction effect, the more serious the problem of earphone ear pressure. Therefore, in order to reduce the discomfort caused by ear pressure, manufacturers have to find a balance in the degree of noise reduction, or relieve ear pressure through other designs of headphones.

At present, there is no "perfect" design, so no matter what your budget is, it is safest to buy the latest headphones when choosing active noise reduction.

It is important to choose a good pair of headphones, but don't forget that headphones are accessories, so sometimes the collocation of headphones and objects is more important.

Previously, only AirPods series products had obvious differences in function and performance on different devices. Now more and more mobile phone manufacturers have launched their own true wireless headsets, which basically integrate the functions belonging to their own brand ecology into the headsets. This means that the functions that A brand headphones can achieve on A brand mobile phones cannot be achieved on B brand mobile phones. This function may be support for specific operations, such as voice assistant or AirPods Pro's fit test, or it may be a difference in listening experience, such as Apple's own exclusive "spatial audio" technology.

Another point is the delay. Some headphones have better delay performance on their own products, such as Apple AirPods Pro or Glory Earplugs 2SE. When playing games and watching videos, this delay difference is enough to mask other performance indicators of headphones.

The sound delay may vary from phone to phone.

In short, with the basic functions of true wireless headsets becoming more and more mature and the gap getting smaller and smaller, the experience difference brought by brand matching between mobile phones and headsets is more noteworthy. Of course, this suggestion only applies to users who don't buy headphones from third-party manufacturers but only buy headphones from their own mobile phone brands.

Wearing headphones is very important, which not only affects comfort, but also affects noise reduction and sound quality (poor sealing leads to bass loss). Most cases of regretting their purchase decision are because they are not as good as expected.

Huawei FreeBuds Pro actively reduces noise, and the true wireless Bluetooth headset is sold at 949 yuan.

According to the data of Strategy Analytics, in 20 19, the annual sales volume of Apple AirPods series reached 60 million. The more headphones are sold, the more critical their shape design is. Because designers have to ensure that a shape is suitable for thousands of people's ears. It is impossible to make headphones that perfectly fit the shape of everyone's ear canal, so it often happens that Zhang San is comfortable to wear and Li Si is uncomfortable to wear the same earphone.

Just like buying shoes, it's best to go to the mall to try on the size yourself. If possible, it's best to try on real wireless headphones in a physical store and find the one that suits your ears best.

Regarding wearing, everyone should also pay attention to the length and firmness of wearing. When you try headphones that are obviously not suitable for you, you can feel them as soon as you put them on, but some headphones will cause discomfort after wearing them for a long time. So it is best to try it on for a long time (30 minutes, 1 hour). People who wear headphones should pay attention to the firmness, because wearing comfortable headphones at rest is not necessarily suitable for running.

In order to stand out from the fierce competition in the real wireless headset market, manufacturers dare not miss it in publicity, and even the most basic and subtle functions should be exposed in a conspicuous position on the product page. Everyone should learn to ignore these factors and ensure that when purchasing headphones, only the important places are concerned.

The first thing that can be ignored is the battery life that almost all headphones will promote. Ignore this point, not because the battery life is not important, but because the battery life of the mainstream brand true wireless headset 202 1 is good enough.

Then the transparent mode. Headphones that support active noise reduction will be equipped with a function commonly called "transparent mode", which will pick up external environmental sounds (conversation, broadcast, traffic) through the built-in microphone, and then amplify these sounds in the headset. Although there are differences in the sound permeability and naturalness (somewhat like the feeling of listening directly without headphones) of different headphones, most people will not notice these differences, even more difficult to identify than the sound quality.

Therefore, it is good to have a transparent mode. It doesn't matter which model is better than which one. In particular, this mode was originally built for noisy environment, and the so-called transparent mode hearing in that environment is useless.

Headphones are a very subjective product. In addition to the wearing mentioned in the article, the same is true of its core-sound quality. The sound quality you like, others may not like it. You think headphones with good sound quality may not satisfy others.

So generally speaking, buying a real wireless headset is divided into two steps. First, filter out the poor products. Second, find the right one among the good products. In this way, the correct purchase decision will naturally come.
