Gearbest Tech
[Gearbest Review]2023 seems to be an unusual year. It can not only be called the first year of AI large models, the first year of new energy vehicle involution, but also the first year of open-back (OWS) headphones. In this year, OWS earphones took advantage of the strong demand for secondary earphones. Some headphone brands entered the market one after another and launched many excellent OWS earphones. As a result, open-back earphones grew by 130.2% year-on-year in the Chinese market and gained consumer trust. recognition and love.
Faced with such an attractive blue ocean, Xiaomi, known as the “Xiaomi Grocery Store” and “Price Butcher”, will naturally not miss this incremental market. Therefore, at the new product launch conference on April 10, Xiaomi's first open-back headphones Officially meet with you, the initial price is 649 yuanliving up to the reputation of price butcher.
One-piece shape, stable and comfortable
In terms of appearance, the charging compartment of Xiaomi open-back headphones does not adopt the currently more common rounded square design, but adopts a flat oval shape similar to pebbles, with the xiaomi logo in the middle. The upper and lower parts are separated by a silver chrome trim strip, and the tail is the currently common Type-C charging socket.
After opening the charging compartment, what comes into view is the headset body. The headset as a whole can be divided into two parts. Among them, the combination of NCVM high-gloss decorative parts and laser-engraved matte logo highlights the high-end and refined feel of the headphones. The parts that come into contact with the ears are all designed with spray-on touch paint for a more comfortable fit.
It is worth mentioning that Xiaomi’s open-back headphones adopt a smooth one-piece earhook shape. This design allows the headphones to follow the curve of the ear, thereby conforming to the ergonomic design and making the user comfortable and stable when wearing. And the main body of the earphones adopts a stacking and compression assembly process, which is compact and does not stretch the ears.
In terms of ear hooks, Xiaomi's open-back headphones are made of skin-friendly liquid silicone material, which is soft and skin-friendly when used to fit, thus preventing users from earache caused by long-term wearing. In addition, in order to ensure the firmness of wearing, the ear hooks are made of flexible metal titanium wire, which has a resilience of 5,000 folds and can fit the ears firmly. Lose. And in order to create a better wearing experience for people who wear glasses, this headset adopts a slimmer design at the earhook.
Directional anti-sound leakage system, personal privacy is guaranteed
Normally, when the volume is turned up to a certain level, no matter what kind of headphones it is, the people next to it can still hear the sound. This is mainly caused by the reflection of the sound. This is true for in-ear headphones, and even more so for open-back headphones. In order to solve this problem, Xiaomi open-back headphones use directional anti-sound leakage technology.
This technology uses a newly added φ10mm anti-leakage unit, combined with the 12×17mm unit front and rear cavity sound guide holes to form a dipole, so that when the earphones play sound, they can emit offset sound waves in the opposite direction to offset the leakage, thereby Improve the privacy of calls, ensure no sound leakage in close-range scenes, and eliminate the possibility of privacy leakage. It is worth mentioning that this technology has also received measurement certification from the China Institute of Metrology.
After actual testing, in an office environment with constant keyboard sounds, turning the volume up to about 60% can isolate the surrounding environmental sounds. And the sound from the headphones will not be heard from the surroundings at the same time. In addition, Xiaomi's new independent sound leakage-proof system can also intelligently identify the size of ambient sounds in close-range scenes and adaptively adjust the headphone volume to further prevent sound leakage.
The bass is powerful and the high frequencies are well-defined
In the author's opinion, the fundamental mission of a headset is to spread sound, so the sound quality is the basic requirement for evaluating a headset. Xiaomi's open-back headphones use a customized 17*12mm runway-type unit. This design can make the space utilization of the cavity higher, and the effective radiation volume is larger and more linear than ordinary units of the same area. . Coupled with the supporting sound unit, the phase of the sound wave can be more precise and the sound reproduction is better. The super linear unit can make the sound distortion smaller and louder.
In terms of unit material, the PU flexible suspension used by Xiaomi open-back headphones is a lightweight polymer material that can reduce sound distortion, increase amplitude, and make the bass of the headphones more powerful. The material of the central dome is made of diamond-like carbon. This material has ultra-high hardness, comparable to natural diamonds. Its advantages are high sensitivity, fast transient response, and the ability to accurately restore sounds. In other aspects, Xiaomi's first open-back headphones also support LHDC high-end encoding, with up to 96KHz and Hi-Res gold label certification and QQ Music premium sound quality dual certification.
During the few days I tried it, the most obvious feeling is that the sound is clear, transparent, and crisp. The bass is surging and full of details, and the mid-to-high frequencies are detailed. Of course, if you want to get the same feeling as the author, you still need to use it in a quieter scene. After all, this is an open-back headset that is not in the ear.
In addition, thanks to the support of Xiaomi ThePaper OS ecosystem, Xiaomi open headphones support functions such as pop-up quick connection, multi-device transfer, audio sharing, and one-click photography.

The price is low but the quality is not low. The brand-new independent anti-leakage system, super-linear sound unit and long-lasting, stable and comfortable wearing experience make this headset shine.
