The word "noise reduction" can be said tobe one of the most important functions when people buy a headphone product.Although the difference in sound quality is not obvious to most consumers, thefeeling of noise reduction is very intuitive and obvious, so this has becomethe direction of many brand product planning, as we will say today. Milletcollar noise reduction Bluetooth headset.



First of all, it is not the first time thatXiaomi has seen noise reduction products on the earphone products. The previouscable version of the noise canceling headphones has also been recognized bymany users. But now it has entered the era of full wireless, wired noisereduction is a bit cumbersome, so the emergence of wireless noise reductionheadphones is also just the need for product planning.

 

The reason why Xiaomi's first wirelessnoise canceling headphones chose the neck-mounted design is because the cost ofthe transmission, noise reduction and storage of the split Bluetooth headset ishigh, which cannot meet the pricing strategy of Xiaomi; on the other hand, thehead-mounted type Headphones can't meet the needs of all users' usagescenarios, so a comprehensive view of neck-mounted is still a good solution.

 

First of all, look at the appearance part.The Xiaomi collar noise-reducing Bluetooth earphone is still very kind in termsof the overall material selection. The neck-hanging part adopts theskin-friendly material of soft rubber, and the ductility of the soft rubbermaterial can adapt to the neck shape of different users. At the same time, theskin-friendly material can be in good contact with the skin during daily wear,even if sweating does not affect the wearing comfort.




The front end of the earphone is wrapped ina metal case. This part is the location that we often touch in our daily life.The metal case increases the durability of its use. It also provides bettertactile feedback to the fingers during operation, and the metal material alsoproduces a certain weight, which improves the stability of the wearing prefixin daily use. However, metal materials will be easier to retain fingerprints, andobsessive-compulsive disorder may be wiped out.

 





On the front metal casing, there areseveral operation buttons, the left part is the conventional switch, the volume+-, and the Type-C charging interface is also placed on the inner side of theleft metal area, and the normal charging is also compared. Convenience. On theright side, there is only one Hybird noise reduction button to control thetwo-stage noise reduction function of the Xiaomi collar noise-reducingBluetooth headset.


As for the main body of the earphone,careful observation can be found that the sound hole portion of the earphone issimilar to an elliptical shape, similar to the shape of the silicone plug. Thetwo earphones can also be attracted to each other through the magnets on theback, and they will not arbitrarily sway when not wearing them.

 

Noise reduction/hearing

 

The Xiaomi Collar Noise Reduction BluetoothHeadset uses Hybrid Hybrid Digital Active Noise Reduction technology, which isa combination of feed-forward noise reduction and feedback noise reduction. Thetechnology used in the noise canceling headphones combines to form the Hybridnoise reduction technology.

 

Hybird noise reduction captures thesurrounding ambient noise through two mics before and after, and matches theexternal sound waves by the algorithm and performs reverse sound cancellationto achieve the effect of environmental noise. But this noise reduction can onlyeliminate the normal environmental noise, such as the sound of airplanes,buses, and subways. However, the Xiaomi collar noise-reducing Bluetooth headsethas a relatively large ear pressure after the noise reduction function isturned on, and a long-term wear will have a slight swelling feeling. If youcare about this point, you should be cautious.

 

After the noise reduction is turned onseparately, the Xiaomi collar Bluetooth noise canceling headphones are notobvious for the vocal and keyboard sound cancellation. But the music soundafter the music is turned on will cover up the outside world, so this does notneed to care too much in daily use.

 

During the period of using the Xiaomicollar noise-reducing Bluetooth headset, I also experienced three major noisereduction environments, namely subway, bus and airplane. In terms of actualexperience, after the highest level of noise reduction is played, the noiseelimination ratio of public transportation, subway, and airplane is about 95%,85%, and 70%, and after a long period of wearing, the focus is mainly on music.Up, so the final ambient sound does not cause too much interference to thesense of hearing.

 

Endurance is also believed to be a part ofmany users' concerns, because the noise reduction itself must capture theexternal ambient sound and form a reverse impact, so the sensor is always working,and the power consumption is relatively large. From my use of a few days, I canbasically handle a minimum of 10 hours after a full charge, and this is aconservative number, so if you only wear headphones to go to work every day,then there is no charge every week. possible.

 

In the listening part, the overall soundquality of the Xiaomi collar noise-reducing Bluetooth earphone can only beregarded as a general level. There will be obvious noise floor when the song isplayed, and there is no excessive tendency in the sound color. It belongs tothe more mediocre type. . However, when listening to songs with richer rock ormusical instruments, the overall scene will be slightly confusing, and thegeneral pop songs will still be no problem.



After a few days of use, my score on theXiaomi collar noise-reducing Bluetooth headset is 80 points. The overall weightcontrol is very good, and the skin-friendly material and the soft rubber archave basically no wear on the daily wear. burden. And the noise-reducingearphone millet in the 400-500 price range still has a very high costperformance. Although the effect is not as good as that of Bose and Sony, theadvantage lies in the lower price, so the noise reduction effect and soundquality are also insufficient. It becomes understandable.
