Redmi AirDots true wireless Bluetooth headset review


As this month’s “Best Chop Month of the Year”, I believe that many small partners have started their favorite products during this period. In fact, the development of Double Eleven is very mature now, and various e-commerce companies have also listed the real-time sales rankings of various commodities during Double 11 this year. Convenient for consumers to find more suitable products. In it, we also found a strange phenomenon. In the real-time list, Xiaomi Redmi AirDots true wireless Bluetooth headset, this product often dominates the “sales” and “sales” of the digital list of headphones. If you say The sales list is due to its affordable price (99.9 yuan), so it is a bit scary to rank ahead of other 4-digit headphones in the sales list.

In fact, with the removal of the 3.5 headphone jack from most mobile phones launched by mobile phone manufacturers, Bluetooth headsets can be regarded as a new solution. There is no need to plug in an adapter or take care of difficult earphone cables. To a certain extent, On the basis of ensuring the use experience (sound quality, delay), the Bluetooth headset will be more labor-saving. So Xiaomi Redmi AirDots true wireless Bluetooth headset as such an explosive headset in Double Eleven, in addition to its affordable price, what else attracts consumers? For this we also bought this headset and tested it.

Appearance design: compact and simple aesthetics

The product includes earphone box, earphone, instruction manual, two different size earphones (plus S, M, L specifications), and it is not equipped with a charging data cable. First of all, in the appearance part, it belongs to a simple design. The overall size of the earphone box is 62x42x22mm. It is still very light on the body. The front is printed with the Redmi brand logo, and the interface has a Mirco USB interface. It should be mentioned that although the material of the box is plastic (after all, the price is compressed to 99.9 yuan), but from the look and feel, there is a bit of matte feeling, and it does not give people a cheap feeling because of the use of plastic materials.

The body of the headset is also made of plastic and has a matte feel. The weight of a single headset is 4.1g and the size is 23x15x12mm. This weight and volume are relatively lightweight, and there is not a lot of load when wearing it. Wear the headset It can be said that it is the same as not feeling. The overall shape of the headset is like a “big piece of Yida Gum”, and its appearance looks pretty good.

On the inside of the earphones, the letters L and R are convenient for users to distinguish between left and right wearing. Below the logo are the charging contacts used by the earphones to connect the earphone box for charging. In general, the design of Xiaomi’s Redmi AirDots true wireless Bluetooth headset is still acceptable, whether it is the headset box or the headset, and it has not shrunk in the design due to the low price.

Function and control logic: call voice assistant for convenience

After talking about the appearance, let ’s talk about what are the characteristics of this Xiaomi Redmi AirDots true wireless Bluetooth headset in actual use. Clicking the headset button once in the control logic of the headset can achieve “answer / hang up”, “pause / play” Music “; you can refuse to answer the call by pressing and holding the headset button for about 1 second.

In addition, I think the best way to use it is to wake up the voice assistant. For example, you can call siri, Google Voice Assistant, and Xiao Ai with two double clicks. (The voice assistant for other brands of mobile phones is not available.) Can complete “send WeChat to someone”, “route to a certain place”, “find mobile phone”, “countdown front selfie” and other operations, it is still very convenient to use. In actual use, the experience it brings is also good. The voice assistant responds quickly while the voice recognition is high. It can quickly and correctly recognize instructions and implement operations in quiet or slightly noisy situations.

It is also more convenient to use. It can be turned on and off without manual operation. It will automatically turn off when you put it in the headset box. When you remove the headset from the headset box, it will automatically turn on. Fast! It should be connected in about two to three seconds. And it supports the single ear mode, and you only need to take out a headset to operate it with one ear.

Charging and endurance: two hours and 45 minutes

The charging speed and endurance of a Bluetooth headset are also very important. The battery capacity of this headset box is 300mAh, and the battery capacity of a single headset is 40mAh. It should be mentioned that the charging port uses the Mirco USB interface and is not equipped with a charging cable. In addition, the current mobile phones are basically lighting and Type-C. For most people, it may only be a price increase when buying. A Xiaomi 2-in-1 (Mirco USB / Type-C) charging cable.

After we bought the headset, we first performed an extreme endurance test with the battery fully charged. The mobile phone participating in the test was Xiaomi 9 SE (own brother). The test method is that the mobile phone is connected to headphones and plays music at 100% volume, and the playback starts from a fully charged state, and the endurance of the mobile phone is 165 minutes (2 hours and 45 minutes). According to this result, listening to songs for four hours under daily normal use is completely achievable, and it also conforms to the official rhetoric.

The official charging test of Xiaomi’s Bluetooth headset shows that it takes 1 hour and 30 minutes to charge the headset; it takes 2 hours to charge the charging case. In the charging test, we also split the test into two types: “headphone box to charge the headset” and “connect the power adapter to charge the headphone box and the headset” for testing.

First, I used up the earphones’ power (automatic shutdown), and then put them into the earphone box to charge. The whole charging process took about 72 minutes (1 hour and 12 minutes). When the headset and the headset box are empty, the charging takes about 156 minutes (2 hours and 36 minutes). It is worth mentioning that the official headset charging time is two hours and the headset charging time is one and a half hours. It should take three and a half hours to fully charge the two. Then according to our test results, it only takes about two and a half hours to charge the headset and the headset box at the same time. The actual measured time in the charging speed is shorter than the official rhetoric. This is also because the power connected is different because the adapter is connected.

In general, the battery life and charging ability of Redmi AirDots true wireless Bluetooth headsets are not good or bad. It is counted as four hours of normal use of the headset, so it can be charged about 3 times with the headset box for a total of 12 hours. Battery life (only for listening to music, other applications may be slightly different), it can be said that good or bad depends entirely on the needs of the user, but for people like me who use the frequency of the headset more often, daily use It’s enough.

Practical experience: sound quality exceeds expectations

In fact, it has been a week since I started using this headset, and there are both when it is really scented and when it is rolled over. First of all, in terms of battery life, headphones are used basically every day, but the battery is charged only once a week, which is very durable. Secondly, I also turned over the car when I was using it. Once when the headset was almost empty, I was listening to songs with the headset. Occasionally, there were intermittent stutters, and it recovered after being fully charged. There were still some small defects. For a Bluetooth headset, the sound delay and sound quality performance are still very important. I have tested it during almost a week of use.

In the network delay part, the performance of this headset is still good. In the test, we used the game “Peace Elite” for testing. As we expected before the test, when you put on the headset, you will be able to listen to the footsteps in the game and the car. The synchronization of sounds and gunshots is very good. It can be said that there is a delay with the ears. After all, Bluetooth 5.0 is used. The delay control is still deadly.

In terms of sound quality, before the test started, I said, “What kind of sound quality does this headset require?” But in the test, it performed well (only for headphones within a hundred yuan), maybe It is because the 7.2mm dynamic coil drive unit is used, which still gives people a certain degree of recognition in the low-frequency performance. It is known that this is not just a loud earphone. It has a relatively prominent performance compared to other headphones of the same price. Latent sensation, while in the high-frequency part is quite satisfactory, but still outstanding, unlike a headset within a hundred yuan, by the way, a noise reduction function, said to use DSP intelligent noise reduction, but in the process of use from As far as my subjective experience is concerned, first of all, the effect of noise reduction is still there. You can effectively avoid noise when you take subway buses outside, but I think noise reduction may have little to do with “DSP intelligent noise reduction”. Most are caused by in-ear earplugs.
