We have talked about the newly-released Xiaomi Mi Air 2 Pro for myriads of times. And now, it’s the right time to test it and understand whether it deserved our praises.
Xiaomi Mi Air 2 Pro Unpacking
The Xiaomi Mi Air 2 Pro has a black packaging with the earphones photo printed on the front.
On the opposite side, we can find a few eye-catching features of these earphones, including the Qi wireless charging support and built-in Xiao Ai voice commands support.
Once opened, we can find the charging box, which has a black color as well.
Like other Xiaomi products, it has a minimalistic design.
When we open the charging box, we can see the earbuds are not immersed into their hollows like other products from this niche.
Apart from the charging box and earphones, there is also a user manual, a charging cable, and a few pairs of earplugs.
You can see that there is a microphone hole here. This is the front feedback microphone (FF) of the headset.
The microphone hole here is the feedback microphone (FB).
The dual-mic noise reduction combined with feedforward feedback can guarantee the maximum width and depth of noise reduction. Also, it can provide a maximum of 35dB of hybrid noise reduction.
Here are the sensors and vents.
The microphone hole here is the call microphone (MIC).
Xiaomi Mi Air 2 Pro Actual Use
Call out Xiao Ai to search for headphones.
Find the headphones in the list and pair.
After, you will see a pop-up animation.
In the follow-up interface, you can see the rocker for activating the noise reduction mode.
The Xiaomi Mi Air 2 Pro provides 5 pairs of silicone earmuffs (a pair of M models have been pre-installed on the earphones, and the remaining pairs of S, M, L, and XL are in the package).
Though we have head that many users complain of the earphones from falling off from the ears when doing sport, we didn’t experience anything like this.
Because some users reported that the earphones were unstable and slippery, the earplugs fit and other issues, Xiaomi has begun to reissue new earplugs for users who have purchased the Xiaomi Mi Air 2 Pro. Also, the subsequent production of earphone packaging will directly add new earplugs. We are reviewing the new version. In the macro mode, we can see that the surface of the new version of the earbuds on the right is much rougher than the old version on the left, which increases friction.
In fact, when we turn on the noise reduction mode, everything outside becomes silent. We have to admit that Xiaomi has done a great job and it provides a noise cancelation performance similar to flagship models.
Although the firmware 18.104.22.168 update description stated that the wind noise resistance of the Mi Air 2 Pro has been improved, the wind noise of the earphones is still obvious. Moreover, under the circumstances, the earphone will also have a ‘crashing’ wind noise. When wearing a mask for jogging or after exercising, the airflow from the mask rushes toward the earphones, which can also produce wind noise. Even if the breeze blows, the Xiaomi Mi Air 2 Pro has a 50% chance of producing wind noise.
All in all, the current performance in terms of wind noise is average. And we are still waiting for the follow-up optimization update from the Xiaomi headset team.
In terms of sound quality, the Xiaomi Mi Air 2 Pro has too heavy bass. But the mid to high range is slightly insufficient. The sound quality does not sound transparent enough.
It is worth mentioning that NetEase Cloud Music provides adaptive sound effects to the Xiaomi Mi Air 2 Pro.
The Xiaomi Mi Air 2 Pro officially advertises that the headset has a battery life of up to 7 hours without active noise reduction, and up to 28 hours with the charging box. The actual battery life is very good. In our daily use test, even if the active noise reduction is enabled on the headset, a single battery life can reach about 7 hours. Moreover, the charging speed of the Mi Air 2 Pro in the earphone box is very fast.
The official version of the Xiaomi Mi Air 2 Pro does not currently support the LHDC protocol. So we have not experienced the 100ms delay advertised before the release.
We used Latency Test to perform a delay test on the Mi Air 2 Pro. The test principle of this software is to control the Bluetooth headset to emit a sound and start timing at the same time. When the microphone of the smartphone receives this sound, the timing will end. Then, the average delay time will be given after multiple measurements.
Through the principle, we know that the delay of the Bluetooth headset tested by the software is composed of two parts: the delay of the smartphone + the actual delay of the headset. It cannot represent the delay of the Bluetooth headset alone. But the measured total delay value is subjectively felt when we actually use the headset. The delay is consistent.
The test phone we used is the Redmi K30 Pro. The phone delay is 65ms. And the Bluetooth headset test delay (smartphone delay + Bluetooth headset actual delay) is 341ms. We can conclude that the actual delay of the Xiaomi Mi Air 2 Pro is about 276ms, which is far from the level previously stated in the promotion of low delay.
Functions and control
After the headset is connected, there will be a pop-up window of Xiao Ai’s Bluetooth headset control in the notification bar. Click the control button in the notification bar to jump to the Xiao Ai App for the next step.
Since Xiao Ai’s app is often killed by MIUI in the background, the pop-up window is often not displayed. Sometimes it may even appear that the smartphone and earphone have been connected to play music. But the Bluetooth headset device management in Xiao Ai app shows that the earphone is not connected. Sometimes even the headset cannot be connected, even when you click the connect button.
It only takes about 1s to switch the noise reduction function of the earphones. It only takes about 1s to wait for the switching sound on the Xiao Ai app. And it takes 4s to touch and hold on the earphone (long press the earphone 3s + switch sound 1s).
At present, the sound volume of the Xiaomi Mi Air 2 Pro earphones is too loud and unadjustable. We hope Xiaomi will optimize this in the future.
The Mi Air 2 Pro supports the custom function of double-tap earphones, voice hot words and smart scene functions. The sensitivity of double-tap headphones is much higher than that of the Mi Air 2s, and the success rate is basically 100%.
When the earphones are connected to the Xiao Ai app in the morning and evening, they will broadcast weather information, music and songs for you, and perform custom operations.
Before testing this device, we have heard from many users that the Xiaomi Mi Air 2 Pro feels like a ‘semi-finished product’ released in a hurry. They said these earphones do not support low latency, wind noise issues need to be resolved, the headphone pop-up window is not fully adapted… But when reviewing, we understand that none of these complaints are true. However, we should also say that these earphones are not worth of the price they come at (649 yuan ($97)). For this price tag, you can get your hands on a worthier model, undoubtedly.
