So after having made fun of people for “wearing toothbrushes”, I finally came to buy such headphones for myself.
Having used non-true wireless Bluetooth headphones before I was curious what the usability advantage would feel like.
Here I went for the Xiaomi AirDots Pro 2 aka Air2 which I could grab for 399 Yuan which is about 51€, which seems like the right price-point for this kind of accessoire.
Keep in mind that the built-in battery only survives so many charging cycles and once it dies you can throw them away.
The initial feeling of using true wireless headphones is surprisingly relieving – there is simply no cord to untangle or to be aware of while wearing.
This is especially true during phone calls, where one needs to keep the microphone aligned.
The downside is that the headphones are too small to accommodate any buttons for volume and playback control.
The Air 2 kind of make up for it by automatically connecting to your phone once you put them on and by automatically pausing the music when you put one out of the ear. This is achieved by a built-in brightness sensor.
Furthermore you have double-tap actions, which default to play/ pause on the right headphone and launching the voice assistant (e.g. Google Assistant) on the left headphone.
The battery life is stated with 4 hours per-charge with 2 extra charges in the case. I could confirm those on a long distance flight.
Compared to the Airpods 2
Looking at the feature-list above or simply at the images, the similarity to the Apple Airpods is apparent.
Out of curiosity I borrowed some from friend for comparison. The most important point is probably sound quality. Here we found the two virtually in-distinguishable. But keep in mind that we only did a quick test and did not use them extensively.
The second point is likely the form. Here, both earphones have the same ear-part and only differ by the shaft. So if one fits your ear, so should the other.
The shaft however is considerably wider on the Airdots. This is less apparent when viewed from the side as the thickness is similar.
For me, the more important difference is being able to control the headphones from my Android smartphone. This is currently not possible with the Airpods, while there is some way for the Airdots;
Companion app & Software integration
To control the earphones, you have to sideload the Xiao Ai Lite App. The main purpose of it is to provide the Xiaomi voice assistant and the Air2 options likely just ended up there as they offer an always-on assistant integration just like the Airpods.
It handles firmware updates and allows you to configure the douple-tap action per earphone as well as displaying the charging status of the earphones and the case.
The downside is that the app is currently only available in Chinese and consequently the voice assistant only works with Chinese.

I tried out some voice commands via google translate and everything works as it should. However if you are not fluent in chinese it is far from practical. Most people should disable the assistant in the settings to avoid accidentally triggering it.
If you own a Xiaomi Phone you get those settings via MIUI as well as a slightly faster pairing process. Here, instead of pressing the pairing button, you only have to open the case while holding it near your phone.
A serious advantage of Xiomi/ Huawei phones is the availability of the LHDC Bluetooth Codec which offers a superior bandwidth and latency.
While I am fine with the bandwidth provided by AAC when listening to music, there is still a noticeable and annoying delay when watching videos and playing games.
Active Noise Cancellation
The firmware upgrade to v220.127.116.11 significantly improved the active noise cancellation and thus general sound quality.
There is a very noticeable noise reduction compared to v18.104.22.168 – especially in the lower frequencies; things like your footsteps get filtered out. Higher frequencies like car motor sounds are still perceivable though. This is however a good compromise for me.
