I did the review of Mi Air 2 a long time back that time I got that it from China and now the same has been launched in India as Mi True Wireless Earphones 2 priced at Rs. 3,999.
There is no different among the Mi True Wireless Earphones 2 and the Mi Air 2, however the box packing is different you can check the same in the video below.
The box pack content is the same.
This is true bluetooth earbuds, comes with a charging case and the earbuds (with TWS feature), which means you can use single earbuds if need be.
Mi True Wireless Earphones 2 is using 14.2mm dynamic drivers, bluetooth 5.0, ENC and LHDC for lossless audio experience.
The unique thing about these earbuds considering the price is that it comes with wear sensor, you put the earbuds in your ear the audio / video will continue playing and when you remove the earbuds the audio / video will pause.
Now this feature you usually would get in a premium earphones. Apart from this the earbuds come with touch control to control media and to activate voice assistant.
Talking about the performance I did not notice any changes both the Mi Air 2 and the Mi True Wireless Earphones 2 audio quality was the same. PUBG play was better and in sync using Earphones 2.
Mic quality is also pretty impressive.
