For voice calls, the earbuds work great and block ambient noise without creating any in-ear vacuum that active noise cancellation earphones do. The earbuds support in-ear detection through built-in sensors and pause the music as soon as you take the earbuds off and resume it when you put them back on.
While everything works fine, the touch controls seem out of the equation here. The earbuds do not recognise touch often, and the gestures are confusing. For example, you must tap twice and thrice for play/pause, skip track, enable Thru Mode, or call a voice assistant. All this seems like a task. Thankfully, the Amazfit app lets you customise these controls and one can set them based on personal preferences.
