31.Q:How does Mi True Wireless Earphones in-ear detection come true?

A: There is an infrared optical sensor on the left and right side of the Air headset. When wearing the headset， the infrared optical sensor will be blocked. The headset is judged to be wearing the headset， and the ear will send a "thrum" sound.When the earphone is removed， the infrared optical sensor detects that there is no occlusion， and the earphone is judged to have removed the earphone. At this time， the earphone indicator will be on for 5 seconds.

Based on this working principle， when the infrared optical sensor is blocked by fingers， clothes， etc. when the finger， clothes， etc.， is blocked， the ear will misinterpret as wearing the headset or taking off the headset.

If the user happens to double-click/long-press the touch button， it may play music/pause music/start the voice assistant/turn on the active noise reduction/turn off the active noise reduction.

 

33.Q: Why is the sound worse when playing games?

A: Because A2DP protocol is activated when you listen to music.When playing the game， the game APP starts the HFP calling protocol， the HFP protocol audio bandwidth is relatively narrow， the sound quality is slightly worse.
