What to do if the sound quality/noise cancellation effect of the Xiaomi OpenWear Stereo is poor?

The noise cancellation experience of open-ear earphones is not as good as that of in-ear and semi-ear earphones, so it is currently only a laboratory exploration function. You can experience it in a relatively quiet environment such as an office or a study room with mild noise. You are welcome to provide more valuable suggestions for this function. The noise cancellation function is turned off by default. It is also turned off by default every time the earphones are put back into the charging case and then taken out again. If you need to use it, please turn it on again.
Please refer to the following steps:
1. Download the [Xiaomi Earbuds] APP and connect;
2. Turn on the [Noise cancellation] switch. You can experience noise cancellation after turning it on;
3. You can also control it through gestures, and adjust the default function of the [Press and hold left/right earphone] to the noise cancellation switch, so that you can turn on or off noise cancellation by touching the earphones.
