The noise cancellation cannot be turned on when the earphone is used with one ear; or after wearing the earphone to turn on the noise cancellation, removing the single ear will automatically switch to the transparency mode.

Hello, in the early stage of product design, we considered that different users may feel uncomfortable when using the monaural noise cancellation function. In order to ensure the consistency of binaural noise cancellation, it is recommended that you use it with both ears to experience a good noise reduction effect. It is recommended that you wear it on both ears.
