Active Noise Cancellation

Under the Active Noise Cancellation (ANC) Function of the Xiaomi headphones is an active noise cancellation by anti-sound. about MEMS microphones in the driver housings, the ambient noise is measured and compensated by an opposite polarity signal. Mainly noise from lower frequencies is compensated.

The best way to describe function is with a slight pressure on the ears. Of course, not all outside noise will be hidden. Noises such as voices appear quieter and dull. City sounds, however, are almost completely filtered.

In combination with the already noise-insulating construction Xiaomi Piston ANC, the headphone's Active Noise Cancellation feature is a perfect complement to listen to undisturbed music. The sound quality is not affected by the active noise cancellation. When the ANC is switched on, only a slight background noise is noticeable, but it is so small that it completely goes down with the music playback.

Wired remote control and microphone

Unfortunately, the wired remote does not work as described in the manual. Over a total of 3 buttons can be the Control music playback, as well as accept and reject calls. With the middle control button music could only be paused and continued in the test, as well as left Accept or reject calls, However, according to the instruction manual, it should be a multifunctional key that can be used to double-click or triple-click to play the previous or next track. Even with one Xiaomi Mi6 this feature was not feasible! The other two buttons are for the Volume Control and can be reprogrammed to track selection with a Xiaomi smartphone.

The recording quality of the microphone responsible for calls. Due to its noise-suppressing function, the recording quality is extremely clear and free of noise. However, you should keep the microphone close to the mouth, because even by a short distance, the recording volume is significantly reduced.


By the ergonomic design The Xiaomi ANC headphones offer excellent wearing comfort. The oval-shaped sound tubes and the additional silicone saver, the in-ear sits without much pressure, but still safe in the ear.


Xiaomi explicitly mentions that the in-ear - especially the ANC function - is only compatible with a few Xiaomi top models. Among them are currently the models Xiaomi Mi6, Mi5S, Mi5S Plus, Mi5, Mi Mix and Mi Note 2. The Mi 4C and Mi 4S models have limited compatibility. Not compatible are the Xiaomi Mi5C and the Redmi Pro models.

The test showed, however, that the Xiaomi ANC in-ear is also compatible with smartphone models from other manufacturers. With the tested smartphones ments Apollo, UMIDIGI Z Pro as well as Elephone P9000 There were no problems with the music playback and the Active Noise Cancellation worked perfectly. In order for the headphone to work properly, it is probably sufficient to support the "USB Audio Device Class 3.0" standard.
