Notes:

- Sleep A20 bluetooth earbuds does not have an ANC feature.

- Smart Volume: In Sleep mode, the mic of your phone will detect changes in ambient noise. When there is a consistent increase or decrease in volume, the audio volume will dynamically adjust according to external noise changes, providing a noise masking effect that is more adaptive to dynamic environments. This feature is only effective in Sleep mode.

- It is necessary to ensure that the earbuds are connected to the smartphone, and the app must continue to be active (do not manually close the app).

- The earbuds themselves do not have microphones; they rely on the smartphone's microphone to monitor ambient noise levels (only detecting changes in environmental volume, without recording or recognizing the content of the sound in any form).

- This feature requires more than half an hour of use before a corresponding report will appear (you will see a one-time monitoring result either when you manually turn off the feature or before the next use).

- This feature provides a maximum volume limit of 65dB. The earbud volume will not continuously change with the external environment's volume level (in compliance with the World Health Organization's recommendations for hearing protection).
