Yamaha TW-E7B Noise-Canceling True Wireless In-Ear Headphones (White) - Manual (Page 27)

Playing back sound according to your surroundings
Enabling AMBIENT SOUND makes it easier to hear the sounds around you, such as announcements made on
public transportation, the sounds of passing cars and so on.
Also, when you enable ADVANCED ANC, the earbuds reduce only the external noise while maintaining
playback sound quality, eliminating the need to turn the volume up too high.

While the AMBIENT SOUND feature makes it easier to hear sounds around you, it does not guarantee that you will be able to hear
everything. You may be unable to hear ambient sounds if you’ve turned up the volume of the audio, or in certain situations.
( You can also set the AMBIENT SOUND and ADVANCED ANC features with the Headphone Control app. The settings are as follows.
(
AMBIENT SOUND: the sounds around you will be mixed together with the playback sound.
(
ADVANCED ANC: This feature reduces only the external noise while maintaining playback sound quality, so that you don’t need
to turn the volume up too high.
(
OFF (default setting): this is normal playback mode.
( Depending on the type of sound you are playing back and what is going on around you, the ambient sound may not be so easy to
hear. In this case, pause the playback.
( Do not cover the earbuds with your hand. If your hand is covering the earbuds, AMBIENT SOUND and ADVANCED ANC will not work
properly, and you may hear noise.
