Ambient Sound Function
Noise canceling function
You will hear an audio guidance when the function is switched.
Using the ambient sound function allows you to hear your surrounding sounds.
Using the noise canceling function mainly helps to reduce ambient noises such as noise in a vehicle and noise from air conditioners in a room.
Even when the ambient sound function is used, you may not be able to hear surrounding sounds depending on the volume of the music.
The noise canceling function is effective for low-pitched sounds such as noise in a vehicle and noise from air conditioners in a room but less effective for relatively high-pitched sounds such as announcements, conversations and bells in vehicles.
When the remaining battery power becomes low, you will hear an audio notification through the headphones.
We do not guarantee all operations of the BLUETOOTH device.
