Using the noise controls mode
Introduction
There are two noise control modes: active noise cancelling and ambient sound mode.
Activate the active noise cancelling feature to block out the external sounds around you. Use
it when you want to avoid distractions, such as when listening to music. Conversely, activate
the ambient sound mode to hear your surroundings clearly, so you can quickly detect any
potentially dangerous situations or hear another person’s voice during a conversation.
If the microphone (the outer microphone while wearing the earbuds) and its area are
covered completely, feedback may occur when launching the active noise cancelling
feature.
You can only activate the noise controls mode when wearing both earbuds in your ears.
