Ambience control

The product includes an ambience control function for switching between the noise-cancelling function and hear-through function. The functions can be switched from OFF (default), to hear-through, or noise-cancelling.

Function	Description
Noise-cancelling function	The microphone built into the product detects ambient noise and outputs a sound-cancelling signal to effectively reduce noise.
Hear-through function	This function allows you to hear surrounding sound via the built-in microphone while you listen to music.

1. Press and hold (about one second) the multifunction button on the L (left) side headphone and release your finger when you hear the confirmation sound.

   The functions can be switched from OFF (default), to hear-through, or noise-cancelling.

	The ambience control cannot be used during a call.

Occasionally it may be difficult to hear surrounding sound depending on the volume of the music, etc. that you are playing. In this case, turn down the volume of the music. Depending on your surroundings, the ambient sounds may be difficult to hear even when using the product’s hear-through function. Do not use the product in places that are dangerous if you cannot hear the surrounding sounds, such as places with heavy traffic. When the hear-through function is turned ON, do not cover the microphone with your hand. If you do so, a loud sound (howling) will be emitted, and it may adversely affect your hearing ability.
