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

Press and hold (for about 2 seconds) the multifunction button on the L (left) side headphone.

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

	Depending on the volume of the music being played back, the surrounding sounds may be difficult to hear. 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.
