Hear-through function
This function allows you to hear surrounding sound via the built-in microphone while you listen to music.
1
Touch and hold (about 2 seconds) the touch sensor on the L (left) side headphone.
With every long touch (about 2 seconds), the voice guidance will play the message “Hear-through” or
“Hear-through off”, and the hear-through function will be turned on/off.
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 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.
Equalizer function
Choose from three sound quality options.
