• The volume of the product differs depending on if the noise­cancelling function is on or off.

• The hear-through mode of the product allows you to hear the
sounds around you through the built-in microphone while you are
wearing the product. 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.

• When the hear-through mode is on, the volume of music, etc., is
automatically reduced so the product can assimilate the ambient
noise. This reduction in volume is normal; the product is not
malfunctioning.

• Depending on your surroundings, the surrounding sounds may be
difficult to hear even when using the product’s hear-through
mode. Do not use the product in places that could be dangerous
when you cannot hear the surrounding sounds, such as places
with heavy traffic.

• Operate the touch sensor with one finger. Operating with a
sharp-tipped object, such as a ballpoint pen or pencil, may not
only result in incorrect operation, but could also damage or break
the touch sensor.

• Do not tap (touch) the touch sensor with the very tip of your
finger. Doing so may cause your fingernail to break.

• If the product does not operate at all or as intended when tapped,
check to make sure that your other fingers, parts of your hand, or
clothing are not in contact with the product when tapping. Also,
the product may not operate correctly if you are wearing gloves or
if your fingertips are dry.

• The product may not operate correctly if the touch sensor is dirty
from sweat. Remove any dirt before operating the product.

About the active noise-cancelling function

The product is designed to use its built-in microphone to pick up noise from the surrounding environment (noise from
vehicles, noise from air conditioners, etc.) and to cancel out that noise by producing sounds in negative phase. This
results in a reduction in the sounds in your environment.

• The product’s noise-cancelling function mainly reduces noises of 300 Hz or lower. Because of this, it has almost no
effect on noises above that frequency (ringtones, speaking voices, etc.).

• Not all sounds are cancelled.

• Depending on the type of noise (or in quiet locations), you may not notice the noise-cancelling effect.

• There is a “humming” sound when you turn on the noise-cancelling function. This is the sound of the noise-cancelling
function operating; it is not a malfunction.
