About noise canceling

The internal microphone embedded in the
stereo headphones for noise canceling picks
up ambient noise. The IC recorder
generates an antiphase sound wave against
this ambient noise to reduce it. The noise
canceling function can reduce unwanted
ambient noise, especially in a vehicle such
as an airplane, train, bus, etc., allowing you
to enjoy music at a low volume.
P Notes
• If the supplied stereo headphones for noise
canceling are not used properly, the effect of
the noise canceling function may be
degraded. To make the most of the function,
use the correct size earbuds to fit your ears
and insert the stereo headphones for noise
canceling into your ears snugly.
