Notes
If the supplied headphones 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 headphones into your ears snugly (
page 8).
The Noise Canceling function mainly reduces the ambient noise in the low frequency
bands and has no effect against the ambient noise in the high frequency bands. It has no
effect on some sounds.
Do not cover the microphone part of the headphones with your hands, etc., otherwise
the Noise Canceling function may not work.
