Basic Operations and Screens
Installing the earbuds
If the earbuds do not fit your ears correctly, the noise canceling effect will not
be optimal. To optimize noise canceling and to enjoy better sound quality,
change the earbuds to another size, or adjust the earbud position to fit your
ears comfortably and snugly.
The M size earbuds are attached to the headphones before shipment. If you feel
the M size earbuds do not suit your ears, replace them with the supplied S or L
size earbuds. Confirm the size of the earbuds by checking the color inside.
When you change the earbuds, turn to install them firmly on the headphones
to prevent the earbud from detaching and remaining in your ear.
