INSERTING THE EARPHONES

WEARING THE EARPHONES

CHOOSING AN EARPHONE SLEEVE

Your earphones come with a selection of sleeves. Make sure the sleeve you
use is easy to insert into your ear, fits comfortably, and is easy to remove from
your ear.

Warning: Do not push the earphone sleeve
beyond the ear canal opening.
Make sure that the sleeve completely covers
the earphone nozzle. If any part of the
nozzle is exposed, the sleeve is not properly
installed.

When using the foam sleeves, compress the sleeve between
your fingers before inserting it into the ear canal. Hold the
earphone in place for about ten seconds while the foam
expands and creates a tight seal.

Triple-Flange Sleeves (Optional Accessory)

scissors to carefully trim the nozzle to the desired length.
