INSERTING THE EARPHONES
If the earphone seems to be lacking in low frequency response (bass), check
the tightness of the seal between the earphone and your ear, or try one of the
other sleeve options.
Warning: Do not push the earphone sleeve beyond the ear canal opening.
WEARING THE EARPHONES
Three popular methods for wearing the earphones are illustrated below.
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, ts comfortably, and is easy to remove from
your ear.
CLEANING THE EARPHONE NOZZLE
If the nozzle of your earphone is blocked, clean the nozzle using the supplied
wax removal loop.

Yellow and Black Foam Sleeves
When using the foam sleeves, compress the sleeve between
your ngers 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. Black foams come in small,
medium and large sizes.
Note: Carefully slide sleeve over earphone nozzle barb for a secure grip.
To change earphone sleeve, twist and pull sleeve to remove it from the nozzle.
Push new sleeve onto nozzle until you feel it slide completely over barb. If any part of
the nozzle is exposed, sleeve is not properly installed. Replace sleeves if they do not
grip the nozzle tightly
