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.

To change earphone sleeve, twist and pull sleeve to remove it from the nozzle.

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.

Soft Flex Sleeves

In small, medium, and large sizes. Made from pliable rubber.

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.

Triple-Flange Sleeves

If desired, the sleeve nozzle may be shortened. Use sharp
scissors to carefully trim the nozzle to the desired length.

Note: Carefully slide sleeve over earphone nozzle barb for a secure grip.

Tighten the cable and take up slack by raising the cable sleeve .

CLEANING THE EARPHONE NOZZLE

If the nozzle of your earphone is blocked, clean the nozzle using the supplied
wax removal loop.

Wax Removal Loop

Nozzle

When cleaning, do not force any object through the earphone nozzle! This will
damage the earphone sound lter.

If necessary, the supplied replacement nozzles may be used. See the back of
this guide for instructions on nozzle replacement.

Warning: The wax removal loop is only to be used to clean
earphones. Any other use, such as using the tool to clean ears,
could result in injury.

MAINTENANCE

Careful maintenance ensures a tight seal between the sleeve and nozzle,
improving sound quality and product safety.

Keep the earphones and sleeves as clean and dry as possible.

To clean sleeves, remove them from earphones, gently rinse in
warm water and air dry. Foam sleeves require a longer drying
time. Inspect for damage and replace if necessary.

Wipe the earphones and sleeves with mild antiseptic to avoid



infections. Do not use alcohol-based disinfectants.

Do not expose earphones to extreme temperatures.
