inline control switch allows you to

easily transition from listening to
music to answering phone calls.

WideBand MicroDrivers deliver an

extended frequency soundstage

that you can now enjoy at low

listening levels, even in noisy

environments.

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.
Make sure that the sleeve completely covers
the earphone nozzle. If any part of the
nozzle is exposed, the sleeve is not properly
installed.

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.

Flex Sleeves

In small, medium, and large sizes. Made from translucent
PVC.

Soft Flex Sleeves

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

Foam Sleeves

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)

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

CLEANING THE EARPHONE NOZZLE

wax removal loop.

Use a slow twisting motion to remove the earphones.
Never pull on the earphone cord.

Warning: If a sleeve becomes lodged in your ear,
seek skilled medical assistance to remove the sleeve.
Damage to the ear may be caused by non-professionals
attempting to remove the sleeve.

Prior to inserting the earphone, always recheck the
sleeve to make sure it is firmly attached to the nozzle.

Turn up the volume control only far enough to hear
properly.

Ringing in the ears may indicate that the volume level is
too high. Try lowering the volume.

If you connect these earphones to an airplane’s sound
system, listen at low levels so that loud messages from
the pilot do not cause discomfort.

Have your ears checked by an audiologist on a regular
basis. If you experience wax buildup, discontinue use
until an audiologist has examined your ears.

Stop using the earphones if they are causing great
discomfort or infection.
