Sound Isolating Earphones

These sound-isolating earphones with

VoicePort inline microphone connect

to both your cell phone and portable

media player. The inline control switch

allows you to easily transition from

listening to music to answering

phone calls. Tuned Port-enhanced

High Definition Drivers deliver a

superior frequency soundstage with

extended bass 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.

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.

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

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.

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

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

Wax Removal Loop
