CHOOSING AN EARPHONE SLEEVE
Your earphones come with a selection of sleeves. Make sure the sleeve you
choose 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
If desired, the sleeve nozzle may be shortened. Use sharp
scissors to carefully trim the nozzle to the desired length.
Note: carefully slide the sleeve over the earphone nozzle barb for a secure grip.
