Using Earphones
Choosing a Sleeve
Select an earphone sleeve that provides the best fit and sound isolation. It should be easy to insert, fit comfortably, and easy to
remove.
Soft Flex Sleeves:
In small, medium, and large sizes. Made from pliable rubber.
Soft Foam Sleeves:
Compress the foam sleeve between your fingers and insert into the ear canal.
Hold in place for about ten seconds while the foam expands.
Triple-Flange Sleeves:
If desired, use scissors to trim the stem on the sleeve.
Wearing the Earphones
Carefully insert the earphone into the ear like an earplug, so that a tight seal is formed.
Important:
If there is a lack of low frequency response (bass), the earphone sleeve may not be forming a proper seal.
Gently push the earphone deeper into the ear canal or try using a a different sleeve.
Warning:
Do not push the earphone sleeve beyond the ear canal opening.
Wear earphone cables over the back of the ear to keep them in place during physical activity. Guide the cable down ei
ther the front or back of the body, and use the cable cinch to tighten up the remaining slack.
The fit of the earphone can greatly affect sound quality.
Changing Sleeves
Twist and pull to remove the sleeve from the nozzle.
Slide on a new sleeve so that it completely covers the barb and the nozzle.
