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
1.
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 ca-
nal or try using a a different sleeve.
Warning: Do not push the earphone sleeve beyond the ear canal opening.
2.
Wear earphone cables over the back of the ear to keep them in place
during physical activity. Guide the cable down either 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.
Caution: If the barb or any of the nozzle is exposed, the sleeve is not
properly installed. Replace sleeves if they do not tightly grip the nozzle.
To ensure proper fit and performance, use only sleeves supplied by Shure
(unless using custom molded sleeves).

Removing the Earphones
Grasp the body of earphone and gently twist to remove.
Note: Do not pull on cable to remove earphone.
Maintenance and Cleaning
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. Ear sleeves must be completely
dry before reusing.
• Wipe the earphones and sleeves with mild antiseptic to avoid infections.
Do not use alcohol-based disinfectants.
• Do not expose earphones to extreme temperatures.
• Replace sleeves if they do not fit properly.
• Do not attempt to modify this product. Doing so will void the warranty
and could result in personal injury and/or product failure.
Cleaning the Earphone Nozzle
If you notice a change in sound quality, remove the sleeve and check the
nozzle of your earphone. If nozzle is blocked, clear obstruction by using
wire loop end of cleaning tool.
If no obstruction is found or if sound quality does not improve, replace the
sleeve with a new sleeve.
Cleaning Tool
Caution: When cleaning, do not force any object through the earphone
nozzle! This will damage the earphone sound filter.
Warning: The cleaning tool is only to be used to clean the earphones.
Any other use, such as using the tool to clean ears or foam sleeve, could
result in injury.
