Inserting the Earphones
Important: If there seems to
be a lack of low frequency
response (bass), this means
that the earphone sleeve
is not forming a tight seal.
Gently push the earphone
deeper into the ear canal or
try a different sleeve.
Warning: Do not push the earphone sleeve beyond the ear canal opening.

Insert the earphones so they form
a tight seal. 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 perfor-
mance, use only sleeves supplied by Shure (unless using custom molded sleeves).
