Connect to the amplifier: Align the red dot on the earphone cable connector with the red dot on the amplifier earphone output.
Disconnect from the amplifier: Pull the knurled connector collar up to safely release the lock on the earphone cable.
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. |
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.
The fit of the earphone can greatly affect sound quality.
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).
Grasp the body of earphone and gently twist to remove.
Note: Do not pull on cable to remove earphone.
Careful maintenance ensures a tight seal between the sleeve and nozzle, improving sound quality and product safety.
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.
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.
The cable connectors to the earphones may collect debris or other deposits that can affect audio quality. If this happens, disconnect the cables and clean them using a dry cotton swab.
