 Sound Isolating Earphones 

  

These sound-isolating earphones 

with VoicePort inline microphone 

connect to your integrated media 

player cell phone. They feature 

WideBand MicroDrivers for an 

extended frequency soundstage 

that you can now enjoy at low 

listening levels, even in noisy 

environments. 

  INSERTING THE EARPHONES 

If the earphone seems to be lacking in low frequency response (bass), check 
the tightness of the seal between the earphone and your ear, or try one of the 
other sleeve options. 

  Warning: 

 Do not push the earphone sleeve beyond the ear canal opening. 

 

   WEARING THE EARPHONES 

  CHOOSING AN EARPHONE SLEEVE 

 Your earphones come with a selection of sleeves. Make sure the sleeve you 
use is easy to insert into your ear, fits comfortably, and is easy to remove from 
your ear. 

  

Make sure that the sleeve completely 
covers the earphone nozzle.

  If any part 

of the nozzle is exposed, the sleeve is 
not properly installed.  

 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. 

 Soft Flex Sleeves 

 In small, medium, and large sizes. Made from pliable rubber. 

 Triple-Flange Sleeves (Optional Accessory) 

 If desired, the sleeve nozzle may be shortened. Use sharp 
scissors to carefully trim the nozzle to the desired length.

 Wax Removal Loop 

  When cleaning, do not force any object through the earphone nozzle! 
 This will damage the earphone sound filter.
