  E3c 

 Sound Isolating Earphones 

 With a sleek, low profile design, 

the E3c combines WideBand 

MicroDriver technology and 

incredible sound isolation for 

detailed highs 

and enhanced 

bass across an 

extended frequency 

soundstage. 

Originally designed 

for the demanding 

audio specifications 

of professional 

musicians, the E3c 

is an ideal choice for any 

home or portable audio 

device. 

  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 

 Three popular methods for wearing the earphones are illustrated below. 

  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. 

  CLEANING THE EARPHONE NOZZLE 

 If the nozzle of your earphone is blocked, clean the nozzle using the supplied 
wax removal loop.

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.  

 Nozzle 

 Wax Removal Loop 

Tighten the cable and take up slack by raising the cable sleeve  

 .  

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