1.   To remove the sleeve on the 
earphone, pull gently on one sides 
of the sleeve at the base of the stem 
until the sleeve comes off.
2.   Position the replacement sleeve at 
a slight downward angle over the 
earphone stem. Gently push the 
sleeve up and onto the stem until it 
fits securely in place.
3.   Push the end of the sleeve gently 
to make sure it covers the stem 
completely.
Connecting to your audio device
1.   Turn the volume of your audio device all the way down.
2.   Plug the earphone mini-plug into the headphone jack on your audio device.
3.   Put on your earphones.
4.   Turn up the audio device volume slowly.
Make sure you find the left (L) or right (R) marking on the 
inside of each earphone so you know which side is which.
Make sure the sleeves cover the end of the earphone stems.
Finally, gently insert your earphones in each ear, just far enough that they fit 
securely—do not push beyond the ear canal opening!
Note: Once you’ve put on your earphones, use the cord adjuster to increase or 
decrease the amount of slack in the cord.
These earphones come with the small sleeves installed. If these don’t fit the way you 
want them to, try a different size—the next section tells you how to change sleeves.
