sleeve up and onto the stem until it
fits securely in place.

to make sure it covers the stem

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.

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
