on a good eartip seal in the ear canal. See a video demonstration at

• Carefully insert the earphone
while pulling up and out on
the back of the ear.
• Twist the earphone up into the
ear canal while inserting, until
outside noise is blocked out.
• 3-flange eartips: Moistening
eases insertion.
• Foam eartips: Roll down or compress foam eartip before inserting.
Hold the eartip in place for about 5 seconds while the foam expands
to create a tight seal in the ear canal.
• Glider eartips: Simply push into ear canal.
Remove earphones slowly with a twisting motion to gradually break the seal.
Do not pull on the cable to remove the earphones.
