opening of the ear canal.
2. Adjust the position of the earbud until it is secure.
Choosing the correct ear tips
Select the size that gives you the best comfort and fit in
each ear. To determine the best fit, you may need to try all
sizes. You may need a different size for each ear.
Fitting the earbuds to your ear
The ear tip allows the earbud to rest comfortably and
securely in your ear.
Changing the ear tips
1. Holding the earbud by the stem, gently grasp the attached
ear tip and peel it away from the earbud.
2. Align the opening of the new ear tip with the earbud
