TRY ANOTHER SIZE

Wear the earbuds for an extended period of time. If the earbuds don’t feel comfortable or secure, or noise cancellation or sound quality isn’t as expected, try another size eartip or stability band.
You may need to try all three eartips or band sizes,, or use a different size eartip or band for each ear.

Eartips
The eartips come in small, medium, and large.

Medium eartips come attached to the earbuds. If they feel too small, try large eartips. If they feel too big, try small eartips.

Stability bands 
The stability bands are marked with size 1 (small), 2 (medium), or 3 (large) and an R (right) or L (left).

Size 1 bands come attached to the earbuds. If they feel too small, try size 2 bands.

CHANGE THE EARTIPS

1. Holding the earbud, gently squeeze the eartip and peel it away from the earbud.

   

   CAUTION: To prevent tearing, do NOT pull on the edge of the eartip.

2. Choose a new eartip size (see page 19).
3. Align the eartip with the earbud nozzle and press the eartip onto the nozzle until you feel it snap securely into place and hear it click.

   NOTE: You may need to use a different size eartip for each ear.
5. Insert the earbuds (see page 16).
