Using the earbuds
Selecting suitable ear adapters and ear
fins for optimum fit of the earbuds
The perceived sound quality including bass performance, the best
possible noise cancellation, the best speech quality in Communica-
tion mode and during phone calls as well as a secure hold of the ear-
buds in the ears depends to a large extent on the correct fit of the
earbuds. Therefore, you can choose between ear adapters and ear
fins in different sizes.
Silicone ear adapters
▷
Pull the ear adapter away from the in-ear sound tunnel.
▷
When mounting the new ear adapter, make sure that the raised
line in the silicone of the ear adapter is aligned with the white
marking on the support of the in-ear sound tunnel of the earbud.
The correct alignment of the ear adapters ensures proper func-
tion of the earbuds and the best sound quality.
▷
Mount the new ear adapter to the in-ear sound tunnel. Ensure that
it locks into place.
▷
Test which ear adapter size gives you the best sound quality and
the best wearing comfort.
You can choose between 3 different ear adapters in size S, M and
L. The ear adapters must fit snugly in the ear canal and com-
pletely seal your ears.
