2. 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 voice quality for phone calls and
a secure hold of the earbuds in the ear 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.
▷
Test which ear adapter size and which ear fins give you the best
sound quality and the best wearing comfort.
▷
You can choose between 4 different ear adapters in size XS, S, M
and L and 3 different ear fins in size S, M and L (> 24).
▷
Assign the right earbud to your right ear and the left earbud to
your left ear.
▷
Insert the earbuds at a slight angle into the ears and twist them
slightly into the ear canal so that they sit comfortably and snugly
in the ear canal and auricle (> 25).
