f. The ear tips should seal the ear canal and
fit without any discomfort. Rotate the
earphones as shown, pointing diagonally
towards the top of the ear. Gently pull the
cable downwards to ensure a perfect fit.
If you feel that the ear tips are too loose (insufficient seal) or too
tight (discomfort), try another size. To remove the earphones pull
them out gently with a small rotation in order to break the seal.
Do not pull the cable to remove the earphones from your
ear.
4.3. Acoustic filters
The acoustic filters have an essential acoustic impact on the
sound of the earphones. The purpose of this filter is to deliver
sound that matches what one perceives when listening with
non-occluded ears. The product comes with three different types
of acoustic filters: The gray filter is for enhanced perception of
the mid-frequencies, the black filter for enhanced perception of
bass and treble and the green filter for extra bass. Because each
individual‘s perception of sound is unique, Audéo PFE allow you
to choose the filter that suits your personal preferences. Another
function of the acoustic filter is to prevent dirt from entering the
sound tube.
Make sure that the acoustic filters are in place before using
the earphones. The earphones only function correctly if the
acoustic filters are inserted in the sound tube.
Always use the same color of acoustic filters for both the left
and right earphone.
Replace the filters when they become dirty or clogged and the
sound of the earphones is affected.
