t without any discomfort. Rotate the
earphones as shown, pointing diagonally
towards the top of the ear. Gently pull the

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 lters
The acoustic lters have an essential acoustic impact on the
sound of the earphones. The purpose of this lter is to deliver
sound that matches what one perceives when listening with
non-occluded ears. The product comes with three dierent types
of acoustic lters: The gray lter is for enhanced perception of
the mid-frequencies, the black lter for enhanced perception of
bass and treble and the green lter for extra bass. Because each
individual‘s perception of sound is unique, Audéo PFE allow you
to choose the lter that suits your personal preferences. Another
function of the acoustic lter is to prevent dirt from entering the
sound tube.
Make sure that the acoustic lters are in place before using
the earphones. The earphones only function correctly if the
acoustic lters are inserted in the sound tube.
Always use the same color of acoustic lters for both the left
and right earphone.
Replace the lters when they become dirty or clogged and the
sound of the earphones is aected.
