t without any discomfort. Rotate the

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 two dierent types of
acoustic lters: The gray lter is for enhanced perception of the
mid-frequencies and the black lter for enhanced perception of
bass and treble. 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 earwax (cerumen) 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 lters
are inserted in the sound tube.
Always use the same color of acoustic lters for both the left
and right earphone.
Replace the acoustic lters when they become dirty or clogged
and the sound of the earphones is aected.
