Filters

hf5 earphones have special filters that smooth the frequency
response and prevent earwax from entering the earphones.
A filter is located at the end of the earphone and is visible when
the eartip is removed. If a filter becomes clogged, it should be
replaced. A dirty filter will reduce earphone output. A filter
should be changed if the loudness decreases or the sound quality
declines.

Note:

Filters are not reusable.
