Changing Filters - Etymotic Research Isolator ER-6 User Manual

CHANGING FILTERS

ER-4 MicroPro Earphones have special filters that shape the frequency
response and prevent earwax from entering the earphones. These filters,
identified by a green acoustic mesh in a small metal barrel, are located at the
end of the earphone and are visible when the eartip is removed. When the
filters become clogged they should be replaced. A dirty filter will reduce or
block the earphone output. The frequency with which the filters need to be
changed will vary widely among users. The filters should be changed if the
volume decreases or the sound quality declines.
