6i Isolator Earphones
Changing Filters

ETYMOTIC Isolator earphones have special filters that smooth the frequency response and prevent earwax from entering the earphones. These filters are located at the tip of the earphone and are visible when the eartip is removed. If the filters become clogged they should be replaced. A dirty filter will reduce earphone output. The frequency with which the filters need to be changed varies widely among users. The filters should be changed if the volume decreases or the sound quality declines.

To check: Remove the filter. If sound returns, insert a new filter.

Filter Removal Note: Once removed, the filters are not reusable.
