Ety8 Earphones have special filters to smooth the frequency response and to prevent earwax from entering the earphones. Change filters if volume decreases or the sound quality declines.

Removal 1. Remove eartip. 2. Insert tool into     the filter. 3. Remove filter.     Discard old filter     (filters are not     reusable).

Replacement 4. Insert a new filter     and press gently     against a hard     surface to secure     it in place. 5. Attach eartip.
