Instructions For Use - Etymotic ER4

Proper Insertion

Important: Sound quality, full bass response and noise isolation all depend on a good eartip seal in the ear canal. See a video demonstration of how to get a proper fit in the Earphone Insertion Video

  • While pulling up and out on the back of the ear carefully insert the earphone.
  • Twist the earphone into the ear canal while inserting, until outside noise is blocked out.
     
  • 3-flange eartips: Moistening eases insertion.
  • Foam eartips: Roll down or compress foam eartip before inserting. Hold the eartip in place for about 5 seconds while the foam expands to create a tight seal in the ear canal.

Changing Filters

Etymotic 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. The filter should be changed if loudness decreases or the sound quality declines.

Note:Filters are not reusable.

To clean 3-flange eartips:

  1. Remove the eartip from the earphone.
  2. Clean with water and mild soap.
  3. Dry the eartip before placing it back on the earphone.

  • Leave eartips on the earphones for shock protection.
  • Do not pull on the cord to remove the earphone from the audio device or the ear.
