IDENTIFICATION

SELECTING AN EARTIP

The eartips that are most comfortable are the best choice, but they should seal well in the ears for best noise isolation and sound quality. When changing eartips make sure the eartip fits securely on the stem of the earphone.
NOTE: Hold the earphone body–not the cable connector–when removing the eartips to avoid accidentally detaching the cable.

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 at http://www.etymotic.com

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.

Note: Do not pull or twist from the cable connector. It's important to pull straight out.

Attaching Cables

Press together until you feel it snap in.

Note: If the key tab is not aligned with the notch, the snap will not engage.

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.

Remove eartip.
Insert tool into the filter.
Remove filter.

Filter Replacement

Note: Do not use the tool to replace the filter.

Setup Guide

To utilize the Etymotic ER4SR earbuds, adhere to the subsequent instructions:

Place the ear tips into your ear canals, making sure they fit tightly and are seure.
Attach the earbuds to your audio device by utilizing the removable wire and a 35mm stereo mini-plug.
Begin playing your audio source and modify the volume to your preferred level.
To detach the earbuds, delicately rotate and extract them from your ear canals.

CLEANING AND REPLACING EARTIPS

Over time eartips may lose their elasticity. For best performance and retention, replace 3-flange eartips every 60-90 days. Replace foam and glider eartips frequently.

To clean 3-flange eartips:

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

IMPORTANT

Do not expose the earphones to extreme temperatures.
Avoid dropping and strong impact.
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.
Clean or replace eartips prior to use by others.
For best performance and retention in the ear, replace 3-flange eartips every 60-90 days.
Replace foam eartips frequently.

CAUTION

Etymotic earphones exclude most external sounds. It is unsafe to use in-ear earphones while operating a motorized vehicle, operating machinery, bicycling or jogging, because you may not be alerted to potential danger.
In rare instances, an eartip may come off in the ear canal when removing the earphone. If this should occur and the eartip cannot be easily removed, it is recommended that you promptly contact an audiologist or other medical professional. A professional can use blunt tweezers to remove the eartip.
Consult an audiologist or physician if you have excessive ear wax, difficulty inserting the eartips, or discomfort after prolonged use.
Do not listen at excessively loud levels. Research confirms that earphones that seal the ear canal allow listeners to listen at safer levels. Noise-induced hearing loss is a function of exposure time, the average sound level, and the peak output of very loud sounds. A sealed eartip and lower listening levels allow for longer periods of safe listening.

Troubleshooting

Here are common issues and solutions for the Etymotic Earphones ER4SR:

Problem: Lack of audio output from the earphones.
Resolution: Verify that the earbuds are securely attached to your audio device and that the volume is set to a high level. Inspect the earphones and cord for any signs of debris or damage.
Problem: Inadequate noise isolation.
Resolution: Verify that the ear tips are correctly put into your ear canals, forming a tight and secure fit. Experiment with several ear tips to discover the optimal fit for your ears.
Problem: Sound that is distorted or uneven.
Resolution: Examine the earbuds and cord for any signs of damage. Attempt to modify the volume settings or transition to an alternative audio input.
