INTRODUCTION

ER•4 icroPro earphones, the first noise-isolating high-fidelity in-ear

earphones, used high performance, balanced armature drivers. These

high-definition transducers combine flat frequency response with passive

noise isolation. Noise reduction with ER•4 earphones occurs naturally

when the eartips are sealed in the ear canals.

Included with the earphones is a Channel- atching Compliance Graph

showing a frequency response curve for each custom-tuned, balanced

armature driver.

An assortment of ACCU•Fit™eartips is provided in this package. The triple-

flange eartips reduce sound an average of 35 dB, which is approximately

98% noise reduction. The foam eartips provide slightly more (42 dB) sound

reduction. Lowering outside sound allows you to hear the full dynamic range

of the recording without having to play it at unsafe levels.

The ER•4 icroPro series earphones produce the highest sound quality

of any high-definition earphones on the market today. We know you

will enjoy them.

ABOUT ETYMOTIC RESEARCHCAUTION

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.

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.

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.

ABOUT ETYMOTIC RESEARCHSELECTING 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.

English

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:

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.

CLEANING AND REPLACING EARTIPS

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 at

www.etymotic.com

• Carefully insert the earphone

while pulling up and out on

the back of the ear.

• Twist the earphone up into the

ear canal while inserting, until

outside noise is blocked out.

• 3-flange eartips: oistening

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.

• Glider eartips: Simply push into ear canal.

Remove earphones slowly with a twisting motion to gradually break the seal.

Do not pull on the cable to remove the earphones.

REMOVAL

ABOUT ETYMOTIC RESEARCH

CHANGING FILTERS

Etymotic earphones have special filters that smooth the frequency response

and prevent earwax from entering the earphones. An ACCU•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: ACCU•Filters are not reusable.

ACCU•Filter Removal Note: Use the tool to remove the filter.

ACCU•Filter Replacement Note: Do not use the tool to replace the filter.

1. Remove Eartip. 2. Insert tool into

the filter. 3. Remove filter.

1. Insert a new filter. 3. Re-attach eartip.

2. Press gently

against a hard

surface to secure

the filter in place.

ER-4PT TO ER-4S CONVERTER CABLE

Convert your ER•4PT earphones to ER•4S earphones with this inline

adapter cable. ER•4PT earphones have approximately 10 dB greater

output at high frequencies and 12 dB greater output at low frequencies

than ER•4S. ER•4S earphones were designed to compensate for the high

frequency emphasis in all CD recordings, in order to provide accurate sound

reproduction. ER•4S earphones can be used with a headphone amplifier

when using low-power portable devices.

TIP: Use the adapter cable with airplane sound systems when

the audio is too loud.
