ENGLISH

It is difficult to measure the exact Sound Pressure Levels (SPL) present at the eardrum, since

the SPL in the ear is affected by ambient sound from floor wedges or other devices in addition

to the volume setting on the PSM. The isolation provided by the fit of quality earphones is

also an important factor in determining the SPL in the ear.

Here are some general tips to follow for safe use of this product:

1. Turn up the volume control only far enough to hear properly.

2. Ringing in the ears may indicate that the gain levels are too high. Try lowering

the gain levels.

3. Shure recommends that you have your ears checked by an audiologist on a regular

basis. If you experience wax buildup in your ears, stop using the earphones until an

audiologist has examined your ears.

4. Wipe the earphones with an antiseptic before and after use to avoid infections.

Stop using the earphones if they are causing great discomfort or infection.

WARNING!

USING THIS SYSTEM AT EXCESSIVE VOLUMES

CAN CAUSE PERMANENT HEARING DAMAGE.

USE THE LOWEST VOLUME LEVEL POSSIBLE.

To use this system safely, avoid prolonged listening at excessive sound pressure levels.

Please use the following guidelines established by the U.S. Occupational Safety Health

Administration (OSHA) on maximum time exposure to sound pressure levels before hear-

ing damage occurs.

90 dB SPL at 8 hours

95 dB SPL at 4 hours

100 dB SPL at 2 hours

105 dB SPL at 1 hour

110 dB SPL at 1/2hour

115 dB SPL at 15 minutes

120 dB SPL - avoid or hearing damage may occur

EARPHONE COMPONENTS

The earphone components are illustrated below, using the E2 model as an example. Ear-

phone shapes vary, depending on the model.

Earphones: When properly inserted in the ear, the Shure logo will appear right-side up

on the outside of the earphone with the cable exit pointing upwards. For complete in-

structions on inserting earphones, see page 4.

Sleeves: All earphone models come with a pair of sleeves installed and an additional

assortment of flex and foam sleeves. See Sleeve Varieties on page 5.

Adjustment Tube: For a secure fit, slide the adjustment tube up and down to adjust the

slack of the cables leading to the earphones.

Input Connector: 3.5 mm (1/8-inch) plug connects to the 3.5 mm stereo earphone out-

put of a listening device.

Nozzle: This part of the earphone, which is covered by the sleeve, delivers the sound

into the ear canal. It’s important to keep this component clean (see Care and Cleaning

on page 7).

Wax Guard: (model E2 only) The earphones include special wax guards (not installed)

for preventing earwax from entering the nozzle. For instructions on installing the wax

guards, see page 9.

ENGLISH

INSERTING THE EARPHONES

The quality of both the frequency response and the sound isolation depend on how well the

earphone sleeve seals the ear canal. If the earphone seems to be lacking in low frequency

response, try one of the other sleeve options to obtain a better seal.

2. E2 and E3: wrap the earphone cord over the top and down the back of the ear.

E5: wrap the formfitting wire over the top and down the back of the ear.

3. Use the adjustment tube to secure the cables comfortably.

1. Insert the earphones using the following guidelines:

•Note the difference between the right and left earphones:

E2: earphone all one color = left ear

bicolored earphone = right ear

E3: earphone with blue dot and “L” = left ear

earphone with red dot and “R” = right ear

E5: earphone with blue dot = left ear

earphone with red dot = right ear

When inserting the earphones, pull the ear up-

ward and outward to straighten out the ear ca-

nal, as illustrated.

•Flex sleeves - Try the different sizes to deter-

mine the best fit for comfort and isolation.

•Foam sleeves - Compress the foam sleeve at

the end of the earphone by rolling it between

your thumb and forefinger. Insert the ear-

phone into your ear and hold it in place for

about 10 seconds while the foam expands and

creates a tight seal. The E2 comes with three

sizes of foam sleeves: try the different sizes to

determine the most comfortable fit.

ENGLISH

CONNECTING TO A BODY PACK

1. Turn down the volume of your listening device.

2. Connect the 3.5 mm (1/8-inch) plug into the earphone output jack.

3. Insert earphones into your ears (see previous page).

4. Slowly raise the volume to a comfortable listening level.

SLEEVE VARIETIES

Your earphones include a fit kit with a variety of sleeve options so you can find the best sleeve

fit for any application. The E3 and E5 also come with a cleaning tool (see Figure 1 on page 7)

and the E2 comes with wax guards (see the Wax Guard section on page 9) to prevent wax

buildup in the earphone nozzle.

ENGLISH

CHANGING SLEEVES

The sleeves at the end of the earphones can be replaced by sliding them off and on. A com-

bination of twisting and pulling is recommended for sleeve removal.

NOTE: On each foam sleeve there is a rough side and a smooth side. For greater com-

fort, Shure recommends that you place the smooth side facing out, away from the ear-

phone. On the E2 model earphones, the sleeve will only fit the earphone properly with

the smooth side facing out.

Foam Sleeves. These disposable foam sleeves compress to fit in the ear

canal. Once in the ear, the foam expands to form a tight seal. Once tightly

sealed, the sleeves hold the earphones firmly in place. The E3 and E5 come

with yellow foam sleeves. The E2 earphones come with three sizes of orange foam

sleeves to choose from—small, medium or large—for the best fit.

Flex Sleeves. These reusable sleeves, made of a clear pliable plastic

(PA756) or a soft, gray silicone rubber (PA758), fit comfortably in the ear and

allow for ease of insertion. Choose from 3 sizes—small, medium or large—

for the best fit. These should be cleaned regularly, using alcohol wipes or

an antiseptic.

Triple-Flange Sleeves (optional accessory for E3 and E5 only). These

reusable sleeves form a tighter seal than flex sleeves while holding the

earphones firmly in place. These should be cleaned regularly, using

alcohol wipes or an antiseptic.

ROUGH SIDE SMOOTH SIDE

IMPORTANT: Make sure that the sleeve complete-

ly covers the nozzle. If the nozzle is exposed, the

sleeve is not properly installed.

ENGLISH

CARE AND CLEANING

Follow these tips to prevent service costs and ear infections:

•Avoid getting moisture in the nozzle, as this can adversely affect sound quality.

Sweat entering the nozzle may cause the earphone to temporarily stop working.

However, normal operation often returns after the earphone dries out.

•Avoid striking or dropping the earphones. Extreme shock can damage them.

•Return earphones to carrying pouch when not in use.

•E3/E5: clean the nozzles after each use using the supplied wax removal tool.

FIGURE 1: E3/E5 Wax Removal

•E2: Routinely check the wax guard on the tips of the nozzles (see figure 2 on

page 9). If the wax guards appear to be clogged, replace them.

•Foam sleeves should be disposed of and replaced when they get dirty.

•Flex and triple-flange sleeves should be cleaned with an antiseptic or soapy

water after each use and when sharing.

•Always remove the sleeve from the earphone nozzle before cleaning.

WAX REMOVAL LOOP

ENGLISH

•Wipe down the case and cable with an antiseptic after each use. Stop using the

earphones if they are causing great discomfort or infection.

the sound quality. If you experience sound loss, check the nozzles for clogging before

sending the product in for service. There is a service charge for removing wax.

If you believe this product is defective within the warranty period, carefully repack the unit,

insure it and return it postage prepaid to:

ENGLISH

WAX GUARD

You should place wax guards on the nozzle of your E2 earphones before using them. These

protective rings are found on an adhesive strip in the fit kit that comes with your earphones.

To place a wax guard on one of your E2 earphones:

1. Remove the sleeve from the earphone nozzle.

2. If there is a dirty wax guard on the earphone, peel it off.

3. Clean the tip of the E2 nozzle with an antiseptic or alcohol wipe.

4. Make sure that the tip of the nozzle is dry, then remove a wax guard from the supplied

strip and place it on the tip of the nozzle, adhesive side down.

5. Replace the sleeve on the earphone.
