SAFE USE
Here are some general tips to follow for safe use of this product:
•Turn up the volume control only far enough to hear properly.
•Ringing in the ears may indicate that the volume level is too high. Try lowering
the volume.
•If you are connecting these earphones to an airplane's sound system, listen at
low levels so when loud messages from the pilot break into the program you do not
experience discomfort.
•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.
•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 THESE EARPHONES AT EXCESSIVE VOLUMES
CAN CAUSE PERMANENT HEARING DAMAGE.
USE THE LOWEST VOLUME LEVEL POSSIBLE.
WARNING!
DUE TO THE ISOLATING CHARACTERISTICS OF THESE EARPHONES, DO NOT USE
THEM WHILE DRIVING OR WHILE BIKING, WALKING OR JOGGING WHERE VEHICULAR
TRAFFIC IS PRESENT, OR IN ANY OTHER ACTIVITY WHERE A FAILURE TO HEAR
SURROUNDING SOUNDS COULD BE DANGEROUS.

EARPHONE COMPONENTS
The earphone components are illustrated below, using the E2c 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.
3.5 mm (1/8-inch) Input Connector: connects to the stereo earphone output of a lis-
tening 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 E2c only) The earphones include special wax guards (not installed)
for preventing earwax from entering the nozzles. For installation instructions, 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, insert the earphone deeper into the ear canal to obtain a better seal, or try one of
the other sleeve options.
2. E2c and E3c: wrap the earphone cord over the top and down the back of the ear.
E5c: wrap the formfitting wire over the top and down the back of the ear.
3. Use the adjustment tube to secure the cables comfortably.

•Note the difference between the right and left earphones:
E2c: earphone all one color = left ear
bicolored earphone = right ear
E3c: earphone with “L” = left ear
earphone with “R” = right ear
E5c: earphone with blue dot = left ear
earphone with red dot = right ear
When inserting the earphones, pull the ear
upward and outward to straighten out the ear
canal, 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 E2c comes with
three sizes of foam sleeves: try the different
sizes to determine the most comfortable fit.

CONNECTING TO A LISTENING DEVICE
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 E3c and E5c also come with a cleaning tool (see Figure 1 on
page 7) and the E2c comes with wax guards (see the Wax Guard section on page 9) to pre-
vent wax buildup in the earphone nozzle.
WARNING: Always turn the volume down before plugging the earphones into a
sound source.
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 E3c and E5c
come with yellow foam sleeves. The E2c 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.

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. With the E2c model earphones, the sleeve will only fit the earphone properly with
the smooth side facing out.
Triple-Flange Sleeves (optional accessory for E3c and E5c 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.

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.
•E3c/E5c: clean the nozzles after each use using the supplied wax removal tool.
FIGURE 1: E3c/E5c Wax Removal
•E2c: 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 or when sharing.
•Always remove the sleeve from the earphone nozzle before cleaning.

WAX GUARD
You should place wax guards on the nozzle of your E2c 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 E2c 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 E2c 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.
