Situating the cables around your ears
●
E1c, E2c, E3c, E4c, i2c, i3c, and i4c: wrap the earphone cord over the top and down the back of the ear.
●
E5c: wrap the form-fitted wire over the top and down the back of the ear.
●
Use the adjustment tube to secure the cables comfortably behind your head.
Inserting the earphones
To insert the earphone, pull the ear upward and outward to straighten out the ear canal. With the cable coming
over your ear, compress the sleeve with your fingers and insert the earphone into your ear.
Creating your personal fit
The quality of the frequency response and sound isolation depends on how well the sleeves seal. 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.
●
Flex and soft flex sleeves:
Try the different sizes to determine 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 before inserting it. Hold the earphone in place for about 10 seconds while the foam expands and
creates a tight seal.
How to Use Earphones
Shure Sound Isolating Earphones are ideally suited for use with portable MP3, DVD, and CD players as
well as any listening device with a 3.5 mm (1/8-inch) stereo jack. The 1/4" to 1/8" adapter included
with the E4c and E5c also enables you to connect to sources with 1/4" jacks, such as home audio
receivers. Plug them into your favorite listening device, or bring them with you when you fly. The result
will be the same - an outstanding audio experience, wherever your music takes you.
To enjoy the superior sound isolation and the rich, studio-quality sound of the E Series and I Series, it
is important to fit your earphones properly into your ears. We recommend taking some time to experiment
with your Personal Fit Kit to find out what works best for you.

●
E2c and i2c: clear earphone = left ear; clear-and-black earphone = right ear
●
E3c, E4c, i3c and i4c: earphone with L = left ear; earphone with R = right ear
