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 o 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, diculty
inserting the eartips, or discomfort after prolonged use.
Do not listen at excessively loud levels. Research conrms 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.

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.
NOTE: Hold the earphone body–not the cable connector–when
removing the eartips to avoid accidentally detaching cable.
When changing eartips
make sure the eartip ts
securely on the stem of
the earphone.

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 t at 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-ange 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.
REMOVAL
Remove earphones slowly with a twisting motion to gradually break the seal.
Do not pull on the cable to remove the earphones.

CHANGING FILTERS
Etymotic earphones have special lters that smooth the frequency response
and prevent earwax from entering the earphones. A lter is located
at the end of the earphone and is visible when the eartip is removed.
If a lter becomes clogged, it should be replaced. A dirty lter will reduce
earphone output. The lter should be changed if loudness decreases or the
sound quality declines. Note: Filters are not reusable.
Filter Removal
Note: Use the tool to remove the lter.
1.
Remove eartip. 2. Insert tool into
the lter.
3. Remove lter.
2. Press gently
against a hard
surface to secure
it in place.
3. Re-attach eartip.1. Insert a new lter.
Filter Replacement
Note: Do not use the tool to replace the lter.
Note: Do not pull or twist
from the cable connector. It's
important to pull straight out.
