Etymotic mk5 Isolator Earphones - Manual (Page 2)

Caution
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.
Triple-flange eartips are reusable, but do not last indefinitely.
Frequent use, combined with the body chemistry of some users,
can degrade the eartips after 3-6 months, and on rare occasions
break off in someone’s ear. One of the first signs is discoloration.
Examine eartips before each use. If the eartips have lost their
original color and/or if the top one or two flanges appear worn
or too flexible, replace 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 use at excessively loud levels. Research confirms that
earphones that seal the ear canal allow listeners to listen at safer
levels. A sealed eartip and lower listening levels allow for longer
periods of safe listening.
