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.
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.
Noise-induced hearing loss is a function of exposure time, the average
sound level and the peak of very loud sounds. A sealed eartip and
lower listening levels allow for longer periods of safe
listening.
Care
• Do not expose the earphones to extreme temperatures.
• Avoid dropping and strong impact.
• Leave eartips on the earphones for shock protection.
• Do not pull on the cord to remove the earphone from the
audio device or the ear.
• Clean or replace eartips prior to use by others.
