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.
