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 ear tips,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,bicyclingor 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.
