Caution
Consult an audiologist or physician if you have excessive ear
wax,difficulty inserting the eartips,or discomfort after
prolonged use.The etyBLU dual-mode headset excludes most
external sounds.Always use extreme caution while using any
headset when operating a motorized vehicle.
Do not use the headset 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 time.

Earpiece Filter
The earpiece in the etyBLU headset has a special filter that
smoothes the frequency response and prevents earwax from
entering the earphone.The filter is located at the end of the
earphone and is visible when the eartip is removed.
Change the filter if loudness decreases or the sound quality
declines.
Note: Filters are not reusable.
