Hearing Safety

Listen at a moderate volume.
Using headphones at a high volume can impair
your hearing. This product can produce sounds
in decibel ranges that may cause hearing loss for
a normal person, even for exposure less than a
minute. The higher decibel ranges are offered
for those that may have already experienced
some hearing loss.
Sound can be deceiving. Over time your hearing
"comfort level" adapts to higher volumes of
sound. So after prolonged listening, what sounds
"normal" can actually be loud and harmful to
your hearing. To guard against this, set your
volume to a safe level before your hearing
adapts and leave it there.
To establish a safe volume level:
Set your volume control at a low setting.
Slowly increase the sound until you can hear it
comfortably and clearly, without distortion.
