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.
