Hearing safety
/LVWHQDWDPRGHUDWHYROXPH
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.

Set your volume control at a low setting.
Slowly increase the sound until you can hear it comfortably and clearly, without distortion.
