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.
