Folding the Headphones
These headphones can be collapsed two different ways for space-saving 
storage and transportation: 
1.  Adjust the headband to its largest size, and fold in the earcups, 
bringing together the earpads.
2. Fold one earcup in, and collapse the other earcup in on top of it.
Cleaning the Headphones
To clean the headphones, use a soft, damp cloth. If necessary, the 
headphones can be cleaned with soapy water making sure to keep all 
moisture away from the speakers themselves. 
Listen Responsibly
Hearing health is critical to your enjoyment of music and to your quality of 
life. Listen to your music in a responsible manner that protects your  
long-term hearing.
4  Always turn the volume down on your listening device before putting 
on your new headphones. Once your Studiophile headphones are 
on, gradually increase the volume to a moderate listening level.
4  Using headphones at high volumes for extended periods of time can 
permanently damage your hearing. 
4  Hearing damage can be gradual and cumulative. In many cases 
there are no obvious warning signs. A hearing test and medical 
examination are the only way to accurately diagnose hearing 
damage. We strongly recommend you make an appointment with 
your ear doctor if you notice any of the following symptoms:
   i) Ringing or buzzing in the ears 
   ii) Difficulty in understanding speech 
   iii) Muffling of sounds
4  Do not use these headphones in any environment where a failure 
to hear surrounding sounds could be dangerous. In no way should 
these headphones be used while driving a car, biking, or operating 
machinery.

4  When using your headphones with an unfamiliar or unstable sound 
system (airplane, public access ports, etc.), make sure the volume is 
low to prevent “break-in” bursts of loud sounds.
4  Keep your M-Audio headphones away from young children. This 
product includes small parts that may create a choking hazard.
4  M-Audio recommends limiting the use of headphones. Different 
individuals may be impacted to a different degree by high noise 
levels (volumes exceeding 85 dB(A)). Regular exposure to loud 
headphones may be dangerous to your hearing and can cause 
permanent hearing loss.
Please review and consider the following Occupational Safety Health 
Administration (“OSHA”) guidelines regarding the maximum time 
exposure to sound pressure levels before hearing damage may occur.
OSHA has established the following noise exposure 
limits:
Sound Pressure  
Level dB(A)
90 8 hours
95 4 hours
100 2 hours
105 1 hour
110 30 minutes
Warning: Exposure to sound pressure levels above 115 dB(A) for even 
short periods of time can cause permanent hearing damage.
The preceding OSHA exposure levels should be considered maximum 
limits. Compliance with the OSHA limits will not necessarily provide 
you with protection from potential hearing loss. 
For more information visit the OSHA website at www.osha.gov.
