PROTECTING YOUR INVESTMENT….

For long lasting enjoyment of your headphones, you should respect their limits and avoid excessive volume levels for music 
or movie playback. Excessive volume levels can damage all headphones.

If your headphones are pushed to excessive volume levels, they could be driven into “clipping”. This could result in severe 
or permanent injury. When using your headphones at loud levels, listen carefully for any sign of harsh, garbled midrange 
and diminishing intelligibility. If detected, turn the volume down immediately.

NEVER TEST PEAK LISTENING LEVELS OF THE HEADPHONES BY TURNING THE VOLUME UP ALL THE WAY!
