MEElectronics NoiseSHIELD NS63 - Manual (Page 5)

Warning
Noise canceling headphones attenuate external low-pitched sounds.
Be aware that when the active noise canceling feature is on auditory
queues will sound different.
Do not use headphones at high volumes for extended periods of time
as doing so will result in permanent hearing damage. It is advised you
keep volume levels moderate to low at all times for your safety. Do
not use while driving a car, cycling, operating machinery, or
performing other activities that require hearing surrounding sounds.
Please visit www.osha.gov for more info.
It is advised to turn the volume on your music player all the way
down before connecting your headphones. After the headphones are
connected, gradually increase the volume until a comfortable listening
level is achieved.
Do not store the headphones in direct sunlight,
near heating devices or in hot, humid or dusty places.
Do not subject the headphones to strong impact.
Do not allow the headphones to become wet.
