MAINTENANCE
Clean ear pads and headphones with soft, slightly damp cloth. Do not soak,
submerge or allow moisture to enter near the drivers or cable jacks. Ear pads
and cables can be purchased if they are worn out at: www.masterdynamic.com
Do not drop, sit on, or allow the headphones to be exposed to water, moisture,
or temperature extremes.
It is recommended that you return your headphones to their storage pouch
when not in use. To avoid damage, do not store other items in the canvas case
along with your headphones. CAUTION: Incorrectly rotating or over rotating the
earcups can damage the headphones.

longer to pair than anticipated. A factory reset can help speed up this process
by forgetting the list of previously connected devices.
