  3. Clip the CONTROL BOX to a convenient place where the headphones will not shift when you move your head.
  4. Insert the 3.5mm plug directly into your audio source.
  5. Adjust the VOLUME DIAL on the CONTROL BOX to increase or decrease the volume to your preference.

Dual-Pin Adapter/T-Splitter Airplane Adapter

Insert the headphone's 3.5mm plug into either the DUAL-PIN or T-SPLITTER ADAPTER and then plug the adapter into your audio source.

Care and Maintenance

Before storing the headphones in the included carrying case, please fold the EARCUPS in one direction as illustrated below.

Important: The EARCUPS twist and fold in only one direction—forcing them to twist or fold in the wrong direction will damage the headphones.

To clean the earphones and case, wipe with a soft, dry cloth.
