Setup

Unfold the Headphones: Gently unfold the earcups from their collapsed position until they are fully extended and ready for use.
Connect to Audio Source:

- For devices with a 6.35mm (1/4-inch) audio jack (e.g., professional audio mixers, amplifiers, studio equipment), screw the included 1/4-inch adapter onto the 3.5mm plug. Ensure it is securely fastened.
Adjust Headband: Place the headphones on your head and adjust the headband sliders on both sides to ensure a comfortable and secure fit. The earcups should fully enclose your ears.
