How to use
Connect the 3.5 mm plug to your audio source or use the included 6.3 mm adapter for professional equipment. Place the headphones over your ears so the padded earcups fully enclose the ear for optimal isolation. Adjust the headband for a secure but comfortable fit. For monitoring, set levels conservatively and increase volume gradually to avoid potential hearing damage. When not in use, fold the headphones and rotate the earcups to reduce storage volume.
Usage recommendations
For best monitoring accuracy, allow a short warm-up period at moderate listening levels before critical mixing. Keep the single-sided cable untwisted and store the headphones folded in a dry place to maintain the integrity of the earpads and hinges.
