Using the AKG K812 headphones is easy. Just plug the cable into your device using the 3.5 mm connector. If your device has a 6.3 mm port, use the included adapter. Put the headphones on your head, adjust the headband for a comfortable fit, and enjoy your music or audio. When you're done, store them on the premium wooden stand to keep them in good shape. Remember to keep the headphones away from moisture and extreme temperatures. Don't pull the cable too hard to avoid damage. Clean the earpads gently with a soft, dry cloth every once in a while to keep them looking and smelling fresh.
