At the same time, the detailed yet precisely balanced high-frequency response reveals the nuance in vocals, guitars and acoustic instruments. Generous 40mm drivers deliver high sensitivity for powerful output, plus an extended frequency response that reveals every detail. The K72s also feature a low-impedance design for compatibility with a broad range of playback devices, from professional studio gear to portable music playersClosed-back design - get lost in your soundThe K72 headphones' closed-back design eliminates audio leakage and delivers sound to your ears only. The mic won't pick up the sound of the click track in your headphones - and you'll always be able to mix peacefully without being distracted by outside noise. This exceptional level of audio isolation is due to a new acoustic chamber, which sits between the ear cup and the hinge that connects to the headband. Innovative design gives you the freedom to move your head in any direction, without letting sound in or out. With the K72, you'll enjoy a private workspace, no matter where you choose to create.The style that fits all - comfortable listeningGetting the perfect mix sometimes means monitoring track levels for hours - and that's when comfort really counts. AKG designed unique self-adjusting headband to automatically create the perfect fit for every band member. No need to mess with delicate sizing mechanisms, which have the potential to break over time. The exposed headband design keeps the K72 headphones comfortably light, without compromising driver size. Breathable, lightweight ear pads encircle your ears, rather than putting pressure on them. And a single-sided cable gives you freedom to move.
