Style, comfort, quality Your music rocks - make sure you hear every detail with the AKG K52 over-ear, closed back headphones. Professional-grade 40mm drivers reveal even the subtlest nuances, so you can be confident your mix will translate accurately on any system. Whether you're monitoring vocals or tracking a bass line, the self-adjusting headband and lightweight design will provide hours of comfort. Designed by the company whose mics and headphones have helped create some of the world's most iconic recordings, the durable K52 headphones deliver great sound wherever your music takes you. Professional drivers - clear sound in the studio and beyond These K52 headphones deliver authoritative, extended low-frequency response that gives definition to kick drums and bass guitars. At the same time, the detail yet precisely balanced high-frequency response reveals the nuance in vocals, guitars and acoustic instruments. The generous 40mm drivers deliver high sensitivity for powerful output, plus an extended frequency response that reveals every detail. The K52s also feature a low-impedance design for compatibility with a broad range of playback devices, from professional studio gear to portable music players. Closed-back design - get lost in your sound The K52 headphones' closed-back design eliminates audio leakage and delivers sound to your ears only. You won't hear the drummer drop his sticks in the middle of tracking - and the mic won't pick up the sound of the click track in your headphones. 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. Our innovative design gives you the freedom to move your head in any direction, without letting sound in or out. With the K52, you'll enjoy a private workspace, no matter where you choose to create. The style that fits all - comfortable listening Nailing the perfect take sometimes means tracking the same part for hours - and that's where comfort really counts. We designed our 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 K52 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. To sum it up, these high-performance headphones sound, feel and look great.
