Professional drivers - clear sound in the studio and beyond. AKG 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. A generous 40mm driver delivers 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. 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.
