Our 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. Our 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.
