The Harman Kardon engineering team, which developed the world’s first stereo receiver, now introduces the first line of Harman Kardon headphones. The in-ear, on-ear and over-ear headphones achieve a harmonic blend of sophistication and simplicity. From high-quality materials to exceptional acoustic performance, the new headphones reflect the Harman Kardon commitment to innovative industrial design and uncompromising sound quality. A triumph of craftsmanship and audio engineering, Harman Kardon headphones are designed for those with an eye for style and an ear for sound. Drawing from a rich heritage of acoustic innovation, the lightweight, comfortable Harman Kardon AE headphones feature an aluminum-alloy housing for extended bass and true low-frequency reproduction. Optimized 3/8-inch (9-millimeter) drivers deliver extended bass response, wide dynamic levels, high sound-pressure levels and sonic clarity at all volume levels. The in-ear headphones include silicone sleeves in three sizes for optimum comfort and an Apple three-button remote with built-in microphone for phone calls.
