The first headphones utilizing full-range Air Motion Transformer technology, HEDDphone realizes the modern state-of-the-art potential of a groundbreaking 1960s invention to provide massive headroom and stunning resolution for effortlessly transparent, open, and natural 3-dimensional reproduction of any source material. HEDDphone is truly a major breakthrough in reproducing recorded music in greater detail.

Performance beyond the conventional

Three decades ago, HEDD founder and CTO Klaus Heinz designed the first commercial AMT tweeter based on physicist Oskar Heil’s original Air Motion Transformer. In recent years, Heinz has further improved its sonic performance over several major revisions for his loudspeaker tweeter designs at HEDD and ADAM Audio, the renowned manufacturer of high-end professional studio monitors. Now, HEDD has applied full-range AMT technology to audiophile-quality headphones.

Moves air faster for stunning transparency

To reproduce the entire audible frequency band (and beyond), HEDDphone incorporates VVT (Variable Velocity Transform) technology and utilizes a newly designed variable diaphragm geometry that expands the AMT principle to accommodate the requirements of a linear, full-range (10Hz–40kHz) headphone transducer. This electrodynamic transducer allows air to move significantly faster than conventional voice coil, electrostatic, or planar designs; the AMT uses a folded diaphragm that squeezes air out of multiple Kapton folds four times faster than a traditional driver’s piston-like movement would permit. Their amazing speed translates to stunning transparency and effortless resolution of quick transients.

Audiophile performance at home or in the studio

Given their exceptional audiophile performance, we recommend taking care in your choice of associate equipment, as HEDDphone will highlight any upstream signal chain inadequacies. HEDDphone is fully adjustable for a supremely comfortable fit, and its unerring accuracy and vanishingly low distortion make it perfect for long listening or monitoring sessions. At home or in the studio, once you’ve heard your music played back through HEDDphone, you’ll never go back to conventional headphones again!
