HEDD HEDDphone Studio Monitoring Headphones

HEDD is proud to introduce the first full range Air Motion Transformer headphones to audiophiles and recording artists worldwide. The Air Motion Transformer (AMT) is an electrodynamic transducer that allows to move air significantly faster than common voice coil, planar, or electrostatic systems. Their traditional piston-like movement is overcome by a folded diaphragm that squeezes out air four times faster: A breakthrough for capturing more details in a musical recording.

30 years ago HEDD founder and CTO Klaus Heinz designed the first compact and marketable AMT tweeter based on American-German Physicist Oskar Heil’s original Air Motion Transformer invention. Since then, Heinz has increased its sonic quality in several fundamental revisions for his loudspeaker tweeter designs at ADAM Audio and HEDD.

In 2019 Heinz has started developing a full range Air Motion Transformer to break new grounds for this superior transducer principle. In order to reproduce the complete audible frequency band (and beyond), the HEDDphone® incorporates VVT® technology (Variable Velocity Transform). It introduces a new, variable diaphragm geometry that expands the AMT principle to a linear full range (10Hz–40kHz) headphone transducer.

The HEDDphone® brings the enormous dynamic capabilities and the superior sonic resolution of the AMT principle to the world of top-end headphones. HEDDphone® excels where it really matters: in accurate, untamed, and touching music reproduction.
