HEDD Audio HEDDphone TWO

A new chapter in headphone technology

HEDD is proud to introduce the first full-range Air Motion Transformer headphones for audiophiles and studio artists. The Air Motion Transformer (AMT) is an electrodynamic transducer that makes it possible to move air significantly faster than the known voice coils, magnetostatic (flat) or electrostatic systems. The traditional piston-like movement is maximized by a folded diaphragm that squeezes air out four times faster: a revolution for reproducing and playing back more detail in an audio recording, and you can hear it.

30 years ago, HEDD CEO and Chief Engineer Klaus Heinz designed the first compact and salable AMT tweeter based on Oskar Heil’s original Air Motion Transformer invention. Since then, he has made great strides and improved audio quality in several fundamental revisions. The 2019 version of the AMT can be heard in HEDD’s innovative ONE studio monitor line.

Recently, Heinz has focused on developing a full line of Air Motion Transformers to explore new possibilities for this superior transducer principle. To reproduce the entire audible frequency band (and beyond), the HEDDphone Two contains VVT® (patent pending). VVT® introduces a new diaphragm geometry that extends the AMT principle to full-range linear headphones (10Hz-40kHz). It replaces the fixed geometric structure of conventional AMT drivers because the folds vary in both width and depth.

The HEDDphone TWO introduces a fourth transducer technology. It brings the tremendous dynamic capabilities and superior sonic resolution of the AMT principle to the world of premium headphones. HEDDphone® excels where it really matters: in accurate, untamed and moving music reproduction.
