The HEDD HEDDphone Headphones redefine what studio headphones can be by delivering the speed, depth, and dimensionality of full-range Air Motion Transformer technology in a mastering-grade open-back design.
Built for engineers, producers, audiophiles, and critical listeners who demand uncompromising detail, the HEDDphone creates an expansive listening experience that feels remarkably close to high-end studio monitors. At the core of the HEDDphone is HEDD Audio’s Variable Velocity Transform (VVT) Air Motion Transformer driver technology, which adapts the legendary precision and transient response of AMT loudspeaker drivers for headphone use. The result is exceptional clarity, ultra-fast transient reproduction, and a highly natural stereo image that makes mix decisions easier and long listening sessions more immersive. From critical mastering work to deep music enjoyment, the HEDDphone delivers stunning accuracy across the entire frequency spectrum. Designed and hand-assembled in Berlin, the HEDDphone combines premium materials with a sophisticated ergonomic structure that balances durability and comfort. The open-back architecture allows the drivers to breathe naturally, creating a spacious soundstage with realistic depth and articulation that traditional dynamic headphone designs often struggle to achieve.
Air Motion Transformer
For the HEDDphone we have developed a new full-range Air Motion Transformer. As opposed to planar, dynamic or electro-static drivers, it is based on a pleated Kapton diaphragm, which is folded into a magnetic field. Air is sucked in and squeezed out in every single fold, accelerating the air significantly. The sonic benefits are a faster transient response and greater treble extension, increasing precision, clarity and ultimately, realism in audio reproduction.
Variable Velocity Transformation
To achieve an even frequency response across the entire audible frequency range, we refined the original design by adding new geometries and a more complex system of variable sized folds. We call this approach VVT – Variable Velocity Transform.
Designed and Made in Berlin
The HEDDphone was developed from scratch in Berlin. Due to the precise folding technique and careful implementation of this unique design, the HEDDphone is handmade with great care and attention to detail like no machine is capable of. All sourced materials are of high quality, like the vegan pleather pads.
