HEDD Audio HEDDphone Two

The culmination of three years of relentless R&D, every aspect of HEDDphone has been refined for an unparalleled audio experience.

By utilising ultra-light materials, such as carbon-fibre and magnesium, we’ve achieved a 25% weight reduction for the HEDD HEDDphone Two. Our newest Air Motion Transformer driver has been reconstructed from the ground up, ensuring that every sonic detail is more vivid and lifelike than ever before.

With its smart strap system, HEDDband® enables you to personalize height, width, curvature, and clamping pressure, to achieve a custom fit that’s comfortable for prolonged use.

Technologies of the HEDDphone Two

Air Motion Transformer

Handmade in Berlin using high quality components, the HEDD Air Motion Transformer of the HEDD HEDDphone Two puts HEDD’s expertise at your disposal to deliver impeccable transient response and ultra-high frequency extension. As a result, high frequencies remain transparent and linear and do not distort natural sound reproduction in any way.


Variable Velocity Transformation

VVT allows the AMT driver in the HEDDphone Two to achieve even frequency response across the entire audio spectrum. This is done by rethinking the driver’s geometry to allow folds to vary in width and depth. The result is the world’s first full-range AMT headphone.



We created HEDDband so that you can forget you are wearing headphones and focus on the music you are creating, or listening to. Our unique design uses a smart strap system that adjusts the shape and tension to comfortably fit heads of any shape or size.
