Oskar Heil’s folded AMT or Air Motion Transformer is well-known for its use as the tweeter in certain speaker models, most famously ADAM Audio products. Designer Karl Heinz’s refinement of the original concept has also been seen in speakers made by his latest company, HEDD Audio. Now Karl Heinz has applied the concept to headphones for the first time, creating a linear full-range (10Hz–40kHz) headphone transducer, the VVT, and crafting the new HEDDphone One. Available in the Autumn, the new headphones are set to retail for under 2000 Euros.
