The Heddphone shows that it is worthwhile to continue to question the conventional design principles of driver construction. With a retail price of 1,698 Euros, the debut product from HEDD Audio immediately ranks in the top class of headphones. The sound performance on offer means it can even compete with more expensive products. In terms of speed, transparency, spatial imaging and dynamics, this product of Berlin developers sounds simply superb, assuming that you are using a high-performance headphone amplifier. But the developers’ decades of experience and their will to achieve top-class performance are also evident in the other evaluation categories. The Heddphone is both an amazing sound engineering tool and a headphone that should cause celebration among audiophile music lovers. Personal taste will be the deciding factor with regard to their bulky appearance and weight, but under no circumstances should you miss the chance to try them out.
