HEDD Audio HEDDphone® TWO

The HEDD Audio HEDDphone® TWO is the flagship reference headphone, featuring an innovative approach to electrostatic technology. This second generation of HEDD's award-winning HEDDphone series features a completely redesigned Air Motion Transformer (AMT), combined with HEDD's proprietary Variable Velocity Transformation (VVT) . This technology accurately reproduces frequencies from 10 Hz to 40 kHz , with a dynamic range and openness rarely found in headphones. The HEDDphone® TWO delivers a remarkably natural and balanced soundstage, with stunning transient response, authentic timbres, and a spatial experience beloved by music producers, mix engineers, and audiophiles.

VVT technology gives the AMT driver variable fold depths and widths, resulting in consistent frequency response across the entire audio spectrum. This ensures that every nuance, from the deepest bass to the highest, airy notes, is reproduced with astonishing precision. This technology makes the HEDDphone® TWO the world’s first full-range AMT headphones , a groundbreaking achievement in the audio world. Users like Romesh Dodangoda (known from Bring Me The Horizon and Motörhead, among others) praise not only the sound quality but also the comfort and high-quality workmanship.

The design also focused on comfort and durability. The HEDDband is a modular and fully adjustable headband system that adapts to any head shape. The clamping pressure, curvature, width, and height can be precisely adjusted to the user, allowing for extended wear without pressure points or fatigue. The soft ear cushions and headband are covered in luxurious leatherette and feel comfortable, even during long mixing sessions or listening sessions.

Lightweight yet robust materials such as magnesium and carbon fiber were chosen for the housing, reducing weight without compromising rigidity or resonance control. The HEDDphone® TWO comes with a comprehensive set of high-quality accessories, including two detachable cables (a standard 6.35 mm and a balanced 4.4 mm), adapters (including XLR), and a sturdy carrying case. Each unit is assembled by hand in Berlin , with the utmost care for quality, finish, and audiophile performance.
