HEDD HEDDphone TWO Open-Back Headphones

The HEDDphone TWO open-back headphones represent the culmination of three years of refinement driven by extensive research, development and user feedback. Designed for audio professionals and anyone serious about sound, the HEDDphone TWO builds upon HEDD’s innovative Air Motion Transformer platform with improvements to comfort, adjustability and overall sonic performance. Its refined AMT driver and Variable Velocity Transformation technology deliver exceptional detail, natural timbre and extended frequency response, while the redesigned HEDDband system allows users to tailor fit and clamping pressure for long sessions. The result is a pair of professional open-back headphones engineered for critical listening, mixing, mastering and reference-quality music playback.

Air Motion Transformer Accuracy and Transparency

At the heart of the HEDDphone TWO is a refined Air Motion Transformer driver featuring HEDD’s Variable Velocity Transformation technology. By varying the width and depth of the driver folds, VVT enables even frequency reproduction across a remarkably wide 10Hz–40kHz range. The design delivers exceptional transient response, extended high-frequency performance and accurate timbre, helping preserve the natural character of instruments and recordings. Handmade in Berlin using high-quality components, the AMT driver provides the openness, speed and transparency that have made HEDD headphones a trusted tool among discerning audio professionals.

Built for Critical Listening and Production Work

The HEDDphone TWO is designed to help engineers, producers and serious listeners hear deeper into a mix. Its open-back architecture creates a spacious, natural presentation that supports accurate monitoring and precise evaluation of recorded material. Fast transient response and detailed instrument separation make it easier to identify subtle changes in dynamics, balance and tone, while the headphone’s natural sound signature avoids exaggerating any particular frequency range. Whether used for music production, mixing, mastering or focused listening, the HEDDphone TWO provides a reliable reference for informed audio decisions.

Adjustable Comfort for Extended Sessions

The HEDDband system allows users to adjust height, width, curvature and clamping pressure for a personalized fit that remains comfortable during long sessions. Carbon-fiber and magnesium components help reduce weight while maintaining durability, and faux leather ear pads and a matching head cushion provide lasting comfort. The HEDDphone TWO includes balanced and unbalanced 2.2 m cables, 3.5 mm and XLR adapters, a spare set of ear pads and a travel case for storage and transport. Designed for audio professionals, engineers and listeners who prioritize accuracy and detail, the HEDDphone TWO open-back headphones combine innovative AMT technology, precise sound reproduction and long-session comfort in a reference-quality monitoring platform.
