HEDD HEDDphone TWO GT Open-Back Headphones

The HEDDphone TWO GT open-back headphones translate HEDD’s professional AMT headphone platform into a refined listening experience for serious music enjoyment. Based on the HEDDphone TWO, the GT version adds a warmer tuning, updated Air Motion Transformer driver and multi-layer Kapton polyimide diaphragm designed for lower distortion. Its open-back, over-ear design supports a spacious presentation, while Variable Velocity Transformation technology extends the driver’s range from 10Hz–40kHz. With swappable leather and velour ear pads, premium balanced and unbalanced cables, and HEDD’s adjustable HEDDband system, the HEDDphone TWO GT is built for listeners who want high-resolution detail, fast transient response and a smoother, more immersive sound for focused music listening.

Air Motion Transformer Detail and Speed

At the center of the HEDDphone TWO GT is HEDD’s full-range Air Motion Transformer driver, a design created to deliver fast transient response and an open, highly detailed sound. The GT version uses an updated multi-layer Kapton polyimide diaphragm, which is designed for even lower distortion than the standard HEDDphone TWO driver. HEDD’s Variable Velocity Transformation technology reshapes the driver geometry by varying the folds in width and depth, helping the headphone reproduce frequencies across a wide 10Hz–40kHz range. The result is precise detail retrieval, clear instrument separation and the quick response expected from a high-end AMT headphone.

Tuned for Musical Enjoyment and Long Listening Sessions

While the original HEDDphone TWO is positioned for professional production, mixing and mastering, the HEDDphone TWO GT is tuned with music lovers in mind. Its warmer voicing is intended to balance precision with a richer, smoother listening character, making it well suited for long sessions where emotional connection matters as much as technical resolution. The open-back design adds a spacious feel, while the AMT driver preserves the speed and clarity that define the platform. For critical playback or immersive music listening, the GT tuning gives this headphone a more engaging personality.

Adjustable Comfort With Premium Materials

The HEDDband system gives the HEDDphone TWO GT a highly adjustable fit by letting users fine-tune height, width, curvature and clamping pressure. This design helps distribute the headphone’s 550 g weight more evenly while accommodating different head shapes and listening preferences. Two sets of soft ear pads—real leather and velour—are included, allowing users to change the feel of the headphone as needed. Carbon-fiber and magnesium components help reduce weight while supporting long-term durability, and embossed logo details and HEDDband stitching add a refined visual touch.

Built for Serious High-Resolution Listening

The HEDDphone TWO GT includes a sturdy travel case, a 1.6 m unbalanced cable with 6.35 mm termination, a 6.35 mm to 3.5 mm adapter, a 1.6 m balanced cable with 4.4 mm termination and a 4.4 mm to XLR 4-pin adapter. As a passive headphone, it requires a dedicated headphone output, with HEDD recommending at least 200 mW at 40 ohms and preferably 1000 mW or higher for best performance. Designed and assembled in Berlin, the HEDDphone TWO GT Open-Back Headphones combine innovative AMT technology, premium comfort and refined tuning for an immersive high-resolution listening experience.
