The "Grand Touring" Philosophy in the HEDDphone Lineup
The HEDDphone TWO GT retains the analytical clarity and precision of the HEDDphone TWO but adopts a "Gran Turismo" approach: more forgiving, more musical, and designed for long listening pleasure. This GT version is not only about monitoring performance; it also aims for a high-end experience in both sound reproduction and ergonomics, while preserving the AMT DNA derived from HEDD's expertise.Who Is It For and What Are Its Uses?
The HEDDphone TWO GT is aimed at producers, mixers, and audiophiles seeking a premium open-back headphone capable of revealing micro-details without causing fatigue. In the studio, it is perfectly suited for balance, panning, and depth work thanks to an "effortless" soundstage. At home, it becomes a reference headphone for rediscovering albums, enjoying dynamic playback, and immersing in long, comfortable, and emotional listening sessions.AMT Technologies and Comfort: Key Evolutions of the TWO GT
Full-range AMT and oversized Kapton diaphragm
At the heart of the TWO GT is a full-range Air Motion Transformer with a multi-layer Kapton diaphragm, claimed to be more than three times larger than traditional dynamic, planar, or electrostatic designs. The result: fast transients, excellent texture clarity, and a very natural sense of space from the low end up to the high frequencies.More musical tuning with air-compliance tuning
This GT edition introduces a tuning system oriented towards "pleasure": more physical bass, warmer midrange, and sparkling treble. The goal is to maintain precise detail retrieval while adding density and roundness that facilitate long listening sessions and make the headphone more tolerant depending on recordings and masters.Long-duration comfort and premium finish
The clamping force has been specifically reworked on the carbon fiber headband, complemented by an adjustable double strap system to better distribute weight. Two pairs of ear pads are included (velour and sheepskin leather) to adapt the feel to wearing comfort and perceived sound. The cables, made of high-purity silver-plated copper with nylon braiding, enhance the premium impression right out of the box. Each headphone is assembled in Berlin and can benefit from a limited 5-year warranty after registration.Technical specifications
