HEDD Audio HEDDphone TWO GT

The HEDD Audio HEDDphone TWO GT is an open-back, over-ear headphone built on the HEDDphone TWO platform and refined specifically for audiophile listening enjoyment — a warmer tuning, updated Air Motion Transformer driver, and premium materials chosen as much for comfort and longevity as for acoustic performance. The AMT driver features a new multi-layered Kapton polyimide diaphragm with Variable Velocity Transformation (VVT) for even frequency response from 10 Hz to 40 kHz, with measurably lower distortion than its predecessor. Carbon fiber and magnesium construction keeps weight to 1.2 lbs while HEDD’s adjustable HEDDband system fits heads of any shape, and two sets of interchangeable ear pads — lamb leather and velour — let listeners match the acoustic character and feel to the session. The HEDDphone TWO GT is also available in an UNPLUGGED configuration, which includes the headphone, a carry case, and a single pair of ear pads without cables.

Key Features

• Updated AMT Driver with Multi-Layered Kapton Diaphragm: Handmade in Berlin, the revised Air Motion Transformer features a multi-layered Kapton polyimide film diaphragm that achieves even lower distortion than the original HEDDphone TWO while preserving the AMT’s characteristic precision and transient speed.
• Variable Velocity Transformation (VVT): A HEDD innovation that rethinks AMT driver geometry — varying fold width and depth across the diaphragm — to achieve even, flat response across the full audio spectrum from 10 Hz to 40 kHz.
• Warmer Tuning: The GT’s voicing is calibrated for music enjoyment rather than clinical studio reference, combining the AMT’s inherent detail and speed with a more musical, emotionally engaging tonal character.
• HEDDband Adjustable Headband: HEDD’s innovative strap system adjusts height, width, curvature, and clamping pressure independently, distributing weight evenly and accommodating heads of any shape or size for extended, fatigue-free listening.
• Dual Interchangeable Ear Pads: Two sets of soft ear pads — real lamb leather and velour — are included and can be swapped to alter both acoustic character and wearing comfort based on preference or session length.
• Lightweight Premium Construction: Carbon fiber and magnesium components minimize weight to 1.2 lbs while providing the structural durability expected of a long-term listening instrument.
• Premium Cable Package: Includes a hand-braided, nylon-woven 4-core 5N SPC cable (1.6m) in both balanced (4.4mm Pentaconn termination) and unbalanced (6.35mm termination) configurations, with adapters for 3.5mm and XLR 4-pin. An 8-core LC OFC upgrade cable is available separately.
• UNPLUGGED Configuration Available: The same HEDDphone TWO GT without cables and with a single pair of ear pads, for listeners who prefer to use their own cable or simply want the core headphone.
• Visual Updates: Embossed logo and stitching details on the HEDDband distinguish the GT with considered aesthetic refinements alongside the acoustic and ergonomic upgrades.
• Handmade in Berlin: Each HEDDphone TWO GT is built with high-quality, durable components and backed by a 5-year warranty after registration.
