HEDD Audio HEDDphone TWO GT UNPLUGGED

The HEDD Audio HEDDphone TWO GT UNPLUGGED is the cable-free configuration of the HEDDphone TWO GT — the same open-back, over-ear audiophile headphone with warmer tuning, updated AMT driver, and premium materials, supplied with a carry case and a single pair of ear pads for those who prefer to use their own cable. The AMT driver features a 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 HEDDband system adjusts height, width, curvature, and clamping pressure independently for a secure, comfortable fit across extended sessions.

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.
• Interchangeable Ear Pads: One set of ear pads is included. Additional lamb leather and velour pad options are available separately and can be swapped to alter acoustic character and wearing comfort based on preference.
• 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.
• Visual Updates: Embossed logo and stitching details on the HEDDband distinguish the GT with considered aesthetic refinements alongside the acoustic and ergonomic upgrades.
• Includes Carry Case: Ships with a sturdy carry case and one pair of ear pads. No cables are included — compatible with any standard 3.5mm headphone cable.
• Handmade in Berlin: Each HEDDphone TWO GT UNPLUGGED is built with high-quality, durable components and backed by a 5-year warranty after registration.
