HEDDphone® TWO GT UNPLUGGED
Engineered for those who know exactly what they want
The HEDDphone® TWO GT UNPLUGGED delivers the same reference-grade performance based on HEDD’s full-range Air Motion Transformer (AMT) technology — intentionally supplied without a cable.
Designed for experienced audiophiles and professionals who already own their preferred cables, this version removes redundancy and offers complete freedom of connection. No shortcuts, no hidden compromises — just the headphone in its most direct and distilled form.
The UNPLUGGED Edition is ready to meet your system on your terms.
HEDDphone® TWO GT
Developed with the audiophile world in mind, the HEDDphone® TWO GT is designed for musical enjoyment rather than analytical studio monitoring.
Based on the acclaimed HEDDphone® TWO, several key elements have been refined: a warmer tuning that balances precision and emotion; an updated AMT driver with even lower distortion; enhanced visual detailing on the logo and HEDDband stitching; and improved comfort through premium velour earpads.
The result is a richer, smoother yet still exceptionally fast and detailed sound, paired with an innovative ergonomic design for a luxurious listening experience.

Measurements
Frequency response
What does this mean?
The line marked as target is something you could call the “ideal” curve: a target response derived from research by the Harman group, exploring what kind of headphone tuning tends to be preferred by a broad range of listeners – regardless of age or demographics. This is often referred to as the Harman Target.
From left to right you see sub-bass, bass, mids, and then the curve tilts upward where treble begins. That part of the spectrum is naturally amplified by the shape of the human ear.
Sub-bass sits on the target, the bass is slightly elevated. The lower mids are neutral, the presence region around 3 kHz hits the target. The treble is slightly tuned more relaxed – never sharp, easy over long sessions, above 10 kHz there is a little extra air. Left and right channels track each other closely, a sign of careful driver matching.
