HEDDphone® 2 GT
Hi-Fi-tuned evolution of the HEDDphone 2 platform
First things first with any new headphone: how does it sound? With the second generation, HEDD Audio responded to feedback from customers who found the original HEDDphone too heavy and too large. The HEDDphone 2 is lighter, more comfortable, and highly adjustable. Its original tuning was aimed at studio use, with a neutral profile and a slight emphasis in the midrange.
But if you simply want to enjoy music, that studio tuning may feel a bit too restrained— and that’s exactly why the HEDDphone 2 GT exists.
Optimized for Hi-Fi listening
While the HEDDphone 2 originally shipped with vegan leather pads, the GT now includes two new pad types in the box: genuine leather and velour—both compatible with the HEDDphone 2 as well.
The cable selection has also expanded. Braided nylon cables with 3.5 mm, 6.35 mm, 4.4 mm balanced, and 4-pin XLR balanced are still included. At launch, a premium 4.4 mm cable is available as an optional upgrade, with more to come.

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.
