#104 HEDD Heddphone 2 GT: $2,199.00 HEDD $2,199.00 eBay
Pros: A full-range Air Motion Transformer open-back that measures very close to the Harman target (score 82 across four measurements), with full sub-bass to 20 Hz.
Cons: Heavy at 550 g, and its low 88 dB/mW sensitivity needs a strong desktop amplifier. Bass and treble both sit about 1.7 dB below target, a touch lean. See headphone amps and DACs with enough power to drive it.

Frequency Response
How the HEDD Heddphone 2 GT measures across the audible range, against the Harman over-ear target that most listeners prefer in blind tests. Where the line sits above the target that range sounds louder (more bass, brighter treble), below it quieter. The curve is the median of 4 independent measurements, so one odd sample or rig cannot skew it, and both lines are shifted so their 500 Hz to 2 kHz average sits at 0 dB.
Measurement data: median of 4 measurements from the squig.link databases of gadgetrytech, kr0mka, listener and superreview. Thanks to each of them for publishing their work.
