Short answer: the Audio-Technica ATH-ADX5000. It ranks #22 of 481 over-ear headphones by sound quality, rated 4.3/5, at $2,199; the HEDD Heddphone 2 GT ranks #107, rated 4.0/5, at $2,199. With prices this close, go by the sound-quality ranking rather than the cost.
The case for the Audio-Technica ATH-ADX5000: A preference score of 89 with a perfectly neutral tilt reflects a balanced tuning, with bass and low mids within about 0.7 dB of target. Watch for: The 420 ohm impedance calls for a dedicated headphone amplifier, because a phone or dongle will struggle to drive it to a satisfying volume.
The case for the HEDD Heddphone 2 GT: 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. Watch for: Heavy at 1.2 lbs (550 g), and its low 88 dB/mW sensitivity needs a strong desktop amplifier.
Buy the Audio-Technica ATH-ADX5000. It is rated higher for sound quality than the HEDD Heddphone 2 GT at the same price, so it is the default pick unless a specific strength of the other one matters more to you.
