Band: opinion spread · Dot: weighted average
Broadly neutral with the HIFIMAN signature: flat, deep bass, a midrange dip around 1.5–2 kHz and an elevated top end. Labels range from 'balanced' and 'natural' to 'slightly U-shaped' or 'neutral-bright', but they describe the same curve; it is less forgiving of bright recordings than warmer sets, and reads warmer than the Ananda and Arya.
“open and airy but well-balanced tuning leaning ever-so-slightly to the bright side, with the typical Hifiman dip at around 1-3khz making mid-range instruments less forward or aggressive.”

Measured
On 15 rigs diffed against the same rig's HD 600: level from 100 Hz to 1 kHz, −2 to −5 dB at 1.5 kHz, +3 to +9 dB at 7–8 kHz and a ~12 kHz peak. RTINGS (B&K 5128) labels it 'Bright' with bass −1 dB and treble 0 dB against its target; oratory1990's GRAS curve sits within ±2 dB of Harman from 200 Hz to 6 kHz apart from −3 dB at 1.5–2 kHz.
