Band: opinion spread · Dot: weighted average
Sources split: about two-thirds by weight hear a balanced or pleasantly warm, relaxed tuning; a third hear it as dark, muffled and muddy. Both camps describe the same measured shape — more mid-bass, a recessed upper midrange — and differ on whether that is warmth or a veil. Listeners coming from brighter or V-shaped gear land in the second camp most often.
Measured
Four rigs agree on the shape. Against an HD 6XX on the same rig (Audio Amigo, Capra Audio, GadgetryTech): +2.1 to +3.0 dB at 80–150 Hz, −5.3 to −6.1 dB at 1.5–2.5 kHz, −5.3 to −5.7 dB at 2.5–3.5 kHz, and +4.0 to +5.8 dB at 5–7 kHz, with the ear-gain peak at ~6 kHz on all three. RTINGS scores it Bass −1 dB, Treble −2 dB against its target and calls the signature 'Balanced'. DIY-Audio-Heaven measures a ~10 dB slide from 300 Hz to 5 kHz (about 5 dB shallower in practice because of the angled driver).
vs. listeners — RTINGS and DIY-Audio-Heaven read nearly the same curve and reach opposite verdicts: judged against RTINGS' own target it scores 'balanced', while DIY-Audio-Heaven, whose plots read flat as neutral, calls the same upper-mid dip 'overly relaxed'. The split is the reference and the listener's habits, not the unit.
“Their balanced sound profile delivers a somewhat mid-forward tuning with ample boom and mostly clear treble that mostly follows our target, except in the bass.”
