Band: opinion spread · Dot: weighted average
Sources split, and the split is about consequence rather than fact. Every rig puts the ear-gain peak near 3.4 kHz, a little later than usual, with 1–2 kHz sitting slightly low. A majority of sources — now including two French labs, a long-form video reviewer and the headphones.com reviewer who named it his headphone of 2024 — hear that as natural, rich, unforced vocals with none of the lower-midrange suckout typical of closed-backs. A substantial minority hear the same peak as shout, glare or breathy, slightly distant voices, especially at high volume; several owners returned it for exactly this. Owners who swapped pads or got a better seal report the glare going away.
Measured
Eleven squig rigs and oratory1990's GRAS agree on the shape: 1–2 kHz sits 1–3 dB under the HD 600 on the same rig, the ear-gain peak lands at about 3.4 kHz (2.7–3.5 kHz depending on rig), and 5 kHz dips 3.5–7.5 dB. Against Harman 2018 oratory1990 reads −1.8 dB at 2 kHz and +0.8 dB at 3.5 kHz — a small deviation. Fc-Construct identifies the shifted peak as the cause of the 'roller-coaster' look, Resolve hears a hint of glare, and Kuulokenurkka finds a slight cut at 3.5 kHz makes it natural again. RTINGS scores the mids close to its target.
vs. listeners — Two things explain why the same curve reads so differently. First, the open Hadenys — which measures 2–4 dB hotter from 3.5 to 6 kHz on the same rigs — carries more 1–1.5 kHz energy, which Kuulokenurkka and Fc-Construct independently say masks its peak; the Azurys' leaner 1–2 kHz leaves its smaller peak more exposed. Second, the band is fit-dependent: Griffin Silver measured that more clamp brings more lower midrange and less treble, and owners who changed pads (W9W, Fatsosixsixsix) or got a better seal on a second unit (Maukey) report the glare gone.
“La qualité des voix est excellente, sans agressivité ni sensation de manque.”
Les Numériques (Guillaume Fourcadier) — 'vocal quality is excellent, with no aggression and nothing missing'
“a vocalist might sound somewhat frail and distant with Azurys”
Kuulokenurkka (Headphone Corner)
