A compact, foldable closed-back planar-magnetic headphone that brings Dan Clark Audio's AMTS tuning down to $999. Reviewers broadly agree on several things: it's exceptionally comfortable (a light-ish ~385–403 g with a self-tensioning headband, though clamp runs medium-strong), beautifully built from premium materials (Gorilla Glass, Alcantara, nitinol) if a fingerprint magnet, and tuned close to the Harman target with a lively bass-and-treble lift rather than strict neutrality. Its imaging is near-universally praised as precise, and for a closed-back it isolates well. Measurements agree on the shape: a flat 13 Ω / ~94 dB/mW load, a sub-bass bump near 100 Hz, a presence bump around 2 kHz and elevated upper treble. The real arguments are about how that lands. The bass splits between listeners who hear it as clean, punchy and well-extended and those who find its slam modest for the price and dependent on a perfect seal (or a little EQ). The top end splits between those who hear a refined, well-controlled sparkle and those for whom the boost reads bright enough to fatigue — a divide most tie to individual HRTF and the AMTS. The soundstage splits between open-and-wide-for-a-closed-back and intimate/narrow. Drivability is contested too: on paper an easy load, but several owners and reviewers say it 'craves power' and clearly prefers a real desktop amp. Value is strong at $999 by most accounts — a benchmark under $1k — with the caveat that the pricier DCA E3 remains the better set for bass slam and smoothness, and a few listeners prefer the cheaper, older Aeon 2 Noire.
About this product
Ported closed-back over-ear with a 62 × 34 mm single-ended planar-magnetic driver and DCA's programmable AMTS (Acoustic Metamaterial Tuning System). A flat 13 Ω load rated ~90 dB/mW and 403 g (reviewers measure ~94 dB/mW and ~385 g), with Gorilla Glass cups, a self-tensioning nitinol headband and Alcantara/protein-leather pads; foldable. It's the AMTS-equipped successor to the original AEON Noire (~327 g, $899, tuning-pad tuning) and sits below the pricier DCA E3 and STEALTH. Not the newer Noire XO, and not the older Aeon 2 Noire / Aeon 2 Closed it's often shopped against. Sometimes styled 'Aeon Noire X.'
Dan Clark Audio's Noire X is the closed-back that finally brought the company's flagship AMTS tuning tech — first seen in the four-figure STEALTH — down to a $999 price. It replaces the original AEON Noire's swappable tuning pads with a fixed, programmable acoustic filter, wraps a 62 × 34 mm planar driver in Gorilla Glass cups and a self-tensioning headband, and folds down smaller than almost anything in its class.
The pitch is a genuinely portable, closed-back planar tuned close to the Harman target but with a lively bass-and-treble lift for excitement rather than dead neutrality. It has drawn glowing reviews and a few pointed dissents — over whether the bass really slams, whether the bright top end fatigues, how big it sounds, and how much amplifier it truly wants — which makes it a good candidate for reading the consensus rather than any single verdict.
