Dan Clark Audio ÆON 2 Open-Back Planar Magnetic Headphones

Hear your music breathe: spacious, planar speed in a travel‑ready design

If you love the openness and imaging of true open‑backs but dread heavy, unwieldy planars, the ÆON 2 Open is the antidote. Its proprietary planar magnetic driver delivers fast, low‑distortion transients and an expansive stage, while a patented folding gimbal and 300‑something‑gram build make it remarkably easy to live with at home or on the go. Add Dan Clark Audio’s second‑generation TrueFlow airflow management and V‑Planar diaphragm processing, and you get engaging bass drive, crisp detail, and long‑session comfort—without the bulk.

Why Audiophiles Choose This Product

• • Primary Benefit: Engaging, open‑back sound with real planar punch
  The ÆON 2 Open presents an immersive, wide stage with taut, impactful low end and lively presence—an energetic, slightly V‑shaped balance that many listeners fine‑tune with the included tuning pads or light EQ to taste. Professional comparisons note its mid‑bass warmth and a touch more upper‑mid/treble energy than its closed sibling, trading a bit of sub‑bass weight for air and height.

• • Technical Benefit: Proprietary second‑gen motor for speed and clarity
  DCA’s in‑house 62×34 mm single‑ended planar driver uses V‑Planar diaphragm processing and TrueFlow V2 to reduce turbulence through the motor, lowering distortion and improving microdetail and dynamics. THD is rated under 0.3% from 20 Hz–20 kHz.

• • Practical Benefit: Built to wear—and to travel
  At about 328 g with a super‑elastic NiTi (Nitinol) headband, carbon‑fiber baffle, and cushy synthetic‑leather pads, the ÆON 2 is exceptionally comfortable. The patented folding gimbal collapses the headphone into a compact case that’s half the size of typical full‑sized cans—perfect for desktops that double as travel rigs.

• • Compatibility Benefit: Easy cabling, flexible termination
  Ships with a detachable 2 m dual‑entry cable (3.5 mm plug with screw‑on 6.3 mm adapter), with optional balanced terminations available. The earcups use DCA’s discrete 4‑pin Hirose connectors, making upgrades straightforward. Sensitivity and impedance are rated at 94 dB and 13 Ω, respectively—playable from quality portable sources, yet happiest with solid‑current headphone outputs.

• • Unique Benefit: Patented, portable planar that doesn’t compromise
  Few open‑backs marry true planar performance with a pack‑flat, patented design. The ÆON 2 line has earned sustained industry recognition for its sound, comfort, and engineering.
