(SHIPPING AUGUST 2026) Aune AR9000 Open-Back Headphone (Call/Email For Availability)

Loudspeaker-scale sound, without needing a room built around it.

Headphones.com called it "a formidable contender in the $1,500 bracket" that rivals established flagships.

The best open-back headphones try to disappear and let you forget you're wearing headphones at all — to sound like a great pair of speakers in a great room, not like something clamped to your head. That's the exact goal behind Aune's flagship: a 50mm dynamic driver engineered with the kind of design principles borrowed from high-end loudspeakers, built to deliver real dynamic scale and space rather than a compressed, headphone-shaped version of it.

The heart of that is Aune's Omni-Stack Carbon Diaphragm — continuous carbon fiber layers stacked at precise angles with zero cross-weave, giving it a stiffness-to-density ratio that beats typical ceramic, metal, or coated polymer diaphragms, so fine detail stays crisp instead of blurring under stress. Pair that with up to 4mm of linear driver excursion — enormous by headphone standards — and you get bass that actually moves air and holds together through big dynamic swings, instead of thinning out the moment a track gets demanding. A newly engineered acoustic chamber system tames the reflected sound waves in the rear cavity for a wider, more natural soundstage, and an all-metal headband plus a modular 8-core silver-plated OCC copper cable (3.5mm, 6.3mm, 4.4mm, and XLR terminations) round it out as a genuinely complete flagship package.

If you've been chasing headphones that actually sound like a serious speaker system, this is Aune's answer to that chase.
