Aune AC55
Open-Back Clip-On Headphones – Reference Class
When clip-ons redefine their limits.
The Aune AC55 elevate the concept of clip-on headphones to an entirely new level. With a reinforced W-shaped bio-fiber composite diaphragm, a specially engineered ultra-elastic long-excursion surround, and a high-dynamic symmetric driver system, they deliver a sound quality far beyond what one would expect from clip-ons. The result: deep, controlled bass, impressive dynamics, and finely detailed treble – a true all-rounder for almost any music genre.
W-Shaped Bio-Fiber Composite Diaphragm
Pure, Authentic Sound
The 40 mm diaphragm offers about 70% more effective vibrating surface than comparable models. The combination of bio-fiber and a thermally stabilized layer increases rigidity, providing clearer and more precise highs. Subtle instrumental nuances and vivid vocal details are reproduced with natural authenticity.
Ultra-Elastic Long-Excursion Surround
Bass That Sets New Standards
The highly flexible surround construction enables exceptionally large diaphragm movement. This allows the AC55 to produce deep, powerful bass – including sub-bass regions that are normally difficult to achieve with open clip-ons. A bass foundation that can easily compete with excellent over-ear headphones.
High-Dynamic Symmetric Driver System
Precision Under Any Load
The optimized driver system provides generous room for voice coil movement. Even with highly dynamic or loud recordings, diaphragm control remains stable and distortion stays low. Every musical nuance is delivered clearly, energetically, and faithfully.
Open Clip-On Design
Wide, Transparent Soundstage
The fully open back allows sound waves to disperse naturally, resulting in a wide, airy soundstage with lifelike spatial imaging. Especially with orchestral music, soundtracks, and film scores, the AC55 impress with depth, layering, and sovereign dynamics
Semi-Memory Earhook
Secure Fit, Superior Comfort
Despite its powerful technology, wearing comfort remains excellent. The specially developed semi-flexible metal earhook adapts to the ear shape, distributes pressure evenly, and ensures a secure, comfortable fit – even during extended listening sessions.
High-Quality Cable with Modular Plugs
Prepared for Any Situation
The high-grade cable with oxygen-free copper conductors and Litz braiding guarantees clean signal transmission. Thanks to the modular plug system, switching between 3.5 mm single-ended and 4.4 mm balanced is effortless – robust, flexible, and compatible with a wide range of devices.
Natural, Balanced, Uncompromising
A Boundary-Breaking Listening Experience
The Aune AC55 transcend the typical limitations of their form factor, delivering exceptional broadband performance, impressive dynamics, and a spacious soundstage rarely found in clip-ons.
A true breakthrough – and a new definition of what clip-on headphones can achieve.
