Astell&Kern AURA Earphones
The Astell&Kern AURA earphone is the first collaboration with high-end earphone manufacturer Vision Ears.
Astell&Kern is always challenging the possibilities of infinite sound and striving for the purest sound imaginable. Wanting to fully convey the groundbreaking sound of the newest flagship A&ultima SP3000, which was created by Astell&Kern’s continued efforts, through the best IEM that deserves it.
Astell&Kern strive to provide the best sound, not overlooking even the most minute differences in sound with by incorporating astonishing technological innovation and craftsmanship. Based on this philosophy, Astell&Kern and Vision Ears joined forces to create AURA.
Vision Ears is a premium German IEM brand established in 2013. They provide some of the the highest-quality IEMs created based on its technological prowess and meticulous craftsmanship by hand, earning it recognition as a leader in the premium IEM market. These two companies are at the forefront of the audio player and IEM market and have joined forces to develop a new IEM based on a profound respect for each other’s values in terms of sound and their outstanding technological competences.
Astell&Kern and Vision Ears share the philosophy of craftsmanship in sound, and with this shared vision, they were able create an unrivalled IEM with outstanding sound quality, integrity, and design that all audio lovers dream of.

Custom Designed 11-Drivers
2 x 8 mm Al-Mg Low Dynamic Drivers– [Sub-low & Low]
The 8-mm isobaric dynamic drivers offer powerful output and precision sound. Two 8-mm dynamic drivers handle the low and mid-low frequency ranges, offering tighter, more precise, and better tuned bass thanks to their exquisite design.
Eight Drivers: Two Sets of Four Balanced Armature Drivers– [Mid-low] [Mid] [Mid-high]It comes with specially selected four mid-low balanced armature (BA) drivers and four mid and mid-high BA drivers with two pairs of dual BA drivers that combine to handle the mid and mid-high frequency range. The carefully selected eight BA drivers work together to create precision mid-range sound and produce warm and emotional male and female vocals.
1 Balanced Armature Super Tweeter– [High & Super High]Balanced armature (BA) drivers designed with to maximize a sense of space and openness are utilized to create soft, delicate, yet expanded ultra-high-frequency sound that resonate richly in your ears.
Ultra-Precision Technology
5-Way Crossover
The Astell&Kern AURA technical configuration is designed with a 1st grade crossover, meticulously manufactured in Germany. All components being well chosen for lowest tolerances possible on the market. AURA is using a 5-way crossover with a particular circuit solution that avoids an excessive load from the tweeter towards the source (amplifier), thus reducing distortion and extending the reproduction of high frequencies. Internal wiring is made with premium silver plated copper alloy wire for highest performance.
Isobaric configuration with two dynamic drivers
Two 8mm dynamic drivers are placed facing each other in an isobaric configuration. As two drivers are placed facing each other and the sound is output from exactly between them, the compositional interference is maximized, effectively doubling the output volume. This, in turn, removes any phasing issues that may raise from the length difference between the sound tubes, reducing THD.
This design makes the low-frequency sound created by the dynamic drivers more accurate, solid, and vibrant.

Chamber
The “special chamber” have a precise internal volume that has been calculated to get the best compromise between driver speediness and musicality. The two DD Drivers are strictly matched to reduce any possible phase incoherence which could lead to inaccurate transient reproduction.
Mesh
AURA’s open-structure design features a vacuum metal mesh that gleams elegantly on top. This special aluminium acoustic mesh circulates air from the dynamic driver to control the powerful resonating force, protecting internal components from external influences.
Material Innovation and Craftsmanship
The front plate and shell of the Astell&Kern AURA is made from Swiss 6061-T6 aluminium.
Aluminium 6061 is an alloy that is lightweight, sturdy, and highly resistant to corrosion. On top of that, we added T6 heat treatment to enhance the strength of the aluminium, making it not only feather-light and sturdy but also allowing it to be given a beautiful finish.
Production processes of all parts are done through the highest-quality CNC milling process, one part at a time.
The Micro Groove Design Faceplate
The Micro Groove Design is applied with surface treatment for milling process. Grooves are dug along the grain of the raw material to create a unique design, before the product is moved to a precision-tailored jig for laser engraving. This process is not just a standard laser process but a special laser process that eliminates parts of the raw material to engrave letters 0.5 mm deep while adding depth to the engravings. Next, the component is treated with oil to prevent oxidation, packaged, anodized, and given a custom dark bronze colour.
Precision-Milled Aluminium Shell
Unlike the faceplate, the shell is oil-sealed and then handed to the polishing master. The faceplate is engraved with an aesthetic design element, and the surfaces of shells are polished through a special sand-blast refinement process. Otherwise, marks will be left from the tools used, so each shell is polished like mirror by hand. Then, after sand-blasting and anodizing, the shell is ready to be given Vision Ears’ custom warm grey colour.
The AURA shell is the result of thousands of hours of work, including cutting diamonds out of rough rocks with carefully selected materials, precision processes, and specialised tools.
Effect Audio Custom Cable
The cables that come with the Astell&Kern AURA are custom-made cables from Effect Audio that are specifically designed to deliver the overwhelming sounds of Astell&Kern AURA.
The custom cables contain four wire components: two UP-OCC pure copper litz wires and two pure silver litz and pure copper litz hybrid wires to offer you the best sound performance.
On top of that, Effect Audio’s EPO (Ergonomic Performance Optimization) technology is applied to offer outstanding flexibility for a more comfortable fit without affecting audio quality.
