Delightfully revealing

We created our new Hi-X65 open-back headphones with mixing and mastering in mind. They’re built to satisfy the need for close, precise listening at these critical stages of the audio production process.

The same qualities that make them great for professional audio production also make them perfect for audiophiles who appreciate hearing every shade of nuance in the music they love.

High Precision meets pure Enjoyment.

Hi-X65 headphones are built around a driver that was first designed with open headphones in mind, and listening to them is like opening a new window on your music. The open-back design brings a natural and spacious sound, giving new clarity to the placement and character of its individual elements.

Hi-X65 headphones provide a high-resolution, precise aural perspective and a critical new tool for professional mixing and mastering.

Made in Austria.

You’ll understand the quality of your new Hi-X65 headphones the moment you take them out of the box, before you’ve even listened to the first note. They feel great in the hand and great on your ears, and the build quality is exceptional, as you would expect. The Hi-X65 headphones are designed, engineered, and manufactured in Austria by a team of passionate experts with long experience in crafting high-quality microphones and headphones for demanding audio professionals.

Of course, the final test of quality is in the listening. Put the headphones on, turn on your music, and experience for yourself the clarity and precision of Hi-X technology in an open-back design. You’ll hear exactly what we mean.

Recording Magazine
Toller Einstieg! Der Austrian Audio Hi-X65 verbindet langjähriges Knowhow im Kopfhörerbau mit frischem Denken, liefert einen extrem sauberen Klang auf Referenz-Niveau und punktet mit gutem Design und hochwertiger Verarbeitung
If you can afford a pair of headphones solely for mixing and critical listening then the Hi-X65 ticks a lot of boxes.
They sound clean, they present the full frequency spectrum, they have a wide but not exaggerated soundstage
I understand that the Hi-X65 was designed to be used as a tool for mixing and mastering. However, I can confidently say that it can also create an enjoyable listening experience because of its slightly richer presentation while managing to remain reliably neutral and highly detailed.
Mehr Präzision und Feingefühl als fast jeder Hi-Fi-Hörer, [den ich je hatte], einige doppelt so teuer wie der Hi-X65
With amazing transient response and an immersive stereo field, these open-back headphones are hard to beat for critical edits, checking mixes/masters and unbridled enjoyment of your favourite pre-recorded music.
Der Austrian Audio Hi-X65 ist für den aufgerufenen Preis von 349,-€ nicht nur ein Klang-Profi für das Tonstudio. Der Hi-X65 gefällt mir aufgrund seiner Abstimmung und universelleren Nutzung über alle Genres hinweg bisher am besten und spielt zudem auch deutlich oberhalb seiner Preisklasse. Ein rundum toller Kopfhörer!
Es dürfte sehr schwer sein, zu diesem Preis einen besseren offenen Kopfhörer zu finden.

High Excursion Technology

Hi-Xcursion (High Excursion) technology is the key to the astonishing sound of our Hi-X65 headphones.

All Austrian Audio Hi-X headphones feature a 44 mm driver and a ring magnet system. This design allows for improved airflow and includes the strongest magnetic field in its class.
The ring magnet, combined with a copper-clad aluminum voice coil, reduces the weight of the membrane and the voice coil connected to it, allowing the membrane to move or change direction faster, providing a more responsive impulse reaction.

Our science, measurements, and listening tests have shown that 44mm is the optimum size for this design. It ensures professional performance in the Hi-X, moves a lot of air, and eliminates ‘wobbling’ of the diaphragm. This is akin to damping of the driver mass, which is where our membrane really shows results: it is ultra-stiff while still reducing unwanted resonance.
