Despite being designed by a relatively new company, the Hi-X55 is a very mature product that shouldn’t just be confined to the studio. Plenty of regular audiophiles will enjoy this also.
That precision and snap continues elsewhere in the sonic range. The treble and midrange are clean, crisp and detailed, and everything is fairly even across the spectrum.
What Hi Fi?
If you want to hear the finest details of a mix but don’t want to be bored rigid as you do so, the Austrian Audio Hi-X55 are what you need.
Audio Media International
From the classy design, innovative technology, and high-end materials, it’s obvious that these Hi-X55 headphones are built to last.
The Hi-X55 is an excellent foray into the headphone market by Austrian Au-dio. The comfort and build quality are top-notch, and the sound is tight through-out the spectrum with a very detailed upper midrange.
Recording Magazine
In terms of signal dynamics, these headphones really make a big splash. Especially the low-frequency transients, which are reproduced with a lot of punch and thrust.
The same classy pedigree and thoughtful design that went into Austrian Audio's OC mics is apparent in their first headphones too.
Sound On Sound
Austrian Audio has created a superb set of headphones in the Hi-X55s. Their sound-for-pound cannot be faulted and, in many respects, especially with regard to the capacious soundstage, they outperform some more costly designs.
In Sachen Signaldynamik machen diese Headphones ordentlich Dampf. Insbesondere tieffrequente Transienten bilden sie druckvoll und mit viel Schub gekonnt ab. Auch die akustische Isolation nach außen und die Dämpfung von Außengeräuschen sind den Entwicklern gelungen.
Mit dem Over-Ear-Kopfhörer Austrian Audio Hi-X55 liegt ein eindrucksvolles Debüt vor, das in vielen Punkten Bestnoten einheimsen kann.
Mobilefidelity Magazin
Aus meiner Sicht ist er einer der besten Kopfhörer für einen Preis von unter 300€ und das sogar, ohne dass auf audiophile Ansprüche verwiesen und ohne, dass er mit Superlativen beworben wird. Ein Studio-Kopfhörer, der gekonnt in die akustische Trickkiste greift und keine Details vermissen lässt…
Als Studiokopfhörer beweist er wahre Monitorqualitäten und ist ein überaus präzises Werkzeug für die Arbeit im Studio oder unterwegs. Als vorwiegend audiophil genutzter Kopfhörer überzeugt er durch einen linearen Frequenzverlauf, der für alle Musikarten gleichermaßen gut geeignet ist.

High Excursion Technology

Professional Headphones

Hi-Xcursion (High Excursion) technology is the key to the astonishing sound of our Hi-X55 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.
