When every detail matters.
The Hi-X55 is the skilled surgeon of the Austrian Audio headphone line—a mid-forward, closed-back headphone that uncovers every detail in your mix. Our handmade High Excursion Drivers reduce internal resonance and enhance membrane movement to give you a fully honest sonic image.
Since comfort is crucial for critical listening applications, the Hi-X55 is equipped with a pressure-reducing head bow and memory foam earpads that are perfect for strain-free, multi-hour mixing sessions. The Hi-X55 is an essential audio tool for anyone looking to explore and refine their recordings.


Hi-X Technology
Hi-Xcursion (High Excursion) technology drives the remarkable sound of our Hi-X headphones.
- All Austrian Audio Hi-X models feature a 44mm driver and an advanced ring magnet system, delivering superior airflow and the strongest magnetic field in its class.
- The ring magnet, paired with a copper-clad aluminum voice coil, reduces membrane weight for faster, more precise impulse response.
- The 44mm design ensures professional performance, enhanced air movement, and eliminates diaphragm wobble. The ultra-stiff membrane effectively dampens resonance for an ultra-clear and dynamic sound.
