Austrian Audio Hi-X65 Studio Headphones

Austrian Audio Hi-X65 — Open-Back Reference Headphones for Mixing and Mastering

The Austrian Audio Hi-X65 is a professional open-back over-ear headphone built for engineers, producers, and critical listeners who need an honest window into their audio. Powered by a 44 mm High-Excursion driver paired with a copper-clad aluminum voice coil and an advanced ring magnet system, this model reproduces the full audible spectrum from 5 Hz to 28 kHz with controlled transients and minimal distortion. The open-back architecture opens up a wide, natural soundstage, letting every element in a mix sit in its own clearly defined space.

For studio professionals and creators who demand reference-grade accuracy, the Hi-X65 provides a neutral response without the hype or coloration that masks mix decisions.

What Sets the Hi-X65 Apart

At the heart of the Hi-X65 sits Austrian Audio's proprietary Hi-Xcursion (High-Excursion) technology, a 44 mm driver design with an advanced ring magnet system that produces the strongest magnetic field in its class while improving airflow around the diaphragm. The copper-clad aluminum voice coil reduces moving mass for a faster, more precise impulse response. An ultra-stiff membrane dampens unwanted resonance. All key components — from ear pads to cables — are replaceable, extending the product's working life in demanding studio environments.

Driver Technology — Fast, Honest, and Revealing

When mixing, the driver determines whether a track will translate across systems. The Hi-X65's 44 mm High-Excursion design is engineered to expose flaws rather than flatter them. The ring magnet system delivers superior airflow and a strong magnetic field, while the copper-clad aluminum voice coil keeps the membrane light for immediate transient response.

• Driver Size: 44 mm — large diaphragm for enhanced air movement and reduced wobble
• Sound accuracy is boosted by the copper-clad aluminum voice coil, providing low moving mass for fast, precise impulse response.
• THD (@ 1 kHz): <0.1% — clean playback that reveals mix problems without adding distortion
• Sensitivity: 110 dBspl/V — efficient output for use with portable and interface sources

Frequency Response and Electrical Specs — Reference Accuracy

A reference headphone needs to cover the full audible spectrum without artificial emphasis, and the Hi-X65 reaches from sub-bass to upper treble with a neutral, controlled curve. Low impedance and high sensitivity mean it pairs well with virtually any source, from a laptop headphone output to a professional audio interface.

• Frequency Range: 5 Hz – 28 kHz — extends well beyond audible limits for full-spectrum monitoring
• Impedance: 25 Ω — easy to drive, no dedicated amplifier required
• Engineers can count on input power: 150 mW for handling high monitoring levels without strain.

Build, Comfort, and Connectivity — Built for Real Sessions

Long mixing sessions demand a headphone that disappears on the head, and the Hi-X65 weighs just 310 g without its cable. Premium memory foam ear pads and a soft, deep headband distribute pressure evenly, while the metal headband mechanism tilts and swivels to fit a wide range of head shapes. Two detachable cables and a 6.3 mm adapter ship in the box, so the headphone is ready for both desktop and rack-mounted studio gear.

• Weight (without cable): 310 g — light enough for full-day sessions without fatigue
• With its open-back over-ear construction, users experience a wide soundstage and natural imaging, staying comfortable even during long hours.
• Cables Included: 3 m + 1.2 m detachable — flexible setup at the desk or on the move
• Connector: 3.5 mm with 6.3 mm adapter — compatible with pro and consumer sources
• Package Contents: 6.3 mm adapter, manual, cables — ready to use straight from the box

Who the Hi-X65 Is For

This model is built for recording engineers, mixing and mastering professionals, and producers who need a reliable open-back reference tool for long sessions in the control room. It suits creators who already own a neutral monitoring chain and want a headphone that reveals sibilance, masking, and balance issues without flattering the source. Home studio users, podcast editors, and critical listeners who value honesty over warmth will also find the Hi-X65 a strong match, especially given its low impedance and easy drivability from laptops and audio interfaces.

Austrian Audio — Engineered in Vienna

Austrian Audio was founded in Vienna by a team of former AKG engineers carrying decades of professional audio expertise into a new generation of microphones and headphones. The Hi-X65 is designed and built in Austria, and it earned the TEC Award in 2022 in recognition of its engineering and reference-grade performance. The brand's Hi-Xcursion driver technology represents a fresh approach to studio monitoring, combining precision engineering with the ruggedness demanded by daily professional use.
