Detailed Audio Reproduction

The Austrian Audio Hi-X55 closed-back headphones are the skilled surgeon of the Hi-X line, designed to reveal every detail in your recordings. With their mid-forward, analytical sound signature, the Hi-X55 provides an honest and accurate sonic image—perfect for mixing, monitoring, and refining your productions.

At the core of the Hi-X55 are Austrian Audio’s handmade 44mm High Excursion (Hi-X) drivers, which use a ring magnet system and copper-clad aluminium voice coil to reduce membrane weight and improve airflow. The result is faster impulse response, reduced resonance, and crystal-clear audio across the frequency spectrum.

Foldable Design

Built for long sessions, the Hi-X55 features a pressure-reducing headbow and slow-retention memory foam earpads that deliver fatigue-free comfort, even during multi-hour mixing and critical listening. With all-metal hinges, a foldable design, and fully replaceable components, the Hi-X55 is built to deliver reliable performance for years to come.
