Hi-X55 Professional Closed-Back Over-Ear Headphones

Austrian Audio Hi-X55

High Excursion Technology

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 the 3-ply membrane really shows results: it is ultra-stiff while still reducing unwanted resonance. 

Maximum Comfort

One key thing that we learned is that headphones need to be as comfortable as they are reliable and excellent sounding. We’ve designed a fresh take on an ultra-adjustable and wide-range head bow for maximum comfort during the longest sessions.
