Austrian Audio has developed the world’s best rated headphone/driver. The path to developing professional headphones was the first time in Austrian Audio, a continuous goal and challenges that appear after another. But we poured all the power and succeed in overcoming them. The new Austrian Audio product is the birth of the Professional Hi-X (High Excursion= High Excursion) headphones. The Hi-X55 is made with a whole new design and each model is guaranteed to be “Made in Austria” quality. No ready-made products are used for drivers or important parts. All are made in Austrian Audio, Austria.
