Austrian Audio Hi-X55 review

The Hi-X55 comes from Austrian Audio, and the company pitches it at critical listening and mixing decisions rather than casual use. It calls the Hi-X55 a mid-forward, closed-back headphone that uncovers every detail in a mix, driven by handmade 44 mm High Excursion drivers with a ring magnet system and a copper-clad aluminum voice coil. For long sessions it has a pressure-reducing head bow and memory foam pads. The build is foldable, with all-metal hinges and bow, a detachable 3 m cable and an included 6.3 mm adapter, and Austrian Audio says it is 100% serviceable and made in Austria. At 25 ohms and 118 dBspl/V it should run from most interfaces. The listed range is 5 Hz to 28 kHz and the weight is 305 g without the cable. At $349 it costs more than every other closed-back pick here, and its mid-forward voicing is a matter of taste. We compared documented features and published prices; we did not test it.
