Austrian Audio Hi X65 Review | 93 Data compared

The Austrian Audio Hi-X65 is an open-back, over-ear studio headphone priced at €349, praised by the reviewer as an exceptional, highly analytical tool that punches well above its price class. Built with high-quality metal and plastic components, it features a foldable design for compact storage and a well-ventilated, comfortable fit that completely prevents the uncomfortable pressure buildup common in closed-back variants. In terms of performance, its core strengths lie in its highly linear, distortion-free bass response, incredible detail retrieval, and exceptional clarity across the upper mid-range and treble. Instrument separation and depth are outstanding, and the low impedance (25 Ohms) makes it relatively easy to drive, though pairing it with an external amplifier like the iFi ZEN DAC adds an impactful bass boost via software that perfectly transforms this precise studio workhorse into an engaging hi-fi headphone.

The Austrian Audio Hi-X65 is an open-back, over-ear headphone praised for its exceptional neutral sound signature, high-quality build, and excellent comfort at a competitive price point of €349. Built by former AKG engineers, this model features a 25 Ω "Hi-X" driver that makes it highly sensitive and easily driven by mobile devices, though it scales up nicely with dedicated amplifiers. The reviewer highlights its precise, clean, and crystal-clear presentation across the frequency spectrum, noting that it acts like a high-quality studio monitor without any artificial warmth or frequency coloration. Its open design allows for an organic, lifelike bass response and a highly spacious, three-dimensional soundstage with stellar instrument separation, making it an ultimate tool for analytical listening, mixing, mastering, or gaming. The review explicitly outlines several pros, including its perfectly balanced, neutral tuning, robust metal-and-plastic construction, lightweight design (310g), and outstanding long-term wearing comfort due to memory foam ear pads. Additionally, it improves upon its predecessor by including both a 3m and a 1.2m detachable cable in the box. On the cons side, the review explicitly states that balanced operation...

The Austrian Audio Hi-X65 is an open-back, over-ear headphone designed for studio professionals and audiophiles that delivers exceptional clarity and a wide soundstage. It features custom 44 mm drivers with a 5 Hz to 28 kHz frequency range, a low impedance of 25 Ohms, and a highly functional design including a foldable metal frame, replaceable memory foam pads, and a secure cable-lock mechanism. Pros highlighted in the review include its crystal-clear and detailed sound reproduction, excellent vocal intelligibility, punchy sub-bass reserves when adjusted via equalizer, and high overall wearing comfort over long sessions. Additionally, it offers a practical package with both 1.2-metre and 3-metre detachable cables, making it versatile for both mobile Hi-Fi listening and desktop studio environments. However, the headphones also come with specific drawbacks depending on the use case. Cons include a relatively low clamping force, which keeps the fit comfortable but causes the headphones to easily slip out of place during quick head movements. Sonically, the native bass response feels somewhat restrained due to the open-back design, and the stereo image is so wide that the acoustic...

The Austrian Audio Hi-X65 is an open-back, over-ear studio headphone specifically engineered for demanding mixing and mastering tasks, though it also appeals to critical audiophiles. Priced at 349 Euros, the headphones weigh 310 grams and feature a durable build with a metal headband and ear cup hinges, memory-foam synthetic leather ear pads, and two detachable cables (1.2m and 3m). Driven by custom 44 mm "High Excursion" drivers, the Hi-X65 stands out for its outstanding tonal neutrality that closely matches high-end studio monitors, avoiding any artificial emphasis in the mids or lower treble. Furthermore, its exceptionally low 25-ohm impedance makes it remarkably easy to drive even when connected directly to mobile devices or weaker amplifiers. The review highlights several core strengths, including an incredibly balanced frequency response, exceptional micro-dynamics, meticulous detail reproduction, and razor-sharp spatial imaging that clearly pinpoints the location of individual elements in a mix. However, these studio-centric characteristics introduce certain drawbacks: the highly analytical, unforgiving sound signature exposes every flaw in low-quality source material, which casual listeners might find unappealing or lacking warmth. Additionally, its narrow soundstage width...

The Austrian Audio Hi-X65 is an open-back, over-ear studio headphone designed and fully manufactured in Vienna, Austria, offering exceptional technical performance at a highly competitive price point of €349. Built with durable materials and a highly flexible, folding design for easy transport, it features a low impedance of 25 Ohms, making it versatile enough to be easily driven by mobile devices as well as high-end studio headphone amplifiers. The review highlights its outstanding comfort, notable for a forward-leaning headband that distributes the 310-gram weight effectively for all-day mixing and editing sessions, though users with particularly small heads should verify the security of the fit. In terms of sonic performance, the review praises the headphones for their clinical accuracy, delivering a highly neutral sound stage with excellent dynamic responsiveness, pristine high-end detail, and remarkable depth for precise panning. The specific pros include its top-tier resolution across the entire frequency range, highly neutral tuning, superb transient response, comfortable fit, and the high value of being produced in the EU. On the flip side, the cons are non-existent according to the reviewer’s final...

The Austrian Audio Hi-X65 is an open-back, over-ear studio monitor headphone designed in Austria by former AKG engineers, carrying forward the acoustic heritage of that iconic brand. Priced around €350, it features proprietary 44mm "High Excursion" drivers that boast an expansive frequency range of 5 Hz to 28,000 Hz. Built with a highly portable, foldable design, it departs from AKG's traditional bulky round earcups in favour of a more compact, racetrack-shaped shell that still manages to offer generous space for the ears. Technically optimized for both studio and mobile use, the headphones feature a low impedance of 25 Ohms and a high efficiency rating of 110 dB, allowing them to be driven easily by battery-powered portable devices without sacrifice. Sonically, the reviewer awards the headphones a perfect 5.0 out of 5 stars, placing them in the "top tier" (Spitzenklasse) for their exceptionally linear, transparent, and revealing reference-level sound. The distinct pros highlighted in the review include an un-emphasised, incredibly deep bass response with superb nuance differentiation, excellent clarity and detail across the midrange and high frequencies, a robust and premium...

The Austrian Audio Hi-X65 is an open-back, over-ear dynamic headphone designed by former AKG engineers in Vienna for studio professionals and experienced audiophiles. Priced at 349 Euro, it features 44mm High Excursion drivers and 1-Tesla magnets that deliver exceptional transient speed, immense clarity, and an incredibly high-resolution "detail-monster" sound signature comparable to much more expensive reference models. Visually appealing and exceptionally comfortable right out of the box, the headphones utilize plush memory-foam ear pads and an optimal clamping force that safely secures the lightweight 310g frame for long listening sessions without causing pressure points. Additionally, the package includes both 3-metre and 1.5-metre detachable, non-microphonic cables that resist tangling. However, the reviewer highlights critical long-term drawbacks regarding the physical durability and the intense sound pressure. The high-excursion technology and strong magnets produce a highly forceful sound delivery that can easily cause ear fatigue during casual listening, making regular breaks necessary. The most severe flaw lies in its structural engineering; after just two months of use, the critical connection joint between the headband and the ear cup snapped completely in half. Although...
