If you want reference-grade, wired, open-back accuracy for critical mixing and mastering, choose Austrian Audio Hi-X65; if you need a flexible wired-and-wireless over-ear with big bass and Hi-Res Bluetooth codecs for everyday listening and jogging, choose OneOdio Studio Max 1. That's the whole decision in one line. Everything below is me walking through why, spec by spec.
• Austrian Audio Hi-X65 — biggest strength: a purpose-built open-back, over-ear reference design with a 44 mm driver, ring-magnet system and copper-clad aluminium voice coil, tuned for close, precise listening during mixing and mastering.
• Austrian Audio Hi-X65 — biggest trade-off: it's wired only, it's open-back (so it leaks sound and lets the room in), and it has no Bluetooth or noise cancelling at all.
• OneOdio Studio Max 1 — biggest strength: genuine flexibility — wired and Bluetooth, 50 mm dynamic drivers, Hi-Res Audio and LDAC certification plus LC3 decoding, and a bundled USB-C to 3.5 mm DAC adapter rated for 24-bit/96 kHz.
• OneOdio Studio Max 1 — biggest trade-off: the data sheet is thin on the studio specifics — no impedance, no frequency range, no weight — so it's harder to judge as a reference tool than the Austrian Audio.
• Who each is for: Hi-X65 for the producer or engineer who needs a trustworthy wired reference; Studio Max 1 for the listener who wants one headphone for the desk, the commute and a jog.
This is a specialist tool. Austrian Audio describes the Hi-X65 as built specifically for mixing and mastering, and the spec sheet backs that up: a 44 mm dynamic driver, a ring-magnet system, a copper-clad aluminium voice coil, 25 ohm impedance and a stated frequency range of 5 Hz to 28 kHz. The engineering story here is about impulse response — a lighter membrane and voice coil move faster, which is why the brand talks about responsiveness rather than thump. Open-back, over-ear, aluminium enclosure, 310 g, 3.5 mm jack with a 1/4" adapter in the box.
The practical consequences matter more than the marketing. Open-back means the cups don't seal, so you get a wide, airy presentation and less of the trapped, boxy feel that closed cups can add — which is exactly what you want when you're judging reverb tails, stereo placement or whether a vocal sits right. It also means sound escapes and outside noise walks straight in. If you're tracking a live mic in the same room, that bleed is a real problem. If you're mixing at a desk, it's a non-issue.
The build is clearly aimed at people who treat gear roughly: an all-metal hinge and bow, a folding design for storage and travel, a 3 m cable plus a 1.2 m cable, and a carry case. Two cables is a smarter detail than it sounds — the long one stays at the desk, the short one goes in the bag. A 2-year warranty rounds it out.
Buy it if you're doing critical listening work — mixing, mastering, editing, referencing — and you want a wired, open, honest pair that folds flat and survives being thrown in a rucksack.
Skip it if you want wireless, want noise cancelling, want to use headphones on a run, or want something that isolates you on a train. The Hi-X65 does none of those things, and it isn't trying to.
The Studio Max 1 is the opposite personality: a generalist that tries to cover every base. Over-ear, black, dynamic drivers — 50 mm this time — with the brand claiming oxygen-free copper-clad coils for deep bass and clean highs. Crucially, it's both wired and wireless: Bluetooth on one side, a 3.5 mm jack on the other, so it works with a phone, a laptop and a controller without a dongle.
The wireless spec is the interesting part. It's certified for Hi-Res Audio and LDAC, with LC3 decoding support for lossless transmission — LDAC being the higher-bitrate Bluetooth codec Android users can actually enable, LC3 being the newer low-complexity standard built for efficiency. In plain terms, this is a headphone designed so that going wireless doesn't automatically mean going mushy. And the bundled USB-C to 3.5 mm adapter contains a DAC chip supporting 24-bit/96 kHz sampling, which turns a USB-C-only phone or laptop into a proper analogue source.
Where the data sheet goes quiet is the studio side. There's no impedance figure, no frequency range, no weight, no cable lengths. For a product named "Studio," that's a gap — I can't tell you how hard it is to drive or how flat it measures. What I can tell you is what the design implies: closed over-ear cups, 50 mm drivers described with a bass-forward tuning, and dual connectivity. That's a listening headphone that can moonlight in a home setup, not a calibrated reference monitor.
Buy it if you want one pair for everything — music on the move, calls, gaming, casual listening at a desk — and you'd rather have wireless convenience plus a wired fallback than a single-purpose studio tool. The DAC adapter is a genuinely useful extra if your phone dropped its headphone jack.
Skip it if your job depends on a known, repeatable reference sound. With no published impedance or frequency response, you'd be trusting a description rather than a specification.
• Best for mixing and mastering → Austrian Audio Hi-X65. It's the one explicitly designed for it, with the driver, magnet and impedance data to match.
• Best for wireless freedom → OneOdio Studio Max 1. Bluetooth, LDAC, LC3 and Hi-Res Audio certification; the Austrian Audio has no wireless mode at all.
• Best for jogging → OneOdio Studio Max 1. If you're hunting for the best bluetooth headset for jogging and you prefer an over-ear fit, this is the only one of the two that can leave the desk. Wired-only open-backs and running don't mix — no cable snagging, no sweat-soaked pads, no ambient bleed.
• Best for bass-forward listening → OneOdio Studio Max 1. The 50 mm drivers and the brand's own emphasis on deep bass point that way; the Hi-X65 is tuned for precision, not punch.
• Best for durability and travel → Austrian Audio Hi-X65. Aluminium enclosure, all-metal hinge and bow, folding design, carry case and two cable lengths — that's a hard-wearing travel package.
• Best for a known, published spec → Austrian Audio Hi-X65. 44 mm driver, 25 ohm, 5 Hz–28 kHz, 310 g. Everything you need to reason about amplification is on the sheet.
• Best for one headphone doing several jobs → OneOdio Studio Max 1. Wired and wireless in the same pair, plus the USB-C DAC adapter for jackless devices.
If you're asking me to pick one for jogging, I'd take the OneOdio Studio Max 1 — it's the only one of the two that goes wireless, the LDAC and LC3 support means it isn't a compromise on the move, and the 50 mm bass-forward tuning suits the kind of music most people actually run to. It's the more versatile buy, and the bundled DAC adapter adds real value for anyone whose phone lost its headphone jack.
But I'd be doing you a disservice if I pretended that made it the better headphone. If your priority is accuracy — mixing, mastering, referencing, anything where you need to trust what you're hearing — the Austrian Audio Hi-X65 is the one I'd put my name behind. It's built for that job, the specs are published, and the metal build and folding design mean it'll survive the years you'll keep it.
Two different products, two different jobs. Buy for the job you actually have. And before you commit, check the current price on Amazon — the numbers move, and this page doesn't quote them.
FAQ
No, and it's not designed to be. It's wired-only with a 3 m or 1.2 m cable, open-back, and has no Bluetooth or noise cancelling. For running, you want a wireless pair — the Studio Max 1 is the fit here, and a set of wireless earbuds for jogging is an even lighter option if you don't want over-ear cups bouncing.
Based on the specs, that's the reasonable expectation. OneOdio describes 50 mm drivers and oxygen-free copper-clad coils tuned for deep bass, while Austrian Audio tunes the Hi-X65 for high-precision, spacious reference sound. If you want the best extra bass open ear headphones for jogging experience, the OneOdio's tuning is aimed at you — the Hi-X65 is aimed at accuracy instead.
The Hi-X65, in my opinion. It's explicitly built for mixing and mastering, and its published specs — 44 mm driver, ring magnet, 25 ohm impedance, 5 Hz–28 kHz — let you plan around it. The Studio Max 1 is called "Studio" but its sheet omits impedance and frequency range, so it's harder to treat as a reference.
Yes. It has a 3.5 mm jack and Bluetooth, so it works with wired sources and wireless ones, and the included USB-C to 3.5 mm adapter carries a DAC chip supporting 24-bit/96 kHz for devices without a headphone socket. The Hi-X65 is wired only.
