How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a single pair of headphones that moves with you from a wired studio session to a wireless commute, choose Austrian Audio Hi-X25BT; if you need a complete recording front end with a USB interface plus a monitoring headphone in one box, choose M-Audio M-Track Duo. These two products are not really rivals in the same category — one is a hybrid pro headphone, the other is an interface-and-headphone bundle — so the right call depends entirely on whether you're trying to hear audio or capture it.
• Austrian Audio Hi-X25BT biggest strength: genuine hybrid connectivity — analogue 3.5 mm jack, digital USB-C, and Bluetooth 5.0 wireless, all in one closed-back over-ear headphone rated for up to 30 hours of wireless playback.
• Austrian Audio Hi-X25BT biggest trade-off: it has no noise cancellation and no built-in microphone array for calls beyond its media controls, so it's a listening tool, not a noise-cancelling travel gadget.
• M-Audio M-Track Duo biggest strength: it's a full starting studio — dual combo XLR/line/instrument inputs with phantom power, 48 kHz resolution, zero-latency direct monitoring, plus a pair of closed-back studio headphones in the box.
• M-Audio M-Track Duo biggest trade-off: it's tethered to a Mac or PC by USB and capped at 48 kHz, so it's a desktop recording solution rather than something you'd wear out of the house.
• Who each is for: pick the Hi-X25BT if you want one headphone for studio and street; pick the M-Track Duo if you own no interface yet and need to record vocals, guitar or a mic today.
The Hi-X25BT is a closed-back over-ear headphone built around Austrian Audio's High Excursion driver technology: a 44 mm dynamic driver with a ring magnet system and a copper-clad aluminium voice coil, which the design brief says reduces moving mass so the membrane can change direction faster. On paper that translates to the qualities studio users care about — an 18 Hz to 22 kHz frequency range, 25 ohm impedance, 110 dB sensitivity, and a stated focus on low total harmonic distortion at low frequencies. In my opinion that low-impedance, high-sensitivity combination is what makes it so easy to drive from a phone, a laptop or a small interface without a dedicated amp.
The real hook here is connectivity. You get a 1.4 m 3.5 mm jack cable, a 1.2 m USB-C cable, a 3.5 mm to 6.3 mm adapter, and Bluetooth 5.0 with roughly 10 metres of range. That means the same headphone can be plugged into a keyboard or interface, run digitally over USB-C, or go wireless on the train. The battery is rated at up to 30 hours wirelessly, and you can charge over USB-C while still listening via USB-C or Bluetooth. Build-wise it's metal-enclosed with all-metal hinges and slow-retention memory foam earpads, at 270 g.
Buy it if: you want one headphone that genuinely does tracking, casual listening and commuting without swapping gear, and you value a metal build and replaceable-feeling comfort. Skip it if: you need active noise cancellation for flights, or you need an interface and microphone to actually record — this headphone captures nothing.
The M-Track Duo is a different animal entirely. It's a USB audio interface for Mac and PC that records at 48 kHz resolution, with two combo XLR/line/instrument inputs, phantom power for condenser microphones, and Crystal Preamps that M-Audio describes as transparent. There's a switch to toggle between line level and instrument level, which is what you want for a digital piano, drum machine, DI bass or guitar. Monitoring runs through a 1/4" headphone output plus stereo 1/4" outputs, and a USB/Direct switch gives you zero-latency direct monitoring while you track. It's bus-powered over USB, so no separate power supply.
The bundle part matters: this package also includes the HDH40 over-ear studio headphones. Those use a 40 mm neodymium dynamic magnet driver, a 180-degree rotatable frame, stainless steel telescopic arms with a scale, leather cushioning and a flexible headband. Impedance is 32 ohm with 95 dB sensitivity, and the fixed cable is 2.7 m long — long enough to reach across a desk, with a 1/4-inch adapter to plug into mixers, interfaces and digital pianos. The included software suite is MPC Beats.
Buy it if: you're starting from zero and need to plug a microphone and an instrument into your computer the same day, with a usable headphone for monitoring included. Skip it if: you already own an interface, or you need high-resolution recording above 48 kHz, or you want wireless anything — there's no Bluetooth here.
• Best for wireless freedom → Austrian Audio Hi-X25BT. Bluetooth 5.0 with up to 30 hours of playback and a 10 m range; the M-Track Duo has no wireless at all.
• Best for recording a microphone → M-Audio M-Track Duo. Two combo XLR inputs with phantom power and Crystal Preamps; the Hi-X25BT cannot record anything.
• Best for plugging into a guitar, bass or keyboard → M-Audio M-Track Duo. Dedicated line/instrument switching and DI-friendly inputs; the Hi-X25BT is a listening device.
• Best for commuting and travel → Austrian Audio Hi-X25BT. Closed-back, metal-hinged, memory-foam padded and 270 g, with analogue, USB-C and Bluetooth options.
• Best for zero-latency monitoring while tracking → M-Audio M-Track Duo. The USB/Direct switch removes monitoring delay; the Hi-X25BT has no such function.
• Best for hearing detail at low volume → Austrian Audio Hi-X25BT. 25 ohm impedance, 110 dB sensitivity and an 18 Hz–22 kHz range make it easy to drive from almost anything.
• Best all-in-one starter kit → M-Audio M-Track Duo. Interface, monitoring headphone, cables and software in one purchase.
• Best for one headphone that does everything → Austrian Audio Hi-X25BT. Wired analogue, wired digital and wireless in a single pair.
If I had to pick one, I'd buy the Austrian Audio Hi-X25BT. It's the more flexible object day to day: the same headphone works at a desk over 3.5 mm or USB-C, on a couch over Bluetooth, and it's built with metal hinges and memory foam that suggest it'll survive years of that routine. The M-Track Duo is the smarter buy only in one specific situation — you have no way to record yet and you need inputs, phantom power and a monitoring headphone in a single order. If that's you, get the M-Track Duo; if you already own any interface, the Hi-X25BT is the better spend.
Both. It supports Bluetooth 5.0 wireless plus analogue audio over a 1.4 m 3.5 mm jack cable and digital audio over a 1.2 m USB-C cable, and it can charge via USB-C while playing.
Yes. Its two combo inputs supply phantom power, so condenser mics work, and the Crystal Preamps handle both dynamic and condenser models. It records at 48 kHz over USB.
No. The Hi-X25BT is a headphone for listening; the M-Track Duo is a recording interface that happens to include a pair of studio headphones. If you need to capture audio, only the M-Track Duo does that.
Decide by the job, not the category. Recording vocals, guitar or a mic → M-Track Duo. Listening across studio, phone and commute from one pair → Hi-X25BT. Then check the current price on Amazon before committing.
