If you want one pair of headphones that moves with you from wired studio work to wireless listening, choose Austrian Audio Hi-X25BT; if you need a hands-on FL Studio production setup plus a dedicated pair of monitoring headphones in one box, choose Audiosavings Novation FLkey 49.
• Austrian Audio Hi-X25BT — biggest strength: true hybrid connectivity (3.5 mm jack, USB-C, and Bluetooth 5.0) with 44 mm High Excursion drivers and up to 30 hours of wireless playback.
• Austrian Audio Hi-X25BT — biggest trade-off: it's a headphone only, so it does nothing for beat making, sequencing, or hands-on control in a DAW.
• Audiosavings Novation FLkey 49 — biggest strength: deep native FL Studio integration with 49 velocity-sensitive keys, 16 RGB pads, 9 faders, and 8 pots, bundled with PRO-M50 monitoring headphones.
• Audiosavings Novation FLkey 49 — biggest trade-off: it's a desk-bound, USB-bus-powered studio tool, and its included headphones are wired-only with no Bluetooth.
• Who each pick is for: pick the Hi-X25BT if headphones are the whole job; pick the FLkey 49 bundle if you produce in FL Studio and want control plus monitoring in one purchase.
The Hi-X25BT is a closed-back, over-ear headphone built around Austrian Audio's High Excursion driver design — a 44 mm dynamic driver paired with a ring magnet system and a copper-clad aluminum voice coil. The engineering goal is a light, fast-moving membrane, which the brand ties to precise, clear sound and low total harmonic distortion at low frequencies. On paper that points to a headphone meant for detail work, not just casual listening, and the 18 Hz – 22 kHz frequency range backs up the low-end reach.
What makes it unusual is the connectivity. You get an analogue 3.5 mm jack (with a 1.4 m cable and a 3.5 mm to 6.3 mm adapter in the box), digital audio over USB-C with a 1.2 m cable, and Bluetooth 5.0 with roughly 10 meters of range. It can also charge over USB-C while you keep playing through USB-C or Bluetooth. That's a genuinely practical trio: plug into an interface for tracking, go wireless on a commute, then come back to wired at the desk without swapping gear. The claimed battery life is up to 30 hours wirelessly, and analogue listening never needs power at all.
Who should buy it: anyone who wants one headphone for both studio-adjacent work and daily wireless use, plus people who value build quality — the hinges are all metal, and the earpads use soft slow-retention memory foam, which is the kind of material that stays comfortable over long sessions. At 270 g and 25 ohms, it's light and easy to drive from a phone or laptop. Who should skip it: producers who need keys, pads, and faders. There's no noise cancellation here, and no DAW control — this is a listening tool, not an instrument.
This bundle is really two products in one box. The centerpiece is the Novation FLkey 49, a 49-key MIDI keyboard controller purpose-built for FL Studio. The integration is the headline: direct access to the Sequencer, Channel Rack, Mixer, and transport controls, so you can build patterns, edit automation, browse presets, quantise, toggle the metronome, and undo or redo without reaching for the mouse. That's the difference between sketching an idea and fighting a workflow.
The hardware matches that ambition. You get 49 velocity-sensitive keys, 16 RGB backlit velocity-sensitive pads, 9 faders with 9 fader buttons, 8 customizable pots, pitch and modulation wheels, and a 16 x 2 character screen for feedback. Scale mode, Note Repeat, Fixed Chord, and one-finger chord options are there to help you build melodies and harmonies quickly even if you're not a trained player. It's also NKS-ready for compatible Native Instruments software, and it offers 5-pin MIDI out, a sustain pedal input, USB-B connection, and USB bus power. It runs on Windows 11/10/8.1 and macOS 13 down to 10.15, and the bundle includes a 6-month trial of FL Studio Producer Edition plus software from GForce, Native Instruments, XLN Audio, AAS, Spitfire Audio, and Klevgrand. Physically it's 789 x 258 x 77 mm, so plan real desk space.
The second half is the PRO-M50 studio headphone: closed-back, circumaural, 40 mm neodymium drivers, 32 ohms, 97±3 dB sensitivity, 10 Hz – 25 kHz, 290 g. It includes a detachable 100% OFC coiled cable, gold-plated connectors, both leather and suede ear cushions, and a hard travel case. Who should buy it: FL Studio users who want tactile control and a monitoring headphone in a single purchase, especially beginners who also want the bundled software to get started. Who should skip it: anyone who mainly wants wireless listening — the PRO-M50 is a wired monitoring tool, and the keyboard needs a laptop or PC to do its job.
• Best for wireless freedom → Austrian Audio Hi-X25BT. Bluetooth 5.0 with up to 30 hours of playback and a 10-meter range; the FLkey bundle has no wireless audio at all.
• Best for FL Studio workflow → Audiosavings Novation FLkey 49. Sequencer, Channel Rack, Mixer, and transport control are built in, and the bundle adds a Producer Edition trial.
• Best for commuting and travel listening → Austrian Audio Hi-X25BT. Closed-back, 270 g, memory foam pads, and it charges over USB-C while you listen.
• Best for beat making and hands-on production → Audiosavings Novation FLkey 49. 16 RGB pads, 9 faders, 8 pots, Scale mode, Note Repeat, and chord modes.
• Best for plugging into pro gear → Austrian Audio Hi-X25BT. The 3.5 mm to 6.3 mm adapter and 25-ohm impedance make it easy to drive from mixers, interfaces, and laptops.
• Best as a starter bundle → Audiosavings Novation FLkey 49. Keyboard, monitoring headphones, cushions, case, cables, and software trials arrive together.
• Best for long listening sessions → Austrian Audio Hi-X25BT. Slow-retention memory foam earpads and metal hinges are designed for comfort and durability over time.
• Best for recording vocals or instruments → Audiosavings Novation FLkey 49. The PRO-M50's closed-back design and coiled OFC cable suit monitoring while tracking.
In my opinion, these two don't really compete — they solve different problems, and the right answer depends on whether you're buying a listening tool or a production rig. If I had to pick one for a typical buyer reading this comparison, I'd choose the Austrian Audio Hi-X25BT. It covers more of daily life: wired for detail, USB-C for digital, Bluetooth for everything else, plus metal hinges and memory foam that suggest it'll hold up. I'd only steer you to the Audiosavings Novation FLkey 49 bundle if FL Studio is your main creative home and you want keys, pads, faders, and a monitoring headphone arriving in one purchase. Both are solid at what they're built for — just be honest about which job you actually have.
FAQ
Yes. It supports Bluetooth 5.0 with roughly 10 meters of range and up to 30 hours of playback, and it can also run wired over 3.5 mm jack or USB-C. Analogue listening works without any battery at all.
No. It's a USB bus-powered controller that needs a laptop or PC running macOS or Windows, and it's designed around FL Studio integration. It does offer 5-pin MIDI out and a sustain pedal input for flexible setups.
They serve different roles. The Hi-X25BT uses 44 mm High Excursion drivers, 25 ohms, and 18 Hz – 22 kHz, and adds Bluetooth. The bundle's PRO-M50 is closed-back with 40 mm neodymium drivers, 32 ohms, and 10 Hz – 25 kHz, plus a detachable coiled cable and both leather and suede cushions.
If you're starting in FL Studio and need control plus monitoring, the FLkey 49 bundle gives you the most to begin with. If you mainly want great-sounding headphones for both work and everyday listening, the Hi-X25BT is the more versatile single purchase. Either way, check the current price on Amazon before deciding, since that's the one variable this comparison can't cover.
