The Austrian Audio Hi-X25BT is a closed-back hybrid: Bluetooth 5.0 wireless, USB-C digital audio, or analog 3.5 mm wired. The same Hi-X driver family as the wired models keeps monitoring consistent whether you are tracking in the studio, editing on the train, or taking a call between sessions.

Hybrid Connectivity

Switch freely between analog jack, USB-C (including charging while listening over USB-C or Bluetooth), and wireless. Bluetooth runtime is up to 30 hours on the built-in lithium polymer battery. Touch controls and a built-in microphone handle playback and calls without pulling out a phone.

Professional Sound, Everyday Use

Closed-back isolation and foldable construction make the Hi-X25BT a single pair for studio work and travel. When you need zero wireless latency or battery anxiety, plug in the analog cable and listen like a conventional studio headphone.
