The Hybrid: Wireless. Digital. Analogue. Professional sound, no matter where or how.

Our Hi-X25BT closed-back Bluetooth® headphones are a pro-level hybrid. You decide how you want to connect — via analogue (3.5 mm jack) or digital (USB-C®), wired or wirelessly. Enjoy the precision and clarity of award-winning High Excursion technology wherever you are. Hybrid convenience at the professional level designed and engineered in Austria.

Imagine recording a song in a professional studio, listening to your favourite music on the way home in the underground, calling your band mates while you’re at it, and then finishing your song mix at home without ever changing headphones. No matter where you are or how you like to work, your Hi-X25BT headphones will be there for you.

Hi-X25BT headphones set the standard in connectivity. They offer analogue audio via jack, digital audio via USB-C®, and absolute freedom wirelessly via Bluetooth. To keep you in the flow, they can be charged with a USB-C connection while playing music via Bluetooth. Thanks to the built-in high-efficiency battery, you can enjoy up to 30 hours of play wirelessly via Bluetooth®, and of course, analogue listening is always possible.

High Excursion Technology

Hi-Xcursion (High Excursion) technology is the key to the astonishing sound of our Hi-X25BT headphones.

All Austrian Audio Hi-X headphones feature a 44 mm driver and a ring magnet system. This design allows for improved airflow and includes the strongest magnetic field in its class.
The ring magnet, combined with a copper-clad aluminum voice coil, reduces the weight of the membrane and the voice coil connected to it, allowing the membrane to move or change direction faster, providing a more responsive impulse reaction.

Our science, measurements, and listening tests have shown that 44mm is the optimum size for this design. It ensures professional performance in the Hi-X, moves a lot of air, and eliminates ‘wobbling’ of the diaphragm. This is akin to damping of the driver mass, which is where our membrane really shows results: it is ultra-stiff while still reducing unwanted resonance.
