Austrian Audio HXCA1m4 USB-C to 3.5mm Cable 1.4m for Hi-X25BT

Austrian Audio HXCA1m4 Cable: Wired Analog Listening for the Hi-X25BT

The Austrian Audio HXCA1m4 is a genuine 4.6 ft (1.4 m) detachable cable that gives the wireless Hi-X25BT a wired analog connection. The Hi-X25BT is a Bluetooth headphone, but it also accepts a passive cable so it can be used with no battery and no latency. This cable carries a USB-C plug at the earcup and a standard 3.5 mm jack at the source, converting the headphone into a plain wired monitor. It is the ideal way to keep listening when the battery runs down or when a direct analog link is needed. For any Hi-X25BT owner, it restores a core part of the headphone versatility.

Keep Listening When the Battery Runs Flat

The biggest limitation of any wireless headphone is that it eventually needs charging, and the Hi-X25BT solves this with a wired fallback. Plugging in the HXCA1m4 lets the headphone play in passive analog mode with no power at all, so a dead battery never means silence. This makes the Hi-X25BT dependable for long days, flights, and sessions where charging is not an option. The cable turns a wireless convenience into an any-time tool.

USB-C Earcup End and 3.5 mm Source Jack

The earcup end uses a USB-C plug shaped to fit the Hi-X25BT connector, while the other end terminates in a familiar 3.5 mm TRS jack. Here the USB-C carries analog audio rather than data, which is why the cable connects straight to a headphone output or interface. Because the fit is exact, the connection is solid and passes the full signal without dropouts. It is a purpose-made lead rather than a generic USB cable, which matters for reliable analog playback.

Latency-Free Monitoring for Tracking and Video

Bluetooth introduces a small delay that makes wireless headphones unsuitable for recording or editing to picture. Connecting the HXCA1m4 removes that delay entirely, giving the tight, real-time monitoring that tracking and video work demand. Editors gain perfect lip-sync, and musicians can play in time with a backing track without hearing an echo. For serious work, this wired mode is where the Hi-X25BT does its most precise listening.
