What is Hi-X25BT?
The Hi-X25BT is Austrian Audio's closed-back, over-ear headphone with wireless connectivity. Built on the studio-oriented Hi-X line, it packs Bluetooth, USB-C and analog connections into one unit.
It uses the line's shared 44 mm High Excursion driver. A ring magnet and copper-clad aluminum voice coil drive a light diaphragm, which the maker says gives crisp detail and tight low end.
Bluetooth is version 5.0, and the listed codec is SBC. A microphone is built in for calls and touch controls are provided. It can also connect digitally to a computer over USB-C, or by analog cable.
The body folds, weighs 270 g without cable, and uses memory foam on ear pads and bow. The built-in lithium polymer battery is rated for 30 hours, and the design anticipates checking on the go and commuting.
Three connection modes
It supports Bluetooth 5.0 wireless, digital audio over USB-C and analog through a 3.5 mm jack. It may suit people who want a cable or USB at home and Bluetooth when out.
44 mm High Excursion driver
The in-house unit shared by the Hi-X series. The maker describes a ring magnet producing a strong magnetic field and a light voice coil moving the diaphragm.
Built-in mic and touch control
A mic for phone and conference calls is built in, with touch controls on the ear cup. It may be handy as a headset for online meetings or pre-stream chats.
30-hour run time
The listed run time is 30 hours from a built-in lithium polymer battery, charged over USB-C. That may reduce charging during several days away.
Closed-back, foldable body
The closed-back shell helps block outside noise and the unit folds for carrying. Ear pads and bow use memory foam.
Cables and adapter
The listed spec includes a 1.4 m jack cable, a 1.2 m USB-C cable and a USB-C to USB-A adapter, which helps on computers without USB-C ports.
