Overview
The Austrian Audio Hi-X25BT is a closed back, over ear headphone that connects three ways: analogue via 3.5 mm jack, digital audio via USB-C, or wireless via Bluetooth 5.0. It uses the same 44 mm High Excursion driver technology as the wider Hi-X series for clear, accurate sound.
The built in battery gives up to 30 hours of wireless use, it can charge over USB-C while playing, and analogue listening works even when the battery is flat. A built in microphone handles calls. It suits engineers, musicians and AV techs who want one pair for the studio, the desk and the commute.
