The M23 PRO is a Bluetooth 6.0 receiver/transmitter designed to provide two-way audio transmission within a hi-fi system. It utilises a dedicated dual-chip architecture – one chip for reception and the other for transmission – to manage incoming and outgoing audio streams simultaneously, whilst its OLED display allows pairing information to be viewed directly.
It features a range of connections, including optical and coaxial inputs and outputs, as well as a USB host port. The device is powered by a 1200mAh battery offering up to 42 hours of transmission time and 38 hours of reception time, allowing for extended use, particularly as the automatic reconnection after pairing makes it easy to resume use on a daily basis.
