The August MR230 is a Bluetooth audio receiver designed to add wireless audio streaming capability to any existing sound installation — including hi-fi systems, iPhone docks, radio/CD players, and similar equipment — without replacing the audio system itself. It receives audio from any Bluetooth-enabled source, including smartphones, tablets, laptops, and PCs with a Bluetooth USB dongle, and outputs it via RCA or 3.5mm jack.

A built-in rechargeable 3.7V/200mAh lithium-polymer battery provides up to 10 hours of working time on approximately 1.5 hours of charge, meaning the MR230 does not need to be permanently connected to a power source. A multi-function button on top of the device handles muting, Bluetooth reset, and pairing with a new device. Bluetooth v4.2 with apt-X LL transmits in the 2.402–2.480GHz band for a high-quality wireless connection.
