EarA is an unofficial Linux companion application for Nothing and CMF earbuds. It provides a GTK4 interface for managing earbud settings without relying on the manufacturer’s mobile application.
The application communicates with compatible earbuds over Bluetooth using BlueZ and the devices’ RFCOMM control protocol. It integrates with PipeWire and PulseAudio for audio routing and offers a command-line interface for controlling supported functions.
Nothing Ear (a) has been tested extensively. CMF Buds 2 has verified support for battery reporting, listening modes, equaliser controls and Bluetooth audio. Other Nothing and CMF models have device profiles, although individual features may require further hardware testing.
This is free and open source software.
