EarA 0.5.0: Bringing Nothing and CMF Earbud Controls to Linux

Description and use

EarA provides full control of Nothing and CMF earbuds on Linux, matching mobile app functionality.

Problem

Linux users can pair modern earbuds but lack access to battery, ANC, EQ, gestures, and other controls that are usually locked in mobile companion apps.

Outcome

EarA enables full control of Nothing and CMF earbuds on Linux, matching mobile app functionality and improving reliability across audio and Bluetooth setups.

Workflow

• Install EarA via package or source
• Pair earbuds with Linux Bluetooth stack
• Launch EarA GUI or CLI
• Use GUI to view battery, switch ANC, adjust EQ, remap gestures, etc.
• Use CLI for structured status output and remote control

Evidence

Linux can pair with modern earbuds just fine, but pairing is only half the experience.

Source

I built EarA to close that gap for Nothing and CMF earbuds.
