EarbudSwitch

A tiny utility that switches audio input/output the moment you plug in USB-C earbuds

Problem

Plugging in USB-C earbuds often doesn't switch audio output, and noise-cancelling headsets still route to speakers during calls, forcing users to dig through system settings every day. Options are scattered and behave differently per device.

Solution

A menu-bar utility that watches audio device plug/unplug events, remembers each headset's preferred input/output combo, and switches with one click or hotkey. Adds per-app overrides (e.g. meeting apps) and simple auto-rules like switch-on-plug.

Users

Remote workers and podcast/editing users with multiple headsets and daily calls on Mac/Windows

MVP

Observe audio device plug/unplug events; remember per-device input/output preferences; simple on/off auto-switch rule; menu-bar and hotkey manual switching; per-app default device rules

Revenue

One-time purchase of $8–15, or free tier limited to two rules with Pro unlocking unlimited rules; affiliate promotion in headset review and podcast communities

Why now

OS vendors keep ignoring these edge device experiences and users swap devices more often; a single-binary system utility fits one developer in 1–2 weeks with clear technical scope
