Out Loud is a macOS menu bar utility. Press one shortcut and hear a short chime on the headphones you chose — or get a clear reason why your Mac is about to send audio to the speakers instead.
Most audio testers play a sound through whatever the system happens to be using, which is the one thing you cannot trust. If the route already slipped to your built-in speakers, a test tone simply plays out loud. Out Loud binds playback to the specific device it verified and refuses to fall back to anything else.
Press ⌘⇧H anywhere, or choose Test Now from the menu bar. Two other shortcut presets are available if that one is taken.
A matching device name proves nothing. The app checks the Bluetooth address against the devices your Mac has already paired, then rechecks before and during playback.
Pick the outputs allowed to sound the chime. Headphones are remembered by hardware address, so renaming them — even to a single emoji — never loses the selection.
The app never switches your output device, never connects or reconnects anything, and never changes any volume. Change your output mid-check and playback stops.
Menu bar only — no Dock icon and no window sitting open. Optional Launch at Login, and a read-only diagnostics report when you want the full picture.
No account, no network, no analytics, no microphone. The app contains no networking code at all. Read the privacy policy.
The whole app is a menu bar item, a settings window, and a notice that appears when something is wrong.
Out Loud confirms the audio reached the right device; it cannot know whether it reached your ears. A check that passes means the route is correct — headphones that are muted or turned down still need your ears. There is no microphone use of any kind.
To read the list of devices your Mac has already paired, which is the only way to prove a Bluetooth output really is your headphones rather than something that shares their name. The app never scans for nearby devices, and never pairs or connects anything.
No, deliberately. It reports what your Mac is doing and leaves your route and volumes alone. There is a Sound Settings shortcut in the menu for switching outputs yourself.
That is usually the app working. Silence means your current output is not one of your allowed devices, so the chime was withheld rather than played out loud. A notice appears with the reason. More in support.
