Which audio control
do you need?

Sharing a sound, changing an ear’s volume and turning down one app are three different tasks. Choose the tool that matches yours.

By MarSys, the maker of BalanceBar. This comparison explains our app’s scope alongside other tools; it is not an independent review.

For balance and quick mono controls

BalanceBar puts these controls in the menu bar. macOS also includes output balance in Sound settings and mono in Accessibility → Audio. If you only change these settings occasionally, the built-in settings may be enough.

Balance and separate-ear setup

For the same audio on two devices

Apple’s Audio MIDI Setup creates a Multi-Output Device. BalanceBar offers a menu-bar workflow for starting and stopping sharing, supported device volumes and optional keyboard volume control. Both depend on the connected devices’ capabilities.

Two-device setup and limitations

For a different volume in each ear

BalanceBar’s Separate ears mode sets left and right channel volumes independently where macOS exposes writable controls. It has been verified with AirPods Pro 3. This is different from assigning a volume to an entire application.

For individual app volumes or audio effects

BalanceBar does not adjust Safari separately from Spotify, add an equalizer, record audio or route a different app to each listener. SoundSource by Rogue Amoeba offers per-app volume and audio effects. Those needs call for a different kind of tool.
