Hi, I’m Marko, the maker of BalanceBar at MarSys. I wanted quick control over audio without repeatedly digging through settings. It started with mono and balance, then grew to include separate ear volumes and sharing. AirPods Pro 3 and MacBook speakers work together in our test; two AirPods pairs still need testing. Device and channel volume controls depend on what macOS exposes. Balance and separate-ear controls are disabled while sharing. It’s free and ad-free inside the app, with optional donations on the website. The current DMG isn’t Apple-notarized yet; Apple signing is the next distribution step. You can explore the interactive web preview before downloading. Which devices do you use, and what would you like to control more easily?
