PolySound - Play Mac audio on multiple speakers and headphones at once

by•
PolySound brings multi-device audio to your Mac's menu bar. Play system audio through multiple connected speakers, headphones, AirPods, HDMI outputs, or USB DACs at once. Adjust each device's volume separately, and let PolySound rebuild your output setup when devices connect or disconnect. Free, entirely offline, and without tracking. Requires macOS 14.6 or later.

Hi Product Hunt! I'm Manan, the maker of PolySound. PolySound makes it easier to play your Mac's audio through several connected devices at once. Choose your outputs from the menu bar, adjust their volumes individually, and the app handles the multi-output setup. It's free and runs entirely on your Mac, with no tracking or analytics. It also rebuilds the output when devices connect or disconnect. I'd love feedback on the device combinations you use and what would make shared listening easier. If something doesn't work, please share your macOS version and device models so I can investigate. Thanks for trying it!
