AirBuddy brings the same AirPods experience you have on iOS to the Mac. With AirBuddy, you can open up your AirPods case next to your Mac and see the status right away, just like it is on your iPhone or iPad. A simple click and you're connected and playing your Mac's audio to AirPods. Oh, it also makes sure the audio input of your Mac is NOT switched to the AirPods automatically when connecting so you can get the best possible quality.
