This app is supposed to let you update your headphones to get rid of some of the connection issues that have been plaguing them since their release, especially with the low latency proprietary connection. Especially useful for people without a Windows computer because aiaiai have not managed to support Mac with an updater app so far.
Unfortunately this app does not find properly connected headphones. They show up in the Bluetooth menu, play music, can control playback. But this app pretends like they are not connected.
This app has one purpose and does not fulfill that purpose, should therefore be removed from the App Store.
