Turn off Phone profile for your headphones (but that will also keep you from being able to make calls using the headset). Or just set your phone to Vibrate.
Oh, forgot about these being buds (maybe). If that's the case, yeah, they have a special notification section just for the Buds on the Wearable app.
The best resolution is to install the Samsung "Sound Assistant" app. Then in that app, go to advanced settings and turn on this switch. Sure is weird way to make this work though!![]()
