#2 Can I use just one Vista 2 at a time the same way I can with the original Vistas? I see there’s a function that pauses the music if one falls out so I’m not sure if/how that affects using just one at a time
You can use just one bud at a time with Vista 2, but you will want to turn off the auto pause feature in the app. Connect your buds, then under more settings toggle auto pause to off.
