Yes you can, but depends how long you will be out, and how long you will be calling with, or how long are you going to listen music, for my experience I use just ones at time, listen music the whole day at work but I call a lot too like almost 7 hrs latter I have change it, So yes you can leave the case at home...! anyway each earbud have the same controls, MFB, Volume +-. I hope this can answer your question.
