A:AnswerI had that I had that same problem what I did is I pair it one at a time and I think once you care in both single one at a time then if you care the right one if you take them both out they were both automatically pair got to keep playing with it
A:AnswerThey have 4 different ear adapters that makes the fit pretty snug from my experience. I have been anywhere from 10-20 yards away and still stay connected in an open spot.
A:AnswerI have a Samsung note 9 and they connect automatically once you pair them the first time. Spotify takes a minute to start playing on it own but it's faster if you just go straight to the app.
A:AnswerYep! I typically leave the right one in the case with the case closed and have the left one in listening to music while my headset is on my right ear. Then if I get a call I just remove the left one which automatically pauses the music.
