A:AnswerLike most headphones of this type the battery is charging only until full anytime it is in the case. The case only loses battery when it is charging the headphones. The headphones are only “on” when they are in your ears.
A:AnswerI tried and would not recommend sleeping with these in if you sleep on your side and have the bud on the side that is down. My ear and ear canal size is medium and they stick out a little and will irritate some and will click if not careful.
A:AnswerI highly doubt that you can try them on in the store, but I am not certain. I AM certain that with the included ear tips, you WILL find a size that fits your ears! This is the ONLY pair of ear buds that have EVER fit in my ear correctly. The little “stem” that is attached to the buds makes all the difference. Although you can’t really feel it when they are in your ears, they really do “lock” into place.
