A:AnswerYou’ll need an adapter which is around $25-$30 dollars. I think it’s best if you look for newer ones which cost $30 instead of $20 I think. But yes you will need an adapter or “dangle” as I’ve seen it called, if you want to buy these exact earphones
A:AnswerNope . There is an alternate headset which has that piece st the bottom which you out in where the charger would go as supposed to the audio circle
A:AnswerOops. I misstook the product you were asking about. They used to come with the plastic case. The last few pairs I purchased did not come with it. It was just wrapped on a little cardboard thing. Very unApple. Fortunately, I saved some plastic cases from earpods that were damaged.
A:AnswerMy new Apple EarPods stay in my ears very well -- they are shaped correctly and labeled for which ear each should go into for that purpose. Also, I found the volume control will easily make the sound as loud or soft as you need. The microphone is spaced just the right place, too.
