A:AnswerYou don't need a app to use them, you just need your regular Bluetooth. But there is an app so you can customize the touch sensors on the headphones if you would like.
A:AnswerMy friend recommended these after he uses them at the gym with his iPhone. I have an iPhone. We both effortlessly connected them and we didn’t spend a couple hundred bucks.
A:AnswerThe earbuds charge wirelessly in the case.
However, the case needs to use a charging cord to charge.
The earbuds lasted me over 2 hours with each use because that’s all I needed. The case kept my earbuds charged for over 14 uses. 14 x 2 =28 hours between charging the case.
