A:AnswerAssuming you meant iPhone SE, yes. I have them paired to an iPhone 6s, which is the same innards as the original SE. I’ve also paired them to my iPad Pro 2nd gen. So I’m sure anything newer (SE 2, SE 3) will pair no problem.
A:AnswerI would try to do this...just set to "forget" on your phone if you paired it before and press and hold both earbuds for a long time and when you release both will be flashing...then you put both of them back in the charger case and take it out pair it again with your phone or device....it should work for both sides...
A:AnswerIs the case completely depleted of its charge? Check that the voltage output of the wall adapter you are using is 5V with at least .65A 2.4Wh. Anything less will not be strong enough or if your adapter is 9V you may have fried it.
