A:AnswerTechnically with the iphone...no because of compatibility of software. with the A21, yes but it depends on how you are using the phone. These phones are really meant for light usage (like checking email, text and phone calls...maybe the occasional picture). If the previous mentioned is all you do with it, then you shouldn't have issues with the buds. The only thing I can think of that would cause issues with the app is if you ran out of space for the system apps to run everything and if you are trying to do to much at one time. Hope this helps.
A:AnswerApple's description includes the wording, "High-quality call performance" so it seems clear that they would work in your situation as long as your compatible Apple or Android cellphone was within Bluetooth distance. Of course, you could confirm this at any Apple Store before buying.
A:AnswerThis fits a standard USB-C charger. Comes with the USB-C cord. You will need to get your own wall unit. Good news is this is the future. Should remain the standard for a long time.
A:AnswerNo they do not. These do not have multipoint pairing as I just bought them and am disappointed. My Jabra 75t have this feature that apple/beats have chosen to leave out. Whomever answered from best buy and said you could switch was wrong. You have to manually connect in your Bluetooth settings every time you switch devices as it will not switch automatically.
