Follow up: My daughter told me she wanted headphones and not earbuds, so I opted to buy Anker Q20 headphones for around $60 with a case.
40 hours battery life, Bluetooth 5, noise cancelling. No idea how good to NC will be, but it's a bonus as next week we are doing a 10 hour drive to Tennessee for a weeks vacation. Seemed like a good idea, and the battery life seemed pretty good.
Seem to work well so far with the Ipad Air 4
Have literally only tested them for a few minutes last night so far.
