YOU CANNOT USE THE CHARGING BRICK THAY COMES WITH THE IPHONE 11 PRO MAX. Maybe size up. So I’ve ordered and returned a lot. Ive owned a total of 5 of these of the past 8 years. Isotoner used to be a good product. I would say go down a size though because I had to re order them a size down. However the Parrot bothered my right ear and after two years the seams started to unravel. I really like the detachable liner too, it will be great for traveling and personally, if someone asks me to go for this product then I will give a BIG NO as if this is happening with me then I am pretty sure it will happen to anyone else also. My biggest issue with the headphones are that the left side constantly blacks out with silence at the gym.
