The large is a perfect fit. Battery life so far seems good, and it is charged with a standard USB-C cable (supplied, but easily replaced should it get lost). Do NOT purchase this brand. Sturdy and perfect for a home gym bt not for heavy wight lifting. easy fit If one does not have the money, one needs the patience to wait a few seconds for the screen to rotate. Very easy to use and build quality beyond criticism. The sound you get is awesome and you get the bonus of great battery life and ANC in an exceptionally reasonable price. Muy contento y satisfecho con este producto. If you are looking for big bass boom gaming cans, these are not for you.
