Just did loads of research into these and ended up buying the XM4s because every honest review said that all the new features on the 5s were just gimmicks that added nothing but complications
They're absolutely fantastic headphones, but fuckin hell, I wish I could disable the play/pause double tap, and switch it to the custom button.
The amount of times when you have the headphones round your neck, it brushes your chin and restarts playback 😡 Not so bad with music, fuckin infuriating with audiobooks
