I have a iPhone X and i love music very music. I need a sport Earburd which can easy connect to my iPhone, so i can enjoy fantastic music or make clear phones calls without the hassles of a dangling cable.
My favorite sport bluetooth headphone set are the Bose SoundSport Free. Best sound I have found in a completely wire free headphone. Slight video lag with the YouTube app but YouTube through the Safari browser is fine along with other IOS video apps.
