I was not liking it at first but got used to using it now since Xmas, but they do slip out ear from sweat etc. I am afraid they will drop out get damaged or lost which makes me wish it had strings lol but now I am more cautious as to where I use it and when. The two prongs I guess for magnetic hold in case does hurt inside ear....to add to it now the sound sucks after some updates it sounds cheap now🤔....I would watch Netflix and Disney on Samsung galaxy phone and I have had frustrating sound
