Sent them back. Samsung has really gotta work out the kinks on that one. 4 stars because I havent worn them for a whole day yet but so far they are comfy! This is the first one that fit my narrow feet! These work okay. Im an ER nurse, farts are funny. Overall it is worth the price for protecting your AirPods and peace of mind knowing you wont lose them. I went up from a 7 to an 8 and I am glad I went up a size, they were not as big as I had expected so I am glad I went up one size. Also very worthy are the Kinks stereo albums (Lola, Muswell Hillbillies and beyond). The fit is completely different from the right and left shoes.
