got these with my new s21 5g and was looking forward to me (espcially since the s21 doesn't have a headphone jack), but i can't get them to stay in. i've tried the different tips, read the "how to wear" article that has been linked in other reviews, and watched a video with no success. even as i type this, the left bud is popping out of my ear. so disappointing. there is no possible way i could wear these at the gym or any other location/activity with constant motion.
