Maybe it's just me but using these while exercising makes the Buds 2 not stay in my ear properly. I wish Samsung would make an add on to keep these on your ear. For example, a hook to go over your ear. These are the best earbuds I've used as they are reliable as far as charging and not randomly connecting to my phone while in the case. The sound from them is great too. But come on Samsung! When you move your jaw, it does affect your ear canal. Do better and make something so I can use these for all activities.
