I am sub 200 pounds for the record. This is the perfect product for someone that wants to listen to headphones outside while exercising, but yet not be blocked from ambient sounds. This case does not impinge on the charging base and has a cutout for access to the charging port and aux input on the side of the unit. Bottom Line:__________I?ve tested both Bose and Sony in the past, and I can say that Beyerdynamic has to be up there as well. The first day I wore them I was on my feet All Day and was surprised they didnt make my feet hurt like my Bass Loafers do when I wear them . The connection to the base is very weak. Replayed song on another device, no problems. The padding on the headband is the least cleanable part. I took a chance on these buds after seeing so many mixed reviews of other units in the same price range. It is too roomy in the back, and my heel slips in and out of the shoe every time I take a step.
