My old beats by Dre Power beats could not handle my sweat from running / training after 1 year of physical heavy use it eventually gave up on me, but its not a bad product by any means in fact Power beats lasted me a total of 4. I always get compliments. But, I love the look of it! I wear them to golf and they work well, good grip and comfortable GREAT QUALITY. These should be on every try out list. And because of this issue, I have to order 2 pairs of the same shoe in hopes that out of the 2 pairs one pair will fit. I tuck the cord into my shirt so all that can be seen is a blue cord and yellow earplugs, no control or counterweight. and I have added them to my permanent rotation- with all of my other FitFlops! Worked fine for a month, started to lose sound quality in the right ear to which it was significantly quieter than the left, but still useable.
