So I am now hating them for the stench. The phone itself is fantastic. My previous pair of headphones (the JVC gummy brand) were OK for awhile, however, they eventually started causing severe pain in my ears after sleeping with them--to the point that they were chaffing the insides of my ears. Me han gustado mucho 5 crosstrainer. Definitely copper as the other reviews said. I dont foresee myself having that issue after having this on my counter for a few weeks. Fits all my shoes perfectly. That said I have heard that compared to beats these have very little bass in comparison. I have wore them for about a week and they seem to be comfortable, I had to get a size bigger.
