I have three pairs of broken Beats Solo 3 Wireless that are broken. They all work fine with the cord, but won't charge/one side is broken, etc. One is well used, but two of them are in like new condition. I was wondering if I could buy a new set of headphones and return the other ones when they stop working? I know the beats have serials numbers but do they check to make sure everything matches, and I also have the old box that came with the broken ones as well. What do I do?
