I call BS, they were perfectly safe for the seller to ship to me but suddenly when they arent working I cant return them. The only gripe I have with Pop-Filter is the mesh. These sneaks are the most lightweight I?ve ever owned and it?s an awesome feeling when jogging! Overall though, very good price and quality. Anyone that has had a bad experience with the Wiwu case, I imagine if you made your dissatisfaction known vocally, either here on reddit, or on Amazon, Marlon has probably reached out to you already. Maybe its just me. Bought this for my son, whos off at college in his own apartment. If you have wide fat feet order up a size. Proper positioning in the ear and use of the right size rubber ear cups are required for good sound reproduction and noise cancellation, but this is not unique to the B&O. Returned it once after the connection failed and the same thing is happening again barely two months later.
