When it happened with more than one set of headphones I assumed it was the cables. One being was one of the tools missing. The size is good, it fits my Dunk high. This one calls out PVC in the description but actually shows pictures of a foam buoy and provides foam. It has certainly done the job and I feel and look better. I guess I have a small head, or its a female problem, I dont know. I did not come across any major rain storms so I dont know how water resistant it really is, but Im pleased with this purchase. Its not uncomfortable in general (even after several hours), but it means that I cant use the ANC when I have a headache (one of the reasons I wanted ANC). They have a nice sole and are well made. These are good headphones.
