A:Answer I have yet to have any cracking problems with these. But, I have the previous model as well (the original 1000x) and haven't had any problems with them either. I use them daily and travel with them as well. I do keep them in the case when I'm not using them, could something have possibly happened to yours to cause them to crack? If you haven't already, it may be worth contacting Sony. These are a premium set of headphones, and they have lived up to that with me.
