BOSE; Defective Upgrade?

I called BOSE earlier today. A local BOSE store. I told them about the QC2 earmuffs are wearing off and black marks are appearing on my ears and neck. They said I could have earmuffs replaced OR have the headphones replaced for the NEW QC15 HEADPHONES. The part I did not hear was whether I could trade my QC2 in for 100$ or 100$ OFF.

Has anyone had experience with this situation? I would like to know if I trade in my QC2 for the new QC15 for 100$ or 100$ off. Thanks

 

Really? Why? The QC15 are made of better material and cancel out noise better. It's the upgrade from the QC2.
