Bose Corporation

I bought my first BOSE product over 25 years ago, BOSE 901. Was hooked on BOSE ever since. I have spent thousands on BOSE since the first purchase. I bought my first pair of BOSE noise cancelation headsets many moons ago, I LOVED them. About 2 years ago the foam on the ear pieces were worn due to use, but the headsets still worked great. I called BOSE looking for replacement parts, they talked me into upgrading to the Bose QuietComfort 15 for a real great price, I thought it was great so I upgraded. My traveling has been minimal these last couple of years, on my last trip the headsets stop working all I get is a bunch of noise. Again I called BOSE explained and allowed the BOSE rep to hear my headsets, he said that the noise cancellation had gone bad. I could replace them for the identical QuietComfort 15 for $ 100 or upgrade to the QuietComfort 25 for $ 200, I am very disappointed that I will have to spend this kind of money so soon. I own a lot of BOSE and as such very disappointed.
