Headphones not used much and kept in the case and in excellent condition. Took forever to connect with customer service. The warranty has expired and now they won't do a darn thing about the malfunctioning bluetooth. Even after troubleshooting, they do not work and Bose is offering to replace them for another $200! I find their business practices abhorrent and want to make sure everyone knows about this! There are way too many competitive products to choose from out there. Bose will not be getting any more of my business!
