Thank you for viewing. I purchased this last month for a trip, but I no longer have travel plans, so I am selling it. I only used it for initial setup, so it's practically new. The noise canceling is excellent, and the sound quality has that unique, enjoyable quality that is characteristic of BOSE. It has been stored in a smoke-free and pet-free environment, so there are no odors. I have confirmed that it works, and I have cleaned it with alcohol as a precaution. Please consider purchasing it.
