This listing is for a used BOSE Aviation Headset X noise Cancelling Acoustic Model No. AHX-04 with Case. Item is untested and sold as is. On tear on the ear pad. Other than that normal signs of use. If you’re interested in more of these I have 7 and would work out a great deal for someone. The others don’t have cases and a couple of them have some small flaws but would give someone a great deal in all of them. Please reach out if you’re interested in the lot. Thanks for looking and as allway see the photos.
