You can google the ear cup and mic muff replacements online all day. The actual band that connects the earcups might be found on a parts sale on ebay. After our accident I had to have one Bose X set repaired, the headband snapped in half and the ear cup itself was damaged. I contacted a guy in CA that would repair/rebuild the unit and it came back like new. I'm looking for his contact info and if I find it I'll repost.
