I received this red carbon series wrap for my QC35 Bose headphones after about 3 weeks from ordering. Product was well packaged and appears to be of good quality. Included in the package was what I think is a cleaning cloth and what looks like 2 versions of the headphone outer cover wraps. What was not included was any type of instructions or guidelines. Not even a link to a web version of instructions. Even looking trough this website, I could not locate instructions. So, I tried installing as best as I could and I am really disappointed with the result. Maybe with some instructions I would recommend but as I received the product, I do not recommend this product for wrapping something as detailed as headphones at least.
