The instructions have setup guides for all Bose sound bars. The machine dries pair no longer fit as well and lost some of its staying ability. Good noise cancelling and case. I am the sort that needs a permanent hook in the wall not one that falls off. The instructions are clear about taking care with the retraction of the earbuds and they are the best deal I’ve found in a long time. They were easy to install, perfect in daughter’s room. I wonder how many other reviews are "inflated". I got a few from other companies and they were the same color all the way through. Do not waste your money on the overpriced shotgun seat, this product is exactly the same for less than half the price. They are a bit pricey but worth every penny.
