Looks like the out of court settlement between Bose and Apple-owned Beats over patent disputes wasn't the final straw in the on-going battle between the two companies, as Apple has now removed Bose products from its online and retail stores.
Models from other brands like Sennheiser, Bowers & Wilkins and Marshall are available for purchase, suggesting that the removal is a more targeted effort centering on Bose's offerings. The two companies locked horns recently over an NFL sponsorship deal that forbade players from wearing non-Bose headphones during press conferences and any on-camera events. Beats' co-founder didn't seem to mind the coverage, however, stating that the ban generated a lot of free publicity.
Regarding the removal of Bose's products, an official statement wasn't provided by either organization, although with the on-going series of conflicts, you're better off looking elsewhere for the QuietComfort 15.
