Bose’s article is explicitly for QuietComfort Headphones (2nd Gen). It directs users to the “QuietComfort (2nd Gen) Headphones Ear Cushion Kit,” says previous QuietComfort Headphone cushions are not compatible due to a design change, and describes the rigid flange snapping beneath the earcup tabs. Bose says all ten tabs should be visible after installation and that proper installation ensures a good seal for audio and noise-cancelling performance.
