Owners point the Bose QuietComfort Ultra Headphones (2nd Gen) at frequent flyers who want quiet on a plane and a case that fits a carry-on, and glasses wearers and anyone whose head hurts in tighter-clamping headphones.

The most-cited downside of the Bose QuietComfort Ultra Headphones (2nd Gen) is a background hiss or white noise floor with nothing playing, audible to many owners though not all. For the Grado SR80x, it's glued-together build (drivers, gimbals, rodblocks, headband) that owners view as flimsy, breaks over time, and often requires DIY hot-glue or aftermarket-part repairs.
