Why This Hinge Breaks

The QC35's headband swivel hinge is a thin, injection-molded plastic arm that takes repeated twisting and flexing every time the headphones are put on, taken off, or folded for storage — a high-cycle wear point with very little material behind it. It's such a well-documented failure point that Bose doesn't sell the hinge by itself; the official fix is a full replacement headband assembly, which is why one small broken piece so often sidelines an otherwise working .
