The bluetooth_connectivity
~1 in 3 long-term reports mention a failure, spread across bluetooth connectivity, ear cushions, and audio output, typically appearing within the first 1–13 months. Warranty outcomes are nearly split: 37 resolved versus 36 unresolved, so resolution is not guaranteed. Serious failures run at 22%, just below the 24% baseline for wireless headphones we track — about typical for the category.
