Bose QuietComfort Headphones — Buyer Complaints
- Crowded transit hubs and convention centers trigger the most Bluetooth complaints. The issue is usually phone-chipset compatibility, not the earbuds themselves. Check your phone model in the Amazon Q&A before buying.
- Real-world battery tests from 6-month buyers show 20-30% capacity loss. This is chemistry, not defect. Plan on replacing the unit in 18-24 months if you charge daily.
