Bose QuietComfort Headphones for Sale The headphones are in excellent and clean condition, with great sound quality and Bose's renowned Active Noise Cancellation (Noise Cancelling) feature. Features: • Strong and excellent noise cancellation for travel and work. • Long-lasting battery. • High comfort for extended use. • Stable and fast Bluetooth connection. I bought the headphones on a two-day trip and tried them, but they didn't suit me due to ear pressure as I'm used to larger headphones. The headphones have been used very little. **I couldn't find the invoice, so there is no warranty.** New price on Amazon is 650. Starting bid is 300, within reason.
