Bose via eBay offers its refurbished Bose QuietComfort 35 Wireless Bluetooth Noise-Canceling Headphones in Black for $199 with free shipping. That's the lowest price we could find for another refurbished unit by $31. They feature volume-optimized EQ, Bluetooth and NFC pairing (aided by voice prompts), and a noise-rejecting dual-microphone. Note: A 1-year Bose warranty applies.
