The Bose Noise-Canceling 700 Over-Ear Headphones normally list for $379, but you can get a factory-renewed pair for $279 with free shipping at Bose. This is $50 less than the best price we found for a new pair anywhere else. The Bose 700s have adaptive microphones and feature adjustable levels of noise cancellation. When paired with select apps, they can use Bose's Augmented Reality technology that will create a custom audio experience using motion sensors and location data. Sales tax is charged in most states.
