Best Buy offers the Sennheiser HD 4.40 Over-Ear Bluetooth Wireless Headphones for $99.99 with free shipping. (Amazon has them for the same.) That's tied with our mention from two weeks ago and the lowest price we could find by $50. These closed-back headphones feature ear-cup mounted controls and mic, 25-hour battery life, 18Hz to 22KHz frequency response, NFC pairing, and Bluetooth 4.0.
