Secondipity via eBay offers the refurbished Sony MDR-1000X Premium Noise-Canceling Bluetooth Over-Ear Headphones in Black for $179.99 with free shipping. That's tied with our mention from three weeks ago as the lowest price we've seen. (It's $68 under the best deal for a new unit now.) They feature 40mm high-sensitivity drivers, frequency response of 4Hz to 40kHz, 20 hours of playback, microphone, Bluetooth, and easy-touch controls.

Note: A 90-day Sony warranty applies.
