Electronics.Woot is offering the Sony (MDRXB950BT/B) Extra Bass Bluetooth Headset for $99.99 + $5 flat rate shipping. That's half-off the original list price/Amazon's current listing and the lowest we can currently find for them (We did see them for $98 back in November). 

They feature Bluetooth and NFC connectivity with apt-X support, a built-in microphone, 40mm drivers and up to 20 hours of playback on a single charge. Over 500 Amazon shoppers gave them 4.5/5 stars.
