TechRabbit offers the Jaybird X2 Sport Bluetooth Headphones in Alpha Green, Charge Green, or White for $89.99 with free shipping. That's $90 off list and the lowest total price we could find, although we saw them for $10 less in October. Designed for running, these sweat-proof headphones feature up to eight hours of playback per charge and include three pairs of silicone tips, three pairs of Comply foam tips, three pairs of fins, and a silicon carry case. Deal ends December 26.

Note: It's unclear if they will arrive by Christmas.
