Considered one of the premier models, the Aliph Jawbone 2 Bluetooth Headset is now at BuyDig.com for just $64.99. This features adaptive noise cancellation, which adjusts your call's volume after measuring ambient noise around you. Note that it comes in OEM packaging, which means no pretty retail box and marketing materials, though it's otherwise identical. Shipping is free and there is no sales tax (except NJ). Compare this price to $130 at Jawbone.
