It's still full price at Amazon, Best Buy and Newegg for $329.99. Don't think it's been this low before.
There is also a 15% coupon at the site but will not work on discounted items such as this.
As for the headset, it's pretty much the full package. Swappable batteries and added bluetooth are the two biggest perks/upgrades from the previous model. It has some shaky reviews though. I'm still on the fence myself.
