Turtle Beach Ear Force X42 Wireless Gaming Headset (refurb) for $19.99 + $5 shipping
This is on Woot.com and shipping is $5 flat per order.
I don't understand the pricing of this and it could be a mistake because Woot also has a "Factory Reconditioned" version of this for $64.99. I don't understand the difference between refurbished and factory reconditioned and why one is worth so much more.
I have several pairs of Turtle Beach headsets (but not these) and like all of them. I'd definitely get these if I didn't already have an embarrassing amount of headsets. For $20 you can't go too wrong on these. They actually trade-in at Amazon for around $20 anyway, so you might be able to get most of your money back if you don't like them.
