Be careful throwing around these, though. Amazon reviewers repeatedly mention cheap build quality. I wonder what kind of warranty protection we will get on free headphones, too.

Their own website differentiates between the current and the 2012 models. I'm not sure what the differences are but they have 2 individual listings. Maybe they did something to improve the build quality in 2013? Just a guess.
Don't forget to check out Velodyne's skin collection for their headphones. A steal at only $40 each.
