They have two models, an open and a closed. I'm curious about these as well, but they're not really available yet so I guess we'll see.
I'm curious about the pricing. People kept saying the AD700 is <$100, but I've never seen one at that price. If these headsets are in that price range, I suspec they'll do well.
They used to retail for that before they were discontinued. The new models are around $150 IIRC. These will probably pop up for $250 or more. I'd honestly be surprised if they were lower.
