I like the concept of these but they really need to be wireless and Bluetooth if they wanna take over the fitness marketshare. After using a really good wireless Bluetooth and sweat proof headset like jaybird, there's no going back to a wired headset IMO. I'm guessing price and battery life kept them from doing that, but that's too bad.
There is a wireless version coming out they just got delayed. the On-Ear Wireless Sports versions are out though.
