They're shipping now and available for $59.99 and $69.99, respectively.
The spherical iDM8, which comes in black as well (for some reason iHome's only showing the red version on its Web site), seems to be the more travel- and bag-friendly. But, as you can see from the specs, the iDM11 has a built-in microphone and speakerphone capabilities, a plus.
We'll let you know how both models sound when we get our hands on review samples. But they seem decently priced and hopefully their street price will be a few bucks less.
