The iDM11 has a boxy design (it looks a little like a miniature version of the) with a corner shaved off so the speaker sits at an angle. It's pretty stylish (I liked the blue light at the base) and feels well-built. This is arguably one of the better-designed products from iHome I've encountered in recent years.
You could put the iDM11 anywhere, but its design lends itself well to a home office, and the inclusion of a built-in microphone means you can use this as a speakerphone like you can the Jambox.
The iDM11 is compatible with all smartphones and devices that are Bluetooth-enabled (A2DP); we had no problem pairing an iPhone 4S with it. As with other Bluetooth speakers, you can range about 30 feet away from the speaker before you start to lose your wireless audio connection. There's a volume control on the speaker, but most people will choose to set that at the highest level--or near it--and control volume from a phone or other portable device.
