Jawbone JAMBOX Bluetooth Speaker

Another popular portable speaker is the Jawbone JAMBOX, which, at 6 x 2.2 x 1.6 inches, is nearly as portable as the palmsized devices above.

It offers good sound for the size, and can also be used as a speakerphone.

A unique feature is the ability to update it with apps, software, and new features via Jawbone's MyTalk portal. Plus, it’s available in several colors.
