The OontZ Ultra-Portable Wireless Bluetooth Speaker by Cambridge SoundWorks
I bought this for my boyfriend for Christmas because he really enjoyed using our friend's jambox.  The Jambox was out of my price range for this particular gift so the oontz was a great alternative.  I also found the Jambox to be rather quiet.  The oontz exceeded my expectations.  It is loud enough to easily fill a room, connects via blootooth very easily, and is quite portable.  Also, the device is designed to provide more bass which it definitely does. For the price range this is an excellent speaker that
