Dwarf Omni-Directional USB Speaker
Looking like anything but, this little USB speaker is capable of 360 degrees of sound output. Priced at $25, this could be a great addition to your set-up, especially if you don’t have a lot of space to work with.
This speaker could also be used apart from computers and placed in the center of the room for conference calls and such. In addition to the omni-directional feature, the speaker also vibrates to help deliver its sound. I question just how much bang this thing can produce given its small size.
