When it comes to desktop/workspace speakers, the Harman/Kardon SoundSticks are one of the best - I should know, I've got a set myself. They're quite a small set of speakers but with them having four drivers in each speaker the sound they give out feels a lot bigger than you would think. Whenever I've had friends round they're usually very surprised at how this small set of speakers give out such room filling sound. The sound is also very high quality it's on par with Bose's Companion's 3 and 5. Bass is also super smooth and no way over powering, of course the bass is also adjustable.
Harman/Kardon are now offering the SoundSticks III with Bluetooth functionality for true wireless sound. So you'll now be able to stream music wireless from your phone, tablet or computer. No having to mess around with a 3.5mm headphone jack, have all your devices connect when you like.
