The Harmon Kardon Go + Play portable speakers system is one of the more expensive portable iPod speaker docks, but is well worth the price. It offers the flexibility of running off of AC power or batteries for a truly portable solution, and the volume and sound quality necessary for listening in a larger space. Take it to the beach, in your back yard, or to the park and you will always be able to play your music for everyone to hear.
Although designed to work with iPods including the capability to charge and remote control the iPod, the Harmon Kardon Go + Play system also features a 3.5 mm input jack that makes it compatible with any digital audio or MP3 player on the market. Of course you will lose some features such as charging and remote control capabilities but you never have to worry about it’s ability to work with any audio device you may encounter.

As for sound quality, get ready to be amazed at how crisp and clear the sound is coming from this small system. Turn the volume up and you will swear that it is coming from a much larger set of speakers when you hear the deep bass notes and crisp highs without any of the distortion common among smaller systems. It also doesn’t hurt that the system sports a clean design and well integrated carrying handle for the ultimate in portable speaker systems. The numerous positive reviews at Amazon further attest to the sound quality.

You can the Go + Play at a good price both at Amazon and eBay.
