The iHome2go is a small audio system that allows you to plug in your iPod and play through the speakers. It is very portable if you have the appropriate battery in place, otherwise runs off of AC electricity.
I personally adore this little powerhouse of a speaker system. The design is sleek and slim. It has a remote, which I can use to change songs, volume, or mute the sound. I keep the player in my kitchen, and that baby can crank! I love being able to carry the remote with me while I'm scrubbing the scum from my fridge, turn it up or down as needed, and skip the pesky songs that I'm tired of. The player comes with plastic adapters that allow you to use any version iPod, so it is very versatile. It also has a clock and alarm feature which came in fabulously handy when we took it on vacation.
These little beauties are inexpensive, easy to tote around, and lets you enjoy your iPod in a whole new way.
