Make:

I pretty much use an iPod Shuffle and the counterfeit version (called the Super Tangent) for most of podcast / music listening. Lately, I've been hitting the treadmill to get rid of those 10 "conference pounds" one gains from going to technology events. If I jog, I can just slap the shuffle or shuffle clone to the armband, but downstairs I've been looking for a small speaker system that I can move from one side of the room or another depending on what I'm up to. I hacked up a couple solutions, but I thought I'd try out the $39 Griffin TuneBox.

TuneBox Features:

• Total power output of 2+2 Watts for amazing power and volume
• 3.5mm jack input (compatible with other MP3 players and devices)
• Stylish design that complements Apple's award-winning industrial design
• Functional design keeps shuffle controls handy
• Dimensions: 4.32 inches x 2.44 inches x 4.4 inches
• DC power cable for use in office or home
• Slim design AC adapter fits easily on crowded power strips or wall outlets
• Input: 100-240 VAC 50-60 Hz 0.5A
• Output: 12VDC 1.0A 12.0W

Plugs in via AC, but I think I'll be able to make a battery pack pretty easily.

The USB dock section, plugs right in and charges the shuffle or shuffle-like device.

The audio out plugs in to cable and then that plugs in the side.

Downstairs, running and it's pretty loud- I only listen to spoken word, audio books and such- but it's slammin'.

Here's the Luxpro shuffle clone, it also fits perfectly and since it's an FM tuner, this doubles as a radio!!

Perfect fit.

So that's about it- simple, loud, works, small not too expensive either. Griffin's site here.
