These speakers are darn near as small as the Ipod! These speakers would be great for traveling since you can pack them in your pocket! Perfect way to enjoy your music while you're staying in a hotel or as a guest in someone's house.
I have this & it's awesome for outdoor activities. I take it to the tennis court with my iPod to have some of my tunes liven up the place. In fact, I was asked to have the volume turned down....I'd say that's pretty good output for a portable speaker.
