Query: GREAT for travel

These speakers are super convenient. They fold up so it is easy for me to fit them in with the rest of my stuff, and the sound quality is pretty good considering how much I paid for them.The most surprising thing about these little guys is how long the batteries last. With a set of those long-lasing ones the speakers will easily outlast many charges of my ipod, even when set to a high volume.These come in most handy when I am hiking becasue they are cheap so I don't have to worry about breaking them and small enough as to not take up that much space.
