Musical Music: The Accordion Travel Speaker
Speakers are useful in all kinds of situations, especially for travel. But traditional speakers are clumsy to fit into bags or suitcases, but these are designed for folding up and taking with you wherever you go: The Accordion Travel Speaker.
The white speakers are said to have powerful sound, and can stand up in any position needed. The hinges are strong and keep the speaker open, and it has several power options to keep it running longer at a clip: you can use USB power from a computer, or 3 AAA batteries; whatever works for your situation.
It includes 3 speakers and you can pick up this handy speaker setup for $14 from Urban Outfitters.
