Logitech S315i

Logitech is no stranger to the world of iPod speakers, churning out both desktop and portable units since shortly after the time of the player's inception. The company hasn't varied sharply from its formula over the years, mainly making evolutionary changes to up the quality and functionality of the devices. The latest portable speaker, the S315i, offers iPhone shielding along with a power-saving feature to increase battery life. The $130 unit offers solid sound quality and a durable, compact design, making it a good fit for iPod owners who are constantly on the go.

Style-wise, the flat-black Logitech S315i is not at all striking, which means it will likely appeal to most eyes. It's nearly a perfect rectangle, save the slight pinching in the middle that adds a bit of curve. At 10.5 inches wide, 5 inches tall, and an inch deep, the unit will fit nicely into any carry-on bag or purse, though we are a bit disappointed that Logitech didn't include a case in the package--we've come to expect it from speakers in this price range. That said, the unit seems quite durable, with a sturdy flip-out kickstand that covers the iPod dock when closed and a rubber flap to protect the ports on the back.
