Logitech’s Z305 Laptop Speaker is not your regular two satellite speakers, or two sats and one sub. It’s like a very, very small version of a soundbar-style of speaker.
The Z305’s dimensions are 324 x 40.3 x 41.8 mm (H x W x D), and it can either be placed laying down, or clipped to the lid of a notebook or netbook computer.
There’s no need to carry batteries or a power cord, it’s powered through a computer’s USB port. The Z305 also has a standard 3.5 mm plug, just in case you run out of USB ports, or want to plug in an iPod / AV player.
Included in the box is a travel case and USB cable. For neat travelling, the USB cable tucks into the back of the Z305.
