MM 28 Portable Speakers
Logitech's mm28 portable speakers are one of the thinnest portable speaker available - less than 3.2 cm thin. Powered by NXT flat-panel technology, the entire front surface is a stereo speaker that produces rich tones and lush bass. The 3.5 mm input jack (which stores in the back of the speaker when not in use) means it can be used with MP3 players, CD players, DVD players, PCs or anything else with a standard headphone jack output. Flexible power options include an international power adapter as well as 4 AA batteries (not included) capable of 45 hours of battery life. Goes anywhere. Use with anything.
