The company's mm50 portable speaker system for the iPod simultaneously recharges the iPod battery as well as the speaker battery when powered by the included AC adapter. It can also run off the rechargeable lithium ion battery, which lasts up to 10 hours per charge, according to Logitech.
Speaker-techies might also want to know that the mm50 system uses "Max-X high-excursion drivers, which include neodymium magnets, as well as three-inch pressure drivers." And the added 3D stereo technology "widens the stereo image," enhancing the "audio experience," Logitech said.
The suggested retail price for the mm50, which includes a wireless remote control, is $149.99.
The mm28 speakers, aptly described by an Engadget writer has having "glass-case styling," are ultra-thin and use NXT flat-panel technology. They include an integrated speaker cover that rotates to become a speaker foot, so no carrying case is required, Logitech said.
The mm28 is powered by either the AC adapter or by four AA batteries. The speakers can last up to 45 hours on a single set of batteries, Logitech said. The system works with any MP3 or CD player with a standard 3.5mm audio jack, and has a suggested retail price of $79.99.
