Roth launched two new products at the show both supporting the portable media market. They are called the Charlie 2.0 and the Charlie 2.1.

Both are available in black or white and feature a duel concentric design driver for optimum sound performance. They have a built in amplifier and a wireless receiver for receiving signals from their wireless iPod dock.

Both are unique in design, simple to use and have inputs for USB and Analogue via a 3.5mm stereo jack for direct input from your phone, media device or PC.

The Charlie 2.1 unit features the same design but comes with a sub-woofer to enhance the response from anything played through the unit.

Both Charlie 2.0 and 2.1 are available from April 2010.
