Princeton unveils the PSP-312IPB, a portable 2.1 channel speaker system for digital audio players. Using the included adapter, this system is compatible with all iPod models including the Nano and Mini. Good news for those who do not own iPod’s, you can even use this system with other players using its stereo mini-input jack, it just won’t fit inside the dock but you get the same effects. It features a built-in amplifier with 3W×2 output and a 6W subwoofer. Even more surprising is that on a single AAA battery, you’ll get up to 25 hours of continuous use. These speaker systems will be available later this month in Japan at the price of $82 USD.
