One thing you can always count on from CES, lots of accessories and misc devices to augment your existing gadgets. And the iPod has never been one to feel left out in this regard.
Yesterday, JBL, a long time player in the iPod speaker game, released a slew of new devices, one of which happily displayed playing nicely with the iPhone. Pictured right is the newly released Stage 400ID. This gorgeous sounding device come with with four Odyssey drivers and a built-in sub. If that is too much sound for you to handle then there is also the 200ID with two Odyssey drivers and no sub.
As usual with CES, no international release dates, but I am sure you could easily pick one up from the States online if your really keen.
