We heard rumors of a beefed-up D2 way back in July, but Cowon has just now made that upgrade a reality, and it’s giving its iAUDIO 7 player a storage boost for good measure as well. Both upgrades will apparently only be available available on the red versions of the players, with the D2 now topping out at 8GB and the iAUDIO 7 pushing things all the way to 16GB. Otherwise, both players appear to be the same as before, with the former boasting a 2.5-inch LCD, an FM radio, and a promised 52 hours of playing time, and the latter packing a 1.3-inch LCD and an even longer 60 hours of purported battery life. According to Cowon, both should be available any day now (if they aren’t already), with the new top-end D2 running $250, and the upgraded iAUDIO 7 setting you back $300.
