"Noise Killer" Panasonic D-Snap SV-SD870N Runs 100 Hours Per Charge

Panasonic's latest D-Snap audio player, the SV-SD870N, is debuting (in Japan at least) with a trio of cool features, though no Bluetooth:
• It can run for "approximately" 100 hours without needing a recharge.
• It can record directly from music source to SD card when docked.
• It has built-in "noise killer" active noise canceling, so that, according to the loosely translated release, "the noise of the train is cut 83 percent at the touch of a button." [Press Release via Akihabara News]
