"So what we've got here is a headset equiped with 128MB worth of flash-memory, that can stream audio over BlueTooth (from whatever source is transmitting the data). It also doubles as a headset for mobile phones and PC's, might you be interested. When listening to music stored on the unit's own flash memory, a battery life of some 7 hours is advertised; not that great. The battery pack's removable, though. Plus you get something that looks like a UFO to go with the whole package, which is never a bad thing." About $200 US. I don't get the point of putting a DAP in a set of bluetooth headphones. If I am looking for wireless, I am looking for a lightweight way of accessing the media on a separate device.
