I have this tiny MP3 player made by Sansa that I like a lot. Enough that I might buy a couple more to replace the one I have now when I break it. Which I will do inevitably. But it does not have Bluetooth. So I have been looking at Bluetooth adapters. I can buy very small adapters that plug into the USB slot on my computer. The ones I have work very well over the approximately 15 foot radius I use them in. All the ones that will plug into an MP3 player use the typical 3.5mm jack and are quite big. Larger than my little MP3 player. A large portion of that size must be the battery. So I am wondering if it will work with an MP3 player to power a USB Bluetooth adapter from the MP3 player battery. I know that the battery life will be shortened by at least half but I can live with that. However, I suspect that the real reason that USB Bluetooth adapters are so small is because the computer it plugs into is doing more than sending and recieving data from the adapter. I suspect that the Bluetooth transmitters that plug into MP3 players have some sort of encoder that turns the analog audio from the player into a digital signal that it transmits. Are my assumptions correct? Thanks, Eric
