Bluetooth Portable Speakers. What's a good buy?

Or alternatively, why sit two feet from your wireless speaker with your phones battery draining from the bluetooth power demands, listening to slightly worse quality music, as opposed to having a double ended jack plug connecting the two?

You really don't get my OP do you?

To remind you. I have a 5.1 system that does FLAC.

I want a bluetooth system that has a good sounding portable speaker.

So the criteria is: Bluetooth, portable bluetooth speaker, a system that does bluetooth, bluetooth, bluetooth and a bluetooth system.
