Just bought some with the initial findings for anyone interested.

Price paid AUD 169.00

Tested against:

Sony Bluetooth Walkman
JasJar WM5 (failed)
Nokia 6120 classis
Nokia E71
HTC Touch Diamond
Sony Vaio X Series (Windows 7 took about 30 seconds to install divers)


Pros:

Combined speakers, BlueTooth adapter and batter power source
Good sound (not to audiophile standards)
Up to 8 pairings, attempts to reconnect to the last connected device
Play, pause, next and prev controls on the speakers
Strong signal, connection stability good with all, with exception of E71 which was mediocre

Cons:

Battery life is practically 4 hours (10 hours only with sub off)
bulky
