I'm happy to say the 6000 really does exist.
I picked one up yesterday from JP's shop, The Outback Prospector in Clermont.
First impressions, well packed but not ridiculously entombed in plastic, nice and light.
It takes a few hours to give the battery full initial charge so allow for that when you purchase one.
Bluetooth headphones are nice quality and charged fairly quickly by USB from my laptop.
Looking forward to using it in the paddock but need to wait a couple of days till my knee fixes itself.
