Absolutely gorgeous sound!
It just works and pair easily.
The sound is crisp and the bass just loud enough.
I put 5 stars to that product but I want to warn owners of Retina Macbook Pros.
The Spinnaker Speakers pair via Bluetooth and unfortunately rMBP are not doing well with Bluetooth and Wifi at the same time. (Same 2.4Ghz frequencies) If you are in that case and you don't have a simultaneous Dual Band Router at home, then don't buy these speakers because you will be disappointed.
Listening to music over Bluetooth while having to turn off your Wifi is very very cumbersome.
