The variety of options and uses included in the Coolstream Duos small package is what makes this product a winner.  Whether it is bringing new life to your older 30-pin speakers or bringing Bluetooth to your car via the AUX jack for the price you can’t beat it.  Upgrading to Bluetooth on any of these products would be expensive but with the CoolStream Duo you can upgrade both for $39.99.
