I bought the Belkin receiver as a means to get internet radio on my hi-fi using my Blackberry Curve 8520. The receiver is impressively small, very easy to set up and stays stable once connected and within range of the phone. In my opinion, sound quality is acceptable when listening to the low bandwidth and bitrate typical of internet radio. Switching to a higher quality music file, there is a definite loss in upper and lower frequencies as well as a slight "tunnel" sound.
However, for me, the purchase wasn't about buying a hi-fi product. It was about easily and conveniently exploring internet radio using my smartphone as both remote control and source and for this I award the receiver 4 stars.
