The $299 Wren V5PF was the most attractive Play-Fi unit I tested for this roundup, and easily the most accurate in its sonic reproductions. It uses the first-gen Play-Fi chip, which supports only 2.4GHz 802.11, but the V5PF streamed just as well as units with the newer dual-band module. Once you've joined it to your local network, you can return your other devices to your faster 5GHz access point.Wren's Web site would have you believe that the V5PF is an Android-only device, but that's no longer true.
