Video Review
Pros:
Rotary control is super easy to use.
Auxiliary input accepts audio from any audio source.
Seriously clear treble and impressive bass in a small package.
Charges Zune player while docked.
RCA Composite outputs for audio & video output to TV. (4GB/8GB Zune excluded)
Multiple dock adapters to fit any Zune.
Looks like something you would see in The Batcave.
Cons:
AC power only - no batteries.
Rear transport handle is a little too short for a good grip.
Conclusion
The Kicker zKICK ZK500 for Zune uses 5" Full-Range Drivers, 3/4" Silk Dome Tweeters and an innovative 6" square passive subwoofer to deliver the best sound we've ever heard from our special edition Halo3 Zune. Setup and connection to a television is a breeze, and with an auxiliary input jack you can connect just about any other audio device to the ZK500. Highly recommended!
