I tried out the Monster - Monster Basics Sound Reactive Multi-Color LED Light Strip.  The color was great.  It was only 6 ft long so you would need multiple strips to put around a tv.  I tried it around my tv but need to get more strips to fit it all the way around.  An issue i had was with the remote.  It has to be in line of sight or it won't work. So if you're doing what i was want to do is have background lighting around my tv it can't see the remote to work.  Other than that issue it was a great product.
