Do you really have to have a Roku TV in order to use these wireless speakers. We have a Samsung TV that came with Roku app on it even though we have the Roku Express. Will the wireless speakers still work because if so I would love to get it for my husband. He always turns the volume up to 32, he says he can't hear but he wants a surround sound system. Please be honest and let me know if it would work on my Samsung TV to is not even a year old yet.
