Query: Minimum Range, Excellent Sound

The range on these things is terrible. I suggest putting the receiver up high with nothing blocking its path on any side to maximize the connection; this includes walls, cats, and furniture. That being said, the sound quality is absolutely great. It's like a surround system hooked directly to your brain. Some people complain about a hiss, but that only happens when you're going out of range.
