Review: Works great. I was able to relocate my subwoofer wirelessly. - This works great. Our house is full of WifI, cell phones, etc, and there seems to be no interference. I am running a subwoofer remotely so "sound quality" is hard to hear, but it sounds fine to me. (low frequencies are easiest to reproduce, so it is probably fine) One thing, it does introduce a delay. When I ran my receiver speaker setup the apparent "cable length" of the sub woofer was pretty long. Fortunately most good receivers can compensate the timing for things like this. The delay might be more of a problem for high frequency speakers (like front / dialog) if your receiver can not adjust for it.
Review: Great way to move your sub woofer - I didn't know these existed. They are great. You turn them both on, they pair immediately and i was able to move my subwoofer behind my couch. Out of the way, and it's cool feeling the couch shake during a movie. Use a high quality speaker cable that plugs in to LFE.
