Review title: Didn't work for me
Product review: The Ebtech HumX didn't do anything for me.My home theater subwoofer buzzes when it is powered up. The loudness of the buzz changes depending on where I plug it in. This sounds like a classic ground loop problem to me.I bought the HumX and it didn't do a thing. Absolutely no change.Now I am stuck with the chore of filling out a form, getting a return number from the manufacturer, paying their restocking fee, and making a trip to the post office (paying the return postage myself). That is almost as annoying as my noisy subwoofer.
