Review: Works great
Review: I misplaced my calibration mike years ago...needed a replacement as I've changed speakers and added a rear channel. This microphone was identical to the original, and after calibration, my system sounds great again! I did trip over the signal wire twice because it's thin and black and I was preoccupied. Might be better if these were made in day-glow orange!

It worked for my Sony amp and an Onkyo amp I calibrated so no complaints here. Much better than doing it manually.
