Product review (1 stars): Great Idea-Terrible Product
This product has great potential. To be able to change your voice and play a prank on your friends, or to use it as white elephant gift.

Unfortunately, this is not the case. I actually ordered 3 of them to use in white elephant gift exchanges. The first problem is that the headphone jack only fits a few phones; mostly older ones. The second problem was that the "adapter" really doesn't serve any function. Finally, if you have the correct phone and are able to get it plugged in, you will find that it still does not work. The person on the other side cannot understand a word you say. Even with the different settings, I was unable to to understood.
