Review title: Didn't do anything
Product review: I bought this item to connect a microphone to my MacBook. It supposedly has line and microphone settings. I got no amplification of the microphone at all on the mic setting. It was just like plugging the mic directly into the computer. Next I bought an ArtTube preamp, which worked for one day and started crackling. Finally I bought a Blue Yeti mic, which works great.
