Review title: Griffib iMic
Product review: I found the iMic unusable for my intended purpose. Their advertising says it may be used with any microphone. I found that it would not work with the most common type of dynamic microphone. After several e-mail messages back and forth they advised that it would work with a relatively rare high impedance dynamic microphone.
