Imagine this: you’re at a karaoke competition. You grab the microphone, belt out your favorite song, and the crowd goes wild! Everyone can hear your voice, thanks to your handy dandy microphone.

Send it to us at BrainsOn.org/contact, and we’ll find an answer that really ampsyou up! See omnystudio.com/listener for privacy information.
