iPod Karaoke Microphone

This device allows you to sing along with your favorite songs because it has a built-in FM transmitter that plays a connected iPod's songs through your home stereo system.

The device isolates and mutes the vocal track of the original song so that you can replace it with your voice, which can be easily heard over instruments and backing vocals; at the touch of a button the lead vocals can be added back in to help you keep your place.

It can also be plugged in directly to your stereo system using standard audio cables (not included).

You can pause, scan forward or backward, or skip tracks using the device, and add reverb to your voice.

Power is provided by a connected iPod.

6" L x 1" W.
