Let everyone enjoy music at a party with the Sony MHC-V11. Via Bluetooth, you can stream music wirelessly from a smartphone or tablet to the battery speaker. Stream your favorite song and connect a microphone to sing along. You can connect 2 microphones at a time, after which you compete against someone in a karaoke competition. The built-in vocal fader function turns the vocals of a CD down, so that your voice comes out more clearly. Thanks to the Party Chain function, you can connect several speakers together that have the same function. This way, you better distribute the sound over a room.
