Here is a car karaoke system that lets you sing along your favorite songs through your vehicle’s sound system. Roxie is pretty easy to use. It has a specially designed microphone to capture vocals from all passengers while reducing feedback sound from your car’s speakers. Roxie has a pitch shifter to allow you to lower or increase the pitch of the music.
Roxie plugs into your cigarette lighter and lets you interact with it using voice commands. It should work with most music players on your iPhone or Android device, including YouTube and Spotify.[where to get it]
