We suggest you use a mini audio speaker to turn your music device into a more portable one (for example, with the Akai MPC 500, the Roland SP 404 series and other battery-powered devices that lack their own speaker). I would like to note that for some devices you will need an adapter from 3.5 to 6.35 jack. I also want to note that a small audio speaker will not replace larger audio systems, monitors, and studio headphones.
