Got a whole roomful to impress with your first-person video blog of your African safari? Let them hear the trumpeting of elephants with louder, clearer sound by hooking up the Sony RDP-CA1 portable camcorder speaker to your compatible Sony projection camcorder. It works with camcorders featuring Sony's Active Interface shoe, which is how it connects and draws power from the camera — no need for batteries. Sound is dispersed in a 360-degree pattern, so that everyone can hear your masterpiece loud and clear. And it weighs all of 2.8 ounces, so it's as portable as your camcorder.
