Portable speakers are a popular new market, with young people playing music on the go both alone and with friends. The BR-1X is designed with a playful, casual look to appeal to this market, its major appeal being the sound chain: up to ten speakers can be combined together, horizontally or vertically, to achieve a better, louder sound experience. Other features include a robust, fabric hand strap, two styles of interchangeable, colorful silicone jackets incorporating integrated volume controls, wireless connectivity from a smartphone or MP3 player via Bluetooth, and “outdoor mode”, to address the issue of performance lag when used outdoors.
