This is one of the first wireless audio technologies to combine full CD-quality audio with ultra-low power consumption. Battery life lasts 10 times more than Bluetooth solutions. As a result, this product can utilize smaller batteries to achieve true compact form - without sacrificing sound quality. Small in size and weighing less than 10 ounces, revolutionary design and portability make it easy to mount on a bicycle stem or top tube, on a backpack and almost anywhere. Thanks to its groundbreaking technology, you can enjoy all of your digital music in unprecedented sound quality, and long battery life means you'll enjoy it even longer. This product also reduces the safety concerns associated with headphones or ear used in active outdoor sports like cycling, and it eliminates the inconvenience and hassle of stereo wires and cables.
