Twice the speakers. Twice the sound. In general, portable speakers that are designed to go places offer less-than-impressive sound. The Ivation BOOMER is aiming to change that in a drastic way. As the FIRST TRULY STEREO bike music streamer, it brings the bangin' with two 33mm speaker drivers. What's more, they are separated by design to fire in opposing directions, thus achieving an intelligent Omni-directional audio spread. This allows for better focus on individual music frequencies and clearer, more accurate audio reproduction. Cables? In the 21st century? When Ivation says portable, they mean portable. So forget about auxiliary cables that just get in a tangle at random. The BOOMER relies on the latest Bluetooth technologies for a completely wireless streaming experience that is as reliable as it is clear to the ear. Once you connect your mobile device, you can play music without any cables and control playback, song selection, volume, and even phone answering right from the softclick button panel on the speaker. Incoming calls automatically pause the music, and a built-in microphone lets you chat while you chill. Made for the go. Inside and out. While perfectly suited for home and office use, the Ivaiton Bike BOOMER is aptly equipped for adventure. A large capacity 1200mAh rechargeable lithium polymer battery ensures that you can juice up virtually anywhere: Just connect the included micro-USB cable to a computer USB port or use an AC adapter and plug into any wall outlet. And on the outside, its covered in a durable rubberized weatherproof enclosure. Included with your purchase are two types of speaker mounts that attach easily to everything from a pole to a beach chair to a bicycle. So crank up the volume, and take the BOOMER wherever your music takes you.
