Portable speakers in a tube.
At 3.2 lbs and 12 inches long, this handy little pack of speakers can be used indoors or outdoors running on batteries to allow you to provide the same listening experience that you have with your music player on to others.
The speakers twist off of the ends of the center tube, and then wires plug into the back of the Boomtube center piece from each speaker. Almost any MP3 player can then plug into the back of the center tube from the headphone jack with the supplied cables to have your MP3 player music come through the Boomtube speakers.
The speaker kit comes with required cables and a carrying case, and the battery is rated for 5 hours on a full charge, or the BoomTube speakers center piece can be plugged into an electrical outlet to use and to charge the battery.
