Speakers allow you to dock your MP3 player into a system and stream music via the stereo component of the speaker. MP3 speakers come in different shapes and sizes from the ultra slim and compact to larger units that can be placed in homes or at the office. Speakers allow your MP3 music including VIVO to be streamed instantly for a great party or for simple background music wherever you are. Portable speakers can be either plugged in into any wall outlet or can even run on batteries for the utmost convenience. If you store all your music on your MP3 player then it is easy to get a speaker and have all your music available instantly the minute that you dock your VIVO into it.
