The powerful little speaker has Sony's Extra Bass tech. So not only are you getting a blast of music, but if you really want to be the life of the party you'll make the floors vibrate with an extra punch at the low frequencies. Don't mind that so much? Turn it off just as easily! You can also pair two of the same speaker together, whether you just buy two outright or you match up with someone else's. This allows you to play music in stereo sound instead of just mono, which is pretty cool.
