This versatile amp-style MP3 speaker contains a premium-grade speaker unit - so your tunes come through crystal clear and loud enough to rock a party. The three controls adjust volume, treble and bass. With USB cable to power the speaker and an audio cable that works with most MP3 players.
Can also be powered by battery for times when you're far from a computer (or in the middle of a muddy field!). Alternatively, connect to your PC with the audio cable and use as a computer speaker.
