Sergio USA’s iSpin is a dual iPod-docking mixer with an included headset and the ability to modestly process two iPods’ music prior to outputting it to speakers. The device is probably more suited to a house party than a club. It provides a range of effects including reverb, flange, hi/low pass filter and scratching sounds. The iSpin won’t suit everyone because you can’t beat-match with it. Available in silver on white or red on black, the iSpin is priced at $140.
