I've owned the digiZoid ZO for just a little while now, but it has really grown on me! It's the perfect amp for bassheads. It's pretty much an external EQ for your music player. It was absolutely fantastic using this listening to dubstep. The build quality isn't the best, mainly a bunch of cheap plastic but it's fairly lightweight so I'm comfortable throwing it around. It's really straight-forward as it only has one button which is used to increase/decrease the bass and power on/off. I'm not a huge fan of the colours as a measurement because it's not...
