iMainGo is a new combined portable speaker and iPod bag that punches out the kind of sound quality you'd expect from systems of a much larger size.

The product is being distributed in the UK by AM Micro. The system's outstanding sound is the result of three years research and development, which has created a tuned speaker system which also integrates a digital amp and high output speakers.

The case provides some protection for your iPod, though it zips shut so isn't waterproof. It hosts an alarm clock setting and draws power from four AAA batteries — the manufacturers promise 30-hours of playback from one set of cells. The case connects to the iPod, (or other devices) using a line-in jack.

iMainGo is available online now and in high street shops by the end of the month. It costs £59 (including VAT) and comes with a one-year warranty.
