Where sound quality fails to impress is at higher volumes. We feel that if an all-in-one system such as this can go up to a certain volume, it should perform well at that volume. Loud music lacks the definition we were expecting. Less complicated music is slightly better.
It shouldn't be overlooked that this is a system that is clearly built for convenience, not amazing sound quality, and as such, you should simply be aware that an ultracompact system like this just can't perform the way bigger, even similarly priced systems can.
While we appreciate that the overall design of the slim Size 0 is solid, the iPod docking unit is somewhat fragile-feeling. The dock is both a stand to keep the system upright and a typical iPod dock.
When closed, it folds away neatly into the system's body. It's a neat concept but practically, the dock's 5mm rotating cylinder doesn't reflect the solidity the rest of the unit exhibits. This is especially important to note if you'll be taking the system on rough-and-ready treks -- tiny plastic components are known for their stand-up ruggedness.
The Size 0's incredible lack of body more than justifies its unimpressive sound performance, and sets it in the niche of truly ultra-portable dedicated iPod docks. At £40 it's reasonably well priced as long as you don't treat the fold-away docking too badly.
