Q. What is the best speaker system?
A. The one that you use and enjoy the most.
Going by that logic this little £12 speaker is the best hifi that I've ever heard. It consists of a little 40mm speaker with built in battery powered 2.5 watt amplifier. OK, it's mono only and it's never going to do deep bass or extract every last ounce of detail from your music but it does go surprisingly loud and deep for it's size and you can actually hear enough of the low frequencies to tell what the bass is doing. The quality's good for the price too and is a step up from the freebe speakers that come with computers. Everybody who's heard it has commented on how good it sounds and how loud it goes.
What makes it so great is how much use it gets. I use it every day at work, it's been camping with me, it's been used as a make shift car stereo, it gets used in the garden, the kitchen and even the bathroom. When it's not in use it folds up concertina style so that it only takes up two thirds of the space and comes in a little carry bag.
It has a built in battery that takes about two hours to charge by USB socket and it just seems to last forever. I usually get about fifty hours use out of it between charges. There's also a 3.5mm socket so that you can daisy chain them if you want more volume (though I doubt you'll need it).
So, there it is. If your looking for a portable speaker to use with your MP3 player or phone the X-Mini II is exellent. When I bought mine I wondered if I would ever use it. It now goes everywhere with me and gets about 30 hours use per week and I've bought a second one so that I can have one at work and one at home.
