Which one has the best sound quality? The cons for the Companion 5 is that it has static noise even when there is no music source, and it can not be eradicated. But the Companion 5 has an acoustic module so that I suppose it might be the best? The cons for bose ipod soundportable is that it might have the worst sound quality? But it's portable so that you can enjor the music everywhere. I am afraid this product may be overpriced. The radio wave system, as you can see, can only play radio, but you can make it a computer speaker if you got a cable OR you purchase the wireless Soundlink. But is the wave system as good as the Companion series???
