Koss Sportapro : Lunlun's user review
I use it since around 1997 ... I love the big sound of this headset and foldable headband, which I regret is that some component is not more rsistant especially the cord. I tried many portable headphones for, but the only thanks I found my ears. This headphone rating 80/90, but the quality of the justification for the restitution REFERENCE absolute headphones for portable devices ... Looking back I think I would do the same choice even if I can find a cheap: /!
