The Koss Porta Pro I use for almost 10 years. I almost do before any music division halt, my headphones with a wide frequency bandwidth, clear highs and good bass were particularly important. If you want to headphones along with players often have when it is finally a question of size. The first Porta Pro has gone me after about 8 years broken, and I had him with me often. Both listening to classical music and drum and bass making it a pleasure. Just maybe not for other people sitting around, since the model is an open. But if you like riding a bike and despite headphone ban will also feel themselves still safe is better off with open headphones because you can still hear the traffic.
I can understand the headphones in terms of size (collapsible! Very convenient!), Recommend sound quality and durability. Allen miserly people who by themselves they claim were music lovers and save on headphones (and about the totally unsatisfactory sounding Ipod headphones use) I can only say: 26 euros are a pittance for what is to get to fidelity. Conclusion: Check it out!
