I would really like testing the headphones, but the careful unpacking, I had already a part of the headphones in his hand. The folding function of the speaker is held together with a plastic clip 2 cents if it had held. Even otherwise, the processing and the processed materials of Koss is not worthy. So rather than Kotz Koss, incredible. The Koss Porta Pro is here better around classes, but just a very different part in another segment.
