These headphones are really worth the money. I have found for all complaints about fakes here in the reviews, buy my PortaPro directly at Amazon.com, and after a thorough review that I was to be expected a original goods have received. Once unpacked, falls to the low weight, without, however, to look cheap. The processing of the Koss Porta Pro's is really good and looks quite solid. The design is a matter of taste. I can say that I find it very very well done and it just this retro charm. Simply look cool when worn. In addition, they do not press The effective cushioning and the comfort zone of the ears or in the head and you can adjust the pressure additionally manually. After a time you realize no longer at that one ever wearing a headset. The Porta Pro sits firmly on the head, so you can take him sometimes with the sport (jogging or at the gym, for example).
But now to the sound. The Koss Porta Pro has really blew me away at the first hearing test !!! Such a small headset I would never have expected such a sound volume, such intense deep bass and clean mid / high in life. For this price, this really is unquestionably good. The strength level is enormous. Ifs already hurts in the ears it sounds still very good without distorting or scratching. It's really a pleasure to really experience with this headphone his favorite songs "new".
I highly recommend this headset fully and am just really excited about this miracle of sound. 5 stars!!!
