I own many sets of cans. Maxell, Sony, Sennheiser, Grado, Koss, Bose, and a few more in my stereo box. I listen to the  Koss porta pros the most, because they sound best with the widest veriety of music. They have great detail in the high and midrange for clasical and accoustical, but also possess fabulous tight bass if you like R&B, hip-hop, jazz. They are almost on par with my Grado SR80's, and being 1/3 the price and more portable, they get listened to the most... Good job Koss, still going strong after all these years!
