Returning to the 80s, the Koss Portapro headphones provides stellar sound quality with a unique design and appeal. Aside from the appeal of the design, it has a great deal of functionality. It works for every type of phone or electronic one could think of as well. Koss hit a home run with the PortaPros. Love or hate the design, there's no denying the sound quality here: they're the ideal companion for mobile audiophiles and home theater enthusiasts. Sound Quality It contains excellent sound quality with a few bits of music fading away, but it doesn't stray from the overall experience. It immerses in your music, making you feel as if you are in a world of your own. What incredible sound these headphones possess... Comfort It is not the most comforting type of headphones with hard, cold metal usually sending shivers down one's spine. It does contain, however, some incredibly soft cushions for one's ears. Design I absolutely hated the design of the headphones which immediately had provided me with an unfamiliar feel to wearing headphones. Along with this problem, it has a terribly placed collapsible band that continually got my hair stuck. My opinion aside, I could imagine how someone could enjoy this headphone's unique design, but alas I did not provide it the same love as others. Durability It will last a long time if you can take good care of it, but it will not survive if it is constantly damaged.
