Input:
The Koss PortaPro Headphones have an amazing sound. They have high quality sound just like some of the more expensive brands. They are comfortable to wear, breathable and don't make my ears sweaty. They also fold up nicely to store them away. The case that came with these looks and feels like a leather pouch. I wish it was a little larger so that the headphones would slide in the pouch easier, other than that, I have no complaints. I highly recommend these headphones.
