I had a pair of Koss portaPro's for about 2 years and 10 days ago the plug went bad on them. So I wrote a note about what was wrong with them and a check for 6.00 for return shipping and to ship them to Koss cost me 4.00. This is just the headphones with nothing else like the wrapper.

They have a great deep bass and nice clarity. Koss had never been very good about advertising their lifetime warranty, so I bought another Pro/4AA from Radio Shack - exactly like the original after about 20 years. Still have them. They work well when listening to stuff from the computer in the wee hours. This is somewhere where we felt the Koss KTXPRO1 did justice. The signature Koss Titanium Drivers ensure that the users get a rich yet comfortable sound output from the headphones. The sound isn’t anything out of the world but clear and crisp enough for you to be happy. There’s a right balance between the highs, mids and lows but the sound
