Review on 🎧 Koss Porta Pro On-Ear Headphones: Stylish Black/Silver Design with Convenient Case by Adam Krueger

I love PortaPros but the last 2 pairs I've ordered from Revain don't live up to the previous pairs I've had. The latter pairs appear to have been manufactured differently; You have problems with plastic tabs sliding on a metal band, popping and making indistinct sounds, and also with a plastic lid where the screw was on the left. I initially assumed it was a change in the manufacturing process until I received a pair of recent special edition Koss PortaPros that were identical in every way to my previous pairs except for the color scheme. So either the overall colors are generated differently or the headphones I received are not authentic. I will say that these headphones are usable, although the pairs I received fell short of my expectations with several pairs. My rating of previous headphones would have been 5 stars, unfortunately the latest pairs I have received do not deserve the same rating. I've included photos comparing the build quality of the previous pair I own to what I got from Revain. You'll notice the differences in the molds used to mold the headphone parts. They cover some issues, but it's hard to explain what seemingly tight manufacturing tolerances and warped plastic feel like.
