Twenty-eight years after their debut, the Koss Porta Pro over-ear headphones finally get a push into the 21st century with the Porta Pro KTC, a new model sporting a three-button remote control for navigating tracks on iOS and (some) Android devices.
Porta purists will be happy to hear that the skin and guts of the headphones haven't changed aside from the addition of the remote. The earcups are still secured to your head by a thin steel headband that adjusts with two sliders that tighten and loosen the tension--Koss calls this the "Comfort Zone."
The Porta Pros continue to earn a spot on CNET's Best 5 headphones list partly for their throwback design, and partly because these cans continue offering worthy sonic competition to modern headphones, even after 28 years.
According to Koss, "neodymium iron boron rare-earth magnet structures" handle output in a 15-25,000Hz frequency range. That first part sounds like marketing fluff, but having used these as my personal pair for the last three years, I'm confident marking these as the headphones to beat in the sub-$50 category.
Another Porta plus?. No need to include the original receipt, nor do you have to wait for an RMA.
In fact, Koss actually encourages customers to visit its Milwaukee location to make an exchange, if it's convenient--if not, all they ask is that you include $9 in the box to cover the return shipping fees.
Koss will begin selling the Porta Pro KTC headphones this spring for the same $50 price as the original set. While you're waiting, check out our.
