  • This high quality portable stereophone set performance and comfort standards for personal listening worldwide. Over the years, much to the delight of devout PortaPro enthusiasts, Koss has preserved the original design and performance that made the PortaPro a portable music icon. Today the PortaPro remains the headphone of choice for the discriminating listener.The PortaPro features dynamic elements that deliver exceptionally rich, deep bass and a remarkably wide frequency response from 15 - 25,000 Hz to capture every nuance in your favorite movie or musical performance. Constructed from mylar, the elements are extremely rigid, minimizing mechanical distortion and ensuring exceedingly accurate sound reproduction. Neodymium iron boron rare earth magnet structures enable the PortaPro to deliver greater volume so you can hear every note, even when competing against the sounds of a commuter train with a low-voltage MP3 or disc player. Oxygen free copper voice coils improve signal transmission and conduction for cleaner, clearer sound. Foam earcushions provide an open, hear-through sound that lets you keep in touch with your surroundings perfect to wear while running, at work, or while traveling. Whether you're listening at home or on the go, the PortaPro will bring the excitement of a live performance to any recording.

    "Great Value Headphones possibly the best sound on budget"
    Pros - Great sound clarity and details, lightweight, comfortable, punchy bass, lifetime warranty
    Cons - Old looking design, headband that will rip off your hair, leak sound in and out, not quality cable
    These headphones are well known for its low price and quality. I think they should be called shockers because when you look at them its one thing but when you listen to them suddenly they change to the most expansive cans you can get :)  Sounds is really impressive, something you must try. 
     
    Overall great headphones. I actually prefer the design of Sporta Pro not Porta Pro... I had both so I took speakers from Porta Pro which are better and got them into the Sporta Pro headband which looks cooler. I also put double pads on both sides so they are a lot more comfortable. These are great for travelling where you dont have much space to take them with as they fold into pretty small compact size.
     
    Koss should really reconsider to change the design of these as the headband could be done better way, they could try to make a closed version of these, replaceable cable and maybe rotating cups then they could seriously compete with HD25 from Sennheiser. The fact they do leak sound in and out makes them difficult to use outside which I find the biggest issue with these. Forgot to mention the cable quality should be improved too as it intend to break when you wearing them outside due to the hot / cold weather. This happens to all of them and I have 3 pairs.
     
    I always wanted to try some other models from Koss but haven't had the chance.

    "Still one of the better headphones below $50"
    Pros - Price, comfort, mids, upper bass
    Cons - Poor sub-bass, fluffy treble, build quality
    Sound...
     
    From 100 Hz to 3000 Hz, they trade blows with much more expensive headphones, and that is not hyperbole. That is why so many people love them.
     
    Above and below those cutoffs... no of course not.
     
    But still, the mids are crunchy and savory. The highs are smooth yet detailed enough to be enjoyable. The bass is warm but reasonably tight, and certainly not bloated. The sub bass is nonexistant, the upper treble is lo-fi. But these little bastards cleverly stylize their deficits to mask their impact on the sound. It's an enjoyable filter that you can view your music through, that isn't the highest in fidelity, but it's faithful and playful enough to be enjoyable for what it is. Don't EQ these (it'll just reveal how flawed the upper treble really is in painful detail). Just listen to them as-is, think of it as a flavoring for your music.
     
    Another thing is that just about any crappy hardware can power them. And they will take the worst onboard DACs and the most cringeworthy recording qualities and even the oldest and most unlistenable 128 kbps mp3s and they will make something tolerable out of those. They are the ideal consumer-grade headphone, basically.
     
    Comfort... is a mixed bag. The headband will make you bald if you're not careful. The hook will dig into your right ear if they're sitting wrong.
     
    Build... they're $30. What do you think?
     
    In summary... These are great starter headphones. I would strongly recommend them for students on a budget, as I was a decade ago when I first bought these. Going further with your sound requires significantly more research, time, and money. If you don't want to fall into that hole, this is a good stopping point right here. I still enjoy these guys. I've had them for 11 years. I've bought 4 during that time. Two got stolen, one broke (now I keep two at all times so I have one spare in case the other breaks). One other interesting thing is that they're easy to open up and repair. I've soldered the wires back on multiple times after snapping them with a doorknob, and they still work great. Even if you've been exposed to higher def headphones, if you listen to these for a while, their easy-going nature and crunchy, savory mids, will win your heart once again.

    "The benchmark in affordable on-ear headphones"
    Pros - They nailed it; pure enjoyment of music in a comfortable, fun-looking headphone with a killer guarantee.
    Cons - You might get mistaken as a hipster. They're not a replacement for studio monitor phones. The ear-cup foam will degrade over time.
    Market niche: To provide a high level of musical enjoyment at an affordable price.
    Obstacles: People associate cost with quality. Fashionable name brands, aesthetics, compactness, and gimmicks (noise cancellation) command a higher priority in today's market.
     
    I'm one of THOSE. You know...vinyl is superior to digital. Tube amplifiers beat solid-state. FLAC files only. Definition, soundstage, separation, muddy/boomy/punchy. No replacement for displacement...drivers, magnets, cone construction. Yup. Guilty. 
     
    But I'm going to say it; for pure portable musical enjoyment, I reach for these every time. They aren't "accurate" headphones. They look dorky. They leak sound. The foam muffles some of the frequencies.  But at the end of the day, we listen to music to FEEL something. Nostalgia. Sadness. Jubilation. Air guitar. Steering wheel drums. Head bobbing. A heart that skips a beat. Gall-darn it...the Koss Porta Pro makes you want to pull a Risky Business and run around the house in your underwear. Or cry while you wash dishes. Or daydream while you go about your daily business. Or sing along and actually hear yourself (sorry, closed-ear phones). 
     
    The Koss Porta Pro is the guilty pleasure hamburger of headphones. If I want a 5 course meal with foie gras, Filet Mignon and Lobster tails, I'll cocoon into my Audio Technica MTX-50's. If I want a spicy thai stir fry or tasty sushi, I'll borrow my daughter's Audio-Technica MTX-30's. Nevermind the Dr. Dre Beats Solo and Bose Soundtrue II and heap of Apple earbuds stashed in a drawer somewhere around here. For pure comfort food, there is only one choice: Koss Porta Pro. 
     
    Just buy them. And shave your face, unless you like being identified as a Hipster.
