Koss introduced the PortaPro headphone back in 1984, and they've been a hit ever since. To this day, they still deliver excellent sound quality, particularly for phones in this price range.
The Koss PortaPro collapsible stereophone combines high-quality sound reproduction with a unique design for the ultimate in convenience and comfort. These over-the-head headphones have a dynamic element design for deep bass performance and a frequency response of 15 to 25,000 Hz to ensure the music comes through clear and bright.
Also designed for comfort, these headphones have two adjustable temporal-comfort zone pads to shift the pressure and perfectly balance the ear plates on your ear. The open-earphone ear plates are multipivoting and, together with the adjustable headband, allow for maximum comfort.
The PortaPros are collapsible and come with a carrying case, so it's still easy to take them with you even when you're not wearing them.
Koss offers a lifetime warranty on its PortaPro stereophones.
- Frequency Response: 15-25,000 Hz
- Impedance: 60 ohms
- Sensitivity: 101 dB SPL
- Cord: Straight, Dual Entry, 4 feet

The PX100 are more comfortable because of the foam cushions which rest on the top of your head. The Portapro are also comfortable, but I do notice the metal band on the top of my head, which sometimes pulls some strands of hair out.
The PX100 look better when on. The Portapro look kinda dorky -- especially at first -- but they are easy to get used to.
The PX100 are also more durable. Once you get the hang of it, it's quite easy to collapse the headphones and put them in their plastic carrying case. They are not going to get squished while they're in that! The Portapro can be collapsed into a ball, but if I'm not really careful, they spring open all when I touch them. It's also very difficult to get the Portapro headphones and cord into the accompanying bag.
The Portapro headphones have more bass, and to my ears, the music sounds more alive than with the PX100. The PX100 sound really good, but the Portapro sound just a tad bit better.
The Portapro feel more comfortable when under a wool hat (important for my winter walks with the dog).
Both leak sound -- there's no difference there. If that's a huge concern for you, then you might want a closed system for your headphones.
In the end, I couldn't which I liked better and kept both, rationalizing that my husband needs a pair of headphones too. Both are used regularly, although I take only the PX100 when I travel because I think it'd be much easy to accidentally break the Portapro.
These phones may sound a little bass-heavy to some, but this unit has temple-pads that lift the elements away from your ears. This not only improves comfort, but also attenuates the bass, leading to a nice mix of comfort and sound quality.
Also, since I tend to be a bit rough on phones, the lifetime warranty has come in handy a few times.
I don't know what I'm impressed with the most: the amazing bass, the excellent stereo division, or how loud they can get! These things are just as amazing as most of the reviews show them to be and then a lot more... I was worried about the eighties styling, but in person they don't look bad at all. I hate headphones that scream for attention, but these don't look like that when you have them on and I have already been wearing them in public (something I didn't think I would do after only seeing the picture of them online). And even if they're a bit outdated in appearance, the design is so functional you won't even give looks a second thought after you put them on.
One thing is for sure: these things have plenty of bass! Not too much (not "boomy"), but they seem properly tuned for listening to things without "bass booster" turned on, which I like. Even with the bass settings adjusted high, the bass remains clear and crisp. I'm not sure how much power these can handle without damaging them, but I listen to them very loud and they do not sound distorted or stressed at all. After a few days my left speaker began making some weird noises and it ended up being a hair stuck inside the headphones that I cleared out with canned air. Something important to consider is that these are very open and airy headphones and the treble carries very well outside the headphones (so someone nearby could definitely hear what you're listening to if you have the volume up loud).
Others have mentioned that they felt the headphones were too tight feeling, but I have a very large head and they fit me without a problem. However, if I will be wearing them for an extended period of time I always set them to the "Light" setting on the comfortZone control (which divides the side pressure of the headphones with your temples rather than just on your ears).
I already had headphones I was pleased with (Sony MDR-G52s and Koss UR-20s) but I wanted a set of small, portable headphones for use with my laptop and these are perfect. The folding design isn't something I necessarily wanted, but it is nice. The carrying case they come with (a leatherette bag) is a slightly tight fit and I probably won't end up using it much since it is not a hard case that would protect them from shock or crushing. Some others have mentioned that they feel delicate or are easily broken, but compared to other small headphones I have had they seem very well built and equally strong considering their light weight.
While I wouldn't say these are bad things about the PortaPros, it is worth mentioning that the headband is metal and will occasionally snag a hair as you adjust it on your head, and that they don't fold down as small as you might think they would so don't expect to put them in your pants pocket or something. Considering these are the worst things I can come up with to say about the PortaPros, they are nearly perfect in my book.
I can't say enough good things about these PortaPros! They're simply amazing. These are the first headphones (or speakers) I've had that sound absolutely awesome without adjusting the equalizer or pumping up the bass. They sound good on everything from R&B to Country and everything in-between. I've been especially impressed that they pull the bass and highs out of a song without getting that shrill, tinny treble that plagues so many headphones. If there ever was a question about the quality of Koss stereophones in my mind, these PortaPros have put it to rest and made me into a lifetime customer! If you're like me you'll wish you had discovered these legendary headphones (haha! how often is that said?) years ago...
I have two complaints: 1) hair easily penetrates the "speaker grill" and makes irritating noise against the actual speaker membrane. 2) The speaker, while reproducing sound well, can develop tears in the membrane easily. BE CAREFUL! Nothing is more annoying than a buzzing speaker at 33,000 feet (well, perhaps sudden cabin depressurization ...)!
My second pair wore out about the same time as my vintage walkman. I replaced the setup with a Nomad II MG & a pair of noise cancelling headphones--they make a _huge_ difference!
Five stars for sound quality. Five stars for comfort. Five stars for portability. Five stars for durability. If you're not going to spring for noise cancellation and you need a folding pair of phones, then get a pair of PortaPros.
