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.

I couldn't decide between the Sennhauser PX100 and the Koss Portapro headphones. I bought both, so I could take them home and compare at my leisure. Result: They are both excellent choices! You will be pleased with either. But to distinguish between them:

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.

I'm always on the lookout for the best sounding portable phones, and these are the best I've found yet. They have the smoothest, wide-range sound I've heard from any portable headset. I'd expected that in the 13 years since I bout them, that someone would have come up with something better. However, I've yet to find anything that comes close.
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've worn out two pair of these phones in the last decade. The sound quality was great. Wonderful bass--the only phones with better have been phones that fully cover my ears--and aren't really "portable." These stayed comfortable for the excruciatingly long flights from SoCal to northern Norway, even while wearing glasses. They fold up nice and small, easy to tuck away. They also performed adequately while watching airline movies ... more than saved the price of the phones over several trips!
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.

Take what other reviewers have said about these headphones, believe them, and then multiply it by 100. I received a pair of Koss UR-20s as a gift years ago and loved them so naturally I looked to Koss again when replacing my portable/on-the-go headphones. After buying a pair of KSC-55s, which sounded great but were uncomfortable for me personally, I hopped on Amazon and found everyone raving about the PortaPros. I figured they were good, especially considering that the design seems unchanged since the 1980s (which has to mean something), but I also figured that this was one of those things that was just too good to be true. However, these are bar-none the most amazing headphones I have ever put on my head. Listening to some of my favorite songs for the first time was one of those 'wow' moments where you realize you have found something that changes your expectations completely. The bar will be raised the instant you hear the bass response and incredible acoustic qualities of these light, comfortable headphones.
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!
