Summary:
Everything I could say has already been said. One piece of information is noticeably absent however, the fact that Koss has a lifetime warranty on these bad boys. If for any reason they break or fail during normal listening (i.e. anything that isn't you stepping on them) Koss will replace them for the cost of shipping (6 bucks) for as long as you own them.

Summary:
I see now why these phones have such a cult following.

They are thoughtfully designed and sound fantastic. Plus that retro 80s look is just so cool. They offer excellent clarity and a rich - though not totally THUMPING - bass response.

People get real excited and out of control about these because they're a damn good product. But let me give it to you straight. Best value in it's segment. I mean you wouldn't buy these to replace a $300 pair of Sennheiser cans. But as far as I can tell you simply won't find a better pair of phones for less than $50.

Highs: Clear and not to sharp though ever so slightly hissy at low sample rates.
Mids: Present and strong. Strong like English breakfast tea, not like Starbucks bold.
Bass: The bass is very respectable for the size. They won't send shockwaves through your heart like a nice set of JL subs, but they stand up to the spectrum and with the highs and lows create a rich listening experience.

Only major con I've found is the same everyone else has: hair getting caught in the adjustment bar. But it's not a big deal. Also, I listen to a wide variety of music but I've found electronic styles sound best on these. They fold up real neat into that little pouch too. I'm an avid laptopper, so they go right in the Timbuk2.

For under $50, simply put, PortaPros are the balls.

Summary:
One of the best head-phones I have used. They are very comfortable-you can wear them for hours and hours!! They are cheap-I got them for $37. The best part-they sound great. G R E A T. The vocals sound good, the bass is controlled-it does not get distorted at the end, other instruments sound clear and do not cram each other. It is a real joy to listen to them or, technically, via them. The sound is not distorted at higher levels so you can crank up the volume but wouldn't find any distortions. Overall you get this 'punch', this richness. I would seriously recommend them to both the enthusiasts and the casual users. Audiophiles? They are above my grade and I'm not sure whether they would like it or not but frankly I can't think of anything that they can dislike. They are one of the best products that I've ever purchased!!

Summary:
I've got a Cowon D2 a few weeks ago and decided to get better headphones than my Sony MDR-G52... (which are pretty good... I've tried a few other models in the last ten years or so and never found one that match this one!)

So I did my research... ended up having to chose between the Koss PortaPro and the Grado SR-60... Since for some unknown reasons, Grado wouldn't allow US vendors to ship to Canada (where I live), I had to go for the Koss PortaPro.

Unfortunately, I'm really not impress with the sound. Not at all. Actually, except for the bass, my old MDR-G52 sounds better than the Portapro. (So I've ordered two more MDR-G52 from ebay yesterday... as my second pair lost the ear cushions... they are very fragile and dont last very long...)

If I compare the same song being played in the MDR-G52 and the PortaPro, the midrange frequencies on the PortaPro are really lacking definition. Trying to fine tune the equalizer on my Cowon D2 helps the midrange frequencies level but it doesn't add definition.

I'm already back to my good old MDR-G52 (the model that is held by the top of your ears) with the band that goes behind the neck. A bit shy on the bass but doesnt lack any definition... and my Cowon D2 has a few goodies that improves bass without adding too much audible distorsion...

Strengths:
Not sure?!

Weaknesses:
Midrange frequencies are lacking definition... and intensity! I think I have a real pair of PortaPro but considering all the reviews I've read, I'm wondering if what I have is not some cheap black market imitation of the real PortaPro?! No way for me to know.

MDR-G52... pretty old model but does the job better than most other models launched after this one!

Summary:
I've had these headphones for 3 years, and they are an absolutely addicting sound. You know its not necessarily that they give you a kicking bass -- which they do, or a particular rich sound, rather that you can wear them for hours and your ears don't get tired nor sick of the sound. The best way to describe the sound of these headphones is warm. Very very warm. In fact like real warmth, they tend to be best enjoyed after being outside in cold weather. I come home and stick these on in my warm house and it gives me a really good feeling.

The other reviews have covered this as well, but there is something special about the bass. I once had this song which had a really punching bass for the first 20 seconds, and it literally felt like your ears were being plucked. Unfortunately I forgot that song, nor was the rest of the song particularly good.

ONE LAST THING, I have to mention that mine have sprung wire problems twice. Each time I used a soldering iron to cut down the wire a bit and resolder. First time was on the headphone end -- I gotta give the headphones credit for having a nice big user-friendly panel under which there is enough room for even a big solder iron to do its job effectively. Most headphones can't be opened and resoldered at the headphone end. Then the wire tore at the end of the socket. Anyway suffice to say, the cord is not bombproof and you might have to solder it, or take it to an electrician sometime or another.

Strengths:
EXCELLENT Sound
Good for long listening sessions -- you don't get sick of the sound
User-friendly repair of wire at the heaphone end.
Comfortable

Weaknesses:
Wires do brake once in a while -- but unless you want a much thicker wire than thats just the way it goes. At least it can be repaired.
