In short: If you need a spare pair of 'phones or even a single pair for most situations (probably not great for exercise, however; dunno), you really can't go wrong with these.

have two pairs of these now and they work great - light, don't squash my head (mine's on the large side, too), and sound quality is excellent, outstanding for the price!

These are a cool pair of headphones to own

This is the third pair of these beauts I've owned (lost previous pairs...)

Very handy pair of headphones

Previous pair had a channel (side) finally not work so could only hear half the sound

So pay forty bucks now and have a great pair of headphones for the rest of your life.

My first pair broke at the headphone jack after 3 weeks of use

My favorite pair is now the Koss

I purchased my first pair 3 years ago, and after they recently failed, Koss honored their warranty and shipped me out what seems like an entirely new pair.

I haven't had a more comfortable pair with good sound in this price range.

The new headphones seem to be just as well made as the older pair

I've been looking for a good pair of supra-aural headphones under $50 - the problem is that circum-aural ones are too big, and normal supra-aurals hurt my ears after a while because I wear glasses and they pinch

The 1st pair, 'went a missing' (probably wrapped around my ex's head)

These sound really good for an inexpensive pair of headphones

If you're looking for an inexpensive pair of good quality headphones, these are definitely for you

and I’m obsessed with having a reliable, clear-sounding pair of headphones that plays everything well

They have very solid value for money in terms of their sound quality, but I've never had a pair last more than two years before one of the earphones loses sound

while working out (had a pair just like them for almost 7 years).

For such an inexpensive pair of headphones, I couldn't be happier

All in all, this is a true classic - if you're down with the retro look, you'll find a solid, great sounding, comfortable pair of headphones that rivals pairs twice the price.

If you're looking for an inexpensive pair of on-the-ear headphones, these are worth the little bit extra that you'd pay versus buying an el cheapo pair from a big box store.

You can wear these effortlessly for as long as you desire, and if you are so inclined, they can also serve as a great pair of headphones to fall asleep with

I didn't want to pay more than $30-40 for headphones, but these were a significant upgrade in sound from my previous (cheaper) pair.

The last pair I just bought a month ago already lost sound in one side

Not only did they not sound as good as my old pair, but they barely lasted a year with light use

A good solid pair of headphones

I bought a pair of these about 7 years ago and really liked them

Overall amazing pair of headphones especially for the price!!!

Easily my favorite pair of headphones I own right now, and I have some pricey ones

Great pair of headphones

My first pair broke but these are lifetime warranty, sent it in and got a working pair within a week or so

My wife once offered to buy me a "better pair" of headphones as a gift (she genuinely thought these were a junkyard bargain)

Overall its a very good pair of headphones for the price

Meanwhile my old, cheap pair of Sennheizers still work fine after 20 years.

Meanwhile my old, cheap pair of Sennheizers still work fine after 20 years.

but I could have put 20_30$ more and got a better pair.

These headphones are super lightweight and comfortable, easily the most comfortable pair I've ever owned

Made in Mexico (not China)You can't go wrong with it if paired to any portable device.

They fit like a good pair of gloves and the sound is superior

I recentley broke my orginal pair

You can wear these effortlessly for as long as you desire, and if you are so inclined, they can also serve as a great pair of headphones to fall asleep with

Not one pair has ever failed on me but the cord will become stiff & hard and difficult to untangle after about 12-18 months

After buying about 5 more pairs of headphones and not liking the sound of any of them, I got my 3rd set of Porta Pros and played random songs at medium volume constanly for days to break them in and have been using them for about a year now without any problems

All in all, this is a true classic - if you're down with the retro look, you'll find a solid, great sounding, comfortable pair of headphones that rivals pairs twice the price.

The best pair of headphones I have ever owned

They sit well over the head and on the ears~ Couldn't have asked for a better quality pair of headphones, especially at this price!

Sound Quality: I have a studio for a radio, very different from recording, but I rely heavily on having a flat response and a strong pair of phones.

Incredibly thin wires supporting such a good pair of phones.

while searching for an inexpensive pair I could keep at the office without being too terribly worried if they 'went for a walk'.

Incredibly thin wires supporting such a good pair of phones.

I did not buy these on a whim, and nearly bought about half a dozen other, more expensive pairs before I settled on the PortaPros

Even so, good sound can save an uncomfortable pair of phones

Fantastic pair of Headphones

They are a good pair to have if you listrn to Metal music and has good

I went from a Sennheiser HD201 to these sweet pair

Excellent pair of headphones

Secondly my pair lasted longer than any other set that I have had and when they finally broke, I sent them back to Koss with 9.00 for

Amazing, my second pair

Anyway, I wanted to get a cheaper pair of portable headphones to use at the gym,

These are a grate pair of cans and they do deliver in quality

They are not the most comfortable pair out there but that can be adjusted

Because I have a more expensive pair of over-the-ear cans, I have limited opportunities to use these, but I don't regret buying them at all.

Get past the plastic look and discover a great pair of inexpensive headphones that could cost three times as much and still be the best.

For an inexpensive pair of headphones, these KOSS produce plenty of high quality sound

I was looking for a comfortable pair of over-ear headphones to replace my last pair, and these have blown my mind

I have a pair of cheap Panasonic earbuds that have been going for YEARS with no problems, even though I frequently crumple them up, stuff them in my pockets, and toss them around haphazardly.

This is my second pair I have purchased (lost the first pair :()

For the price, these are a great-sounding pair of stylish headphones that are surprisingly well-made

They have everything you’d want in a good pair of headphones:- Clear, balanced, BEAUTIFUL sound, with excellent but not overpowering bass.- Lightweight and compact but durable.- Incredibly comfortable with lots of adjustment options.- Light on the ears so you can hear what’s going on

Now just a couple weeks ago my pair went bad.

Amazing pair of headphones for the $$$

Honestly very impressed by the size of the sound stage with their open design, I feel like I'm wearing a pair that costs hundreds more

My favorite value pair of any listening devices WAS the Sennheiser HD558

I dont know if they changed the way they are manufactured, but this new pair was super mediocre.

But overall if you're on budget for a reliable pair of headphones you can't go wrong.

This is most common with the jack that is NOT angled like the one I purchased here.- After prolonged use you start to feel the push from it on your earsTo conclude, this is a great pair of headphones to bring with you on a long flight or road trip, considering that it can easily fit into a jacket pocket or backpack

Overall, a nice pair of headphones

This is an exceptionally comfortable pair of headphones

excellent as before

cheap，I like it

The sound is great for electronic music as well as R and B/Hip Hop, and the base is impressive for these
