2.0 out of 5 stars Great sound quality but very poor build quality
This is an update of a previous review that I posted where I gave this product 4 stars, sadly following a number of problems I have revised my rating down a couple of stars. Starting with the positives, I must say that the sound quality is great, especially for such an affordable price. They are fairly comfortable to wear and I quite like the look of them. Sadly in my...

5.0 out of 5 stars Koss Porta Pro v Sennheiser PX100,
This review is from: Koss Porta Pro Stereo Over-Ear Headphones for iPod, iPhone, MP3 and Smartphone - Black/Silver (Electronics)Since everyone else has concentrated on the virtues of these excellent headphones, I thought it might be useful for people (who have researched) to offer the following subjective insights about the Koss Porta Pro and their main rival, the Sennheiser PX100 (which is also available from amazon at a similar price point).
I own both sets, so I would like to issue the following comments about their relative sound quality.
PX100 - These offer a very beautiful, well rounded sound. Not bass heavy, but very coherent, and thoroughly enjoyable as a listening experience. They tend to improve with 'run in', and sound terrific overall.
PortaPro - These offer better bass reproduction, but also sparkling mids and highs. They seem to produce a far richer sound overall, especially when comparing the same songs encoded in the same format (WAV) on a Cowon D2 personal media player.
In short, both these sets are excellent, but if the sole criterion is sound quality, my preference is just slightly for the Koss PortaPros. I have previously owned a pair of audiophile Sennheiser HD 595 headphones, and strongly feel that the sound quality of the Koss Porta Pro, in particular, is quite comparable.
I hope this review is useful to people who are on the fence, especially as no one else seems to have covered this comparison in their reviews.

5.0 out of 5 stars WOW!!! Amazing sound and very comfortable.,
This review is from: Koss Porta Pro Stereo Over-Ear Headphones for iPod, iPhone, MP3 and Smartphone - Black/Silver (Electronics)Finally, I have found headphones that sound great and feel comfortable. I've bought many different headphones over the past two years, trying to find a pair that don't feel uncomfortable after 30 minutes of continuous listening. Below are two recently purchased headphones I own:
Sennheiser PX200: They didn't give their full potential because they sit too light on my ear. They do sound great if you push them close to your ear though.
Sony MDR-V300: Sound good with lots of bass, but sometimes I feel like I'm listening to music through a wall and they feel uncomfortable after a 30 mins. For the cheap price they're good.
The Koss Porta Pro Stereophones are mind blowing. I really can't express enough in words how good these are and they sound even better now I've run them in. The sound is outstanding with superb clarity and bass. I personally don't think the bass is over done at all, it sounds well balanced. I mainly listen to Progressive, Uplifting, Melodic Trance, for example: Puma White - Copenhagen (Original mix) & Mike Foyle vs. Signalrunners - Love Theme Dusk. These headphones sound great with other genres too and really bring the music alive. The Porta Pro's sound magnificent when used with a computer installed with a decent sound card, but they also sound great with MP3 players. I use these with my Creative Zen Touch and they are far better than the supplied in-ear headphones.
These headphones look very retro cool and in my opinion they are very cool indeed. They are the most comfortable headphones I have ever worn (I've had them on for 3 hours and I'm feeling no ear discomfort at all) and I guess thats why the design has never changed since 1984. They look quite fragile at first but they are actually pretty sturdy.
The Porta Pro's fold to fit in a small pouch embossed with KOSS which looks rather nice along with a 6.3mm Gold Plated Adapter which is a handy extra.
Overall, If your looking for awesome quality and great value portable headphones that sound absolutely fantastic and feel great whether you're travelling, at work or chillin' at home then look no further than the Koss Porta Pro Stereophones.
★ UPDATE August 2013 ★
I've been meaning to update my review for the last few years and finally here it is.
I must have about 5 pairs of these floating around now, along with my preciously preserved KOSS Porta Pro 25th Anniversary edition set stored safely in a secret underground bomb proof safe.
I've accumulated quite a large collection of different headphones over the years and have reviewed a few here on Amazon. I no longer use the PortaPro everyday as my main home listening headphone, but use them a lot when holidaying, in particular when I'm on the beach, as the unique comfort setting helps alleviate any ear pressure and discomfort caused by sand and seawater, and also allowing me to wear sunglasses comfortably. These are not great for commuting because of their open backed design.
For home listening, I decided it was time to move up to some Sennheiser HD650's powered by a Graham Slee SOLO SRGII amp, which is quite a big jump, but they are the perfect headphone for home listening, offering superior quality sound matched with supreme comfort. Obviously, the Porta Pro can't compete with the HD650's, but they have a similar balanced neutral sound signature which I always desire in headphones. My other go-to headphones, are the well reviewed and great sounding Audio Technica ATH-M50, which I mostly use for travelling (Update Oct 2013: I'm now using the superb sounding Noontec Zoro as my portable headphone of choice, as the M50's are a little bulky for travelling).
One important omission from my original review is the eventual occurrence of rattling emitting from the drivers (know as Grattle). This is caused by hair becoming trapped in the driver, which then produces annoying rattling sounds. To fix this, you'll need to take off the ear pad, then pop off the plastic driver cover (this is quite hard to do, but be persistent, as the PortaPro are very robust) and then use a rocket blower to remove the hair, you can also use a cloth or soft brush (like a Lenspen brush) if necessary, but be careful not to damage the driver.
Even after seven years, the KOSS Porta Pro sit graciously on my headphone wall of fame and I can continue to highly recommend them for those looking for the best sounding, most comfortable and great value ultra-portable headphone money can buy.

5.0 out of 5 stars A hint of heaven. After life never sounded so good...,
This review is from: Koss Porta Pro Stereo Over-Ear Headphones for iPod, iPhone, MP3 and Smartphone - Black/Silver (Electronics)After an unfortunate incident involving my (slightly hated) Sony headphones and a surprisingly high amount of vomit, the time came last week end to order some new headphones. I don't believe in buying anything without researching carefully, so after reading many reviews on all sorts of headphones, ranging from the good, the bad and the ugly, I concluded that my hard earned money (well I'm a student, but baby sitting is still work) should be well invested in a set of Koss PortaPros.
One week after ownership, and I can't think of a better way to spent my money.
Build and appearance: 7.5/10
In terms of build and design, I found the headphones much more impressive in the metal (and plastic) than I had been expecting. Quality is something I am pretty anal about, but these are pretty bang on the money. The finish is not luxurious, but feels like it will last if treated nicely. The metal is nice, and again aids the feel of durability. I had better explain - these are not by any means going to rival a JCB in terms of ruggedness. The phones are slim in design, and extremely light. However, they feel as though they will happily last a lifetime of normal, relatively careful use, while in the event of trouble you have the included Lifetime Warranty to fall onto.
The design, which I was not keen on in the pictures on the internet, looks much better on person. The headphones remain on the 'ugly' end of the scale, but in an almost endearing way. They are very unique, much due to their 80's heritage. The metal is tastefully applied, and allows for an attractive contrast against the black plastic while installing a quality look, meanwhile the blue accents (which I hated on photos) add a little uniqueness to the design, and helps make them stand out. I prefer them to black, although I think red might have looked better. Anyhow, the overall look is uniquely retro, fairly subtle, and not really any less stylish than any other set of headphones. Just more stand-out.
I hate giving perfect ratings. In my book, there is no such thing as perfection; the best can always be better. The PortaPros, however, seem to be an exception. While the much discussed "Comfort Zone" seems to be a little bit of a gimmick in my opinion, it shows the attention to detail taken in terms of comfort. The "Comfort Zone" system is designed so that the user can select the amount of pressure on the ears - firm, medium, or soft. Any is extremely comfortable, putting little pressure on the ears themselves thanks to extra pads which share pressure with the temples, while providing enough grip to hold the phones securely even during mountain biking. I personally prefer the firm setting, although the reason for this is not known. It just feels right for me.
The headphones are easily adjustable, thanks to two small plastic tabs on the head band which move back and forth to change the size of the headphones. Although other users have reported pain caused by their hair getting trapped in the mechanism, neither me, my Sister, my Mum, or my Dad have experienced this. Instead, we have all found the headband comfortable, easy to adjust and devoid of unwanted side effects (such as trapped hair). One little note - the headband does not lock, so after removing the headphones you will need to readjust the band. Once on though, the size will not change.
To conclude, I have worn the headphones for over four hours straight, and had no problems with my ears afterwards. Same with biking - I have worn the headphones over rough terrain for a couple of hours, and they did not move or cause pain. In fact, they seem therapeutic - like an ear massage :)
Sound - 9/10
This is why I bought these headphones. Firstly, I will say that I listen to a wide variety of music. This is inclusive of rock, country, R&B, pop, electronic and whatever comes in between. I have also used the headphones to watch films. A few examples of the songs I have tested these headphones with:
- Johnny Cash: Country Boy, Ring of Fire, I Walk the Line, and more.
- Blondie: Call me, Atomic, and more.
- The Mavericks: Dance the night away (very challenging)
- The Killers: When you were young
- Shakira: I'll stand by you, Whenever, Wherever, She Wolf
- Lady Gaga: Bad Romance
- Lee Ann Womack: I hope you dance
- Journey: Don't stop believing
- Cascada: Evacuate the dance floor, Every time we touch
- Many more, inclusive of Beyonce, Bullet for my Valentine, Michael Jackson, Guns 'n Roses, Gianna Naninni, Dolly Parton, Rihanna and more. If you need more information, just ask.
To summarise briefly, I have never heard any other headphones in this price range perform this well on any of these songs. I have used Samsung PX100s, PX200s, various Sonys, several Grados (including the iGrados at a not too dissimilar price and numerous other phones. At this price, these are the best.
Bass is strong, but detailed. Johnny Cash, The Killers, Guns 'n Roses are just some of my artists which use significant bass, and this is utilised very nicely by these headphones. The bass is strong and detailed enough to please those who thrive off it, but eases off to allow sufficient detail throughout the mids and highs. Despite other reviews, it was not the bass that caused these headphones to win me over. It's how brilliantly they combine the bass with the competent, strong, and detailed mids and highs to deliver a sound that captures the mood and detail of the song as it was intended. I haven't yet tried any other headphones in this price bracket that achieved this. They sound brilliant, like headphones that cost at least £75. The highs sing sonorously - beautifully, with powerful emotive mids surrounding them and the vast throb of bass always laying in wait beneath the other sounds. Each song has its own unique feeling, and each instrument in each song makes its own unique sound heard. I don't what else to say, except that this remains true for all genres of music. If you wan't sound and cash in your pocket, buy these. Now.
The headphones are tiny, particularly for the excellent sound they deliver. Even better, they fold up - in a simple, self explanatory way - so that they are tiny enough to fit into the included leather bag. As said, they feel durable enough for everyday use, while their high comfort and strong grip means they can be used in almost any situation for many hours on end.
This sounds like it should be a perfect score yet again so far, right? Wrong. I knew this prior to purchasing, but these headphones leak sound like OK! leaks gossip. It's that bad. Honestly. One of the reasons I bought these headphones was for flights, however I would probably be so conscious of the sound that I would be forced to turn them down. In which case, I would suffer from the poor isolation and quickly turn them back up. To hell with society. I want my music.
Despite this, I think that their small size and ease of use makes them practical for everyday use. Just be prepared for stares.
These headphones come with everything you could expect for the price.A leatherette case, a headphone adaptor for planes, a headphone adaptor for your guitar amplifier, and an all important lifetime warranty put these headphones at the front of their rivals.
Buy these headphones, and you will not be disappointed. The sound is excellent for the price (at the top of their class), the design and build is as you'd expect, they're as comfortable as a hot bath, and they're small enough to be practical. Top the icing with a lifetime guarantee and good accessories bundled, and Koss have a product that I think could be celebrating its 50th birthday and still be heading the pack.

5.0 out of 5 stars Perfect for glasses wearers.,
The sound quality is exceptional, they are a massive improvement on the Sony-Ericsson buds that came with my w810i mobile phone (which are, incidentally, the best of any earphones packaged with a portable music player), and I also prefer the Porta Pro to my Sennheiser HD202s; they easily handle the most bass-heavy of tunes -I listen to a lot of dubstep, and it doesn't get any bassier than that - and the sound quality remains consistently high across the frequency range.
In this price range, there are few other headphones that can compete with the Porta Pros for sound quality, but for me the main attraction of these phones is the comfort factor. The Comfort Zone pads rest above the ear and they do a great job of dissipating the pressure on the ears. I can't stress highly enough how much I appreciate being able to wear these for a few hours at a time, whilst wearing my glasses, without any of the discomfort I usually experience with other headphones.
When you throw in the lifetime guarantee from Koss, and the fact that they look nicely retro, you have a great buy. I recommend them without hesitation.

5.0 out of 5 stars So Much better than they deserve to be!,
If I had any criticisms, they would be:-
- Not too strong with the treble/higher frequencies - but then I don't believe the design has changed much since the 80's when tape didn't have such a high frequency range.
- If adjusting the headband after placing these on your head, you can get your hair caught which hurts a bit.
After reading other reviews I became paranoid that I may have a fake pair. After researching some 'how to spot the difference' guides online I became a little more worried - Whilst at the same time thinking "if mine are fake, and sound this good then how amazing would real ones sound".
Beware of this guide as one point in particular is incorrect. Most guides will tell you that if you don't have a small number 1 moulded (e.g. if you have any other number like 4) in the plastic on the inside of the ear strut then your headphones are fake. The rest of the points in this guide are correct. But it also pays to bear in mind that the reviewer comparing the real and fake would probably have only 1 pair of each, so would make generalisations. My point is, that there are differences in this small moulded number - even in authentic pairs.
As it turns out Koss themselves have verified that I have an authentic pair after I sent them some photos (despite having a small number 4 moulded into the plastic). They were really helpful and got back to me really quickly. If you are worried about yours they can be contacted by online chat and then they will supply an e-mail to which you can send pics. They will ask for close ups of the foam pads (both parts) and the silver on the outside of the speaker with the printed text, they will also need a well lit up close view of the inside of the black plastic struts.
Hope this helps folks. Happy listening.

4.0 out of 5 stars Amazing sound, but beware of counterfeits (second party sellers)!,
What's so great about them, is the fact they are so tiny, but produce a very big, full sound. I showed them to a mate, and he said 'did you get those from the pound shop'? And then he tried them on, he was truly amazed. It really is hard to believe that a pair of phones with a delightfully tacky, 80s retro feel, sound like phones in the upper mid range market, for 17 quid!
If your looking for amazing sound at a cheap price, you really look need look no further. The lightness of them makes you feel that you weren't even wearing them. The bargain bin basement look adds to it's charm, considering how great they sound.
But there's one minor flaw. If you have a shaved head, the plastic adjustments can be a little bothersome as they dig slightly into your head, but most of the time, it's barely noticeable (except for prolonged periods, but you can always readjust them to make them more comfy). I just wish I had more hair instead of the Vin Diesel look, then I wouldn't have this problem!
Also, when you have the switches on light mode, like I do, and you take them off, you have to readjust them to fit on your head again, because of the strange unique design. This means they will always give a different when every time you put them on.
I don't understand when people complain about how easily they break, I've had mine over a year, take them off, wrap them around, stick them in the draw, and never had any problems.
Honestly, for £17-18, you really cannot complain when the sound is this good (unless they're defective or you get unlucky and step on them).
I ordered a second pair as back up, in case anything goes wrong with these and for other purposes, seeing as they are so cheap and of great value.
But guess what, they were COUNTERFEIT!
Why? Well it turns out because it was by the second party seller STRONG HOLS. (Just look at the seller feedback, at least 4 other sellers have said the same thing), and thanks to me, and another buyer below, they have since been stopped, and no longer sell anything.
I see there is yet ANOTHER second party seller selling these. Hmmmm. To anyone reading, buy from Amazon direct, just to be on the safe side....
But if you buy directly from the second party, and they turn out to be ok, then fine.
Now, onto the 'fakes':
The switches from firm to light didn't work, it didn't come in the packaging that states 'suitable for iphones' (as shown in one of the pictures), the sound was nowhere near as good as my other pair (these don't really need burn in, they sound great out the box) and the foam pads were of a darker colour than my originals and slightly larger than they are supposed to be. Also, the 'comfort zone' sticker on each side looks to have been glued on or stuck on by sticky tape, not to mention the sliding the metal band was a lot stiffer. This is a real shame, I'd really like to order another pair because they are such a bargain (the new ones were sent back) so make sure you do your research if they don't look or sound right.
These phones create a really big sound, but the build of them are VERY easy to replicate. I guess it's because it's made of bits of plastic, foam, and cheap steel (hence the low price, you pay for the sound, not looks).
Such a disappointment. I'd expect this kind of thing on ebay, not on amazon. I just hope the genuine pair haven't been replaced by the counterfeit ones in nearly all stores (as I bought the proper ones in the summer).

4.0 out of 5 stars Koss Porta Pro? more like Koss Porta Awesome.,
Now for the sound. Well, what can I say? You can get lost in the music that these phones pump out. They can handle the rich undertones and high climaxes of classical music, the gritty distortion and anger that punk demands, the smooth stylings of jazz, and everything in between. The first artist I listened to with these headphones was Buddy Holly, and let me tell you sir/madam, they don't take any prisoners. I am, as I write, listening to the Sopranos' take on 'Woke up This Morning' by the Alabama Three (a very bass heavy song might i add, at the risk of insulting anyone's musical knowledge), and it's singing like a well fed canary.
My dear friend, at the price that is asked for these headphones, you have no excuse but to at least consider.

2.0 out of 5 stars Great sound quality but very poor build quality,
Nevertheless, despite my checkered experience with the product I decided to purchase a third set a few months ago (around August 2010), as I was dubious of the chances of finding a different brand of heaphones at a similar price with comparable sound quality (it really is that good), and I was willing to risk another negative experience seeing as they are so affordable. As of yet they haven't broken down, but I have another complaint. This time round I've noticed a repetitive clicking in the left headphone that I think is emanating from where the wire joins the headphone. This is only present while walking but is pretty annoying.
Therefore, having been the owner of three separate sets I feel pretty qualified to give a reliable verdict on the Koss PortaPros. I went for 2 stars as I still use my latest set and appreciate the sound quality, knocking off 3 stars for what I see as serious flaws in the build quality of the sets I have owned. However, I have to admit that I seem to be in the minority in having experience problems with this product, as the vast majority of customer reviews appear to be glowing. Perhaps I have been unlucky and ended up with a couple of freak duds, or maybe I'M the problem!

3.0 out of 5 stars A sadistic pair.,
1)The sound leak from this is considerable enough that the secondary listener can accurately pinpoint the genre of music you are listening to, this is not so big of a deal as...
2)After about 30 mins of listening, while still delivering pleasing sound,the pressure from the stereophones on my ears begins to cause me a lot of pain from both sides to the extent that I can't be bothered to listen any longer (note: this also occurs on the "light" comfortzone setting).
Overall, this tends to be fatiguing but considering all the 5 star reviews, perhaps not everyone will have the same experience as me.
P.S.:For the price I think the build quality and overall functional styling is very good.
