I am very happy to have bought these headphones, for ages I have put up with varying degrees of discomfort when using headphones whilst wearing my glasses, but the Porta Pro has finally solved this problem. No more sore ears when watching movies on the laptop or listening to music on the go.
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.

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 magnificant 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 (£23.49 delivered!!! buy 'em quick, I've seen them for £40+ elsewhere) portable headphones that sound absolutely fantasic and feel great weather your travelling, at work or chillin' at home then look no further than the Koss Porta Pro Stereophones.

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.
