Many have complained about the headphones being too tight, but I have a pretty big grape and have no trouble wearing these on a two hour walk.

I use these with my awesome Archos JukeBox Recorder 10, and they are a killer combo. Many MP3 players sacrifice a resonable amp for smaller size, so these Porta Pros will help salvage players with diminutive amps.

The only complaint with my Porta Pros is they are open ear, and people are always noticing my music, even though they all admit I'm not listening that loud once they try them on.


Koss PortaPro's simply rock!   June 24, 2003

I have tried at least 5 different headphones from the earbud type to the every rear mounted type. These phones have an outstanding high output volume if desired. The quality of sound reproduction is the best that I have heard in the portable class. I have some good full coverage phones and they have superior bass but that is to be expected. The first thing that people remark about while listening to them, is the realistic and profound BASS. The only thing that may be a problem is that the pads tend to cause you to sweat under extreme or hot weather exercise. With the realization that no set of headphones are ideal under all conditions I feel the vast majority of people that hear these phones will want them for their own. I have literally sold a half a dozen just by letting people listen to mine. The lifetime warranty is a bonus!


How'd they fit all that bass in there?   October 18, 2004

I wanted the best pair of portable headphones that could be had for $50 or less. All research pointed towards the Koss PortaPro and the Sennheiser PX100, each available at $40. I chose the PortaPro for its promise of greater on-ear comfort for extended listening.
The immediate first impression is that the bass is astounding for such a small and lightweight set of cans. The overall sound, once tweaked to my taste via EQ, is again remarkable for such a featherlight unit.
In short, you could spend a lot more on a pair of 'phones, but you'll not find a better combination of portability, sound quality, comfort, and value.
Highly recommended!

This is the first time I've ever written a review on anything. After listening to the Koss Porta Pro's for the first time, I felt compelled to write a review. For lack of a better word, I will just say what everyone else is saying, they are "amazing". I have been obsessed with music and sound quality my whole life. I am in my forties, so I've been doing this for awhile. I've been well known for returning things because there are very few things that really live up to my standards. Believe me, I drive my wife crazy in this area (among others). These headphones are probably the best "value" I have ever experienced in audio. I was thinking about buying the Sennheiser PX100's just to see how good they are, and to have a good pair of headphones at work as well as at home. However, I can't make myself do it. I ordered a second pair of the Porta Pro's for work. You simply can't go wrong buying these headphones. Especially if you like bass. They have very strong bass, but it isn't sloppy bass that steps all over the midranges and the highes. They are also the most comfortable headphones I've ever used. However, if you want isolation from the noise around you, these aren't for you. Take it from someone who's anal about sound: for the money, I can't imagine you doing any better.

Final word: I'm using them with an iPod and I prefer the "Electronic" EQ setting.


Only one gripe   May 5, 2006

I bought the Koss PortaPro Headphones to replace the earbuds for my MP3 player. They're light, comfortable and have decent audio capabilities. You can fold them up and put them in my pocket. I'm generally satisfied with them and would make the purchase again. My only gripe is that the earpieces tend to detach from the frame. There's only a small notch and groove holding them together. Reassembling them when the earpieces come off isn't a huge hassle, but it is annoying.
