The Koss PortaPro collapsible stereophone combines high-quality sound reproduction with a unique design for the ultimate in convenience and comfort. These over-the-head headphones have a dynamic element design for deep bass performance and a frequency response of 15 to 25,000 Hz to ensure the music comes through clear and bright.

Also designed for comfort, these headphones have two adjustable temporal-comfort zone pads to shift the pressure and perfectly balance the ear plates on your ear. The open-earphone ear plates are multipivoting and, together with the adjustable headband, allow for maximum comfort.

The PortaPros are collapsible and come with a carrying case, so it's still easy to take them with you even when you're not wearing them. A 0.25-inch adapter is included to ensure they will fit with any system.

Koss offers a lifetime warranty on its PortaPro stereophones.

Buyer's feedback: - * Fantastic performance for the price ...
As most who are considering a purchase of these headphones know, Koss has sold this model unchanged for over 20 years. The reason for this is simple - you don't mess with success. While for some the appearance may be controversial, there is an undeniable steampunk-retro appeal to the angular, stainless-steel industrial styling.

Functionally, the Koss Porta-Pro shines. The earpads can be adjusted to be as light or as tight as you prefer. The sound quality and frequency response belies the current notion that one must have in-ear buds to really enjoy crisp highs and strong bass. You will spend 100.00 or more to get better sound, period.

Where these headphones really come in handy, is environments that might have distracting background noise, but do not allow for total isolation. I like to be able to work in my office without distraction of conversations down the hall, but I do wan to hear the phone ring or my name called by nearby colleagues. The Porta-Pros fit the bill to a tee.

Highly recommended.

Buyer's feedback: - Better to sound good than to look good
The headphones are somewhat 'clunky' and they don't look as 'high tech' as some other types, but the sound quality is excellent and they are very comfortable to use. Overall, they are a very good value.

Buyer's feedback: - * maybe i got a rare bad pair.... ...
....but after about 6 weeks of having these the left side sounds like the speaker is blown. I don't really turn them up too loud so am not sure why this happened but at least i think i can return them to koss with their lifetime guarantee. I do have to include $6.00 for shipping and handling plus pay the shipping to them as well so this is not all good. That's pushing about a third more of what i already paid for these and since it was 6 weeks after i received them it was too late to return them to amazon. The sound of these is pretty good, not quite as fantastic as some reviews would have you believe, a little boomy on the bass if you like that all the better. Anyway, they're decent enough and if mine hadn't blown a speaker on one side i'd probably give them 3 and a half stars anyway....but one star off for making me shell out another almost 10 bucks due to what seems like koss' quality contol. Wish i could recommend these but after this experience i wish i had gone for the sennheisers.

Buyer's feedback: - Cool and Comfortable!
I switched from my ipod earphones to this and what a relief! Really light on your ears and you can listen to it for hours. Can't expect more for $35!

Buyer's feedback: - * Good N Cheap ...
After reading a very positive review of these headphones in Computer Shopper Magazine I decided to buy three for use in my workshops and classes.
I like their light weight, compactness, and great sound quality. Over time they may not take the abuse some of my students will subject them to. For now I am very pleased with them.
