Product Description

Koss introduced the PortaPro headphone back in 1984, and they've been a hit ever since. To this day, they still deliver excellent sound quality, particularly for phones in this price range.

Phones are collapsible, for maximum portability.

Get just the right amount of pressure.

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.

Koss offers a lifetime warranty on its PortaPro stereophones.

Specs

• Frequency Response: 15-25,000 Hz

4.0 out of 5 stars Koss Portapro vs Sennhauser PX100 October 16, 2005

By Peth

I couldn't decide between the Sennhauser PX100 and the Koss Portapro headphones. I bought both, so I could take them home and compare at my leisure. Result: They are both excellent choices! You will be pleased with either. But to distinguish between them:

The PX100 are more comfortable because of the foam cushions which rest on the top of your head. The Portapro are also comfortable, but I do notice the metal band on the top of my head, which sometimes pulls some strands of hair out.

The PX100 look better when on. The Portapro look kinda dorky -- especially at first -- but they are easy to get used to.

The PX100 are also more durable. Once you get the hang of it, it's quite easy to collapse the headphones and put them in their plastic carrying case. They are not going to get squished while they're in that! The Portapro can be collapsed into a ball, but if I'm not really careful, they spring open all when I touch them. It's also very difficult to get the Portapro headphones and cord into the accompanying bag.

The Portapro headphones have more bass, and to my ears, the music sounds more alive than with the PX100. The PX100 sound really good, but the Portapro sound just a tad bit better.

The Portapro feel more comfortable when under a wool hat (important for my winter walks with the dog).

Both leak sound -- there's no difference there. If that's a huge concern for you, then you might want a closed system for your headphones.

In the end, I couldn't which I liked better and kept both, rationalizing that my husband needs a pair of headphones too. Both are used regularly, although I take only the PX100 when I travel because I think it'd be much easy to accidentally break the Portapro.

5.0 out of 5 stars Best portable phones I've found in 13 years December 5, 1999

By Michael Maffie

I'm always on the lookout for the best sounding portable phones, and these are the best I've found yet. They have the smoothest, wide-range sound I've heard from any portable headset. I'd expected that in the 13 years since I bout them, that someone would have come up with something better. However, I've yet to find anything that comes close.

These phones may sound a little bass-heavy to some, but this unit has temple-pads that lift the elements away from your ears. This not only improves comfort, but also attenuates the bass, leading to a nice mix of comfort and sound quality.

Also, since I tend to be a bit rough on phones, the lifetime warranty has come in handy a few times.

5.0 out of 5 stars Great for Travel May 13, 2001

By Elderbear VINE™ VOICE

I've worn out two pair of these phones in the last decade. The sound quality was great. Wonderful bass--the only phones with better have been phones that fully cover my ears--and aren't really "portable." These stayed comfortable for the excruciatingly long flights from SoCal to northern Norway, even while wearing glasses. They fold up nice and small, easy to tuck away. They also performed adequately while watching airline movies ... more than saved the price of the phones over several trips!

I have two complaints: 1) hair easily penetrates the "speaker grill" and makes irritating noise against the actual speaker membrane. 2) The speaker, while reproducing sound well, can develop tears in the membrane easily. BE CAREFUL! Nothing is more annoying than a buzzing speaker at 33,000 feet (well, perhaps sudden cabin depressurization ...)!

My second pair wore out about the same time as my vintage walkman. I replaced the setup with a Nomad II MG & a pair of noise cancelling headphones--they make a _huge_ difference!

Five stars for sound quality. Five stars for comfort. Five stars for portability. Five stars for durability. If you're not going to spring for noise cancellation and you need a folding pair of phones, then get a pair of PortaPros.
