The SportaPro's weight is a mere 2.2 ounces, and the headphones boast a frequency response of 15 to 25,000 Hz, delivering (on paper, at least) quite a bit more bass than most home speakers can. Impedance is 60 ohms, with less than a 0.2 percent distortion and sensitivity of 103 dB SPL (with a 1 mW signal).
The SportaPro stereophones are collapsible and come with a carrying case, as well as both 0.125-inch and 0.25-inch jacks. Koss covers the headphones with a lifetime warranty.

This review is from: Koss SportaPro Stereo Headphones (Electronics) I have to admit, I wasn't expecting much for [the price] but Ihave been thoroughly pleased with these little babies ever since I received them. Since aural satisfaction varies widely by person, I will try and give you and idea of what I look for in the phones I buy. While not a fan of super exaggerated bass, I do err on the side of slightly emphasized low down sounds, especially for phones on the go for working out, etc.. Also, I'm not looking for super high fidelity when I'm doing sit ups and biking through downtown. These headphones are light and they sound really good at high or low volumes, even with a good amount of bass. I tested them out on my current headphone killer "Fight Club". It has a lot of techno-low throb bass tracks that my Grado's, my Sharp phones that came with my Minidisc player and my Sony CD250's, start to cry about at high volumes. Try the end of track 3("What Is Fight Club?"). Although no headphone(or speaker) has ever been able to handle...Read more 35 of 36 people found the following review helpful: By Amazon Verified Purchase(What's this?) This review is from: Koss SportaPro Stereo Headphones (Electronics) I love these headphones; they've got superb sound (particularly the bass region--I didn't know headphones were capable of this kind of bass!), they're very portable, inexpensive, and the accessories & features it comes with are great. They're also very comfortable (particularly because of the foam pads that secure the phones behind/above your ears), although I have a small head and I've heard that these phones don't fit so well on bigger heads. I also like the way they look, and the lifetime warranty is a nice bonus. 51 of 55 people found the following review helpful: By Reticuli (Las Vegas) - See all my reviews This review is from: Koss SportaPro Stereo Headphones (Electronics) Strait out of the packaging I hooked them up to my HDCD Denon player. Overall, they've got good highs and mids. The 6khz treble region could be a little more pleasantly recessed than it is, but the high-end never gets fatiguing at normal volumes - only when loud. I must say that the bass is a little exaggerated. It is noticeably overdone in the 30-80HZ region -- the lowest you can pretty much hear with headphones. This never *seems* to muddle the mids, which is often a problem with bass-heavy phones. It doesn't seem excessively boomy and there are oodles of low-end dynamics, which I did not expect. They remind me a lot of the Denon 950's, but without the Denon's tissy-fit highs. When I hooked them up to my Panasonic 361C portable, I was surprised even further. With Curve: Doppelganger, the bass didn't seem even the slightest bit exaggerated. Unfortunately, when I moved over to extreme low-end intensive music like Massive Attack: Mezzanine, there was still a little too...Read more |
