Description
Versatile headphones for any activity The Koss SportaPro portable headphones offer portability, flexibility, and a headband designed to be worn either atop or behind the head. Equally well suited for use at work or on a jogging trail, the SportaPro's open, foam-covered ear cups allow for ambient environmental sounds to be heard, which can be helpful in a recreational environment. 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.

I've been using Koss PortaPro headphones for many, many years. An accident destroyed my last pair, so I decided to marginally switch things up and get these PortaSports instead. The sound quality is nearly the same, but the set is lighter, more comfortable to wear, and cheaper! The speakers themselves appear to be slightly smaller in diameter, which for me is more comfortable. Stop messing around with cheap Bluetooth wireless headphones. This $25 pair of Kosses blows them all out of the water. I've used them for music editing, general listening, working out, and listening on high-end stereo equipment and turn-tables. The quality of sound is simply unmatched for the price.

I lost most of my hearing in Vietnam in 1969. I am 86 years old and over the years I've had hearing aids provided by the military and Veteran Administration, but I now have a hard time understanding normal conversations. The VA recently ordered me a new pair of hearing aids and sent me a POCKETALKER 2.0. This is an amazing device as I can hear normal conversations and things that I have not heard in years. The only problem is the headphone is awkward and very hard to keep on. I've tried several different headphones that have good sound and are comfortable and easy to keep on. The only one that I have found that meets my needs is the KOSS SPORTA PRO. Road noise is a problem.

Sound quality: I directly compared this with the Sony MDR-ZX300AP Sound Monitoring Headphones (2x the price) and pair of Panasonic light weight headphones (1/2 the price). The Sony and this Koss had fantastic sound quality. Of the two the Koss was better, first it had greater clarity of sound and spoken word was more distinct and less muddy. Additionally this one was louder at he same volume setting. All else being equal a louder headphone indicates more money was put into the magnet and sound coupling efficiency-- hinting at the good engineering. The slightly cheaper panasonics were no match in sound quality, compactness, construction quality, though they get good marks for being the lightest (and thus highly comfortable for casual listening) ergonomics Unlike the typical modern style of headphones this one has a plain (adjustable) spring metal bar over the head. This was actually slightly more comfortable than the Sony for the simple reason it gripped my ears more firmly so the top bar did not have to sit on my head-- something I find to be very uncomfortable. Now I've have more comfortable over the ear cans with padded head bars and also even more comfortable on ear ones as well but these were quite satisfactory while being much less bulky or heavy than heavily padded cans portability The spring metal is not to make it cheap but is actually an engineering innovation. First, it's adjustable and heavy duty. This is to support the feature that when you fold this thing up you can compress then head bar. it becomes a tight coiled spring and there are two little hooks on the ear peice hinges that hold it tightly coiled. The ear peices then hinge into this folded state and the whole thing fits in a the tiniest space I've ever seen for headphones with only two hinge points. (your typical folding headphones either have more fiddly hinges to break or are novelty items with fragile plastic swivel joints that won't hold up to travel abuse in your backpack. others that use the same spring metal style are more flimsy and usualy cheap all over/) The only thing on these that looks flimsy is the foam ear coverings. They are thin, feel delicate and I expect I will tear them or they will oxidize and wear out. I see they actually sell new coverings so this is probably why. Styling Now the styling of these is definitely weird and combined with the metal head peice makes them look throwback if you set then next to a beefy Beats or Bose headphone. But I'd say the engineers defintiely triumphed here. It sounds good, it is rugged, it's compact and it's reasonably comfortable. The price is remarkably low for such quality. Conclusion: They put their money in these were it counted. They stole design styles from cheaper headphones but toughened them up and paired them with quality components. I really wasn't expecting these to be better than the Sony monitors but they were. these of course can't match the audio isolation of a quality branded over-the-ear noise canceling headphone but for $20 these are as good as you can get.

I had to hear for myself if these Koss headphones were any good. I was amazed by the sound quality, especially the bass. Great midrange. The treble is not bad, but i upped it with an equalizer to my liking. Try listening to Vivaldi's Winter with this. My only complaint is that after wearing it a while, your ears may hurt a little. When you you first wear it, it is comfortable. You can also fold these, a plus.

These are my favorite headphones

Short version: sound great, design/construction is a little awkward, surprisingly durable. Great sound for the price. Long version: First off, let me say that my review is based on a pair of SportaPros that I've had for 6 years. These bad boys sound great--far better than anything else I've tried in the same price range. Most significant, in my opinion, is that they have what many headphones seriously lack: bass, and lots of it. Some reviewers say they have too much bass, and while this may be true, it's preferable having too little. It's easy to tweak EQ settings to tame heavy low frequencies, but if your headphones can't reproduce said frequencies, no amount of tweaking is going to help. Other than the bass, things generally sound really good. They don't compare to numerous $100+ studio headphones I have used for music and audio production over the years, but again, they knock everything else in the price range (that I know of) out of the park. The design is a bit odd. These headphones can be worn with the band over the head or behind the neck. You shift between the two "modes" by rotating the earphones ninety degrees relative to the band. I find behind-the-neck mode to be extremely uncomfortable and never wear them like that, but the ability to rotate the earphones helps to compact them when carrying in a bag/suitcase/etc. They are pretty comfortable when worn in the usual over-the-head position, and the small cushions on the inside of the band keep them from irritating the sides of your head. I've definitely worn more comfortable headphones, but in this mode, these ones aren't bad. The materials look and feel pretty cheap, and I'd not have been surprised if they had fallen apart after a few years of regular use. Surprisingly enough, however, I've had them for 6 years and they are still in great shape. I'm not too rough with them, but they do spend a lot of time unprotected in my backpack. The band has bent slightly, but not enough to be problematic. I've replaced the ear pads once, after the originals had worn down enough that they had become uncomfortable to wear--they never actually tore off, as is common with cheap headphones. You can buy a set of 6 replacement pads for about $4, so this isn't a big deal. All in all, this is a great product. Excellent for the price. It focuses on sound quality over build quality, but the build quality is pretty decent too. And yes, they are pretty ugly, so take a good look at the picture and make sure it that isn't going to bother you.
