Cheap, but Beautiful Sound
I will start this by saying Iâm not an audiophile (I have/had ath m50x, beats solos, AirPods, and other basic audio products). After browsing the webs, this seemed like an excellent place to start. If you donât wanna read this whole review (tl;dr) : these are worth every penny.Comfort: 3.5/5 initially, these felt weird. They arenât cozy by any means like other headphones due to the metal headband and being on-ear. Theyâre insanely light, so it can feel like they arenât there after a while (a good thing). The on-ear aspect really is a love or hate thing. They do make it so ur ears will not feel hot, so that is a plus.Note: The comfort becomes a 4 with Yaxi pads. Theyâre larger and softer than stock pads.Quality: 2/5 there had to be a sacrifice somewhere. The build is garbage. Letâs be honest: you canât have it all at this price range. I appreciate the retro look of these, but there are issues:- headband is a thin metal that can tear ur hair out (use tape)- the âcomfort zoneâ driver casing is very cheap plastic and feels flimsy- the cable is similar to that of $8 earbuds u buy from a pharmacy store.Sound: 4.5/5 (for price, 7/5)Man, oh mannnnnn. This is where it hits you. Youll say, âoh. Thatâs why people say to get these.âSonically, these can sound better than headphones in the 100+ dollar range.Vs AirPods: Theyâre better than AirPods for sound. Not going to compare features bc no duh AirPods win, but sound wise, theyâre better in every way.Vs Beats Solos: I have the cheap solos, so itâs not the new pros, but these are better sounding. More clarity and soundstage, maybe not as much bass (barely).Vs ATH M50x: this is where the fun begins.Detail: Almost as good detail as the m50x, but I actually enjoyed these more for listening to more neutral music vs the m50x (not saying much, since m50s are very V shaped).Soundstage: The soundstage may be even better than my m50x with the Yaxis on. They WILL leak sound, though, so if you canât afford that, m50x is better.Bass: It doesnât rattle your soul, but it isnât weak either. M50x beats it in this category, which Iâm not surprised by. The drivers are so much smaller.Noise isolation: These do not isolate noise. Theyâre on-ear, so that isnât surprising. If you need noise cancellation, these arenât the way to go.Conclusion:Get these!! Try em out. I got em for $20 so it wasnât a huge investment, and Iâve heard they get this cheap pretty often.Thereâs a reason Koss still makes these. Theyâre light, look cool, and sound amazing for their price.P.S. GET YAXI PADS. They add soundstage and comfortability as well as style to these headphones. I grabbed yellow for an extra retro vibe, but thereâs a bunch of colors to choose from.I grabbed a E10K off of eBay, so I might update to see how that affects the sound as well!

Great budget sound
These things punch WAY above their price point; there’s a reason they’ve been unchanged since their design in 1984.The Comfort:These headphones are smaller than you might think. They are very light, compact, and are easy to wear for extended periods of time. Very light on the head. Here’s a tip for anybody who buys these: That little slider on the side only works once it’s on your head. if they aren’t adjusted to that size the slider will spring back. Put them on your head and then adjust the slider.The sound:They have a great soundstage, immense clarity, crisp low end, and highs that sparkle without being abrasive.I am convinced that anybody who has left a bad review of these doesn’t realize their use: They are 60 OHM headphones, they shouldn’t just be plugged into a phone or computer. They are best ran through a receiver or DAC/amp. I’ve tried them on my Quadraflex 300r, and a FiioBTR7 and both make these things SING.They don’t lose clarity with lots of layered sounds (tested with Anderson paak – Heart Don’t Stand a Chance, and The Band – When I Paint My Masterpiece), maintain a clear sound even with complex reverb (tested with Steely Dan – Kid Charlemagne), have GREAT bass (tested with Techmaster P.E.B. – Bassgasm), great low volume response (Intro to The Police – Don’t Stand So Close to Me).If you are a critical listener looking for some headphones to bring in your backpack, suitcase, car, to work, on a plane, you should get these. Just remember they are open back so they will bleed sound, and that you should use a dac/amp if you want the best results.

You won’t believe your ears
Take what other reviewers have said about these headphones, believe them, and then multiply it by 100. I received a pair of Koss UR-20s as a gift years ago and loved them so naturally I looked to Koss again when replacing my portable/on-the-go headphones. After buying a pair of KSC-55s, which sounded great but were uncomfortable for me personally, I hopped on Amazon and found everyone raving about the PortaPros. I figured they were good, especially considering that the design seems unchanged since the 1980s (which has to mean something), but I also figured that this was one of those things that was just too good to be true. However, these are bar-none the most amazing headphones I have ever put on my head. Listening to some of my favorite songs for the first time was one of those ‘wow’ moments where you realize you have found something that changes your expectations completely. The bar will be raised the instant you hear the bass response and incredible acoustic qualities of these light, comfortable headphones.I don’t know what I’m impressed with the most: the amazing bass, the excellent stereo division, or how loud they can get! These things are just as amazing as most of the reviews show them to be and then a lot more… I was worried about the eighties styling, but in person they don’t look bad at all. I hate headphones that scream for attention, but these don’t look like that when you have them on and I have already been wearing them in public (something I didn’t think I would do after only seeing the picture of them online). And even if they’re a bit outdated in appearance, the design is so functional you won’t even give looks a second thought after you put them on.One thing is for sure: these things have plenty of bass! Not too much (not “boomy”), but they seem properly tuned for listening to things without “bass booster” turned on, which I like. Even with the bass settings adjusted high, the bass remains clear and crisp. I’m not sure how much power these can handle without damaging them, but I listen to them very loud and they do not sound distorted or stressed at all. After a few days my left speaker began making some weird noises and it ended up being a hair stuck inside the headphones that I cleared out with canned air. Something important to consider is that these are very open and airy headphones and the treble carries very well outside the headphones (so someone nearby could definitely hear what you’re listening to if you have the volume up loud).Others have mentioned that they felt the headphones were too tight feeling, but I have a very large head and they fit me without a problem. However, if I will be wearing them for an extended period of time I always set them to the “Light” setting on the comfortZone control (which divides the side pressure of the headphones with your temples rather than just on your ears).I already had headphones I was pleased with (Sony MDR-G52s and Koss UR-20s) but I wanted a set of small, portable headphones for use with my laptop and these are perfect. The folding design isn’t something I necessarily wanted, but it is nice. The carrying case they come with (a leatherette bag) is a slightly tight fit and I probably won’t end up using it much since it is not a hard case that would protect them from shock or crushing. Some others have mentioned that they feel delicate or are easily broken, but compared to other small headphones I have had they seem very well built and equally strong considering their light weight.While I wouldn’t say these are bad things about the PortaPros, it is worth mentioning that the headband is metal and will occasionally snag a hair as you adjust it on your head, and that they don’t fold down as small as you might think they would so don’t expect to put them in your pants pocket or something. Considering these are the worst things I can come up with to say about the PortaPros, they are nearly perfect in my book.I can’t say enough good things about these PortaPros! They’re simply amazing. These are the first headphones (or speakers) I’ve had that sound absolutely awesome without adjusting the equalizer or pumping up the bass. They sound good on everything from R&B to Country and everything in-between. I’ve been especially impressed that they pull the bass and highs out of a song without getting that shrill, tinny treble that plagues so many headphones. If there ever was a question about the quality of Koss stereophones in my mind, these PortaPros have put it to rest and made me into a lifetime customer! If you’re like me you’ll wish you had discovered these legendary headphones (haha! how often is that said?) years ago…

No me decidÃa entre éstos y los Koss KPH40Tengo entendido que la calidad es prácticamente la misma, solo que me decidà por estos por el diseño más retroEl audio es excelente, impresionante la calidad que tienen, lo mejor es que son muy ligeros, por lo que si te agachas no se te caen por el peso como pasa con casi todos los audÃfonos de diadema modernos.No aÃslan el audio exterior, por la calidad no lo vas a notar, pero eso es bueno porque puedo caminar y estar atento a mis alrededores mientras escucho música en buena calidadCombinados con un iPod classic es la mejor experiencia de audio, hasta puedo distinguir detalles en canciones que nunca habÃa notado antesY hasta le pedà a mi madre que me tejiera unas “esponjitas” la verdad no las necesita, solo se las puse para fines estéticos.Estoy muy contento con la compra, se ven frágiles pero son resistentes y los he estado usando literalmente todos los dÃas desde que los compré, no me han fallado.

Alright so I got them on a pretty neat discount. Back then I wasn’t willing to pay the full price, and now that I have one I’m still not convinced on the 50+ cad price. Yeah sure it’s wonderful pricing for such a great sounding headphone, but did you ever consider the consequence of taking such a plunge? I mean go on the internet and you’ll either find raving reviews saying these are the best in class, or immeasurable disappointment who foolishly set too high of an expectation to get what they expected: Not good enough.When you buy one of these as a hobbyist, you look back at your audio, wondering where you’ve gone wrong. It’s not quite audiophile enough to replace my more expensive, albeit larger sets of headphones, but it’s not quite bassy enough to satisfy my basshead beast that’s leaching off my life essence (curse you Sony Extrabass and your extra-bassyness that not even the bass the fish can sate my evergrowing lust for extra bass). I’d compare the bass level to what sony throws out on their non-Xtra-Bass lines of headphones.There’s enough width to sound to almost pretend I’m in the place of recording… almost. It just lacks that little bit of something that ruins the immersion. Yeah sure it’s wide, but what’s the point if you’re fully aware that what you’re listening to is only a sample of what the audiophile world has in store for you? The audio listening hobby quickly shifts from a minor purchase here and there to irresponsible spending in a blink of an eye… and before you know it you’ve created a black hole in your wallet where your hund-o’s used to live.That’s what this is, unsatisfying in any way you look at it, if you’ve gotten a glimpse of what it could’ve been with a few more tens, hund-o’s, or grandies to spend.Build quality is competent, but I wish the clamping force wasn’t so hard, and the foam that’s supposed to sit on the head to alleviate the problem doesn’t reach my big, dumb head.Comfort is there, but not enough. The furthest settings for the “comfortZone” (which adjusts how much pressure the earpads assert on your poor ears) is just not light enough for my sensitive ears. I don’t think I can spend a whole day wearing these without my ears getting sore. Good news for glasses wearers though (at least some of them), the pressure is put on the antitragus and the tragus, so though you’ll get discomfort (or at least itchiness) in those middle outer parts of your ears, your glasses frame will likely not dig into your skull! But of course your mileage may vary.The cable is not noisy at all, though I don’t think that matters much considering that these are open back, and you’ll definitely hear the cable whack around furniture due to careless usage.The audio quality, though really good for the price, short of a miracle that everyone claims it to be, and a bit too bassy for ex-bassheads (and not bassy enough for the bassheads). It’s a pretty warm sound, but the mids and highs are present enough to make it seem like it just has that extra bass on top of a balanced sound.Sure the driver units can be popped off and attached to other attachments (I’ve actually gone and put them on a KSC75 earhook), and the foam pad can be replaced with the much more comfortable and better sounding YAXI earpads… however I’m reviewing the product as it’s own… and without any accessories (except a “protein leather” egg bag), this product is not good enough for all the praise everyone’s screaming out…But that’s what it is. Disappointment if and ONLY IF you set your expectations stupidly high based on reviews bowing down before its presence. If you ignore all the fans (somehow) and just buy the product expecting nothing but a 50$-sounding headphones, prepare to have your socks blown off to next sunday cuz this set of headphones is the best retro-style good-sounding headphones for the money!When you buy this, don’t expect a giant-killer; Be humble, and you’ll get more than you’ve bargained for. If not, at least these do well as conversation starters and/or room decoration.

These are fantastic for the price, especially as a gateway into the audiophile realm. Pound for pound they stack up equally with headphones more than twice the price, they punch way above their weight. Open backed so while you can hear everything around you and bleed sound, the sound quality itself and soundstage is likely going to blow most people’s minds, especially anyone who hasn’t used expensive high end headphones before. These are fairly bass skewed if that’s your bag, if you prefer a more neutral mid based sound I recommend the kph-30i. Build quality feels sort of cheap and I think that’s how they managed to sound so good at such a low price. The cables to the earphones themselves are very thin and feel flimsy. I keep them in the nice little carrying case they come in and use them solely at home, so far so good. The lifetime warranty however adds a feeling of security against the cheaper build and is nice to see. They are strange looking and will turn heads, not in a positive sense, but that design comes with some benefits. They are extremely light and comfortable, that alone almost cancels out the ugly duckling vibe.Long story short these offer sound that punches way above their weight and will likely be the best sounding headphones that someone who has always used cheaper headphones will ever hear. The open backed design gives a real soundstage that makes the music sound likes it’s coming from all around you. These come with a high recommendation from me!

De eerste Koss headphone heb ik per toeval gekocht vanwege de kleine vorm, maar was zeer aangenaam verrast over de kwaliteit van het geluid : vol, krachtig, duidelijke bas maar niet dat het zodanig domineert, goed gebalanceerd met de midden en hoge tonen en alles in een lichte, makkelijk te transporteren geheel. Ik gebruik het voornamelijk voor de smartphone. Een ding vind ik minder en dat is de lichtere kwaliteit van de kabel welke te makkelijk gaat krullen en dit uiteindelijk werd het fatale einde van de headphone omdat de krullende kabel scheurde bij het oorgedeelte. Ik ben inmiddels bij de tweede en de derde Koss (allebei tegelijk gekocht) want de headphone is naar mijn oordeel nog steeds één van de betere voor smartphones, qua bouw en vooral qua geluidskwaliteit. Aanbevolen.
