Koss Porta Pro vs. KPH30i vs. KSC75 - The BEST Walkman Headphones

[@Slapo007]

Interesting comparison. Of the three, I only have the KSC75 (which I have modded a little) they hold their own well even against significantly more expensive headphones. They generally lack the detail of higher end headphones, but the signature is good for pretty much anything I've used them for. They do have a decent level of detail, too, but you can only do so much on a budget, I guess. I have a tip on how to put them on easily: Try it like with glasses, with the ends of the clips going behind your ears. Then you can just rotate them into position. Once you do it a couple of times, it becomes quite natural and very fast.

[@SuperReview]

I'll try it out ✌️ I did the PartsExpress headband mod, but the part that ships from Amazon now is different from the headband most users recommend. It still works, but requires some effort...and the headband is too small for head. At max size, it doesn't fit on my head unless I tilt the whole unit forward.

[@Slapo007]

Please do. :-) I had tried the Parts Express headband too, but the two I got (yep) had too many sharp edges and were just too thin so even a slight tilt made it uncomfortable to wear despite weighing almost nothing. I ended up binning the headbands. I also tried the SOL republic headband but it clamps hard enough to kill some of the airiness that's so nice about the headphones. The clips really comfy and you can bend them a little after removing them from the ear cups, as they're basically a steel wire in silicone. Helps tune the hooks for larger/smaller ears. The mod I did to my KSC75 is called the Kramer mod, I think. Basically, punch a couple of holes into the plastic cover in front of the driver. There's a couple of videos of this on KZbin, too. It boosts clarity and treble a bit (the mids too, but less so) and I quite liked it. I also found using an equaliser helps get them to sound even better, especially for something like games and spoken word. I don't have the exact parameters, but that's really because I have a program called FXSound Enhancer and its Fidelity and Dynamic boost sliders are really nice for quick tweaking and I found they work pretty well especially for games. They can probably be mimicked using an equaliser, but I haven't managed to get it quite there myself.

[@bri_oni]

How'd you mod them?

[@SuperReview]

The KSC75 speakers easily pop off of their clips and can be then snapped onto a headband.

You don't need the parts express band, you can just pop them on the portapro headband.

@@SuperReview You can put the yaxi pads on the kph30i's as well! They improve the comfort and even the sound in my opinion. Unlike the porta pros, you do have to take the earcups apart and it's a pain to do if you don't want to destroy your original pads. I think there's a few videos on how to do it on KZbin though

Great comparison, as they say around here, “you deserve more subs”. From what I’ve read the KSC75 and PortaPro driver units un-clip and are interchangeable. With a bit of clamping pressure the bass improves x best of both worlds!

They are indeed interchangeable, though I recall it being kinda hard to get the KSC speakers in and out of the PP band.

The trick I have learnt for the KSC75 is to go to the local electronics store and buy the cheapest headphones with the clip on headband and replace the ear clips of the KSC75 with the band. The KSC75 have a great sound and sit nicely on the ears with the headband especially at work where I wear them most of the day, also doesn't leave you totally isolated with what is going on around you.

[@SuperReview]

I also appreciate not being isolated 👍

[@richardalangreen]

I did the same conversion to a cheap clip-on band, buying a $7 Parts Express headset from Amazon as the donor, and you get the best of all worlds: the KSC75 sound, slightly better positioning on the ear, much more convenient and comfortable slip-on headset! You just gently pry the KSC75 drivers off of the earclips, pry the terrible drivers off of the Parts Express headset, and pop the KSC75 drivers onto the Parts Express headset. Here's a link with photos describing the conversion: www.head-fi.org/threads/simple-ksc75-to-headband-mod-easy-as-pie-pics-56k-maybe.232714/page-14

[@kylevanwagn3r]

I've been digging your videos a lot. I got a Walkman about the same time as your review, and the Porta Pros a couple days later. I love the Porta Pros, but they definitely get a little muddy toward the high end. I recently picked up a Dragonfly Red because my laptop's on board audio was horrible, and it's changed everything. The warmth and thump of the Porta Pros that I love is still there, but it's eliminated the muddiness and cleaned up that high end. I highly recommend a Dragonfly Red to anyone.

[@SuperReview]

Do you get the same effect using the Dragonfly on your Walkman? Or just on your laptop?

[@kylevanwagn3r]

I'd actually say that the Dragonfly Red and the Walkman are neck and neck when bringing the best out of the Porta Pros. The Dragonfly brings a little more soundstage and a little better imaging, but by a very slight amount. I haven't tried running the Dragonfly through the Walkman, but it seems pretty unnecessary after doing a direct A/B comparison on a few songs. They sound extremely similar. I had just gotten so used to the Porta Pros from the jack on my laptop and hadn't touched my Walkman in so long I forgot how much it brings out of them as well. But they definitely still sound muddy when in direct comparison to the KSC75's, but the KSC75's sound too sharp for my tastes. I love the warmth of the Porta Pros.

[@doctoranthonyf]

Yes, FWIW, many people find the KSC75’s to be quite bright, artificially so, sibilant/sharp. And further, they lack/subtract bass, bass that should be there. The Porta Pro’s, many consider (not all because it’s opinion, unless measuring) to have a better balance in music representation. The highs are representative, rather than emphasized-as with the 75’s, and the bass is full and foundational, it has proper authority. Thus it’s tremendous and deserved reputation, one the KSC75’s will never have. However, what are probably the best $15 headphones available today? Likely the KFC75’s! They are a tremendous value! Enjoy!

[@SuperReview]

Lemme know what you think.

[@andrea585ny]

Thanks! Been checking reviews for KPH30i and yours was very helpful. The 75s are "Wow!" headphones. Porta Pros on the other hand need a little help. If you try replacing the stock pads with Sennheiser HD414 pads I think you'll find them more enjoyable. They move the drivers further away from your ears and give the bass a bit more room to move. Makes em sound less muddy and congested. Cheers!

[@SuperReview]

Great tip! I agree the KSC75s are immediate wow. I think the KPH30i is somewhere between the KSC and Porta Pro -- I'd be interested if they sound at all like the Porta Pro with those Sennheiser pads 🤔

[@andrea585ny]

I didn't much care for the sound of the PPros until I replaced the pads. It does make a world of difference not only with sound but clamping pressure as well. Now you can put those soft PPro pads on your 75's. (Btw the Sennheiser pads are yellow, I dyed mine black 😉) Happy Thanksgiving

[@daladirn5119]

I use the Porta Pros and have been using them for about 8 years now. I have a larger head, so they are fully extended. I don't really notice any clamping pressure because of that. I never had an issue them sliding like you've shown and they feel very comfortable. Since they do not slide and setting them up is super easy, putting them on, even when they are folded up, is super fast. I never have to fiddle with them once they are on my head. Biggest issue is probably than once a year or two I need to replace the foam pads, because they got so worn out, that they fall off easily. But that's also because I often fall asleep with them on and the pads experience forces which they shouldn't. Awesome thing about the headphones is that if you turn down the volume or turn off the music completely you can hear everything around you very well, so they are awesome when you're walking outside, because you're still aware of your surroundings. EDIT: I want to add that the cable on the basic Porta Pros is very rigid. I don't handle it with care, but it's still working without issues. Only thing about it was the jack, which started having issues after a few years of heavy use, so I replaced it with a metal jack that's very rigid and been using that since.

All joints are made of silicone, the design does not make noise, the cable does not make noise when in contact with clothing. Finally a modern cable with a good microphone and plug.

I tested the PortaPro and KSC75 side by side with FLAC files to make sure they received as much information as possible. There is no possible comparison between them: the PortaPro has generous bass and a very pleasant sound altogether, the KSC75 totally lack these bass and the sound is much less enjoyable. There's no way to adjust the pressure of the KSC75 on your ears unless you bend them with pliers. Both are very comfortable. Their weight and size and the fact that they are foldable (PortaPro) make them perfect travel companions with minimal to no compromise on sound quality.

First of all, I love the Grado signature sound. Coming from the Grado 125i’s I think the comparison of the Koss KSC75 and KPH30i headphones is accurate. I am happy that I bought the two for my portable audio setup. I still think that the KPH30i are “muffled” compared to the more open back Grado’s but I would not fault it as it still has an amazing sound! I think I’m just used to the high-mids and high frequency bias of a Grado headphone. The KSC75 are indeed more comfortable and does sound similar to the Grado’s. I like that it’s more portable than a Grado and it has microphone! So, I can use it to take calls from my phone.

KSC75s are a gateway drug. They are so good for the price that it will start you on your audiophile quest. Hard not to recommend them as a starting headphone.

I think they are a newer headphone for Koss. KSC75s are like $15 at amazon, sportapros are $22, KPH30i and portapros are about $30.

[@HDEditor6]

Nicely done review. Good catch on how the cord behaves differently with a hoodie and I suspect you are right about the extra thickness of the cord where it enters the earpieces. Regarding the clamp pressure on the Porta Pro X, did you try the "Comfort Zone" adjustment on each earpiece and did that make any difference in wearability?

[@SuperReview]

Yeah, the ComfortZone adjustment helps. I think it's still more clamping pressure than the KPH30i, but the bigger problem for me is that ComfortZone switch is another thing that resets when you take off the headset. I even think the sound improves a bit when the clamping pressure is reduced. But it's yet another (small) hassle that's not applicable to the KPH30i :)

[@artheen4713]

One problem with the Porta Pro and its "Comfort Zone" is for those of us with above average size ears - i.e. people above the age of 40. The top of the ear extends between the ear pad and the comfort zone, and rubs against the folding hook. This is very uncomfortable, especially for the new model where the hook isn't even filed down to be smooth, but is cheap stamped metal with sharp edges. I am on my fourth set of Porta Pros (that's how much I like them), but the first thing I have to do is dremel off the hook. One good thing is that Koss sells replacement pads both for the ear pad and the comfort pad, and if you switch the comfort zone pads out, you can cut them down to size or pad them to be thicker (by stacking two pads on each side and an xacto knife).

[@rgl8109]

The clamping is adjustable i three steps. At least on the ones l have.

[@PhoggHawk]

Soundwise, my least favorite of the 3 is the KSC75. My favorite is the Porta Pro. I think they have the best bass, crisp vocals and micro details. Once adjusted, and with the Yaxi pads, they are incredibly comfortable. I don't like the Porta Pro with the stock pads. It digs into my ears and is uncomfortable. They are nearly the exact same stock pads as the KSC75. I ended up putting Yaxi pads on both, actually. Much more padding and area for resting against your ears. I really like the KPH30i, and it is very similar to the Porta Pro in sound, but I still think the Porta Pro is slightly better in every sonic category. I once highly recommended the KPH30i, but I don't recommend it over the Porta Pro for longevity or sound. For the price, being less expensive than the Porta Pro, the KPH30i is the sweet spot, though. My Kph30i is the clear one and both sides of the headband have broken. I have it held together with clear tape. I think the other colors are a different type of plastic, so they might be a little bit better. I gave them to my 10 year old son and he uses them for gaming with the microphone. Of course, he is the one who broke them, lol! So they aren't kid proof. All three of the Koss headphones are exceptionally good for sound, so you can't go wrong with either one! But the Porta Pro with Yaxi pads is the king!

Do people actually care about how headphones look like? I mean seriously it blows me away that some people would rather go with shitty sounding headphones just because they're more "fashionable".

[@AeonTrespassField]

@@SuperReview I don't see what that has to do with anything. I don't give a shit how fashionable a pair of headphones are if they sound like ass, and once I gifted all of my family and friends some mid-tier Sennheisers or AKGs they all felt the same way.

[@MrR3DP4ND4]

@@AeonTrespassField You're assuming that headphones that look good sound like ass. If you had two pairs of equally good sound by every measure, and one looked good while the other looked like ass, you would clearly pick the one that looks better.

[@AeonTrespassField]

@@MrR3DP4ND4 That's misleading as no two headphones are ever going to sound exactly alike, there's always going to be some sort of variance in the sound signature, sound reproduction, soundstage, etc. And so when it comes down to it I'll choose the headphones that sound the best for me for the music that I listen to, irregardless of what they look like or not.

[@MrR3DP4ND4]

​@@AeonTrespassField Not really. You posed if people actually cared how headphones looked, so I gave you a hypothetical to show that yes, people care how headphones look. If there are two headphones and the only difference is the colorway, you're obviously going to pick the one that looks better.

i am torn between kph40 and koss porta pro. i like to listen to music and watch movies for hours while getting little to no ear fatigue. the porta pro is $60 and the kph40 is $55, which is more worth it?

[@trxbloke]

You can adjust the ear pressure on the Porta Pro.

[@SuperReview]

ComfortZone 😎 Kinda awkward IMO, but yeah, it works.

[@trxbloke]

If you find the pressure setting you like (for me the mid position), put a bit of matchstick in the mech to stop it snapping back to the tightest setting. Then it will always be easy to get the perfect fit. You can also loosen the band curve a bit, though it will tighten back up if you fold to fit in the bag a lot.

[@ADcrackerjack]

Great video man. One question, is it just me or the KSC75 requiere more volume compared to the Porta Pro? The voices sound crispier but I need to turn the volume like 20-30% up compared to the Porta Pros, maybe it’s the more open back? Or do headphones with more bass sound louder? Anyways, I’ve owned the Porta Pros for more than two years know and love them. About a month ago I got the KSC75 and they’re indeed impressive, the best way to describe them is as airy, the soundstage is notorious and the male voices pop out, you can hear your favorite music and hear details you didn’t know were there. For the price, they’re unbeatable. Thanks in advance man!

[@SuperReview]

I don't recall a significant volume difference between them but been a long time since I listened back to back. I wouldn't be surprised, though -- the KSCs get their airier sound by being physically further away from your ear.

[@ADcrackerjack]

@@SuperReview thanks for your response bro. Indeed, the open back may the reason why it sounds like that to me. I just need the KPH and this golden trio will be complete. I mostly use my Porta Pro for gaming but I own the ones without a mic, so getting the KPH sounds interesting to me, although I know the mic isn’t that good, but it’s something 😌.

PP have a comfortzone design, but that doesn't help a lot cause of PP's clamping force. I put 2 foam pads on kph30's headband, like PP, I can wear them longer now.

[@SuperReview]

I put some Yaxi pads on my Porta Pro, good improvement to comfort AND sound signature, IMO.

[@alexanderjarvis9827]

I felt the same way you do about the KSC75, however you might want to try bending the earclips. There are tons of videos and posts online about it and how to do it. It can help the fit, and, because it fits better, bass gets a bit better and more present and the mids get just a tiniest bit more body.

[@SuperReview]

I don't mind the bass out of the KSCs, my only serious gripe is that they take longer to take off/put on than a standard headband.

[@veegs23]

I own both the normal Koss porta Pro and the Massdrop Koss porta Pro X and I definitely reckon there's a difference - THe massdrop ones have more muted mid and treble and an enhanced bass, as well as being a little less efficient. I reckon the original koss porta pros would be more similar to the KSC75's

[@SuperReview]

For real? I have heard anyone else say they're different. (FWIW, I've only listened to the Massdrop version.l)

[@DGardn100]

@@SuperReview Interesting. I've had the Massdrop version of the KSC75, for a couple of days, and they don't sound much like what you describe in this video. They sound a lot more like Veggieburger's description of the Massdrop Portapros.

Good review

[@SuperReview]

Thanks mang.

[@esafaramarzian]

the way you should use the porta pros is you set it to max size put it on your head and press lightly from the side and boom no fuss it's a perfect fit no pulled hair. they should put that in the manual. and if you feel the pressure is too much you can flick the switch on the sides and man you've got yourself the comfiest headphones

[@SuperReview]

I ended up adding some gaffer tape to the headband to hold it at the right position for me, I like it.

I really appreciate your work. I have a little question. I love the design of pp but i love more the soud of ksc75. I've seen that you've swapped their drivers. Are the ksc drivers on pp headband better than the pp itself?

[@SuperReview]

I've found that the bigger difference is how close the driver is to your ear, rather than which driver it is. IMO, putting Yaxi pads on the Porta Pro improves the sound a lot by holding it further away from your ear. It's not quite KSC sound, but it's closer.

Bro, the Porta Pro sound super loud. They’re amazing. The KSC75 sound clearer.

[@Schmidteren]

Can I take them off and put them on the KSC75 shell? I know you can do the opposite, so this should also work, right? I love not having a headband. :)

[@SuperReview]

Yes, it works. Koss also sells the KSC35 which is basically Porta Pro speakers on clips

[@TDK2K]

the KSC75 and Kph30i have the titanium driver whereas the Portapro uses the regular original 60 ohm driver.

[@DroidLocks6971]

my humble take . . . ksc75 more subdued compared to kph30i and the kph40 is probably the best all aroumd performer of the 4 . the 4th being the porta pro has the hardest hitting bass especially with tha factory pads before i switched the porta pros to yaxi pads . you honestly cant go wrong with any of these but if id to give 1 away itd have to be the ksc75 . i did the ultra mod for the kph40 and it destroyed their excellent sound but its easy to undo this mod and this brought back the wonderful inpactful sound of my kph40

[@rsdno]

I have all three and even 2 pair of Yaxi it is great to review Koss as it is interesting the same driver can sound so different KSC 75 is #1 the 30i is #2 and Koss with Yaxi is great too I see no loser my Pro4AA kind of fell apart

[@SuperReview]

Nice ranking.

[@MrStubbs8157]

Isnt the ksc 75 different in bass and more mid to treble because it has the Titanium driver? 40, 30 and portapro has the normal drivers...hence the differences are a little different tuning...porta pros are generally dark throughout and 40s seem to have an elevated mid again? Also: K40 headband should fit as well but I dont know if they sell them as a spare part. K40, porta pro and ksc should all fit each others headbands...not sure about the 30s but should be as well.

So is there no difference in sound quality between these porta pros and the originals?

[@brandonuchiha8231]

Thanks

[@artheen4713]

I have both old and new PortaPros. The original ones have separate and thicker cables side-by-side instead of a single thinner cable with both wires. The main difference is that you lose less treble to crosstalk with the old ones, and can also pump them up to higher volume without distortion (if you use a headphone amp - you're not going to get anywhere near max volume with a mobile phone or sub-$500 walkman). I prefer the old ones, but they are very close, especially if you don't blast your ears. If you do, go for the old ones. If you want volume control and mic, and a better connector, go for the new ones.

@Jacob - if you haven't already made a decision, I use the KSC-75s with my Rift-S. Definitely better than the built-in speakers. If you find just wearing the headphones to not be comfortable enough, you can mod the rift in several ways to attach them to it. Be advised however if you go all the way and disassemble the Halo band to run the wires through, it's not as easy as some of the instructions make it out to be. Have a microdrive screwdriver on hand, a clean place to work, and a dish to set all the tiny screws in.

Yeah, I got a pair, don't like 'em as much as these. The build is really bad -- I mean these other Koss are cheap too, but the URs feel much more flimsy IMO. Sound is also not as good -- same driver as KSC75 (I took my UR40 apart) but the housing gives it a warm, flat sound IMO.

Have the 30i, the 75 and the 40s. The 30i with huge grado pads. For me the 40s are a bit bassier and the clamp tad too strong. The 75s need the clamp to be adjusted (remove the hook ply it and reassemble) so that you get the bass back. They'll sound just great that way. The 30i with the pad are in a different ball game. The whole frequency range is just great. They become spacious and beyond amazing. The 40s don't go well with the grado pads as they become too shouty imho. Like them a lot though but not as much as the 30i with the pads. Btw kept the original foams just put the grado pads on top.
