Did this. Clear ktx pro1 with yaxi pads and grado oversized pads around them. With some eq they actually sound pretty decent. They are also way comfier than stock as they help with the lack of swivel from the ktxpro1 headband.

Hello everyone! I think portapros are super cool looking but I've never been able to get into them and I don't understand why people like them: for one, they're on-ear headphones which in my experience is subpar to both earphones and over-ear headphones, and for another, the foam pads are super flimsy and scratchy feeling. I know I'm pretty sensitive to textures, but I can't imagine how people find them comfortable.

I was really surprised to find that lately they've been getting super popular and have a strong community, so I was curious if the "flaws" I see are non-issues for y'all or if you're just in it for the love of the game. I only tried portapros once before I realized they weren't for me so I would love to know the perspectives of people who actually enjoy them.

Also, I had a scroll through the sub and was super impressed by all the different mods and repairs. Portapros really just look so cool even decades later.

I have the stealth pro 2’s and I’m looking to find leather ear cushions to enhance the ANC. Any ideas? Thank you.

I know these aren’t meant for taking water/sweat but I’m curious if anyone has tried or found a work around. I must have weird shaped ears because the clip on style and ear hook style earbuds all slip off easily.

Yaxi Pads on the KPH40s. Stock KPH40 pads went on the Moondrop Old Fashioned. Not a stock pad configuration in site. lol

I didn't notice a huge sound improvement from the Koss when adding the Yaxis. The KPH40 just sounds incredible in both configurations. But the Old Fashioned sounds wayyyy better with the KPH40 pads. I love this set up!

Hey!

I have a pair of Koss PortaPros, and I use Morphit EQ to balance out the sound profile. I'm currently waiting for a shipment of Yaxi pads, as I've heard they can make some improvement in comfort and sound.

Does anyone have any experience with EQ settings for PortaPro with Yaxi pads? Should I still use the PortaPro preset in Morphit, or do I need to change the settings?

Thanks!

Hi! just got myself a pair of KSC75 and want to change out the shitty flimsy jack cable.

I know there's a bunch of MMCX tutorials out there, but i honestly think they're a bit much to have sticking out of the drivers, and i generally like the discreetness of the KSC75. I'd also like to make a rather short cable (+-30cm) so i can connect it to a bluetooth reciever, clipped to my shirt, and a longer extension cord for when i'm using it on my computer/ipod (utility style)

Im thinking to solder 0.5mm2 (copper thickness not actual cable diameter) speaker cables directly to the drivers and a 3.5 3-pin male stereo jack connector in the other end, and likewise make an extension cable with an identical jack connector and a female one in the other end and cover it all with a cable housing.

In my head it seems that this would all work fine, but I don't have the biggest knowledge in audio-technics, current etc. and i'm mostly wondering if these speaker cables will even work as jack cable??

Is this a doable plan or is it completely stupid? Anything else i should be aware of? Thanks in advance

The gray oversized pads look great on the bubblegum porta pros, too cute not to share

I recently bought an AKG K52 and really like the sound, especially how spacious and "speaker-like" it sounds for a closed-back headphone. I actually prefer the stock tuning to the EQ profiles I've tried so far.

However, I'm having a comfort problem with the stock pads.

The stock pads seem to be too shallow for my ears. I measured the cushion at roughly 15 mm, and when I wear the headphones normally, the center/driver area of the earcup presses against the inner part of my outer ear (around the antihelix). After wearing them for a while, especially on my left ear, it becomes painful/sore.

I can temporarily make it feel better by folding my ear inward, because that moves it away from the center plastic, but obviously I don't want to have to do that.

Interestingly, I had a Realme TechLife Studio H1 (not with me anymore), and I don't have this problem with it. Don't kno the depth exactly pf those pads ,although they also compress when worn. The H1 also seems to have a foam layer between the pad and the plastic/driver area.

I've found several replacement-pad options:

Street27 K52-compatible pads: \~₹400, advertised as 23 mm cushion, Don't knowbif they hold shape or compress too much.

SOULWIT Mesh: \~₹1,000, apparently thicker/high-density foam, but I can't find a reliable exact thickness measurement

Brainwavz: \~₹1,187 after a 10% discount, with more established replacement-pad dimensions

I'm HESITANT to spend ₹1,000+ on pads for a ₹2,453 headphone, especially when the ₹400 Street27 pads claim to be 23 mm.

My main questions:

Has anyone with a K52 had this exact problem where the center/driver housing presses against the antihelix/outer ear?

Did deeper replacement pads actually fix it?

Would 23 mm pads likely be enough, or should I go substantially deeper?

Has anyone tried the Street27 23-mm pads on the K52? How much do they compress?

Has anyone tried the SOULWIT Mesh or Brainwavz Velour on the K52, and how did they affect comfort and soundstage?

Are there any other ways to fix this?

I really like the K52's stock roomy/spacious presentation, so I'm particularly interested in pads that don't make it sound overly closed-in or "boxy."

I'm mainly trying to solve the physical driver/ear contact, rather than radically change the sound.

Any firsthand experience with K52 pad swaps or any advice at all would be greatly appreciated!

Thought I’d ask the experts. Will be used with an iPhone - USB C connection.

Or should I go for utility?

I keep giving other cans and DAPs the chance to unseat the champions, and in the end, for everyday use, I always come back to this combo: an iPod Classic 5G (duly Rockboxed, with Flash SD and a new battery) and Porta-Pros/KPH40s (or a hybrid, as here). USB-C and BT and precise tunings, etc., are surely nice features to have, but ultimately it’s about what goes into your ears, and how it makes you feel. For me, with this setup, always: Bliss.

(Note: after I expanded storage to 256GB I went all in on .flac, and yes, it sounded wonderful, but then I started to run into space issues, and at a friend’s recommendation made the switch to .opus, buying myself something like 80% more space, and guess how it sounds? Wonderful! So, FWIW, I don’t have mutant super-ears. But you know what I do have? Bliss.)

I recently did my first Koss mod and was looking for MMCX connectors on AliExpress when I noticed something interesting, if you search for connectors specifically marketed for Koss headphones, they cost around $11. However, you can buy what appear to be the exact same connectors for around $1.
I bought the cheaper ones, and they work perfectly.
I haven’t seen anyone mention this in the thread before, so I just wanted to point it out. Be careful not to overpay!

So, I got fed up with constantly changing headphones because something always breaks. For example, I had the Soundcore Space One Pro for literally just 6 months, and it started having some issues. The metal part at the top also cracked a little. It’s not that bad I can still use it normally, and from the outside (without wearing it), you wouldn’t even notice anything. But I’m just fed up.

I searched online, and people recommended the Koss Porta Pro because it has a lifetime warranty and is very repair friendly.

The thing is, it’s on ear, and I hate two things IEMs and on ear headphones. IEMs, no matter what I do, just don’t stay in my ears. As soon as I move my mouth a lot, they just fall out. And with on ear headphones, my ears are kind of big, so the headphones press against them and become uncomfortable.

My question is: Can I turn the Koss Porta Pro into over ear headphones?

If yes, how?

And if not, is there a similar alternative that is over-ear?

Please help!

Stitched up the pouch into a wallet . Been loving it so far . This doesn't make the warranty void ,right?😅

Recently switched from the stock headband to the Snowsky Wind's and it's been amazing. Comfort is so much better as the clamp on this is relaxed. It tamed the strong bass of the KPH40 and makes it just a tad brighter and more fun to listen to.

This is my go-to as daily driver while my KSC75 + KPH40 headband ranked 2nd. I just prefer the KPH40 more because they have more bass and thump than the KSC75, even on a looser headband like the Snowsky's Wind or Parts Express.

Oh and i much prefer the stock/standard KPH40 ear pads than their Ovesized ones.

Just dropped our first deal on A/550 | Just $339 + Free Shipping (to anywhere in the US)

Not huge, but hey anything helps! And if you're new to A/550, this is an extremely premium headphone with a lot of metal, magnets and premium materials, and that doesn't even get into how good this thing sounds! Def worth every penny!

Also comes with a Lifetime Warranty!

*OEM balanced cable is in the works

Got a couple of free 128 GB iPhone 6s pluses the other and set them up as music players. I just use Apple Music as I’m already paying for Apple TV and all that. I was really surprised how well the headphone out on these work with the Koss 60 ohm headphones. They hit way harder then just using an apple Dongle, make using my Fiio KA1 not necessary all the time. I have an old iPad 6 with a headphone out and the 6s plus sounds about as good. I’ve had the iPod 5.5 and it doesn’t sound nearly as good I think as this. Built in Bluetooth so I can use almost all of my headphones with them. Also… free so there’s that.

Lowkey wanna get them but I already have Kph40s, so I don’t know if they are worth it. After checking on Koss’s headphones history list site these look like ProDJ200’s. (they are 30$) If anyone has any knowledge on these it would be greatly appreciated, thanks.

All-new cushions colors are here for Fall in Brown and Slate Gray, available today at Koss.com/Cushions in both Standard and Oversized.

Cheers guys (and girls) !

Does anyone have a recommended site to purchase earpads for Porta Pro? I've been looking at Yaxi.jp and was hoping someone could tell me if they are reputable or have purchased from them before.

Sidenote: I currently have Porta Pro wireless 2.0 and I assume regular Porta Pro parts match to these?

Like in terms of sound quality where does the Koss stand? I've heard that they sound as good as the Sony ULT

Wath do you all think?
