To me the lack of bass on the KSC75 was not really apparent unless I purposefully compared to other headphones. The midrange and treble just feels so nice that the lack of bass and treble extension didn’t bother me.
The kind of sound signature I hate the most is V-shaped. Whether bright or dark, I neeeed a solid midrange. I don’t like my ATH-M40x because of the slight dip around lower-mids. Everything sounds hyped but thin.
Guys, please stop writing the words you’re writing. I have exactly zero need for these headphones. But you’re going to make me buy them lol.
$15 man. Heck if you don’t like the sound you may as well use them as a Christmas ornament. 
IMO trying a Koss out is more about burning a couple dollars for cheap entertainment. Though you can already make a mean burger, sometimes you just want to relish a $1 cheeseburger from McDonalds.
literally me. i loved the 58x, but straight up bought the ksc75 and fully switched lol
From the wise words of Chancellor Palpatine from the Revenge of the Sith:
Get the kph30i’s, sound better imo (i have both) headband for me when im wearing it i cannot feel it, they are clampy at the start, but after a while they are perfect, kph30is with yaxi pads are the best, GET IT PLEASE!!!
I am willing to get it but there is a problem, I cannot see shit from the local online sellers that we have here, let alone trying to buy one in the middle of a freaking pandemic here. But yeah, in time I will buy one if I am able to find one with a good deal, for I have been curious about it for a while ever since its review by Zeos back then.
So you guys told me to get a pair of Yaxi pads for my KSC75s and I did, this is what happened after replacing the stock pads with it and I am going to explain it with one picture below after the pics of the Yaxi pads.
Seriously, What the fuck Koss?!! I knew that the KSC75 is like already hella’ good with even the stock pads, but to put these with Yaxi pads?! like HOW?! How is this even possible? I am literally like that in that picture.
Ha, this post had me a bit excited to check these out again. I had a pair of koss clips in the early 2000’s that were nearly the same looking.
These are $55 on amazon in Canada lol
I just saw, ouch. Can’t Canadians order through the US site for some extra in shipping? Alternatively, Drop has them in black as the KSC75x. Excellent mids and treble, at the cost of a cable with suspect durability.
I want to get the Drop version and mod it… Sale is going to end soon, but it isn’t a good time for me to burn more cash on 'phones. aaaaaaaa
When I get stuff on Drop, I end up having to pay duties. Combine that with occasional awful shipping and Drop is usually crappy to buy from for us Canadians. USD+Shipping+duties is a bummer when the Canadian Dollar is a Peso.
Only some stuff on the US amazon will ship to Canada, so its a case-by-case affair.
Aw, that’s such a bummer to hear. Default price on Amazon seems to be under 30 CAD, so hopefully you’ll see the price drop again.
Canuck here, I highly recommend ordering straight from Koss’s site. I’ve gotten all of my Koss there with no complaints.
Really wish Koss would come out with a full sized open back in the SHP9500/9600 price range.
There are the GMR-545 Air, which apparently do sound quite good.
But then there is the typical Koss catch of shit build quality. :^)
Jokes aside, I would like to see them make a $200+ open-back. D-cups, detachable either side cables, neutral reference tuning. There has been no news on the A/550, but I do hope they are continuing development. I’d happily be a first adoptor lol
Finally got around to “mod” my KSC75s today…
Yaxi pads, and a cheap “headband”
after 15min listening, i think they sound better, and at least for me it seems like the comfort is better when i don’t have the “hook” round my ear. They are sooo light with that headband, and the pressure against the ears is very light, so no complaints so far. I can still move the head around vigorously without any danger of them falling off (the low mass helps on that).
Compared to my kph30i (stock) they feel a bit more open in the treble, and less “veiled” . My koss porta pro with yaxi pads are not at nearby right now, so i can’t make that comparison, but i would guess the pads are the biggest part of the treble difference vs the kph30i.
As for the bass, a bit more pressure to the ears adds a little bit i feel.
All in all, i would call it a Great Success! 
I believe that I have finally reached to a higher plane of understanding when it comes to sounds after doing this mod to my KSC75s. It felt so different but at the same time much better than the previous earhooks that I have been using, and I love the comfortable pressure that I feel from these since I don’t mind a bit of clamp. Overall, this mod is a quality of life improvement.
Guess I’m gonna have to buy two of them. One for clips, one for headband. Heck, I may as well by 4: 2 extras while the first two will undoubtedly have wire failure in 2mo with how bad my luck is :^)
These things are more bass-light than I remember. There is decent enough kick, but everything below 100Hz is kind of gone in a lot of the electronic music I listen to. Still phenomenal. The treble 
Also, I though clips would be less bothersome than a headband with my overgrown hair, but it’s the opposite. I really need to get it trimmed.
