I did get the 75 to test fit into the 30i cup fine. I was just thinking the possibilities out further. If the 75 was out of its assembly, what other possibilities are there? I had forgotten about that post. Thanks for the reminder.
Do you think there are any advantages to the 75 driver that the 30iās canāt be modded to sound like?
I guess there is only one way to find out.
I donāt have the technical skills to really say if they can or canāt be but the 75ās does have a different type of titanium coating on them for tuning purposes so it does have one small advantage over the 30i and porta pro drivers. I donāt know how easily the drivers are removable because I had a bunk pair that came from Koss and when I tried pulling out the driver it was glued into the housing and ended ripping the diaphragm. If you come up with something new it would be great if you could share it in this thread. I love tinkering with stuff thatās on a budget.
I dont really listen to music on these headphones. i use them for watching youtube and such. well I was just watching the latest video of 8-bit guy and the end music sounded so good i couldnt believe it. Great bass and soundstage. these little headphones are really amazing
I finally got my Yaxi pads and got them put on my 30iās.
After running through my test tracks I am really liking the sound. I am finding some more low end presence, along with some overall increased punch/dynamics (probably because of the ācupā the pad creates between the pad and ear).
The beauty of it I find is that with the increased low end, I am not finding any real loss of high end. I am still getting really nice sparkly cymbals, clear acoustic guitars, etc.
Mod 1 complete. I have ideas for diffusers I might 3D print, as well as something I am working on in CAD right now. I am hoping to get the latter printed soon to try it out.
My pair with knock-off grado pads from Amazon (I donāt recommend), wrapping around the stock pads. My headband broke and I ended up 3D printing a poor clamping solution. Ordered a second pair from Drop and have Yaxi pads (originally on these) ready to go. Super dumb, super awesome.
Iāve taken the liberty of using the new DIY section to create a new thread on the updated detachable wire mod. It uses 2-pin instead of MMCX for reasons that I will explain in that thread. Also a better way of affixing the connector so that it can bear the stress of having the wires attached and detached constantly.
I have a 3D printer but no CAD skills. Tell us how it goes!
Was really interested in trying these pad change, sorry for the unfortunate snapping, this happened to my pair as well on stock but I did a superglue repair making the adjusters unusable, now I think I really canāt try this pad swap.
BTW have you tried them without the stock pads? Wondering if theyād be great for gaming on those huge pads, improving soundstage and imaging or did you mean you donāt recommend the pad swap mod at all?
The problem with the pads is they just arenāt comfortable. They are more itchy and dense compared to the Yaxi pads and thereās a bit of distortion. Feels like a bit of an echo chamber. Iāll remove the stock pads and try them again with just the big pads - I should note that there may be better big pads floating about. These are the pads I got, but I donāt recommend them: https://www.amazon.com/gp/product/B071VXQNR9/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
Re snapping - I had tried superglue as well but due to where my snap happened there was a ton of flex strain on the area and glue would slowly lose structural strength.
I finally got these in the other day from Drop - I ordered a pair for my brother and decided to get a pair for myself also to see what the hype is all about.
lol, itās all true - these things are crazy good for the value. I plugged them into my SDAC -> JDS Labs Atom and Iāve been watching videos, listening to musicā¦ wow. Damn. Really, for $30 (I actually got them for $20 on Drop) these are ridiculous.
Only thing Iām not really digging are the stock pads. They feel scratchy. Itās nice that they donāt move very much on my head but when I take them on/off or adjust them I donāt like how they feel on my ears. Looking to invest in some Yaxi Padsā¦
I think that scratchy feeling will go away with use. Sounds like it will be going away fast for youā¦lol.
Definitely the best headphones for the price, they easily sound as good or better than headphones that cost 2 or 3 times the price.
Okay, Iām back again. Been listening for a solid 6-7 hours now.
These things are straight up God-tier. I love the sound signature. Yaxi Pads are ordered now and these just might be my mains for a while! How is it possible that Iād rather listen to these right now than my DT770 or 6XXās?! They have such a nice, punchy bass/low end.
They sound good but I wish they had the detail of Blon B20 or LCD X.
These things do cost $30. Letās keep it in perspective. Kossā miracles have their limits. 
I finally got around to installing the Yaxi pads on the KPH30I and Porta Pro. I like them visually, I donāt know if Iād say the sound is a night and day difference. I think that is a good though, I stand by the KPH30I sounding way better than the $30 price tag would let on. I do think the Yaxi pads have expanded the sound stage a little bit and the comfort ( wasnāt a problem before) is also better.
Overall the Yaxi pads just make something good just that little bit better. PLUS- they look cool!
Totally agree. Bud in my case comfort also improved as yaxi pads are a bit more fluffy 
love the sound for 22 euro super-nice
Got mine today from Drop. Absolutely floored by these. Got two for the price of one with some of Dropās reward credit. Dadās gonna be happy on Fatherās Day.
I think the unintended ring that forms around the kph 30 I perimeter does a lot for comfort and Sou d stock you have the whole pad arou d your ears with yaxi you just have a right giving more space and the added space between the driver and your ears purely due to the pads thickness and air around your ears definitely make it sound noticably wider and overall just better
Yep, that pretty much sums up my logic too.
These definitely look funky! How do they sound like?
