...did you just screenshot a note and upload the pic? Respect for doing it the hard way.
As for your question - buy a Fiio bluetooth dac.
I recently bought a pair of AKG k712 Pros, which for the most part I liked, but there were two things that made them very uncomfortable for me:
The ear pads were too shallow, my ears touched the drivers
They would gradually sink down until they were resting on top of my ears.
So, a lot of ear pain.
To fix the first issue I tried Dekoni pads. They didn't work - they were about the same depth as stock, but even squishier, so as they compressed my ears actually touched the driver's more.
I ended up taking the tuning foam out from behind the pads. That's probably blasphemy to some people, but comfort > sound, in my opinion.
My fix to the second issue is outlined by the photos on this post.
I had some microfiber velcro cable ties laying around (https://www.amazon.com/gp/product/B085F2LWW6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1), which I realized were about the perfect width to space the ear cup suspenders to keep them from rising too much and lowering the cups onto my ears.
You simply take a single velcro strap, trim off the clasp end, then cut the remaining length into 4 equal pieces.
Wrap each one tightly around the orange frame, with the soft microfiber side facing in, so that the suspension system can't fully stretch out.
If these are too thick, you can use scissors to trim the width of each piece. If you need more thickness, use multiple pieces, trimming as needed.
For me, I actually had to trim the ones on the right cup side, but for the left side the tie thickness was perfect as is.
There are usually two standard connectors for IEMs. 2 Pin and MMCX You can get adapters, like this Hope that's what you're after.
Not those particular headphones, but I just did a scratch build and wanted bluetooth functionality.
I'm very happy with them.
Converted my DT 770 Pro's to use a 4-pin mini XLR connector and made this short balanced cable for strapping a Qudelix 5k on the headband. It's based on this cable, with a Rean RT4FC-B mini XLR connector on the end.
It was a tight fit to get that cable in the Rean connector, but it worked out. To anyone else thinking of doing something like this, just know this cable uses enamel coated copper wires, so you'll have to burn/scrape the enamel off before you can solder it. And protip for sliding the rubber boot onto the cable: heatshrink the cut end of the cable to hold everything together, and then shove that through.
The connector in the headphones is a Redco TB4M, I followed this guide throughout the process, although they use a 3.5mm connector instead of a mini XLR. The mini XLR is lower profile than a 3.5mm so you don't need to cut the driver ring to make clearance for it, however it's also wider, so you need to be careful in how you place it to avoid interfering with the driver's seating in the earcup. File mostly towards the outside of the earcup, and align the flat on the connector with the front where the driver sits. I ended up using a small 3D printed washer to help align it and to conform to the curvature of the headphones, and then just epoxied everything in place.
You can see it is glued layers of foam in one pic.

This is the mod I was talking about and this is pretty much exactly what I did to the 3 I have except I used a different jack. It's not difficult just make sure you get a jack and cable that will support stereo sound and mic. Here are the ones I used.

Also, if you do manage to mess something up I can send you a pair modded and ready to go for $30(USD)+shipping.
I've been using the ones from Brainwavz for about a year now and they still look like new from my own research some time back these seem to be the ones most people recommend :) https://www.amazon.com/Brainwavz-Philips-Replacement-Earpads-Headphones/dp/B00MFDT894
The most common fix is to get the Fiio BTR5. Its much smaller than a phone and can power an HD 599 no problem; Has a 300 Ohm output too so it's really impressive, albeit a bit pricey.
I got a couple of these for my m40x ... did the trick just fine, and they lock.
ATH-M40X 3.5mm headphone jack adapter
Could probably canabalize for a more robust 2.5mm connection ... or just have 3.5mm on your custom cable and use the adapter as-is.
The only 2 parts are: 1. The female mmcx connectors ... which you won't need if you're going 2-pin amazon.de mmcx connector 2. "Green stuff" epoxy modeling putty / adhesive
Everything else (wires etc) was cannibalized from a define pair of Porta Pros or the KSC75s themselves.
I tried using the original wire too but for some reason couldn't for the life of me get the solder to flow to it. It was my first soldering project so maybe my iron wasn't hot enough but I got these pre-tinned wires and the solder flowed perfectly. The color coding is nice too.
Also I'm using a cheap iron and cheap solder, just make sure it has some flux core like rosin
If I remember correctly these are the ones, of course, it is relatively cheap.
Hi, I'm very interested in modding my KSC75s but I don't want to 3D print the housing component. Most likely, I'll open up the default component like what is done here. That said, how is this guide? This will be the one I plan on using. I've found the MMCX connector and I'm pretty sure it's the right one.
OK, then yeah, that is what you want to combine 2 inputs, and if you want good signal quality on the outputs, then a headphone amp would do the trick. Here are a pair by the same company so they should have a similar form factor. Then just need to add the mess of adapters to go from 3.5mm to 1/4" inch, etc.
You're not wrong, inline mono adapters are hard to come by. You could use a 3 pole and just bridge the tip and middle pin, or use something like this:
If you're local to central FL I'll offer my assistance but don't feel comfortable shipping $420 headphones, and I'm sure you don't feel great about trusting internet randos
Ts100 is pretty cheap and is supposed to work great. There are some mods for it too if your looking for an iron that won't break the bank. https://www.amazon.com/dp/B01MDTO6X7/ref=cm_sw_r_cp_apa_fab_cKgGFbK3BQV61

Just those, pulled apart. I cut off the end I didn't need and stripped enough to solder. Obviously not headphone/speaker wire, so hopefully r/headphones doesn't crucify me, but it's better than killing a driver.
OK, this was a pain in the ass. lol I tried super glue a washer to the jack, but it wasn't quite strong enough. With a little force I could dislodge the washer, and I didn't think it would hold up over time. I had to get a different jack, one that would accommodate a bigger hole.

And if I would have bothered to look up a mod guide for these headphones, it is pretty much the only jack recommended to use because of the issues I ran into. It actually ended up working perfectly, and the fit is so tight no need for any glue or anything.
Thanks for the good info! I actually found exactly what I was looking for on Amazon the other day; a USB Type-C cable that's specifically made for my set of headphones. It has a "digital audio decode module" on it, and is listed as working with Samsung, Huawaii, Motorola, Nexus, etc. so I'm hoping it'll actually work with my phone. I've ordered one, and it should be here in the next few days. Will report back if I have any success :)

I haven't seen a locking 3.5mm, but I also haven't exactly looked too hard. You might consider using the mini xlr socket like in the video, and then using a cable like this one, if you really want locking
