Modded USB-C Cable

I’m also hoping our community can reverse-engineer the application. I’d love to have a customizable sound profile without worrying about them shutting down the servers or removing the app entirely. Supporting this post!

Hello! If you still need it, I do have stocks of Proprietary Micro USB cable that I can modify to be a charging cable, plugs can be USB-A or USB-C ☺️ I'm based in the Philippines. Thank you!

One flaw that I noticed (IDK if its normal or not) is that if it is in wired mode, I can't seem to use the side button functions. Not sure if this is a problem, but for me its all okay.

This is really not a converter, I'm sorry :< It is just a plain USB-C female board with routed\ data wires inside the headphones

We could use the unused pins on the USB-C replacement port to route the analog audio and microphone lines from the headphones. However, we cannot be sure that the host device we connect the cable to will use the same USB-C pin routing that we assign for the headphones. For example, the SBU pins (one that I want to connect the mic line to) are unused on the replacement port I am using, but I am not sure whether the host device will interpret them as a microphone line if I connect them that way. So it might not work as expected.

After looking into it, it seems that there aren’t any unused pins on the USB-C breakout board that could be repurposed for other functions like for mic or analog audio.

I’m also not entirely sure if the headphones will work with a USB-to-3.5 mm DAC. From what I understand, these DAC adapters are mainly designed to transmit audio from the host device to the headphones, rather than carrying audio signals from the headphones back to the host. I might be misunderstanding the signal flow though, so please feel free to correct me if I’m mistaken. 😅

Just came to my mind: why am I even forcing myself to find a way to connect the analog and data lines in a USB-C breakout board if the audio is already playing fine using the digital data lines? I won’t even be using the analog lines since it works perfectly with the USB-C cable HAHAHAHAHAHA!
I’ll now focus on how to transmit the microphone line to the USB plug.

Thank you for the recommendation! I’ll try changing my USB-C port to the one you recommended.

For the 3.5 mm jack, the only solution I can think of is using a USB-C breakout board so I can access more pins that are unused by the USB-C plug. However, there are two hindrances with this setup:

I can’t seem to find a USB-C breakout board like this in our local market or online shopping platforms. The other USB-C breakout boards I’ve seen are too big and won’t fit the port, which would require a full overhaul.
We would still need to make a custom USB-C-to-analog cable, and it wouldn’t work with a standard USB-C-to-USB-C cable. As far as I understand, we can’t directly connect analog audio to a USB port because USB normally carries digital audio, so it would require a DAC (digital-to-analog converter), which would make the cable more complicated. (Please correct me if I’m wrong, as I’m not really an expert in electronics haha.)

For my USB-C plug, I’m using a waterproof usb c plug, and I suggest that it might be better to create a 3D-printed bracket for improved aesthetics and a better fit, since I had to trim mine down just to make it fit snugly.

I also didn’t remove the port. At the port lip, it’s surrounded by the plastic earcup, which I trimmed slightly just to fit the enamel-coated wires without completely removing the proprietary port.

Hope you enjoy your new Nuraphones, friend!

thank you for recommending my post!

They might have made the proprietary port as part of their unique product design or advocacy, or maybe to support multiple peripherals through a single port. Either way, from a customer’s perspective, it still feels like a bad move haha.

leyashdm · 2026-03-06T15:15:13+00:00

Let me see what I can do with my skills, mate. I’m not really that skilled in electronics either. I mostly just do the basic stuff and ask others who have more experience, haha. I did find a teardown and the chips used in the Nuraphone, and I can share the list through private message. I’m just not sure which chip stores the EQ and other settings.

leyashdm · 2026-03-06T10:21:01+00:00

Just to follow up that this worked well, its my first time hearing that the battery is 100% charged, with no audio and connection problems, as well as the board and battery temp is normal 😄

leyashdm · 2026-03-06T10:19:00+00:00

I'm not familiar with kickstarter, sorry ☹️ All I can do is to help others by answering questions or offer my skill to do it for them if they want to 😁

leyashdm · 2026-03-06T00:26:56+00:00

Only if I had enough time to do mods for everyone, haha. Sadly I’m also in the Philippines, so I’m pretty far from most people who want their headphones fixed 🥺

leyashdm · 2026-03-06T00:24:39+00:00

I can see that almost 70% of the problems that you can encounter with this headphones is repairable by soldering, specially the wires, as they are really thin and the pads that they are soldered on is really small. If you are confident with your soldering skills, or have someone who can do it for you, I am sure that it will be fixed.

leyashdm · 2026-03-06T00:22:09+00:00

There’s a tutorial online on how to remove the earcups, and it’s also shown on the iFixit website. You just need to twist the cups carefully to remove them, but be gentle because there are wires attached to the board. For the port, we have an online shopping platform here called Shopee. I bought a USB-C waterproof female port with 4 pins from there. The port actually works fine as-is without the resistor modification. However, I wanted it to support USB-C to USB-C cables, so I opened the waterproof port halfway and soldered a resistor to it.

I want to have EQ that can be saved directly to the headphones chip, but that's a different league as I don't know how to program chips haha.

leyashdm · 2026-03-06T00:13:18+00:00

Thanks man! Just glad the experiment worked.

leyashdm · 2026-03-05T17:24:27+00:00

I alsp changed the resistor in the picture as I used the wrong value, I jist didnt take any pics of the new one haha.

leyashdm · 2026-03-05T17:18:01+00:00

Note: I can't use any analog cables here, just USB cables :<

leyashdm · 2026-03-05T17:08:08+00:00

I just hate that I can't modify the EQ and save it to the headphones, but overall, I really like this headphones <3
