How I Upgraded My SteelSeries Arctis 7 (PS5) from Micro-USB to USB-C
>
Why I Did This Upgrade
The SteelSeries Arctis 7 is still one of my favorite gaming headsets. The only thing that always bothered me was the outdated Micro-USB charging port. After years of plugging and unplugging the cable, Micro-USB connectors tend to become loose or fail.
Instead of replacing the headset, I decided to upgrade it to USB-C.
The good news is:
It works!
The headset charges perfectly through USB-C, and now I don't have to keep a Micro-USB cable around just for this headset.
Parts & Tools
Required
- USB-C 5-Pin Replacement Board
- Hot Air Rework Station / Heat Gun
- Fine Tip Soldering Iron
- Electronics Solder
- Flux
- Solder Wick (Desoldering Braid)
- Torx T5 Screwdriver
- Hot Glue Gun
- Dremel or Rotary Tool
Optional—but Highly Recommended
- Digital Microscope
- Magnifying Goggles
If I were doing this repair again, I would absolutely buy a digital microscope.
The solder pads are incredibly tiny.
I originally used magnifying goggles and my phone's camera, and while they worked, I honestly believe a digital microscope would have made the repair much easier and given me much more confidence that every pin was soldered correctly.
Step 1 – Open the Headset
The charging port is located inside the left earcup.
Using a Torx T5 screwdriver, carefully remove the screws and open the headset.
Take your time and keep track of every screw during disassembly.
Step 2 – Remove the Original Micro-USB Port
Apply plenty of flux around the Micro-USB connector.
Using your hot air rework station, evenly heat the connector until the solder melts.
Once the solder has fully melted, carefully lift the connector off the board.
Do not force it.
After removing the connector:
- Clean the pads using solder wick.
- Remove any excess solder.
- Clean the PCB thoroughly.
Step 3 – Tin the Pads
One trick that helped me tremendously was pre-tinning everything.
First, apply flux.
Then, using your soldering iron, lightly add fresh solder to every pad on the headset PCB.
Next, repeat the same process on the USB-C adapter board.
Having solder already on both surfaces makes the final soldering process much easier.
Step 4 – USB-C Orientation
This is probably the most important part of the entire project.
The USB-C board I used has six pins on the connector itself but exposes only five output pins, so you don't have to add jumper wires or perform any additional wiring.
Simply align the adapter correctly.
The positive side should face the edge of the PCB.
See the USB-C orientation diagram included with this guide for the correct alignment.
Step 5 – Solder the USB-C Board
Carefully position the USB-C adapter.
Apply plenty of flux.
Using your soldering iron, gently drag the tip from one side of the pins to the other.
Because both surfaces were already pre-tinned, the solder flowed together very easily.
Take your time.
Inspect every solder joint before moving on.
How I Checked My Work
This is where I learned one of the biggest lessons during this repair.
I originally used magnifying goggles while soldering.
Then I switched to my phone's camera.
I used Live View to inspect every solder joint.
After that, I took high-resolution photos and zoomed in to verify that each pin was actually making proper contact.
That method worked surprisingly well.
However, if I were doing this repair again, I would absolutely use a digital microscope.
The solder joints are simply too small to inspect comfortably, and having a microscope would make the process much easier.
Step 6 – Test Everything Before Gluing
This step is extremely important.
Before applying any hot glue:
- Plug in a USB-C cable.
- Verify the headset charges correctly.
- Verify the connector is aligned.
- Verify nothing moves.
- Verify every solder joint is working properly.
Only after I confirmed the headset was charging correctly did I permanently secure everything.
If something isn't working, now is the time to fix it—not after everything has been glued together.
Step 7 – Modify the Plastic Housing
The original Micro-USB opening is too small for a USB-C connector.
Using a Dremel, slowly enlarge the opening until the USB-C connector fits comfortably.
Go slowly.
Remove only a small amount of plastic at a time.
Test-fit the connector often.
Step 8 – Reinforce the Connector
Once everything was working perfectly, I applied hot glue around the USB-C adapter.
Then I carefully installed it back into the headset housing.
One challenge is getting everything aligned while fitting it back into place.
What worked best for me was:
- Solder the USB-C adapter first.
- Position the connector through the opening.
- Carefully shimmy and wiggle everything into place.
- Once I was satisfied with the alignment, reinforce it with hot glue.
After reassembling the headset, I added another layer of hot glue from the outside for additional strength.
Why I Added Hot Glue
The biggest weakness of charging ports isn't usually the connector itself.
It's the repeated mechanical force from plugging in the charging cable hundreds or even thousands of times.
Every time you insert the cable, you're placing stress on the solder joints and PCB.
Eventually, those joints can crack.
The hot glue acts as strain relief, helping absorb that force instead of transferring it directly to the circuit board.
Hopefully, this modification will last for many years.
An Alternative Design
Years ago, HP laptops had a similar problem.
People constantly damaged the charging port because it was soldered directly to the motherboard.
HP eventually redesigned the system.
Instead of mounting the charging connector directly to the motherboard, they attached it using a short cable.
That way, mechanical stress wasn't transferred directly to the motherboard.
You could apply the same concept here if you're comfortable with more advanced electronics work.
Instead of mounting the USB-C adapter directly to the PCB, you could connect it using short wires and mount the charging port elsewhere inside the headset.
This isn't necessary, but it's another option if you want maximum durability.
Tips I Learned
✔ Use plenty of flux.
✔ Pre-tin both the headset PCB and the USB-C adapter.
✔ Don't rush.
✔ A digital microscope is worth the investment.
✔ Your phone's camera works surprisingly well for inspecting solder joints.
✔ Test charging before applying hot glue.
✔ Go slowly when enlarging the opening with the Dremel.
✔ Reinforce the connector with hot glue so the PCB isn't absorbing all of the mechanical stress.
Future Project
Now that this upgrade was successful, my next project is converting my Bose SoundLink speaker from Micro-USB to USB-C using the same general method.
I'll likely use many of the same tools and techniques from this guide.
Credits
A huge thank you to everyone in the electronics repair community who shared wiring diagrams, photos, videos, and tutorials. Those resources helped me understand the USB-C pin orientation and gave me the confidence to complete this project successfully.
If you're attempting this modification yourself, I highly recommend reviewing multiple guides before starting.

Final Thoughts
This isn't the easiest modification I've ever done, but it's definitely one of the most satisfying. The SteelSeries Arctis 7 is still an excellent headset, and upgrading it to USB-C gives it a much more modern feel while eliminating one of its weakest design points.
If you're comfortable with fine-pitch soldering, have the right tools, and take your time, this is a very rewarding upgrade that can help extend the life of your headset for years to come.
I hope this guide helps someone else breathe new life into their Arctis 7. Happy soldering!
