The firmware for your Maxwell can be updated via the Audeze HQ app for PC and Mac.
You can find a current firmware change log here.
Please do not use USB hubs or other secondary connection methods if possible. Plug directly into your computer's motherboard.
If you have updated and need to re-pair your dongle, please see step 4.
Step 1 of 4 - Once you've downloaded and installed the app, open the app and turn on your Maxwell with the dongle plugged in to the computer. The dongle switch should be set to "PC" mode.
The profile should automatically switch to Maxwell if your headset is powered on, but it can be changed to Maxwell via the drop down list in the upper right corner if needed.
Step 2 of 4 - Navigate to the "Settings" tab, and click "Update Dongle" and wait for the firmware to install. Do not unplug the dongle or shut off the headphones until the process has finished.
Step 3 of 4 - Once the Dongle has updated, unplug the dongle from your PC and plug the headphones directly into your PC via the provided USB-C cable. From the Settings tab, click the button that now should say "Update Headset". Do not unplug or shut off the headphones until the process has finished.
Step 4 of 4 - For Firmware v50 or higher, you may need to re-pair your dongle to your headset after firmware installation.
Plug your dongle into your PC or Mac machine.
From the "Settings" tab in the software, you'll see a button that says "Pair Dongle" (if your dongle is already paired and you wish to re-pair it to your headset, you'll have to power your headset OFF before the button will show).
When you click the Pair Dongle button, a new prompt will appear. Follow all on screen instructions to finish dongle pairing.
IMPORTANT NOTE: If you're currently on firmware version 184.108.40.206 or lower, you need to hold down the noise reduction button as you triple-tap the power button to put your headset in pairing mode.
In case the above pairing instructions do not work, you can re-pair using a button on the dongle.
Firmware v46 or lower: Insert a paperclip into the small hold on the side of the dongle until you see the dongle's LED begin to flash. Once the LED is flashing, hold down the noise reduction button on the front of your headset, and then while holding that button down, press the power button three times in quick succession (it may take a few moments for pairing to occur) You'll hear a "pairing" voice prompt.
Firmware v50 or higher: Insert a paperclip into the small hold on the side of your dongle and click the button once. Once the LED begins to flash, triple tap the power button on your headset. You'll hear a "pairing" voice prompt in the headset.
Your headset may power off and power back on after it re-pairs.
Once the update has concluded, power your Maxwell back on and that's it!
