Pairing the Maxwell dongle to your headset is simple.
First, download and install the Audeze HQ software for Mac or Windows (beta v78 or higher) and plug your new dongle into your PC or Mac.
Open the Audeze HQ software, and from the "Settings" tab in the software, you'll see a button that says "Pair Dongle" (if your dongle is already paired 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 188.8.131.52 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 v48 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.
