Hi Brandon, I am John J.D., a fellow Microsoft user like you.
I understand your frustration, and I'm here to help. Thank you for sharing what you have tried so far.
Please try the following steps to manually search for your Beats Solo 3 Headphones in the Bluetooth settings and make sure they are in pairing mode:
> Turn off the Bluetooth on all other devices, including your iPhone, and just keep the Bluetooth on your headphones and laptop turned on.
> In your laptop, go to Settings > Bluetooth & Devices.
> Ensure Bluetooth is turned on.
> Click "View more devices" > "Add device."
> Select "Bluetooth."
> On your Beats Solo 3 Headphones, press the power button for 5 seconds. Make sure the light indicator is blinking to put it in pairing mode.
> Wait for the scan to complete and look for your device in the list. Ensure it’s within range.
> Select your Beats Solo 3 Headphones to pair them.
