How to Pair/Sync Audecom 2800 Bluetooth Headset

Audecom is no longer around, and I recently replaced my old phone and needed to pair it with my new device.
Turns out the instructions are only in a few odd places on the internet, so reposting the instructions for anyone who needed it.

1) Press and hold the “talk” button for 10 seconds, until the lights blink the 2 different colors (red and blue for me)
2) When pairing it, use code 1234

Simple instructions, but not so simple when you don’t know how it pairs at all.
