Hi, I'm John! I will help you with this.
Hi, what happens when you try to pair the earbuds?
First, make sure Bluetooth is turned on: Settings > Bluetooth & devices > Bluetooth. Then put the earbuds into pairing mode. Usually, you need to press and hold the power button until the light starts blinking.
After that: Settings > Bluetooth & devices > Add device > Bluetooth. Your earbuds should appear in the list. Click them to connect.
What is the brand/model of the earbuds, and do you get any error message when trying to connect?
