Step 1: Find Bluetooth icon in the taskbar and go to ‘‘Add a Bluetooth device’’. Click “Add Bluetooth or other device” > “Bluetooth”
Step 2: Put your Headphones/Speakers into Bluetooth Pairing Mode.
Headphone / Speaker 1st-Time Use: The Headphone/Speaker should enter pairing mode automatically when powered on.

Sony, Bose, Jabra, Apple, Beats, Google, Sennheiser, Amazon Echo, JBL, Philips, Panasonic, Audio Technica, Bang Olufsen, Skullcandy, Bowers & Wilkins
