Use DG40s with Bluetooth Headphones / Speaker
Step 1: Get your Bluetooth headphones/speakers into pairing mode
Headphone / Speaker 1st-Time Use: The Headphone/Speaker should enter pairing mode automatically when powered on.
Note 1.1 :Non-1st-Time Use: Merely powering on WILL NOT get it into pairing mode, you'll need to do so manually. Please either refer to the brand list below or refer to your Headphone/Speaker's user manual. You also can search on Google. E.g. “Bose QC35 Bluetooth Pairing Mode”
Sony, Bose, Jabra, Apple, Beats, Google, Sennheiser, Amazon Echo, JBL, Philips, Panasonic, Audio Technica, Bang Olufsen, Skullcandy, Bowers & Wilkins
Note 1.2 Most Bluetooth headphones / speakers connect to one device at a time. So you are recommended to TURN OFF Bluetooth function on your mobile phone / tablet if they are previously paired with your headphone / speaker.
