iPad Pro doesn’t find any Bluetooth devices

I would guess you are not using the proper pairing method, which would be provided by B&W (jealous btw., B&W makes wonderful speakers and headphones).

Read the user guide or if B&W didn't provide a user guide, go out to their website and download the user guide for your headphones.

I am using the correct pairing method for my Dutison V4.2 single earpiece because I can connect with my iPhone but my iPad just gives me the spinning circle and does not detect the device in "other devices."

Is the iPhone the single earpiece is paired with nearby and powered on when you are trying to pair it with your iPad? If it is, it won't likely be seen by the iPad as it's already paired with iPhone. Try turning Bluetooth off on the iPhone, then try to pair it with your iPad.

Hello,

More than likely the headphones need to be put in a pairing mode. I suggest consulting its user manual for assistance.

That works. I thought I could pair with both because it paired with my phone & my MacBook at the same time and with 2 iPhones with different numbers. Thank you!

Glad you got it connected. You're most welcome!
