Connecting (Bluetooth pairing) Bowers and Wilkins PX headphones to your iPhone

I had a problem with connecting my B&W PX headphones to my new iPhone 12.

The solution is to read the B&W manual *very* carefully to follow the pairing instruction for a new device. The guidance is to *press* (not slide) the button used for on/off/bluetooth.

As your general usage of this button is to slide it forwards and backwards to turn the headphones on and off, it may not be clear that you can also Press (in) this button, which is what is required for pairing. So, press in, hold for a second, and the headphones will start pairing.

Hope this helps.
