For anyone with connection issues w/ bowers and wilkins wireless read this.
The first device the P7's are paired with will be the headphones primary connection. Primary connected devices will pair automatically when both the headphones and devices are turned on with Bluetooth active.
If you have recently purchased a new phone X, unless you have cleared the pairing history on the P7 wireless, the new connection will be deemed a secondary connection. Secondary connected devices do not connect automatically and will need to be connected manually via the Bluetooth menu on the source device.
If you clear the pairing history on the P7 headphones by holding down the volume - and Bluetooth pairing button at the same time, and forget any previous pairings on the iPhone X, you can then set up a new primary connection with the iPhone X.
When set up as a primary connected device, the P7's with connect automatically when both them and the iPhone X are turned on with Bluetooth active.
Kind regards,
