Re: NC 700 Switching between devices
After some frustration, I've been able to get device switching working by changing which NC700 BT device I paired to. During my troubleshooting, I noticed that sometimes when pairing the headphones I would only see the low energy BT device (device name is prefixed by "LE-") and other times I would see a standard "NC700" BT device.
I use my NC700 headphones with my Windows 10 PC and iPhone 11, originally when I first paired the headphones I paired my PC and phone to the low energy (LE-) NC700 device because it was the first device to be displayed. I didn't think anything of it at the time but I found that getting the headphones to seamlessly switch between PC and phone was a nightmare using the low energy BT device.
After clearing the bluetooth list of devices from the headphones and then re-pairing to the standard NC700 BT device, I've found that the device switching is now working well. I had to remove/forget the "LE" device on my PC and phone, I also had to uninstall the LE device in device manager on Windows 10 before I could connect to the standard device and get device switching working.
Worth a try if you're having this problem...
