Unable to pair Dali IO-4 headphone with my iPhone Air through Bluetooth

I can't pair my headphone (Dali IO-4 with bluetooth 5.0) with my iPhone Air.

The Bose earbuds, from my wife, with bluetooth 5.3 connects without a problem.


I read online that it should be no issue to pair 5.0 with the newer 6.0.


Does someone know the issue?

Thank you for your response. The strange thing was, it can connect to my 'old' Iphone and tested other devices like my wife's phone. I never connected to those devices before, and connected with no problem at all.


But somehow this solved the problem for me.


I connected my headphone with the usb-c cable to my iPhone Air and then turned pairing on. This somehow worked and connected directly to my iPhone Air. Makes no sense to me but maybe it can help someone out if you face the same issue?

Bluetooth 5.0 devices, like your DALI IO-4, should pair just fine with your iPhone, since the standard is backwards compatible. The fact that your wife’s Bose earbuds connect rules out a problem with your phone’s Bluetooth itself. That means the issue is most likely with the pairing state of the headphones or a connection conflict with another device they remember.
