Can't connect to bt le audio only earbuds

Hi there, I bought the Sony Inzone buds, knowing that they weren't advertised as supporting bluetooth, because they only work with le-audio (HFP/A2DP isn't supported).

Here is the output of

btmgmt info

(my adapter supports bluetooth 5.2)

I use pipewire on kde wayland, not pulseaudio - I know that really matters for LE Audio.
Attempting to connect via bluetoothctl results in

1. Stop bluetoothd and start it with -d. Recreate the problem and attach output.
