This is very frustrating indeed. However, I confirmed that Samsung Galaxy Z Flip 7 running latest Android 16 can pair with Oakley Meta HSTN. It seemed the Sony failed to respond to Meta AI App's requests to control the speaker volume via Bluetooth right after successful Bluetooth pairing, and Meta AI App could not handle that error and failed the pairing process. At this point, the AI glasses had paired with the Xperia over Bluetooth as a headset; yet the Meta AI App had not registered it as a Meta AI device. I wish I could find a way to contact someone from Sony or Meta to assist with debugging that handshaking.
