Ok this is super helpful, and interesting. I have a 23 ultra too.The creative ace 2 connects to my Samsung s23 ultra in LE audio mode. If I turn off LE audio mode in the Bluetooth settings on the phone, it connects in basic aptx. LE audio mode sounds more spatial and refined than aptx mode. Oh and in LE audio mode, the creative app would not connect to the earbuds, have to turn off LE audio mode and the creative app will be able to connect to the earbuds.
Overall, would you recommend?
