I think the Kirin A1 is better. The chip measures 4.3mm x 4.4mm and integrates a Bluetooth processing unit, an audio processing unit, a low-power application processor and a separate power management unit. The Kirin A1 uses BT-UHD Bluetooth codec technology with a maximum transmission bandwidth of 6.5 Mbps. Pretty good
