UGREEN's own product information confirms the three operating modes, CSR8675 chipset, 1200 mAh battery, Bluetooth 5.0, and support for aptX/aptX LL/aptX HD.
Note: Some retailers list the battery as 1000 mAh, while other listings and UGREEN's product information list 1200 mAh. For the CM433/20140, I would treat 1200 mAh (3.7 V, 4.44 Wh) as the better-supported specification. igadgetbd.com
