A delay in audio output may occur during music channel switching or connection snatching in Dual Connection mode. This is due to compatibility issues related to Bluetooth connection priority and Dual Connection functionality on some devices. It's a common issue with over-ear Bluetooth headphones across the market, so doesn't indicate a problem with CMF Headphone Pro.
We recommend directly connecting the headphones to the device you want to use, and closing background audio apps on other connected devices.
