Why does it take a while for my headphones to output sound after connecting to a device?

Due to compatibility issues related to Bluetooth connection priority and dual connection functionality on some devices, a delay in audio output may occur during music channel switching or connection snatching in dual connection mode. This is a common issue that may affect over-ear Bluetooth headphones across the market. We recommend directly connecting the headphones to the device you want to use, and closing background audio apps on other connected devices. This is not a fault with the headphones—please feel assured in using them.
