For example, for the delay problem of wireless headphones, the Kirin A1 chip uses a self-developed dual-channel transmission technology. So the two headphones obtain the left and right channel signals directly from the smartphone side. And they directly communicate with the phone to avoid interference. Apart from this, not only the power consumption is 30% lower than other TWS wireless headphones but the delay can be as low as 190ms. Ultra-low delay is very important for games. So now, you can experience real-time synchronization of audio and video.
In addition, the Kirin A1 uses the unique BT-UHD ultra-high-definition Bluetooth codec technology. Due to it, the maximum transmission bandwidth can be up to 6.5Mbps. This greatly improves the transmission speed, which is 2.8 times the transmission speed of the Bluetooth standard (2.1Mbps).
