It has been about two weeks since Huawei unveiled Watch GT 2 smartwatch and Freebuds 3 wireless earbuds. Both these devices have one thing in common and it is the use of Kirin A1 processor. This is Huawei's new processor meant specifically for wearables and earbuds and now for the first time, it has shared technical details about the same.
The Huawei Kirin A1 is claimed to be the world's first wearable chip with support for Bluetooth 5.1 and Bluetooth Low Energy 5.1 aka BLE 5.1. This is one of the reasons that this single chipset is capable of supporting wearable devices as well as wireless earphones. It has a dedicated and "powerful" audio processing unit to help deliver a great audio listening experience.
The chipset features Huawei's own dual-channel synchronous transmission technology to reduce audio latency. It helps in keeping the video and audio synchronized which is specifically beneficial during gaming sessions. It will also be helpful in areas like shopping malls and airports where users usually experience interference because of WiFi and Bluetooth frequencies getting overlapped.
This new Kirin A1 chip measures only 4.3 x 4.4 mm and comes with efficient power management support. It means your wearables and earbuds powered by this processor should last more while performing at a higher level at the same time. It is capable of offering Bluetooth transfer speed up to 6.5 Mbps which is significantly higher than previously offered 2.1 Mbps speed. The good thing for audiophiles is that the processor comes with lossless audio (FLAC) support from CD level and Hi-Res audio sources.
