In order to solve the problem of stutter and disconnection of headphones caused by Bluetooth and signal interference, Kirin AI self-developed dual-channel synchronous transmission technology, which can enable two headphones to obtain signals from the left and right channels directly from the mobile phone and communicate directly with the mobile phone.

The main internal components of Kirin A1 chip include AP, RAM, Bluetooth, DSP, sensor matrix, power management module and so on. Kirin A1 chip has an efficient and stable connection and excellent anti-jamming ability. Because it can also provide the fastest Bluetooth transmission speed in real-time, up to 6.5Mbps. The chip can output Bluetooth ultra high definition audio (BT-UHD) up to 2.3 Mbps for optimal sound quality.
