Anker brings on-device AI to earbuds
Anker Innovations has developed an AI audio chip for earbuds, called Thus, that uses NOR flash memory for compute-in-memory (CIM) processing. This approach supports several million model parameters across multiple workloads and delivers up to 150× more AI computing power for environmental noise cancellation compared with Anker’s previous flagship earphones.
NOR flash-based CIM reduces the required silicon footprint to about one-sixth that of SRAM-based alternatives, making it better suited for highly constrained consumer devices. Anker will integrate Thus into its upcoming Soundcore true wireless earbuds. The company also plans to bring neural-network AI to additional consumer devices, including mobile accessories and IoT devices.
The AI processor’s first disclosed feature, Clear Calls, improves voice clarity on calls by isolating the speaker’s voice from background noise. Unlike conventional environmental noise cancellation, which can struggle in loud environments, it uses an on-device neural network supported by eight MEMS microphones and two bone conduction sensors to separate speech from ambient sound. The result is clearer calls in challenging environments such as airports, bars, and busy streets.
Full product details will be announced at Anker Day on May 21, 2026, in New York.
