On October 10, 2024, Dou Bao's large-scale model team under ByteDance released the first AI smart body earphones, Ola Friend. Caitong Securities stated that China's Bluetooth earphone market continues to expand at a rate of 20.8%, and AI earphones may be more easily accepted by users. Dou Bao App has a monthly active user base of 32.35 million, leading the domestic AIGC App rankings. The emotional companion intelligent bodies within it account for 43.5%. The distribution of intelligent body types in Dou Bao App may to some extent influence the Ola Friend team's functional positioning of AI earphones, focusing on entertainment and learning features, which may more easily attract existing Dou Bao users to purchase AI earphones.
