OPPO AI Heart Ball: 9.8-gram wearable recorder hands-on review
Overview
GeekPark tested the OPPO AI Heart Ball, a 9.8-gram clip-on recorder that starts recording when worn and records up to 24 hours continuously.
The review says it groups related conversations into project timelines, keeps text transcripts without raw audio, and connects to Feishu, WeChat, and MCP-compatible AI tools.
The early version works mainly through the separate Bai Jing AI app and is not yet deeply integrated with the phone system. It supports only OPPO, OnePlus, and Realme phones. OPPO pushed a new firmware and app version on October 11 and says it is still iterating on feedback from early users before launch.
