The metal shell is copper with nickel plating, passing a 48-hour salt spray test. Compared to the 6mm circular version, this model maintains a similar projected area while offering superior direction recognition and layout flexibility, making it an ideal choice for smart rings, micro TWS earphones, medical patches, AR glasses temples, and precision sensors.
