As these are personal care electronic devices, they must adhere to strict safety standards. Ensure the product has FDA (USA), CE (Europe), and RoHS (Hazardous Substances) certifications. Since the device connects via Wi-Fi or Bluetooth, FCC (USA) or RED (Europe) wireless certifications are mandatory. Furthermore, the ear picks should be made of medical-grade silicone or PC material to prevent scratching the ear canal, and the device should have an IP67 waterproof rating for easy disinfection with alcohol.
