Will my wireless mic work on other devices like iphones or Oppo, Vivo, Samsung, Oneplus or Redme?

For apple devices, relevant OTG converters will have to be purchased separately, not provided in the box. For Type- C phones, cable is provided in the box that ensures the compatibility with the phones with Type C connection but it may not happen in some devices after recent software updates. Try downloading the external apps in such cases like Open camera/ HD camera.
