The Qi Coil™️ was plugged into the phone - I didn't hear any sound.Updated 8 months ago

Qi Coils do not produce sound when plugged into your mobile device. However, if you wish to experience sound therapy in conjunction with magnetic energy therapy, you can use a splitter to combine the use of headphones or speakers. This allows you to simultaneously hear the frequencies for sound therapy while benefiting from the Qi coils' magnetic energy therapy. For more details on this advanced setup, please refer to the video tutorial here.
