If your phone is capable of reverse wireless charging, it will charge your earbuds from your phone battery.
To get it to work, you will need to buy some Magsafe magnets online (something like these: https://www.amazon.com/12Pcs-Magsafe-Rings-Conversion-Accessories/dp/B0C7H5T1D2/ref=asc_df_B0C7H5T1D2/?tag=hyprod-20&linkCode=df0&hvadid=693712892605&hvpos=&hvnetw=g&hvrand=12580044963273930130&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9021731&hvtargid=pla-2202499384006&psc=1&mcid=73af4f48f4903e30a8134e13410088a9&gad_source=1&gclid=CjwKCAjwrcKxBhBMEiwAIVF8rEVpncQwyWdBfzuiveR5APM4PgCkGsT3Rd9QmkoCsXY6p_RLlmod8BoCQwEQAvD_BwE https://www.ebay.com/itm/315279811312?chn=ps&var=613749414209&_trkparms=ispr%3D1&amdata=enc%3A1bGTz83hfRzCLDGz8I9qBRA57&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&mkscid=101&itemid=613749414209_315279811312&targetid=1584739237574&device=c&mktype=pla&googleloc=9021731&poi=&campaignid=19894961968&mkgroupid=148855406073&rlsatarget=pla-1584739237574&abcId=9307911&merchantid=5338898190&gad_source=1&gclid=CjwKCAjwrcKxBhBMEiwAIVF8rA_u5dvzWnt74-MmSMr2dW3opvmguP1YaU46ITb7U6ohBXa228D1txoCVtoQAvD_BwE ), stop the print at the appropriate time, insert them, and continue the print.
