A few random notes:

- Your model neglects the charging case with its own battery and microcontroller.

- A Trsla is more likely to be recycled properly than the same amount of earbuds. Itbis also more recycleable because ofnthe high amount of steel and other bulk materials in it.

- The ratio of semiconductor electronics to total weight is extremely different between the two products. And semiconductor manufacturing is extremely resource intensive. All we typically see is squeaky clean neon lit clean rooms, which belie the use of high amounts of aggressive and toxic chemicals that have to be produced somewhere and generate waste that is never talked about.
