1. Are there any cell phones that do not contain child labor (except the fair phone)
2. Are the Huawei freebuds 3i fair trade, if not, are there alternatives?
I think very few headphones are made by child labor, but you can be sure of Teufel
Well, Fairphone also offers headphones: https://shop.fairphone.com/de/accessories/modular-earphones
An alternative to Fairphone would be https://www.shiftphones.com/
What about the huawei freebuds pro?
Think about it for yourself: Fair Trade is an award that allows more people to buy the product. If Huawai had that, they'd advertise it big. If you read AudiFan's article, you would know that almost every cell phone manufacturer uses such dirty methods, with the exception of those that advertise them heavily. (Fair / Shiftphone)
