I live in the UAE, and at a market I found a stall, that sells phone speaker amplifiers by Mangobeat made entirely of wood, from old mango trees that no longer produce fruit.
They work completely independent of electricity and you can just pop any phone in there and they’re also so beautiful!
They weren’t overpriced and it was just amazing to see someone making something like that out here, bringing in an environmentally friendly alternative that’s much needed in this side of the world.
