Well, I can recommend the soundcore anker life A1 earbuds for swimming, and the soundcore sleep A20 for low profile earbuds that dont stick out of your ear. Went through atleast 4 sets (wired and wireless) of earbuds for each until settling on these.
Still would only be 100% profit. Costed nothing to get them, so when you sell them, they will be 100% profit.
