High-end headphones (such as the likes of Audeze and HiFiMan) have a such high impedance compared to earbuds. If a neodymium driver of a headphones have a diameter of 40 mm and a thickness (note that this is a flat cylinder) of 2 mm, how much higher is its resistance compared to an earbuds with a diameter of 10 mm and thickness of 1 mm (ρ = 110 x 10^-7 Ωm). Note: I need the answer as soon as possible. Thank you!
