It's more about sensitivity than impedance. Actually, I would be rather worried about impedance being too low than too high. Most motherboards die at low impedances (below 32Ω). But if that was the case, you can always get a $10 Apple dongle. For high impedances, the headphone would also need to be inefficient which is rare at high impedances. Such examples are DT880/990. But for example, I have no issues driving a 470Ω R70X off my motherboard. Of course, I don't know what is your laptop's motherboard capable of, I'm just trying to help you understand that you don't necessarily need 32Ω. For example, I'm certain you would have no issues driving a 150Ω 660S off any motherboard.
