Hello,

I was hoping you all would be able to help me out in relation to a question I have about 'nominal impedance'. Currently, I have a set of Sennheiser HD515 which has a 'nominal impedance' of 50 Ohm. I am looking to upgrade to a set of Sennheiser HD650 which has a 'nominal impedance' of 300 Ohm.

What exactly does the 'nominal impedance' affect? I have tried reading around about this, and it appears that the impedance is alternative resistance. I have no idea how this applies to headphones!

Any help will be greatly appreciated on this matter.

Thanks.
