Some pages list the impedance of hd25-1 ii as 70 ohms, others as 65 ohms. The photos show hd25-1 with "70 ohms" written on them. The sennheiser webpage says it's 65 ohms.
The headroom graph shows the impedance is above 80 ohms for HD-25
So what is the real impedance of HD25-1 ii and why some claim a different one?
