I had some HD 25's arrive today, and discovered that they aren't HD 25 1-II, but HD 25 II (without the 1).
The box has HD25 II on it, and they do not have a right angle cord. The left headphone has got "HD 25 II" printed on it, with 70Ω underneath. I understand that the 1-II has "HD 25-1 II" printed on it - which makes me think there might be an electronic difference
I've had a google and a search on here, but can't find much, Can anyone tell me the differences between the units please, I'm not sure whether or not to return them. Thanks.
