Look at the first few pictures of this thread to get an idea of how boosted the upper mids are, at least to the average ear.
However, I was not able to EQ the K701 to my liking. Too much equalizing and too many bars for my liking.
I don't think tonal balance plays a part in either of the issues that have come up.
One of the reasons I find the AKG K 702s to be so good for me is that they do not have the warmth that unfortunately so many pieces of hi fi equipment come with.
This warmth with those other headphones and amplifiers is not due to a particular tonal balance but other issues.
Instruments at the far end of the treble spectrum can play warm and cold sounds and great musicians can exploit these abilities.
The other issue which has arisen is the AKG K 702 flaw which is that they can misbehave on treble. I write can, because in fact the AKG K 702 are most of the time truly superb on treble.
This misbehaviour is not about tonal balance but rather I think it is that if they are supplied without enough information, then they seem to have a tendency to lose control at the top end.
It is why I think that very good amplifiers can greatly improve this aspect of the AKG K 702s.
