Capitalism, Scams and Headphones
What you see in the picture illustrates a scam. You may not be interested in Headphones, or Frequency Response Graphs, but the principle here is cross applicable. So just consider the following. Let me keep it simple. AKG produced the k601 some years ago, with an MSRP of $300usd. Then, after a while, it discontinued it. You know why? Because the quality of these phones is similar to high end models now being sold at more than a thousand US dollars (click image above for a clearer view of the similarity between the $300usd k601 and the $2000usd Audeze LCD X). So AKG realised that they were selling us real quality at a relatively low price with the K601. Now, even for the best AKG headphones, like the K712 or K812, the latter of which costs more than a thousand dollars (approx: $1500usd), you can't get the quality o f the k601 in terms of frequency response curves. (click image below. The $1500usd K812 is only slightly better only at the 1-3khz region....
