The Fostex TH-610 was the first (I think) of several high-end headphones with a remarkably similar frequency response. Some are sold for 300, others are sold for like 1500. It is a good headphone, dont get me wrong.
I am talking about the
Fostex TH900,
Fostex TH909,
E-Mu Teak,
Denon AH-5200,
Denon AH-7200,
Denon AH-9200.
So I began to wonder if these all contain the same drivers and just slightly differently pads & damping, because that is what it looks like. The bass and the treble response always looks almost exactly the same. Differences mainly occur around 1k and in the upper treble, and even there there are certain parellels when it comes to the positions of their peaks & dips.
Besides, also the design of these headphones are very similar. Sometimes the cups are bamboo, sometimes they are Teak, but..
I normalized the frequency response down below on 5000hz in order to make the similarities clearer.
