This graph? Only V3 but whatever
Let's see
FR graph doesn't tell EVERYTHING of a set of headphones. For example, the KRK 8400's have also a nice looking low frequency line but are bass shy in terms of impact but do have good extension. These have a good bass extension from the looks of it, how it plays out with impact, tightness, speed, clarity and other factors are unknown. however it does seem "bassy" with good extension and pronuncation. Seem that is.
There seems to be a slight dip in the lower mids or upper lows which may(MAY) lead to a weaker upper bass responce or vocals or mids that don't have an as much pronounced low end(depends on your tastes).
At 1K to 5K it does have a nice hump which MAY indicate forward and more pronounced vocal. The qualities, speeds and other stuff again are unknown. The overall headphone sound signature may be guessed though
The graph ends at 9K with no indication past that with numbers so I am not sure if that dip PAST 9K should be accoutned for as a dip in the upper mids or something else. There isn't a V dip at 5k-7k which does signify that it isn't a dubstepy headphone.
There are no numbers past 9k but it doesn't seem to be a "bright" or high section that goes really high past that. For example, the HD800's have a nice spike at around 12k which is quite renowned.
Overall without knowing anything, I would say its a nice recoding, mixing and pleasureable to listen to CIEM as it has a good bass F responce, and well placed forward mids that I like.
There are no numbers past 9k, so I do not know if that drop off to 0 at the very end should be taken as a drop off before the 20k to 22k human barrier or what not.
