Sounds interesting, so I did some Googling:
Diffuse Field Frequency Response equalised headphones seems to mean you
get
the same perceived frequency response from your headphones compared with
your loudspeakers in a room. If they weren't equalised you'd perceive a
different frequency response as the reflections/obstructions between the
source and ear canal are different in each case.
For more detail, I found this reference which explains it clearly and
simply
and points out there is a lot of room for marketing specmanship dealing
with
headphones: http://headroom.headphone.com/pdfs/June2001.pdf
Thanks for the info. - seems to be a strange concept, in terms of true high
fidelity, if accuracy is the goal; I would have thought that the main
advantage of headphones is the lack of room interaction which then allows
you to engineer as flat a response as is technically possible to achieve in
an effort to attain accurate reproduction - I guess the answer is that
accuracy is not the goal, and that making headphones sound like speakers
s - entirely valid if that's what a particular end user wishes, but it
doesn't seem to be high fidelity ?? Does this mean that all headphones which
have a DFFR are inaccurate?
I suggest you audition some. Remember to cover your hair with gel first

Cheers.

With reference to headphone design, what is a 'Diffuse Field Frequency
Response' ?
TIA.
