The cans The rig FR TH-X00 dist D7000 dist Step IR TH-X00 decay D7000 decay TH-X00 waterfall D7000 waterfall I have been measuring bunch of my headphones now that I got a setup that is pretty consistent. I just got the fostex this week and I figured I would post what I got. The thx00 have around 30hrs on them and the d7000 have unknown amount of hrs on them. It was much easier to get a good seal with the denons because of the pads, the opening is larger and the pads are softer(probably from use). The measurements above are the best of many, many measurements taken using 128k length with 8 sweeps per run. I am very new to the measuring process so any advice for improving future measurements or postings is welcome.
