Quote:   SNR: The inductor induced 0.5db loss which is quite insignificant considering the headphones' sensitivity. This loss would affect the both the 'signal' and 'noise' so SNR would be the same.   THD: This is quite a meaningless number by itself. I have a full plot of...

It turns out that the headphone can be equalised with passive EQ. This makes things very easy.   http://gainphile.blogspot.com.au/2012/05/audio-technica-ath-ad700-correction-eq.html  

Quote:   Thanks. I have not considered HRTF, just a mere correction of Frequency Response. I'm pretty new at this.   But for sure HRTF and also Equal Loudness Contour plays a big part on how the sound is perceived. Not exactly an easy subject to tackle at once too !    I'm...

Quote:   This was my first time of measuring headphones, and I must admit I did not expect such non-flat response above 1khz.   However a quick glance to other independent measurements it seems this is quite normal. Perhaps due to them being basically 2" fullrange speakers with...

I'm discovering a new world of headphones. My ATH-AD700 arrived today    This is the raw measurement data of the headphones:         And after EQ:     These are temporary notch filters while I'm planning to build a headphone amp (any recommendations?). But they're...
