Well, assuming that the T1.2 has more bass and less treble than the T1.1, it should resemble more similarly to the DT880 as shown in this graph:...
Hmm, I've never tried the T1.2, but I've listened to the DT880 which is also semi-open and roughly measured the same, and I never had the same...
What was your issue with them?
Are these measurements raw, or compensated?
I understand that. My english is not that good. This site has it done using a 500Hz sine wave input: http://www.headphone.com/pages/build-a-graph...
@purrin What input (in Hz) do you use to measure your distortion readings?
I wonder what the soundsignature curve looks like for the new T5p.
