Oh my god I want them. I listen to lots of EDM.
I ordered the TFZ #3 because it supposedly has nice bass. but I don’t know if it’s as much as your graph is showing wow.
can you imagine some nice powerful drum and bass on those. Wow!!!
TFZ No. 3 is my go to basshead IEM for EDM. There are definitely bassier sets out there but the No. 3 has quite good instrument separation/clarity/details for a single DD (best of the single DDs I own). So it is quite good for electronic music IMHO, especially if there are some complex instrumentation or competing intrumentation in the music. With EQ, the TFZ No. 3 can really give jaw rattling headache inducing bass LOL.
I would have considered this set @1clearhead is recommending, but for the non detachable cable. Had a few sets die on me at the cable insertion area, so gotta pass on it unless it's something cheap like a Sony MH755. But it does look super basshead from the FR!
