I own 1060C, TH-X00 PH, and HE-400i. For R&B, Hip Hop, Rock, and EDM for a semi-basshead, the TH-X00 is superior due to the quality and quantity of the bass. The other two are not in the same ballpark for bass (the 1060C may have a tiny bit more texture). Frankly, for R&B, Hip Hop, and EDM, everything about the TH-X00 is at least very good and the TH-X00 has very fun tuning overall without being fatiguing.
M1060C may be better for Soul and Jazz, especially with female vocals.
My biggest issue with the M1060C is the lack of response to EQ using a Loki. For some reason, even cranking the 20hz knob all the way just doesn't deliver. When using a Loki, I'd say the HE-400i could even be better for borderline basshead than the M1060C. That said, I do really like the M1060C for more tranquil music or anything where I want the vocals to soar (though my Elex are a better option overall for those songs).
