Through acoustic testing, the research team identified a narrow frequency band – a “safety gap” – capable of penetrating ANC headphone filters. This range lies between 750 and 780 Hz.
Building an entire product around EQ crossover frequencies (which are not standardized or regulated in any way) seems a bit risky to me. Those are things that could change at any time, as could the shapes of the EQ curves themselves. there are fads in engineering design like anything else and in this wholly digital era they tend to cycle and proliferate faster because increased performance (or at least hte temporary consumer perception of such ) is only a software update away. People are extraordinarily susceptible to placebo effects in the audio realm (probably because most people prioritize their visual sense), so just moving EQ crossovers around or making them dynamically adjustable is an easy path to consumer buzz. You see this all the time with pro audio plugins.
