Yeah, I'm not sure why they put that so prominently, when what they're actually saying is that this is a different take from the common balanced tuning.
First paragraph of text says this: "In today's audio landscape, balanced tuning in in-ear monitors (IEMs) may seem ubiquitous. However, the Dunu Mirai takes a divergent approach. Synonymous with its name, Mirai is intended to encapsulate the type of sound that the market might be more open to in the future—except you get to hear it now."
What the fuck happened. I refreshed exactly when the timer hit 0 and the MM-500 were already sold out.
