Hey everyone, I recently released my first collaboration IEM, the DUNU Mirai, so I thought it’d be a fun opportunity to answer some questions about what shaped its development. I’ll also be happy to take questions about anything else pertaining to audio!
So I think a lot of people were expecting a 64A-esque tuning, but I ended up taking the Mirai in something of a different direction. The most significant distinctions compared to the U12t are the Mirai’s peak coming back up at 4kHz (versus 5kHz on the U12t) and significantly more energy at ~8kHz where the U12t dips. This basically gives the Mirai some more bite in the upper-midrange and more of a focus on sparkle in the treble. It also won’t sound as bass-y even if they graph similarly in the bass region. Basically, they sound like very different IEMs in practice, and I wouldn’t really think of the Mirai as being a U12t replacement.
Compared to the IER-M9, it’ll be a lot less warm and it’ll be leaner.
Doesn’t sound like the LCD3, sorry. Honestly, I found the LCD3/4 to not be my cup of tea, something like the UE Reference Remastered would probably be closer to that type of sound (but still not nearly the same).
