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!
Ah 1100$ perfect, right in my budget.
/s
I remember you said in the past you don’t like appearing on video but these days you’ve become one of the Headphone show’s best presenters. Do you enjoy it more now that you are better at it?
What are your thoughts on the rise of planar-magnetic technology in the IEM world? Any other new trends you’re hoping to see in the future of IEM’s?
Will the Mirai have ear pressure venting like 64 Audio IEMs or the NO Butastur? If not, why?
Can you share something on the development of its design and form factor? It seems like it’s bigger than the previous releases of Dunu.
What was the consideration for using a BA supertweeter over an EST for the Mirai?
Will you include your signed workout pics in the box?
Also why Dunu?
What’s your favorite over ear headphone?
None of them 🙈
But if I HAD to choose one, it’d probably be the Susvara or the HE1
What is your favourite driver set up in IEMs?
Single Dynamic drivers, Full BAs, Planar or Hybrid etc.
Were you able to use your favourite driver type in Mirai?
Can you share your impression of Mirai compared to U12T and Sony Ier m9 ?
Does it sound lean thin and bright or thicker and natural in general?
how is the bass and vocals does is it sound like Audeze lcd 3? I’m still dreaming of iem that sound like lcd 3.
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).
I would like to pick your brain from an IEM knowledge perspective if that is okay. In my journey I went up to the $1k range and back down to settle into the Moondrop Kato. It took that journey for me to realize that I needed the longer nozzles on the Kato to get the fitament correct. Turns out for me to get the same sound that the reviewers talk about, Its just what my ears need. I did try Eytomotic but it was too far and unsettling. Do you know of any other IEM that have a similar fit/long nozzle like the Kato that are not so far as to by Eytomotic?
who’s your waifu, and why is she a 300 years old tan loli demon?
Are there any genres of music the Mirai plays particularly well? Or, could you share any tracks you used for reference while tuning the Mirai?
Have you ever heard a BA driver hit like a dynamic driver in the bass, or are all BA IEMs doom to have worst dynamics in bass than the dynamic driver counter part?
Any plans of purchasing a 5128 in the future?
