I come with my new discovery, the
634EARS 9iNE! It is the evolution of 8iTE, the previous flagship of them before the LOAK came into existence. More details of the product can be found here -

I have a special connection to this IEM - I was fortunate to be one of the beta testers of the prototype. Musashi San told me that he was thinking of targetting the western audience more with 9iNE, and was tuning it in such a way. However, even while doing that, he made two different tunings - one which was more spacious, but thinner sounding with more details and crispness, and the other one a bit more organic and thicker. I was sent the first one. While I could understand why it might have an appeal, it definitely was not suitable to my taste - and I told him the same. I described in detail what I felt was not right, what I liked, and what I would like to see improved, and then sent it back. Point to note - all the logistics and involved taxes was taken care of by him.
After that, he released the 9iNE with the final tuning, and told me it was different than the one I listened to. The final version is bit more organic and thicker. Oh right, he did not release only one version - rather he released 4 versions, 9iNE (with wood backplate), 9iNE-B (Brass backplate), 9iNE-C (Copper Backplate), and 9iNE-S (SS Backplate). The S version is closer to the tuning I heard to, albeit slightly improved. I was interested to get one for daily beater iem, and he suggested me the 9iNE with Rosewood backplate. I went with his suggestion as he definitely knows better. Oh, the body is made of a single piece of blackened stainless steel.
(PS: The MIROAK-S that I have has a single piece Aluminum body with an SS backplate, and LOAK-T(CL) has a Titanium front chamber, SS back chamber, and Cocobolo wood backplate. The nature of backplate does affect the sound signature - Musashi San sent me a MIROAK with a wooden backplate along with the 9iNE prototype to check against the MIROAK-S, and I could certainly feel the slightly softened note edges on the sample MIROAK.)
Welp, now that I have the 9iNE in my hand...I can only say that I am quite pleased by it. 634EARS have a house sound, and that is very much balanced - such that it will most certainly will not make you go WOW at the first listen, but you'd be hard-pressed to find anything that is dissatisfactory, and eventually you will find out how refined and matured the sound is, the point at which you will fall in love. Well, I did.
The sound profile is focused on getting a balance of all three frequencies while keeping the sound as dynamic as possible. The bass has quite a nice full punch, goes deep. Lower midrange has a nice full body that is not too thick, upper midrange has a sudden burst of energy that makes the female vocals sound alive - it slightly touches the hem of sibilant region, but never actually gets into it. Treble is slightly toned down compared to the midrange, but still has a nice amount of energy - lower treble has slightly more energy than the upper treble. The sound signature overall is quite airy, with a very nice imaging and separation, and a very well-rounded soundstage with decent extension in all three directions.
Sounds pretty generic, right? That is how the 9iNE is - balanced, but most certainly not boring. For 37800 JPY, or around $290, I would say it is a pretty competitive set.
In the photo below is the 9iNE Rosewood, paired with Satin Audio Gaia II cable (I had to change the cable as 634EARS only supply single end cable...they also had the option of 4.4 mm plug, but I wanted to use it with my Qudelix 5K as an on-the-go solution, and I simply cannot settle for single end when balance option is there, hence an immediate cable swap.) The iem comes with a huge jute bag that seems quite handy. The tips are not the stock tips.
