Oh cool. No otoscan anywhere near me in Australia!

I recently want more mid-bass and lower-midrange body to U12T. Any good EQ profile for this? New to PMEQ.
Since I’ve been traveling a lot this year I wanted to buy a TOTL IEM to make the trips a bit more tolerable. I purchased a pair of Andromeda 2020s this Spring and have been thoroughly enjoying them while in airplanes and Ubers. The downside is that sadly, for me, the “pointy” case digs into my ear so I can only tolerate them for 2-3 hours max before I need a break. So then started my quest to trial some other similar-sounding IEMs and see if a replacement was feasible - lest I ended up filing down the Andro’s case and giving up on resale value. My first subject - a pair of U12Ts - arrived today. I can definitely say they’ve lived up to their reputation!
I’ve only had about 30 minutes to listen to them so far, but I wanted to pass along my initial thoughts. (BTW I was using an AQ Cobalt with high quality Spotify tracks through my iPhone 12. This is my typical travel setup)
Relative to the Andro 2020’s, my initial impressions are (in order of appearance):
- They’re bigger (thicker?) than the Andros - but feel very comfortable in place. I used the dark gray memory foam tips and they seemed to work very well.
- Sub-bass! I’ve never heard these frequences from an IEM before. Amazing!
- Bass! Maybe it’s due to the sub-base extension, but all bass frequencies seem to have more punch and depth than the Andros
- Soundstage seems on par or maybe slightly smaller (?) than the Andros, but I need to find some better tracks to use for testing this aspect
- Slightly lower midrange response relative to the Andros. Not necessarily a bad thing, but more listening time will help me better gauge this aspect.
- Mid- and high treble was very crisp and detailed - not quite to a fault but it’s almost like turning up the “sharpening” filter on an image in Photoshop. Again, need to listen to more tracks to see if this becomes bothersome… my initial guess is that I’ll get used to it.
More to come on this, but so far I’m quite pleased with these IEMs. If they end up on the top of the heap I may even sell them and get the CIEM versions.

Thank you very much for the review Andrew! As you recommended on my U6T vs U12T question, I’ll go for the U12T, now I should ask you… Any little nice, portable DAC / Amp that I could bring with me (airplane, etc) that would be enough for the U12T as well as a Focal Stellia?

LATE TO THE PARTY
I have spent an inordinate amount of time trying to find the perfect IEM “for me”. This includes three custom IEMS, dozens of universal IEMs, and practically every eartip in the market.
When I say “for me”, it means that I have to take into account my hearing acuity; the size and shape of my concha; and the diameter, narrowness and depth of my ear canals.
One reviewer noticed an annoying peak at 16k, oblivious to me as my hearing tapers off well below that frequency.
What I find most appealing are the comfort of the shell, the balanced and musical presentation at all the frequencies that I can hear, and the accurate sound stage presentation. Finally, 64 Audio have gotten timbre right: the presentation of each musical instrument sounds incredibly close to what that instrument sound like live.
I have spent a lot of time listening to live music, and my quest as an audiophile is to get as close to that experience with my equipment as possible. 64 Audio U12t is as close as I have found in an IEM to that live experience.
One of the thrills of this avocation for me is to discover a playback technology that uncovers nuance and reality in my music library. Listening with my U12t delivers that thrill.
Let the listening begin!

I’ve been a long time fan of my A6 customs. I’m trying to decide if it’s worth it to upgrade to UT12. I love everything about my A6s except for when the base gets real deep on EDM tracks. The deepest base kind of rolls off and doesn’t have enough oomph. I’m really enjoy the details and technically of the A6 sound. Will I see a big jump up in the details and base with the U12T? Or would I see any small differences and getting to the point of diminishing returns? Any advice is appreciated

This is such a matter of personal preference, that the only advice I can give is to try them in your own ears driven by your own gear. Only then can you be sure.
As far as the respected reviewers go, the U12t get top ratings from all as an “all-rounder” meaning they do everything pretty well.
