64 Audio - U18t

64's U18t or the 7th acoustics Asteria, those are the best with good gear, as they should be for their price points. Enjoy.

Ok so this if from my personal experience.... I have several iem range from sub 100 until 500 some I lent to my friends or I just keep on my house...I have several friends which audio hobbyist they have audio store so I have opportunity to try before I buy one..so someday I want buy 1000usd iem, read reddit and head-fi forum then go to my friend store...so I tried moondrop chu2 compare to my kadenz yes the quality is very different, compare again with letshuoer s15 the s15 better than my kadenz for my taste...so when I put monarch mk3 it's blow my ear, damn this iem so amazong and I decide to bought it....then several weeks later my friend call me then say I have 64audio tia demo and annihilator just come....with fully excited I'm going there when I tried both of them, I dont feel WOW like I tried monarch mk3 the first time then at that time I realize, mk3 is my peak and I cant tell the significant difference between mk3 - annihilator and tia So thats why I like to try and buy several 100-500usd iem and sometimes sub100 too because I can tell the difference and I can choose whats signature I want..like a week ago I choose simgot ea500lm rather than ew300 because I found the sound more aggresive because mostly my iem is warm and neutral.... So from my story, I have limitation and taste for me, spent 1000 iem in monarch mk3 is one of the best choise I ever made and beyond that price point my ears cant tell fhe difference so..but back again thats my experience and opinion....

I tried multiple 64 Audio IEMs at the February CanJam in NYC (my first) when I was looking for IEMs. I spoke with the 64 Audio guy at the table and talked a bit about the various models. He gave some impressions of the u4 (excellent) and u18 (great for an analytic presentation), but said the u12t was his personal preference. That recommendation came before I actually tried them, so it wasn't just reinforcing what I already said. After trying multiple 64A IEMs, I agreed that the u12t sounded the best. All of them sounded great, but the u12t was the winner. They fit reasonably well in my ear with the smallest tips in the little sample box the 64A guy gave me, which was a bonus as I have issues with IEM fit. Ultimately, and with the extra motivation of a discount at the show, I ordered the a12t customs. They were very picky about the molds, which I do appreciate. I had to have them done three times before they were satisfied with the pictures I sent. It was for the best. When they say "custom", they are not kidding. The fit is *perfect*. There are no tips to worry about. The seal is perfect, and the sound is fantastic. To compare and contrast your environment, my main headphones are the Focal Clear MG, and for room listening I use the Revel 126Be or 228Be. I've had maybe 20 hours with the IEMs so far, mostly with ambient, electronic, classical, and some jazz fusion. Everything I put through them sounds good, provided it's a reasonably well done master. EDIT: I should add that I tried a lot of IEMs at the show, not just the 64A stuff, across the spectrum of pricing.

I didn't try the Nio. I did try the u18, but to be honest I didn't hear that much of a difference. It may have been a bit more treble. I'm happy with my choice. I went in wanting the IEMs I liked the most, whether they were $50 or $3000. In the end, the u12t were what I liked and I'm happy with my choice. If I had bought the u12t at the show, I'm not so sure. I think I would try to sell the u12t if I were going to go custom. I don't really go in to collect audio gear. I want whatever I get to be what I reach for when I want to listen. In your case, I would consider picking up some different tips and try to get the best fit possible before buying a whole new IEM, unless you have a buyer ready to give you a reasonable price for the ones you have.

Still outstanding. In terms of isolation, they aren't noise cancelling obviously, but they do a great job of limiting outside noise. I haven't used them in any particularly loud environments, but I get a feeling of separation (from the surrounding environment) while still being able to hear something if I need to. While music is playing, though, the outside world may as well not exist. No issues with sweat. The fit and comfort is excellent, though after a while I do feel like I need to pull them out for a few. The fit is exact. I experience that with any IEM, however, and to be honest I like a bit of a rest no matter what I put on/in my ears. One weird thing is talking. I use them sometimes playing games when I don't want to put my full headphones on. If I'm in a game and, say, also in voice chat, the the seal amplifies my own voice substantially and it sounds kind of weird. Again, same with any IEM. Overall, still no regrets whatsoever, and I feel no motivation/interest at all in looking at other options. Definitely feels like a one and done for me.

I was at Axpona yesterday, listened to a lot of iem’s, and I was kind of amazed at how much everything mostly sounded the same. I tried every item from Thieaudio and while I had favorites, I would be completely happy with the hype 4, with the Divinity 14 and Origin being my favorite, but it was shockingly close. Same with 64 audio, liked all of their offerings favoring the u18t, followed buy the velour and u4s. At the Bloom audio table, they had almost everything to try. Crazy how much sounded the same. At the campfire table, I a/b’d the supermoon and astrolith, with the latter being better, but not $2k better. Diminishing returns really kick in super fast in this hobby.

Little late.. but 64 audio 18t in ears are the best thing I’ve ever found after 20+ pro years in audio.

That’s 64 audio’s whole thing. They built a port with filters into their iems. Essentially acts like having a molded earplug with set db filters (believe they have 12, 15, 20, and solid) that passes signal through it.
