Today we take a close look at the all-new 64 Audio A18s – their latest flagship CIEM retailing for $2,999 USD.
Disclaimer: 64 Audio provided the A18s at no cost, I only had to pay to import them. 64 Audio is not a site advertiser or affiliated with Headfonia. The A18s remains 64 Audio’s property and can be asked back at any time. Many thanks for the generosity and opportunity!
About 64 Audio:
64 Audio is an American brand of universal and custom fit In Ear Monitors seated in Vancouver, Washington. They have been previously known as 1964 Ears before they rebranded themselves to 64 Audio. The company was started by Vitaliy Belonozkho, who is also their chief sound engineer.
Back in 2010 the company was started after Vitaliy was building a monitor for his wife. Now, nine years later, they are one of the driving forces in the field. 64 Audio is one of the brands that continuously pushes the envelope for technologies. They have brought many inventions to the market. With their tia drivers they have introduced a completely new balanced armature driver, of which you can think as a hat-less design where the membranes radiate freely.
64 has also introduced apex modules, which stands for Air Pressure Exchange, these help your eardrums handle the pressure built up by conventional, fully closed CIEMs. Think of it as a secondary eardrum, placed in the audio path before it reaches your human eardrum. Apex relieves pressure and thus makes it easier for your ears to handle the audio waves.
Aside from these two inventions, 64 Audio has also released LID – Linear Impedance Design. This flattens the impedance curve of the monitor, making it more resistant to varying output impedances of many sources. Since 64 Audio is a pro-focussed brand, it only makes sense that they release a monitor that works well with high impedance pro-gear as well as low impedance audiophile electronics.
Many professional musicians use 64 Audio custom IEMs on stage. You can find performers like Beyonce, John Mayer, Bon Jovi and many others on their artist roster.
We checked out quite a few of their products here on Headfonia in the past. If you want to check them out, you can do that right here:
The A18s is 64 Audio’s latest introduction. It is their co-flagship CIEM next to the A18t, which has served as reigning king over the lineup since late 2016. Throughout all the years, the A18t has been recognized as one of the absolute best monitors available. And after four years, 64 Audio decided to not introduce a successor, but a second flavor to it. The A18s is exactly that. It builds upon the A18t, but is meant to have a warmer and fuller sound.
Since 64 Audio’s main clientele is the professional musician, it only makes sense, that they introduced the A18s as a monitor aiming at them. With LID they included a vital technology for them in the A18s. It ensures the user that their CIEM will always be faithful to the original frequency response, even when the output impedance of the source is going crazy high.
The A18s comes with a total of 18 balanced armature drivers per side. Eight low-end drivers are accompanied by eight mid-range drivers, a single high-mid driver and a single tia high driver. The tia driver sits right at the end of the nozzle, which you can peek at if your shells are clear or translucent.
Of course the A18s will also come with 64 Audio’s apex technology. As with all their custom IEMs the apex modules can be swapped out. Every set of A18s’s will come with both modules, so you can go from m20 to m15 in just a couple of seconds. The m20 is installed as standard module, while the m15 is sitting in the supplied carrying case.
The A18s has a nominal impedance of just eight ohms, while its sensitivity is rated at 106dB/mW. The drivers are assigned frequencies by a four-way passive crossover. Due to the virus outbreak and state wide lock-down, the build time for one set is currently eight to nine weeks. You can shorten the time down to six business days when you pick the rush-order option. This comes at an up-charge of 249 USD though.
The A18s can be bought either directly from 64 Audio, or one of their global retailers for $2,999 USD. Every custom IEM from 64 Audio comes with a two year limited warranty.
