About 64 Audio

64 Audio is a US based company that specializes in making custom and universal in ear monitors, but has recently dipped their toes into making studio/live belt packs. As you can find out in the interview we did with them a few months back, 64 Audio started out as 1964 Ears and has renamed themselves a little over two years ago. Their core of employees is the Belonozhko brothers who all manage different departments. They have been around for a little over seven years already, and have started out because of a project their CEO, Vitaliy, has been working on – an in-ear monitor for his wife. This project later on became what we know today as 64 Audio.

They are also one of the few companies that develop new technologies in order to give their customers the best and safest listening experience. They have introduced TIA (Tubeless In-ear Audio) and APEX (Air-Pressure EXchange), both of which can be found in their custom in ear flagship, the A18t. You can consider TIA as some sort of hat-less balanced armature driver that fulfills its job in a special sound-chamber and doesn’t put out sound via a regular tube and dampener system. This way the treble frequency response is more extended and the resonances of the tubes are eliminated, giving a more enjoyable listening experience.

APEX is an interchangeable system that drastically reduces the pneumatic pressure on the eardrum, which can be found on regular custom IEM designs, and therefore enhances the safety of your hearing.

64 Audio also is one of the very few companies that 3D prints your custom IEMs. It works like this: you take your regular impressions at your trusted audiologist, send them to 64 Audio, they scan them with their hardware, edit the scan to make it printable as a custom in ear and then 3D print them. The entire process took close to three weeks for them to finalize my A18t.

64 Audio also closely works with many professional musicians, artist such as Alessia Cara, Seal, Bon Jovi or Beyoncé are known as their clientele. This definitely says a lot about their reputation.

About A18t

The A18t (or A18 Tzar) is considered 64 Audio’s flagship of custom in ear monitors, there only is one other model ranked higher, the Tia Fourté. Which only comes in a universal form factor though. Both models can be considered as co-flagships. We’ve seen quite a number of companies doing the same recently, positioning not only one but two different models at their top of the line. I think it is a nice thing to offer your customers two outstanding choices.

The A18t, as its name already spoils, is constructed with non-less than 18 balanced armature drivers per side. Eight bass drivers, eight mid drivers, one high-mid driver and a single TIA high driver can be found in its impressive driver count. Especially the TIA high driver does an outstanding job, but more on that a little later.

The A18t also comes in an universal reincarnation in form of the U18t, but since I’m a big sucker for customs, I am happy to review the custom-built version of it.

A daytime code monkey with a passion for audio and his kids, Linus tends to look at gear with a technical approach, trying to understand why certain things sound the way they do. When there is no music around, Linus goes the extra mile and annoys the hell out of his colleagues with low level beatboxing.

    Hi Linus,

    Did you managed to compare for JH Layla and also use WM1Z DAP?
    I am curious to read for your findings. 🙂

      Hi Thurein,
      I don’t have a Layla yet to compare, sorry. I also don’t have the WM 1Z. Would love to compare, but for now it’s impossible for me…
