So, they’re finally here…the long-awaited 64 Audio Solos. I have to be honest, I’ve missed not just the idea of owning 64 Audio equipment, but also the connection I feel with the brand. Following a company that shares my core beliefs as a Christian is really important to me. I dislike the idea of supporting brands that intentionally associate their products with false gods, as so many do these days. It’s a trend that seems to never end, and even the companies that don’t start out doing it, eventually do.
Take Empire Ears, for example, with their long history of Norse and pagan god references. Kinera is another company that goes out of its way to make sure you understand the spiritual undertones of their products, with explanations right on the box about the names and beliefs behind them. So, it’s a breath of fresh air to see that 64 Audio’s history and foundation are grounded in Christ.
Trust me, getting these IEMs isn’t just great for the sound, it’s about supporting a company that’s trying to do the right thing in a world that often rejects the very ideas at the core of their mission.

Now that that’s out of the way, let’s talk about my thoughts. The unboxing experience was a pure delight. I love the attention to detail that went into this product. Everything, from the wiring and stitching to the color, and even the lightweight feel adds to the overall quality and joy of using it.
The look of the IEM is unlike anything else on the market, whether from 64 Audio or any other manufacturer. I love the gold and brown tint on the black case, especially with the 64 Audio grills on the IEMs. They fit so well and are so light that it almost feels like I’m wearing wireless earphones because I can’t feel the cable at all. This is a huge plus, as with every IEM I’ve used, I’ve always felt the cable weight pulling down around my ears, even if just a little. This helps elevate the immersion levels of the IEM.
Speaking of immersion… this unit is masterful at it. The engagement you feel with the music is almost magical. It’s like the technical superiority of the IE600 had a baby with the lush, smooth midrange of the ThieAudio Monarch Mk2. Vocals are rich and smooth, nothing is fatiguing or out of place, while still being able to handle bass and sub-bass that hits you emotionally


All of this truly comes down to the engineering of the IEM. The Helmholtz Resonator and planar driver play a significant role in this. The sound is incredible, hands down. I’ve been wanting a proper planar driver for IEMs, and now I finally have it.
64 Audio’s ability to present details and resolve issues that cause distortion while delivering proper perfect balancing of the drivers on the left and right by properly matching the driver units is remarkable. It shows their dedication to tolerances—something most other brands allow to slip. This unit performs as if the right and left drivers are perfectly matched to the point where they feel identical. You might think this is standard for all companies, but it’s not. In fact, 64 Audio is the only company I’ve seen put in the effort to match the drivers on both sides to such an exacting degree, it’s honestly impressive.
Most people have no idea how difficult it is to create driver units for the right and left sides and ensure they don’t have slight differences. I have tons of IEMs that fail in this area. Things like my Dunu Sa6 MK2 do not measure for this issues and you can tell by it’s centering. 64 Audio takes the time to match them carefully, while other companies just take one right driver and one left driver, put them in the shell, and don’t test for variances before hand. 64 Audio also makes sure the proper amount of venting is present in their IEMs unlike some other IEM that claim to have venting but either have poor venting systems or not enough.

This is why the sound from this IEM is so extraordinary, it’s the best complete package I’ve had to date. The way the sound is presented makes it feel like you’re in a perfectly treated sound room, one that allows for ideal clarity, reflected sound, and resonant tones that bounce all around you. I initially thought this might be a classical-focused IEM, emphasizing detail while lacking warmth or bass that I was used to, and boy was I wrong.
When I got these and listened to all my favorite genres; bass-heavy songs, metal, house, and classical—it didn’t matter. It’s like a switch was flipped, and the IEM just knows how to present each song in the perfect way, even surpassing all other IEMs in bass, or treble, or in mids. The 64 Audio team absolutely nailed this IEM creation, especially if you get the right seal and a proper fit. With the right tips, they hit like a freight train—but only when it’s called for.

I’m still in disbelief that they outperformed many of iEM in bass. When I first got these, I thought that would be the one area I might have to compromise on compared to my Monarch Mk2, but it wasn’t. It beats the Monarch Mk2 in treble and bass, all while maintaining vocal presence and intimacy. I can’t come up with a single thing that this IEM doesn’t do great in and that’s scary being that there is no other universal IEM on the market, in my opinion that looks better than this that isn’t a custom.

Can you find other IEM’s that might have a little more bass, or a little more treble if you truly need more? Sure. The Valhalla is probably the best I’ve heard on bass and technical details but its big and the name is just not what I’m comfortable with personally. Just know that the law of diminishing returns is active and alive in this space. And even when you find it …they won’t align with the quality on this. With that said, this is possible the biggest argument for Cost matching IEM differences that I’ve come across. This unit is $1400 and I got it for $900 in like new condition with every single thing in the box and no signs of wear. I was blessed to get this at this price and to be able to afford to do it. However, this unit is very easily worth the $1400 for the MSRP that is labeled for it. In fact I would say it very well could be worth more than the $1400. Final review, nickname, and score coming soon!
