The Audio Store's Take on the 64 Audio Solo:
The 64 Audio Solo is a remarkable IEM featuring a 14.2mm planar magnetic driver, delivering an impressive blend of musicality and detail. With its elegant copper faceplate, lightweight build, and premium OCC copper cable, the Solo offers both style and comfort. Its W-shaped sound signature combines fast, clean bass, rich midrange vocals, and detailed, engaging treble. Whether you're a planar headphone enthusiast or an audiophile seeking lifelike sound, the 64 Audio Solo stands out for its balanced, natural tonality and immersive listening experience.
Introducing the 64 Audio Solo

The 64 Audio Solo is a revolution in portable high-end audio, offering full-range sound with a single planar magnetic driver. As the latest addition to the renowned tia™ line of UIEMs, Solo brings forward a rich heritage of innovation. By integrating groundbreaking technologies like Helmholtz resonators and electronic filters, it redefines sound tuning in single-driver IEMs. This remarkable design takes inspiration from past successes like the Fourté and Trio models while introducing new acoustic advancements to elevate the listening experience.
Planar Magnetic Driver: Precision and Detail
At the heart of the Solo is a 14.2mm planar magnetic driver, delivering remarkable transient response and high-frequency detail. Unlike traditional dynamic drivers, the planar driver’s diaphragm moves uniformly across the magnetic field, eliminating uneven movement and enhancing sonic precision. This ensures a full-range, high-resolution sound, usually requiring multiple drivers, from a single planar driver.
Helmholtz Resonators: Sculpting the Frequency Spectrum
The Solo introduces the world’s first Helmholtz resonators in an IEM, enhancing its acoustic performance. These resonators are 3D-printed into the sound chamber, precisely targeting problematic frequencies by resonating air at specific frequencies. This innovation provides a more controlled and refined high-frequency response, showcasing the true potential of planar technology.
LID®: Consistent Sound Across Devices
64 Audio's patented Linear Impedance Design (LID) compensates for electrical resistance variations that can occur when using different source devices. This ensures that the Solo’s sound signature remains consistent, whether connected to a smartphone, DAC/amp, or high-end digital audio player, preserving the intended sonic experience.
Apex® Core: Pressure Relief and Comfort
The Apex core technology integrated into Solo relieves pneumatic pressure, allowing for extended listening without discomfort. This design provides the listener with a natural, unoccluded feeling, enhancing spatial perception and delivering a highly immersive sound experience. The Solo’s ergonomic fit and balanced isolation make it perfect for long listening sessions.
Sound Signature: Dynamic and Immersive
The 64 Audio Solo delivers on the brand’s promise of musicality, balance, and detail. Its planar driver provides agile and precise sound reproduction, revealing subtle details within the mix while maintaining a cohesive soundstage. With acoustic notch filters and Apex core technology, the Solo’s high frequencies are expansive, while the bass offers substantial impact and deep sub-bass, creating a dynamic and textured sound experience.
Copper Eight-Braid Cable: Superior Connectivity
The Solo comes paired with an OCC Copper eight-braid cable, designed for low impedance and superior sound transmission. Available in both 3.5mm single-ended and 4.4mm balanced configurations, these cables ensure reliable connectivity while offering a durable, tactile feel.

I had ordered Tanchjim Bunny, amazing service and quick arrival of product before promised date. Totally recommend to everyone.
I really loved the design and detailed view of the iem earphone which I have received, I am so happy with the performance of the earphone, it was like listening to my same old songs like a new detailed enhanced version.. thanks for the product and quality

Good
This cable is great

Product with good budget. Great with my audioculer m61 mp3 player.

This is my first DAP and I have received it in good condition. So far, the music playback is perfect and I am loving it.

Got these after I ruined the cables for my Truthear Nova. Definitely better than the stock cable and the mic quality in my testing was pretty clear as well.
For the price, it's really a great product. The best part is that, many high end DACs do not allow the use of earphone/headphone's mic and inline remote but this one does. I am extremely happy with the product. Thanks a lot for such an awesome product. 👍👍👍👍👍👍👍👍

I absolutely fell in love with this IEM. This is an IEM that made me rethink what correct/natural should sound like. This one has a lot of bass which is good and bad depending on the tracks that you are listening to. The mid range is tonally correct. And the treble is very interesting. Interesting in the sense that there is not much lower treble or mid but there is noticeable amount air and upper treble presence which makes this non fatiguing and also helps percussion instruments cut through the bass. I really love the presentation. The only part where this IEM falls apart is in complex tracks. There it gets a bit jumbled up. And one thing is that you have to play them at higher than normal volumes to truly enjoy them and open up the vocals and treble otherwise they do sound muddy. They scale very very well with volume

It's a 6 star out of 5 star. Just don't look at anything else. Earaudio cables are best. It's neautral and clean and slightly warm because of copper.

It will be hard to believe although I hear a subtle noticable difference in the audio quality from the OEM cable.

It feels like i am hearing the songs for the first time. My first IEM and I am very happy with the sound. Perfect bass, not as much as you get in regular headphones which ruins the song.
Love the way you had packed my product. Also, the product was really good. Had a good audio quality compare to which you get in market nowadays. Happy to be your customer. Looking forward for more products. Thank you.
Good quality cable and sound quality.
The soundstage and imaging in games is awesome. I can hear every minute detail
