From the moment I first held the 64 Audio Duo in my hands, I was intrigued to see how this special IEM would transform my musical experience. The Duo’s dual-driver structure and 64 Audio’s innovative approach to audio engineering make me start this review with particular excitement. I’ve always felt deeply connected to music, and I couldn’t wait to see how Duo would add to that connection. I was wondering how Duo would accompany me on my journey to discover the details, depths, and textures of music.
64 Audio Duo is equipped with a variety of unique technologies that make the Duo unique and provide it with outstanding sound quality.
1. Tia: Tia (Tubeless In-ear Audio) technology is a special innovation of 64 Audio and plays an important role in Duo. This technology is based on a tubeless high-frequency driver, which allows sound to be transmitted more naturally and clearly. Tia involves removing tubes and traditional audio filters within the headphone, allowing the sound to follow a more direct path with less distortion.
2. ApeX: 64 Audio’s ApeX technology is used to manage sound pressure and improve the listening experience. This technology reduces pressure inside the ear, increasing comfort during long listening sessions and minimizing potential hearing damage. It also helps to perceive the sound in a more balanced and natural way.
3. LID: LID (Linear Impedance Design) technology allows Duo to deliver consistent audio performance with different devices. This prevents audio coloration when the Duo is used with a variety of sources and amplifiers, allowing the headphone to perform equally across a wide range of audio channels.
4. Wave Synch: The 64 Audio Duo model is designed to perfectly synchronize the sound waves of different driver types (such as dynamic and armature) in terms of timing and phase. This innovative technology reduces phase differences and timing errors between drivers, offering a more natural and cohesive sound experience. By using advanced signal processing and acoustic design principles, it reduces distortions and colorations at the point where sounds from different driver types meet. This gives multi-driver systems a balanced, accurate, and unified sound. Wave Synch technology showcases 64 Audio’s innovative approach to sound engineering and their commitment to enabling users to experience their music in the highest quality, ensuring the Duo delivers a detailed and natural music experience across the entire frequency spectrum.
The combination of these technologies allows the 64 Audio Duo to deliver a detailed and wide stage, provide a natural and balanced sound profile, and deliver a consistent listening experience even when used with different devices. Thanks to these innovative features, Duo has become an attractive option for professional musicians and audio enthusiasts.
Box, 64 Audio Duo and Cable
When I received the 64 Audio Duo, I was very impressed with the presentation of the box and its contents. The box had a stylish and minimalist design that reflected the quality and premium feel of the Duo. When I opened the box, I found, in addition to the Duo headphones, various accessories that would complement the user experience.

This bag stands out for being both durable and portable, so I could safely carry the Duo with me.

This ensured that the headphones fit my ears perfectly and that the isolation was optimized.

The cable had a balanced structure in terms of durability and flexibility and was also produced with a quality that could transmit the audio signal to the headphones losslessly. The cable also impressed me, as it produced minimal microphonic noise during use and was comfortable for daily use.
The semi-open structure of the 64 Audio Duo had a tangible impact on my usage experience. This design choice allowed the sound to spread more naturally and on a larger stage, creating the feeling of being in a concert hall while listening to music. The semi-open structure allowed some sound to leak out and external noises to be let in to some degree, making me feel connected to my surroundings rather than a completely isolated shell.

64 Audio Duo is a unique entertainment headphone with its open stage, almost physical bass, and sub bass that shakes from the first moment. It’s perfect for being in the electronic music clubs rocked by The Glitch Mob band. Timbre is neutral to warm. The songs that sounded cold in the original do not sound so cold to me with Duo. All his hot disposition adds fun, yes, but it takes away from the technique. fair trade
Dynamism is very good. The transformation from the quiet background and calm voice in Innuendo to flamenco and the details I heard afterwards make me smile with pleasure. Rhythmic hand claps and volumes of guitar strings are in the ear. Instrument separation is extremely good. Even in 70s funk rock, everything on stage is clearly separated. Especially in crowded tracks, it does not provide a soup of micro-details like an analytical headset. Just right for listening comfort. Besides, I did not encounter any sibilance in the vocals.
Bass
Despite all the bass power, it delivers what’s on the record. And it doesn’t drown out other instruments. As a general characteristic, there are slightly harsh bass hits. My experience with the 64 Audio Duo has been quite impressive, especially regarding bass frequencies. These headphones enriched my music listening experience by delivering strong and detailed bass sounds. The Duo’s bass is deep and impressive, spanning a wide frequency range. In this way, the bass sounds stood out clearly and undistorted in the music I listened to. The design of the headphone felt like it was optimized to emphasize bass sounds. As someone who is particularly interested in music production, DJ performances or bass-heavy music genres, I greatly appreciated these features of Duo. These headphones seem to be an ideal option for users who focus on bass sounds and are looking for a quality sound experience.
Midrange
The fluidity in the string arrangements is astonishing. In addition, it allows me to choose different strings within the songs. What’s even more fantastic is that it maintains this fluidity and clarity at the same time as the drum explodes. Fine details like these prove that it still deserves its price. While using the 64 Audio Duo, I was particularly impressed by its midrange performance. This headphone offers a very balanced and clear sound in the mid-frequency range. Vocals and instrumental details stand out clearly and vividly in the Duo’s midrange. Midrange sounds were neither too dominant nor overshadowed; It brought out the natural tones and subtleties of the music by providing complete balance. This became especially apparent when listening to vocal-heavy tracks and complex instrumentation. The Duo’s midrange performance enriched my overall listening experience and helped me feel the music in a fuller, more vibrant way. This feature was very important to me as someone who listens to all kinds of music and cares about the naturalness of the sound.
Treble
When using the 64 Audio Duo headphones, the treble performance was generally satisfactory. The highs are presented with clarity and detail, but they stay clear of being overly harsh or distracting. The sounds of high-note instruments are expressed clearly and accurately in the Duo’s treble range, which positively affects my listening experience. The natural and balanced presentation of treble improves the overall sound quality. As someone who cares about the details of treble sounds, I appreciated this aspect of the Duo, but I might not describe it as an experience that fully exceeded my expectations. Overall, though, the Duo’s treble performance kept my music listening experience at a satisfactory level.
Comparison_
Vs Softears Twilight: For me, comparing the differences between 64 Audio Duo and Softears Twilight is quite an interesting experience. With its two-driver structure, 64 Audio Duo makes me feel like the music is opening up as a three-dimensional space around me, with its richness of detail and wide stage presentation. The bass is precise and well-controlled, offering a solid foundation without overwhelming the mix. On the other hand, with its single dynamic driver, Softears Twilight offers a warmth and interaction that is felt, especially in the midrange. Clarity in the midrange is outstanding, bringing vocals and acoustic instruments to life with natural and authentic timbre.
The Duo’s treble adds more air and a sense of detailed, openness; Twilight’s softer treble profile provides a more forgiving experience, especially during long-term listening. While both IEMs are superior in terms of build quality and comfort, Twilight stands out for its comfortable fit and is ideal for long-term use. Although Duo’s unique design provides comfort, it may require some getting used to for some users. In conclusion, the choice between them depends on personal sound preferences and comfort, with Duo standing out with its detailed stage presentation and Twilight with its warm and expressive midrange.
