A Journey with Binary Dynaquattro 4 Dynamic Driver IEMs

In the world of audio technology, there are few experiences as immersive as listening to your favorite music through a set of high-quality in-ear monitors. Binary Acoustics has taken this experience to the next level with the Dynaquattro, a marvel of engineering and design that promises not just to play your music, but to transform it.

The Binary Dynaquattro achieves this with a combination of three specialized dynamic drivers and a passive diaphragm, delivering a total diaphragm area of 193 square millimeters. This setup ensures a wide and detailed frequency response, from the deepest bass to the most delicate highs.

The Dynaquattro’s unique three-way frequency crossover and independently structured acoustic tubes allow each driver to perform at its best, offering a sound that is both powerful and precise. Whether you are diving into the low frequencies with the 10mm dynamic driver or exploring the high-frequency details with the 6.8mm aluminum diaphragm, the clarity and depth are excellent.

Beyond its acoustic capabilities, the Dynaquattro boasts a design as sophisticated as its sound. With CNC-machined aluminum alloy face panels inspired by steampunk inspired gears and machinery, it symbolizes the precision and innovation that Binary Acoustics is known for. The high-purity OFC silver-plated cable ensures that this exceptional sound quality is maintained, while the interchangeable plugs add a touch of versatility.

Opening the box of the Binary Dynaquattro is a straightforward yet exciting experience. The black box features a sleek black sleeve adorned with steampunk-inspired mechanical gears in a matte gold color. Inside, you'll find the IEMs nestled securely alongside a box of silicone tips. Underneath the foam padding, there's a rugged carry case containing the cables and plugs, ready for you to explore.

Tonality and Tuning

The Dynaquattro presents a warm tonality characterized by a balanced sound with a sub-bass lift. It offers just enough rumble without being boomy and a vivid upper treble. This results in a sound profile that is warm and balanced, with a particular emphasis on upper mids. The IEM may come across as slightly U-shaped, with beautifully textured bass and mids complemented by balanced treble, adding a sense of airiness and dimension to the soundstage.

Driver Implementation

At the core of the Dynaquattro’s performance is its three dynamic drivers and one passive diaphragm driver configuration. The meticulously tuned drivers cover the full frequency range: a 10mm dynamic driver handles the low frequencies, while 8mm and 6.8mm drivers manage the mid-treble frequencies. The custom 6mm wool paper passive diaphragm adds reverberation to the low frequencies, and the custom three-way crossover ensures a cohesive sound. The result is smooth, crisp sound with exceptional balance and brilliance in the treble, alongside clear and natural vocal and instrument reproduction.

Bass Performance

The Dynaquattro’s bass profile is warm and balanced, with sub-bass and mid-bass at the same level. This results in well-controlled and precise bass that isn't overly tight but still fun. The sub-bass is slightly more pronounced than the mid-bass, maintaining excellent separation and layering. The bass response is fast, with good decay and reverberation, delivering satisfying slams and rumble when needed. While it may not satisfy die-hard bass heads, its controlled and detailed presentation will appeal to those who appreciate a fun, detailed low-end that transitions smoothly to the lower mids without sounding muddy.

Midrange Warmth

The Dynaquattro shines in the midrange with its warm yet energetic presentation. The transition from bass to lower mids is clean and flawless, ensuring clarity in male vocals and instruments. Female vocals and upper mids offer brightness and detail, making them non-fatiguing for long listening sessions. The midrange maintains a good balance of intimacy and energy, particularly enjoyable for vocal-centric music or string instruments. Compared to the ARTTI R1, the Dynaquattro's vocals are slightly recessed, adding depth to the soundstage.

Treble Excellence

The treble of the Dynaquattro is surprisingly bright for a quad DD set and well-executed, providing a refined and extended response that enhances the overall sound. The treble is detailed and crisp, allowing intricate details to be easily discerned without overwhelming the listener. The treble extension adds a significant sense of space and airiness to the soundstage, enhancing the immersive experience.

Detail Retrieval and Soundstage

The Dynaquattro excels in detail retrieval, delivering a high level of resolution across the frequency spectrum. The well-implemented three-way crossover effectively divides the frequencies, resulting in clear transients and textured bass notes. The soundstage, while not exceptionally wide horizontally, offers good depth and precise imaging with a holographic feel. This makes the Dynaquattro excellent for various genres, especially electronic, jazz, and vocal-centric music, where its sonic prowess shines.

Timbre and Technicalities

The Dynaquattro boasts a natural, neutral-warm timbre, fast transients for a DD set, and good dynamics. Its soundstage is above average, with good depth and height and slightly recessed midrange presentation. The stereo imaging is close yet wide, offering a well-layered and immersive listening experience. Instrument and vocal separation is handled adeptly, maintaining clarity even in congested tracks. The IEM excels in creating compartmentalized regions within the sound field, thanks to its well-implemented three-way crossover.

Conclusion

The Binary Dynaquattro is an exceptionally crafted IEM that delivers a warm, balanced, and energetic sound profile with crisp resolution and good detail retrieval. It is particularly suited for listeners who value musicality, with a well-textured, layered, and punchy bass response. While it may not cater to those seeking a brighter, more analytical sound, its precise and immersive audio experience makes it a standout choice for those who love getting lost in their music. The Dynaquattro’s excellent instrument separation and layering, thanks to its exceptional three-way crossover, make it a joy to listen to and a worthy addition to any collection.
