Here’s my review for DynaQuattro
Pros: Deep, impactful sub-bass
Warm, natural tone and timbre
Perfectly balanced mid-range. Not too forward or recessed.
Excellent instrument separation and layering
Comfortable fit with good passive isolation
Cons: Treble lacks sparkle and air (not a major con for me)
Requires more power to drive optimally
Stock cable retains a lot of memory

Introduction:
Binary Acoustics is a relatively newcomer to the audio scene. Their previous release, Gizaudio X Chopin, had a mixed response from the community. Presenting the DynaQuattro—an IEM that is definitely highly anticipated and promising to put a new high bar on what a multi-driver dynamic IEM can deliver.
Design of the IEM and Cable:
The DynaQuattro comes with an elegant, modern look, showing off its metallic faceplate with recessed gear design in conjunction with a translucent resin body. This adds a lot of class to the IEM and gives it a kind of premium ruggedness. The IEMs come with a modular cable system, which allows for easy switching between 3.5 mm single-ended and 4.4 mmbalanced terminations. The cable is quite robust and manageable by itself but could be slightly softer to give more flexibility to the body and feel. The cable however retains a lot of memory making it impossible to keep in place, nice and tucked when folded.
It also comes with a pelican-type hard plastic case that ensures your IEMs will be very well protected while traveling.
Fit and Comfort:
It’s pretty amazing how the DynaQuattro has four dynamic drivers inside it, yet it is still comfortable in fit. The larger form factor may be a concern for few, but rest assured that the fit inside the ear is comfortable for long listening periods. The IEMs provide a great seal, offering extraordinary passive noise isolation, hence an increase in the listening experience while out and about as well.
Sound:
Sub Bass:
The DynaQuattro’s sub-bass performance is one of its stand-out features. Extension is really deep, giving a rumble that is as satisfying as it is impactful. This is very enjoyable with genres that center around sub-bass, such as EDM and hip-hop. The bass is so well-controlled that it doesn’t bleed into the mid-bass or muddy up the general sound signature.
Mid Bass:
The mid-bass in this piece is just punchy and dynamic, adding a good layer of warmth to the sound. It has enough presence to make bass-heavy tracks enjoyable without overpowering the mids. The well-defined bass notes provide a good texture and separation that keeps the sound clean and engaging.
Midrange:
The midrange of the DynaQuattro is slightly recessed however I felt that it was perfect. Not too forward or recessed. It does remain clear and detailed with a natural tonality that presents vocals and instruments sounding really lifelike. The transparency within the mids makes sure that both male and female vocals are portrayed accurately, although the upper mids will tend to be a bit forward for some listeners, and sometimes they can portray some female vocals as slightly aggressive.
Treble:
Treble on the DynaQuattro is smooth and non-fatiguing. It doesn’t have too much sparkle and air that some treble-heads may crave, but this makes it a great choice for those who are treble-sensitive. The treble extension is quite good here and is detailed enough to provide clarity without any hints of sibilance or harshness to bring out the nuances in the music.
Tone and Timbre:
The overall tone of the DynaQuattro is every so slightly warm and natural, typical for a properly tuned dynamic driver. The timbre is pretty realistic, making instruments sound legit. This makes DynaQuattro an IEM that’s well-made for any genre.
Staging, Instrument Separation and Layering:
It is moderately wide with good spacing and positioning. This will not be the widest soundstage for its price but it does offer a very nice holographic experience, especially for gaming and some of those nicely produced immersive tracks. Instrument separation and layering is good. Each element in the mix is clearly audible without it sounding cluttered.
Detail Retrieval:
The detail retrieval on the DynaQuattro is impressive, capturing micro-details that enhance the overall listening experience. It may not reach the extent of the resolution possessed by high-end multi-BA or planar IEMs, but still—this dynamic setup holds up very well, making it a really strong contender inside this price bracket.
Comparisons:
DynaQuattro vs Juzear 61T:
At the price point of the Juzear 61T, we find the treble to be tuned a little more balanced; it does represent a slightly more coherent treble extension with better details. Overall, the bass in DynaQuattro is greater in quantity and also tight and controlled, hence providing the sound with more punch and energy overall. If you’re looking for an IEM that sounds warm, natural, and also provides great weight at the low end, DynaQuattro is going to be for you. For those who are after a more neutral sound signature, with their treble having more finesse and sophistication to it, then the 61T may get the upper hand.
Please do note that I had a hard time listening to 61Tfor extended period of time due to the occlusion effect. The pressure inside the ears builds up fairly quickly and can become difficult to keep them on after 30mins or so. Wide bore tips were a better fit for 61T in my experience.
DynaQuattro vs Dunu x GizAudio DaVinci:
The DaVinci is, indeed, a really good IEM both in its technicalities and timbre. It has a more open and wider soundstage and more accurate mid range than the DynaQuattro and better imaging. On the contrary, the DynaQuattro has more body and more engaging bass punches and the treble has better extension compared to the DaVinci. So, for the more bassy genres, the DaVinci will do better. I felt the bass quantity on the DaVinci was a little too much for my liking but DynaQuattro was just perfect.
The choice between the two will vastly depend on what kind of sound signature you prefer and what genre of music you would like to listen to with the headphone.
Conclusion:
The Binary Acoustics DynaQuattro in the IEM world offers such a strong setup, considering its unique, four-dynamic-driver setup, which delivers a warm, natural sound coupled with great bass performance. It aligns really well with my preferences as it does put together quite a compelling package of sound quality, build, and comfort.

Do you consider this as a hard to drive? I’m assuming so due to the driver configuration
Umm, I wouldn’t call it hard to drive as such but it does benefit from more power.
DynaQuattro vs Juzear 61T:
At the price point of the Juzear 61T, the treble is tuned more balanced and has a slightly more coherent treble extension with better details. In comparison, the DynaQuattro’s bass is greater in quantity and also tight and controlled, providing the sound with more punch and energy overall. If you’re looking for an IEM that sounds warm, natural, and offers great weight at the low end, the DynaQuattro is for you. For those seeking a more neutral sound signature, with their treble having more finesse and sophistication, the 61T might have the upper hand.
Bass: The DynaQuattro excels in the bass department, with its quantity and tight control delivering more punch and energy. It offers a deep, impactful bass with excellent slam and texture. This makes it highly enjoyable for genres that benefit from a strong low end. The 61T, on the other hand, provides a more balanced bass response. While it doesn’t deliver the same visceral impact as the DynaQuattro, it integrates well with the rest of the frequency range, maintaining a more neutral presentation.
Mid-Range: In the mid-range, the DynaQuattro has a more not too recessed and not too forward presentation and its detailed. Vocals and instruments are more prominent and clear, making it ideal for listeners who enjoy a mid-range-centric sound. The 61Tpresents a slightly warmer mid-range, with male vocals and instruments sounding fuller and richer. This warmth adds a pleasant tonality but might not have the same level of clarity and separation as the DynaQuattro.
Treble: The treble on the 61T is refined and sophisticated, with good extension and detail retrieval. It provides a smooth, coherent treble experience that enhances the overall neutrality of the IEM. The DynaQuattro’s treble, while also detailed and clear, lacks a bit of the airiness that the 61T provides. However, it still offers a high level of clarity and avoids sibilance, making it very pleasant for extended listening sessions.
Detail Retrieval: Both IEMs excel in detail retrieval, but they do so in different ways. The DynaQuattro’s almost perfect mid-range and impactful bass bring out micro-details in vocals and instruments that might be more subtle on the 61T. The 61T, with its balanced tuning and refined treble, captures the nuances in the upper frequencies better, making it excellent for intricate, high-frequency details.
Soundstage and Imaging: In terms of soundstage, the DynaQuattro offers a more immersive experience with a larger, more enveloping stage. Its imaging is precise, allowing for clear placement of instruments and vocals within the soundscape. The 61T has a more intimate soundstage, providing a closer, more personal listening experience. Its imaging is also accurate but might not feel as expansive as the DynaQuattro.
