The Binary Dynaquattro 4DD IEM has an impressive array of four drivers: 10mm, 8mm, 6.8mm dynamic drivers, and a 6mm passive diaphragm. These combine to create a substantial 193 square millimetres of total diaphragm area. Including a three-way frequency crossover enhances the pair's capability to deliver a wide frequency response range with minimal distortion and high-resolution clarity, promising an immersive audio experience.
Excellently Detailed Wide Frequency Band
Experience superbly detailed sound across a broad frequency spectrum. The Dynaquattro's three dynamic drivers, alongside a passive diaphragm, work harmoniously to produce an exceptionally clear and balanced sound. Each driver operates through its independent sound guide structure, complemented by a precisely engineered three-way frequency crossover. This setup ensures accurate sound reproduction, further optimized by a high-precision Klippel system, which meticulously fine-tunes the vibration modes of the diaphragms.
Enhanced Low-Frequency Performance
Delve into deep, impactful bass with the Dynaquattro's powerful 10mm dynamic driver. This large driver is designed with a composite dual-diaphragm, featuring a 10mm titanium dome-coated silicone grainless diaphragm and a 6mm wool paper cone passive diaphragm. Together, they deliver a crisp, detailed low-frequency response that adds depth and richness to your music.
High-Resolution Mid and High Frequencies
The Dynaquattro excels in delivering high-resolution sound in the mid and high-frequency ranges. The 6.8mm high-frequency driver features a high-rigidity aluminium diaphragm, providing well-defined and detailed high tones. Meanwhile, the 8mm midrange driver uses a cermet textureless diaphragm, constructed from lightweight yet durable metal, ensuring fast transients and crisp, clear output.
Precision-Crafted Frequency Crossover
Designed with precision, the Binary Dynaquattro incorporates a three-way physical frequency crossover. Each driver is connected to its independent acoustic tube, meticulously calculated and thoroughly tested to ensure superior sound delivery. This crossover system creates a rich, delicate, and well-layered audio experience, minimizing distortion and maintaining sound integrity across all drivers.
Elegant Design with CNC Machined Face Panels
The Dynaquattro isn't just about superior sound; it also boasts a stylish design. The CNC-machined aluminium alloy face panels draw inspiration from the four internal dynamic drivers, featuring industrial-grade patterns like gears and machinery motifs. These elements reflect Binary's commitment to professionalism, precision, and innovation.
High-Quality Silver-Plated Cable
Included with the Dynaquattro is a high-purity OFC (oxygen-free copper) silver-plated cable, equipped with an interchangeable termination plug system. This system includes both a 3.5mm single-ended and a 4.4mm balanced plug, ensuring versatility in connectivity. The universal 2-pin 0.78mm connectors allow for easy cable replacement, enhancing the longevity and adaptability of the IEMs.

I went to the store with to purchase aful P7 but ultimately bought dynaquattro Pritam was the big help in deciding the purchase he really understands the ones taste in music and recommends accordingly really happy with the purchase now for the iem dyna really shines in the base department but slightly lacks in the airyness you wont get timbre as much as compared to da vinchi but male vocals and bassy instruments really shines without fatigue and one can enjoy music for hours as there is little to no harshness in the tone if you like music like abhangs go for it without any second thought

OUR HONEST REVIEWS FROM THE CO-FOUNDERS & AUDIOPHILES
Absolutely bang for the buck. Best beginner IEM under 2000 Rs and I am not even kidding or exaggerating.
This is my second KZ EDC pro set actually. I ordered it for my brother because I like it a lot. If you want for gaming or on limited budget, definitely buy it. It can be driven buy any normal 3.5mm device, but buy a dongle DAC if you can it will enhance your experience with cleaner sound.
Read the detailed review below.
The tuning is lot balanced with slight V shape is how everyone describes it. So far from friends, I got to try Moondrop chu II, Tangzu Wan'er SG 2, Blon bl03 I, KZ ZSN pro X and KZ EDC pro(my own) all with DAC (for first three it was with Audiocular spark). I will say I prefer EDC pro over all of these. Might sound like a madlad here preferring a 700rs IEM over ~2000 rs IEM but it's just that good.
Tuning: It comes to preference, but what's good is it is not the usual KZ like tuning, and it's V shape enough to enjoy but not too much to crush all details. It's tuning is close to moondrop chu II I would say, and Blon bl03 if you reduce sharpness of the treble. Or other way to describe would be little more bass than Tangzu Wan'er SG 2. But it does feel little sharp sometimes on highest volumes with something like trumpets playing.
Technicalities: I am a noob, yes. But from my understanding, it's very head to head with tangzu wan'er SG 2 and blon bl03 in terms of soundstage. Well, in busy tracks seperation (I listen to J-pop a lot), all of the IEMs I tested so far have failed (the best set I could experience was Fiio ft1 pro open back, so my judgement of seperation and soundstage comes according to that). And a heads up, its sensitivity is high, so it will produce hissing noise with DACs that have Amp chip with higher noise flour than it's sensitivity.
Cons:
1. It starts to struggle at higher volumes, becomes little sharp (ear piercing treble) with things like trumpet, but again you will never require higher than 60-70% in quite listening.
2. Other IEMs in under 2k range have smaller sizes, this one is just way bigger in the ears, but due to that it's a snug fit. People with smaller ears will find it way bigger.
Thanks for reading!
Also thanks for the audio store team for cooperating about the Spark DAC hissing issue even when it was clearly my mistake. It seems it's not publicly known that IEM sensitivity should be checked before buying a dongle DAC+Amp.

Great headset for comfort and neutral sound with a hint of sharpness
Great headset for comfort and neutral sound. The headband is excellent and fits my large head with no issues and the pads are isolating and comfortable too. The sound is basically neutral, the bass is present and textured but not boosted by much. Mids are spectacular and tame but not recessed at all. The treble brings the mids out even more without harshness and is pretty well extended at least to the uppertreble. Air frequencies are somewhat subdued but still not a problem for the sound. The treble is just a bit emphasized as it's oriented for mixing, so for casual listening it's a little sharp but it's my preference that way. If you're okay with a set that brings out details through Treble you'll like this.

The Audiocular Spark Hi-Res portable DAC and amp is a compact
The Audiocular Spark Hi-Res portable DAC and amp is a compact, budget-friendly device powered by the flagship CX31993 DAC chip and MAX97220 amplifier, delivering studio-quality audio with clear vocals, rich bass, and detailed highs. It provides up to 63mW power output suitable for most IEMs and headphones, improving volume levels and sound clarity significantly over phone. Its solid build quality, portability, and seamless Type-C to 3.5mm compatibility, make it on-the-go music listening experience for me. Some minor background hiss may be audible with sensitive earphones, but overall it offers excellent value for a high-resolution audio upgrade at a very affordable price. This DAC+amp is very good option to be considered under 1,000 rupees, balancing sound quality, convenience, and durability effectively

In the budget category, these offers LDAC and planar magnetic drivers for truly clean, balanced sound and a unique design. It may have less extra features than other earbuds, but its core audio quality is far better than the usual bass-heavy options.
