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
They sound just amazing, I would say that the app a little rough to use. I can vouch they sound amazing. better than most of the tws which are out there in the market. Also, the Online dsp, gives a little edge it you want to tune them, and you can also upload your on DSP. Overall at this price point, It' a 10 on 10 deal.

Exceptional Sound with Balanced Bass
I’m genuinely impressed. The sound quality is exceptional—crisp highs, clear mids, and a bass response that’s just right. It doesn’t overpower the mids or muddy the overall sound, which is a rare balance to strike in this price range.
🎧 Sound Signature: Tuned to the Harman Target with a tasteful bass boost. It adds warmth without sacrificing clarity, making it perfect for everything from vocals to electronic music.
🔊 Bass: Not too high, not too low—just enough to give depth without distortion. It complements the mids beautifully.
🛠️ Build Quality: Solid and premium-feeling. The fit is comfortable for long sessions, and the mic is a handy addition for calls or gaming.
Overall, it’s a fantastic value for the price. If you’re looking for an IEM that delivers refined audio with a touch of bass and excellent build quality, this one’s a winner.

This was my first purchase from The Audio Store and I have to say the experience was excellent. Right from placing the order to the delivery (which was handled by Bluedart), everything went smoothly. I also had a few queries about IEMs in general, so I reached out to them on WhatsApp. The reply was quick, clear, and exactly what I was looking for. Really helpful! Overall, I’m very happy with the experience and would definitely recommend The Audio Store to anyone looking to buy IEMs or any other audio gear.
