Description
Advanced Dynamic Driver Configuration
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
Improved my listening experience
Fantastic sound quality!

Adequate purchase, best sound you will hear.
Probably double volume than TWS.
Looks seriously different than other headphones I have used till now, you look different than rest of the crowd(in the gym especially), that makes you feel special 😊☺️

Must go for it Bluetooth & DAC AMP

- Audiocular SPARK DAC is one of the best looking dongle DAC I can find also the audio quality it throws it's just supirior to any normal phone or pc DAC.
-Well there is lot of DAC with same configuration but on higher price this one feels premium and it's just under 1000 bucks so I don't think so you need anything else as a beginner or anywhere for regular use it's best of best.

- I was really confused between salnotes zero 2 and moondrops chu 2. After lot of thinking and chatgpt decided to go for Chu 2 well my initial experience was not good because I was using realme airbuds 5 pro which is a great wireless earphone dual drivers but mostly bass heavy so chu 2 bass felt lacking at start but it's just initial expression once I got comfortable with it is blown my mind cause it's really well balanced you can hear good amount of sound seperation bass is good and don't leak into the other instrument details or vocals.
- I purchased it with audiocular spark DAC
And honestly it's deadly combo it improves so much sound quality and bass and on top of that the fit of chu 2 and cable is really good and with this DAC it feels aesthetically pleasing as well.

Awesome headset
It was such a great MP3 player for the price. There was enough space as 32 GB memory card was provided. Also, we can read e-books in text format. It's so convenient during travel. FM radio is also present. Lot's of features in that small gadget ❤️.

The ear tips are good for starters and do have variety so I'm sure you'll find something comfortable. It can revive your interest in your old IEM's don't expect much as they are just there to deliver comfort to your ears.
New experience with the iem
Amazing sound very addictive ear phones might have been perfect if they came with c type connector
Build quality and audio clarity

Kudos to makers/seller for making it to available.
Purest form of audio hearing experience with this cable.
Happy with the purchase.

The build quality of this cable is top-notch. I’m using it with my HD560S connected to a laptop via Apple Music, and the difference is noticeable. The bass feels tighter and especially welcome improvement for openback headphones and there's a clear boost in instrument separation and overall clarity. Upgrading to a balanced connection has definitely proven to be a worth while decision.

The Hisenior Mega5EST is a reference-quality IEM tuned with taste and subtlety. It doesn't shout for attention but rather invites you to listen deeper. If you're looking for an IEM that balances technical excellence with musical emotion, this one is a rare gem in the hybrid space. A true “listen for hours, forget the gear” experience.

This is the best MP3 player you can get for this price.

I'm new to the world of IEMs and this one was bought to try how it feels. Trust me, it won't disappoint you. Double the value compared to headphones of the same rate.

Budget king SMSL RAW MDA1. Very versatile music dac & headphone amp. Fully satisfied. Being an audiophile I was searching for best budget one got this from The audio store. Thanks for timely delivery. Nothing can match it at this price range period.
