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!

OUR HONEST REVIEWS FROM THE CO-FOUNDERS & AUDIOPHILES

Let customers speak for us
from 4996 reviewsThis is really warm sounding as advertised. Especially vocals are more engaging. The fact that its driven by phone power doesn't affect the sound quality in anyway like in other dacs I have experienced brighter, thin sound or few peaks in upper midrange. If earphones are having good sensitivity then this dac provides good enough power. Although bit bulky build is very good. I'm sure it can withstand frequent drops also. Have not tried the filters and listening to default filter only. One thing I noticed is although on paper power output is good for 32ohm its only good at driving earphones and not headphones. Distortion kicks in when volume is increased even at high gain setting. I'm only guessing current supplying capability for dynamic driver headphones is not sufficient. Tested with 300ohm HD600.
The sound quality is so much better than any other wireless earphones
The quality of wire is superb.
The mic quality is also good.
Length and feel of wire is good. Sound quality with my Tangzu warner is excellent

Have bought this on 17 Aug 2024 and after using it for almost half a year i can surely say this is the best one in this price range...
I like how crisp and clear the audio is, also how good the IEMs respond to EQing, which unlocks a lot whole lot of possibility

Recently bought this after seeing some positive reviews
Fit:
Unlike many reviews which talks about it's fit issue, it's a wonderful fit for me with the stock large size narrow bore tips. I usually go for medium or small size silicone tips but for this one large one fitted well. i guess large size long stem eartips fits well with this iem.
Sound:
Vocals and string instruments sounds forward but never thin or sharp or fatiguing and has a sweet timbre. I guess it's due to its thick note weight and the quality of dynamic driver.
Bass in general is good. But i would prefer little bit more sub bass quantity. Also prefer the bass to be a bit tighter. Not too tight as i am not a fan of too tight bass. Basically here bass decay is slow and i would prefer it to be moderate.
Treble has just enough energy and details but relaxed.
Overall it sounds very nice with a pleasant timbre.
Note that i replaced the stock cable with fiio ls-b 4.4 mm cable.

Great set to start your tip rolling journey!
Got the delivery under 24 hrs.

This is wonderful product and quality is great. Very good working with mic.
And support samsung s22 ultra.
The Moondrop Blessing 3 is a hybrid IEM with excellent performance and a largely neutral sound signature with a slight bass boost. It offers impressive detail retrieval, resolution, and instrument separation for its price.
Pros:
* Excellent detail and clarity: It reveals subtle nuances in music.
* Balanced sound: Largely neutral with a well-controlled bass that doesn't bleed into other frequencies.
* Good technicalities: Strong imaging and separation of instruments.
* Comfortable for wearing for long periods
* Solid build quality
Cons:
* Fit can still be an issue for those with smaller ears.
* The cable could have been better.
Overall an excellent IEM for me.... Well done Moon drop!!!
The KZ ZSN Pro 2 offers exceptional sound quality at an affordable price. With a hybrid driver setup (1 dynamic + 1 balanced armature), it delivers a punchy V-shaped sound signature with deep bass, clear mids, and sparkling highs. The soundstage is surprisingly wide with good instrument separation and imaging. Build quality is solid, featuring metal faceplates and a comfortable, ergonomic design. While the cable and accessories are basic, the overall performance makes the ZSN Pro 2 a fantastic value for budget audiophiles.
Yes it is very comfortable 👍

Best under 2k for balanced sound.

Rarely do you find cases that offer this kind of value. I love it for two main reasons: there's no need to cram your IEMs like in typical compact cases, and it has enough room to fit a dongle DAC comfortably. You can even carry two IEMs if needed. The build is solid, and it feels premium all around. A great pick!

Suggested by Pritam—bought them and loved them. Insane value for the price! A must-have for beginners exploring the tip rolling game. While they mimic some branded ones, the material and build do differ—but the value is unbeatable. Highly recommended!

Purchased a iem from them.Nice packing safe delivery. Will definitely recommend beginner audiophiles to buy it from them.
