Truthear x Crinacle ZERO:BLUE2 IEM – Dual Dynamic Drivers, Refined to Perfection
Experience the evolution of precision audio with the Truthear x Crinacle ZERO:BLUE2 – an in-ear monitor crafted for audiophiles who demand accuracy, clarity, and balance across the frequency spectrum. This second-generation collaboration with Crinacle builds upon the legacy of the original ZERO, offering significant upgrades in driver architecture, frequency response, and overall sound performance.
Dual Dynamic Drivers with Upgraded Architecture
The ZERO:BLUE2 features an advanced dual-dynamic driver system with a 10mm solid silicone suspension LCP dome (N52 magnet) for deep bass and a newly refined 7.8mm polyurethane suspension LCP dome (N55 magnet) for crisp mids and detailed highs. This dual-cavity magnetic circuit design achieves a remarkable increase in sensitivity and upper-frequency resolution, allowing you to hear subtle recording details with lifelike accuracy.
Optimized Frequency Crossover & Tuning
Engineered with a hybrid multi-frequency crossover and low-distortion circuitry, ZERO:BLUE2 ensures smooth transitions between frequency ranges. The filtered nozzle, manufactured with HeyGears’ precision DLP 3D-printing, enhances acoustic performance while supporting a well-balanced soundstage. Expect punchier bass, transparent mids, and extended treble response with outstanding clarity.
Enhanced Driver Efficiency & Objective Measurements
With a 25% larger magnet and 50% larger dome on the 7.8mm driver, ZERO:BLUE2 achieves higher conversion efficiency and superior high-frequency sensitivity. Objective measurements show reduced nonlinear distortion and a more accurate frequency curve aligned with human hearing (HRTF), resulting in vivid sound reproduction and a natural listening experience free from phase distortions.
Durable, Lightweight Shell with Ergonomic Comfort
Built using high-end 3D-DLP printing technology, the shell is lightweight yet robust, with a redesigned faceplate and improved nozzle geometry for better fit and comfort. The skin-friendly cavity ensures fatigue-free listening, even during extended use.
Upgraded Silver-Plated Cable with Optional Mic
ZERO:BLUE2 includes a premium silver-plated copper coaxial cable with a 0.78mm 2-pin connection, offering better durability and improved conductivity. The bundled version also includes a high-quality oxygen-free copper microphone cable, perfect for gaming, calls, and live monitoring, delivering versatility without compromising audio fidelity.

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.

Works well with my Moto Edge 50 Pro. Other DAC's would have a lot of interference and static, the Moondrop Echo A has none. Audio is clear and the connector does not heat up at all. Battery life isn't impacted as well.
The build quality is excellent, cable is flexible and will fit in any iem carry case as well.

This is a great product with excellent sound quality. The bass is impressive and it's worth the money.

Beautiful and heavy duty balanced cable. Adds a weight to the music's bass i.e. tighter bass response.
Good product excellent sound well packed but delivery was delayed by two days.otherwise everything good.

Combo of cx31993 max97220 chip is more than sufficient to drive any iems

Using it with truthear crinicle zero red and works perfectly. Loving it

I’ve been thoroughly impressed with the SMSL RAW MDA-1, especially as someone who values Hi-Res audio and the transformative power of a great DAC+amplifier.
The build is solid, with a sleek, compact design that fits perfectly on my desk without taking up too much space. I love the variety of connectivity options—USB-C, coaxial, optical, and Bluetooth—making it easy to connect to my PC, gaming console, or even my phone. The Bluetooth feature is particularly handy for wireless listening when I want to move around without sacrificing sound quality.
One thing I’ve found is that it’s exceptionally well-suited for low to medium impedance headphones, delivering plenty of power and clarity. However, if you’re using high-impedance headphones, you might notice it struggles a bit with volume, so you may need an external amplifier for those. Also, while the 4.4mm headphone output is convenient, it’s not a true balanced design, which might be a letdown for audiophiles who prioritize that feature.
Given its price point, the SMSL RAW MDA-1 offers exceptional value, delivering high-end features and performance that punch above its weight class. It is particularly suitable for audiophiles and gamers seeking a high-quality desktop audio solution with both wired and wireless options. However, for those with high-impedance headphones or a preference for advanced sound-shaping features, it may fall short, potentially requiring supplementary equipment.

KZ Castor Harman Target with Improved Bass is just bliss for listening to music & watching movies.
