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.
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.

V-shaped IEM
Bright-sounding with good bass and treble. Silicone tips can feel harsh for some. Indian instruments sound very good with silicone tips, though. Foam tips minimize harsh sound, and bass is reduced too. Overall happy with purchase.

Probably the best IEM you can get for 2500
Build quality is top notch. It's heavy but not uncomfortable. Coming to sound it has balanced sound signature with slight emphasis on treble.

Best for the budget (~929 rs)
I was using Sennheisers CX80s with Samsung Galaxy A52s and it has 3.5 mm jack but the sound quality & output levels are very bad. So, I had to get a DAC and I watched a lot of reviews before making this purchase and one thing I can say is the sound quality is better than Apple's dongle becoz it only supports 16/44.1-48KHz .
The cable is super flexible and supports both Type C & Type A connection for PCs.

Summary review of the Mega5Est
These IEMs have a unique personality and it does match the many YT reviews that I watched before making this purchase.
The tuning is very neutral leaning slightly bright. These IEMs will present all instruments and everything that is present in the mix without emphasizing. Bass and sub bass present without any mud or overpowering of other frequencies. Mids are well presented, in fact these are all about the mids which are mostly neglected in favour of bass tightness and extended treble.
I found the vocals slightly forward but not harsh, in fact nothing is overpowering in the presentation here which may come across as boring but it is simply presenting the songs as is. You can easily drift off mentally while listening, the presentation is so neutral and focus back whenever you wish to.
Overall these are very solid IEMs good for analysing and casual listening both. Tuning preferences may be highly personal and there may obviously be many who may not prefer this kind of tuning but still this doesn't take any points away.
I am happy with the purchase and prompt delivery.
