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.

TRUSTED BY OVER 60K+ MUSIC ENTHUSIASTS
Let customers speak for us
Good for:
>Vocal dominated tracks (general bollywood songs)
>Indian classical in vocal. string and wind instruments, acoustic guitars.
> Western classical focused on Piano, violin and cellos (e.g. Ludovico Einaudi, Lang Lang)
Need a little twigs in eq:
> Female vocal may need 2-3 db boost in at around 2k region.
> Old tracks designed for tapes and cassettes generally has treble boosted in default. Hence a 1-2 db pull down in 8k &16k band makes it more enjoyable (e.g track - Nahi samne from movie Taal)
Not good for:
> Heavy rock and metals that demands more throbbing base.
> Heavy electric guitars mainly power chords & overdrive base guitars sounds muddy.
> Lacks wide sound stage required for large and dynamic orchestral pieces. Like cornfield chase by Hans zimmer, Nostalgia by Yanni
> Hip-hop and Electronic tracks lacks the attacks and punchiness
VERDICT:
> Deep and tight base, buttery soft mids and well defined and perfectly rolled out treble that doesn't heart your ears after a while.
>Go for it if you are a bollywood song lover. You can't get anything better, at least at this price brakets.
> Shines well with Sigma-delta dacs but feels bit too warm for r2r Dacs. Although some people can prefer that. But do not use it with a very powerful amp. Personally I felt opamp like MAX97220 is more than enough.
> Base is deep and tight. So do not buy this if you want thumpy base.
> Not a flat responding iem. So do not consider it if you want an analytical piece. > Choose it if you are looking for long listening sessions with deep imotional attachment rather than analytical detailing.
I've been using this IEM for a couple of days now, and compared to the Moondrop CHU II, the treble feels noticeably improved.
Majestic sounding IEMs worth every penny
Good
best dac ever used the sound is incredibly good amazing the black colour is currently on top
Love it! My swimming sessions have become much more enjoyable and consistent. I also love listening to audiobooks and retro songs on these when not in water! Good product for a healthy lifestyle
KZ Duonic ka sound sach me bhut acha hai aur iski overall quality kamal ki hai. planar driver hone ki wajah se clarity next level milti hai. Bass tight hai aur instrument separation bhi bohot clear hai. Isme music suno bohot acha experience hota hai . Highly recommended if you love high-resolution audio!
It just works amazing with all of my audio products
These my first iems using it from last 2 months very nice very balanced sound
A beautiful pair of iems at this price range. Balanced sound, but engaging listening. Also good for monitoring.
Really good DAC and perfect for apple devices as it does not reduce the volume like few other DACs..and very good delivery experience from TAS..👍🏻
Various reviews on the net created a lot of desire and interest to possess this iem.
Hitherto iv been buying audio gear from some other website who did not have this iem in stock.
Thought of buying from Audiostore.
I spoke to Mr Pritam and finalised the deal. Personal interactions do add up to the textual.content you gather from the net. Delivery was exactly as promised.
My first impression of the iem is Spectacular sound reproduction!!!
Songs thatIheardliterallyfelt like being played in front of me.
Bass sufficiently good enough for every listener except bassheads. Of course bassheads would lose considerable amount of ther sonic capabilities.
Soundstage wide and imaging is excellent. Inspite of good bass every instrument is distinctly clear and precise.
Only request for Audiostore is to include other leading brands like Fatfreq, Fiio, Ibasso etc.
My honest review these are best and luxury looking IEMS and I love them and they fit in my ear perfectly for me and I love them
This IEM sound really good for everyday listening. The Bass has a nice punch,Vocals come through clear and the overall sound feels balanced and enjoyable.They’re comfortable to wear for long periods and block out a decent amount of outside noise.Easy to carry around as it’s comes with a pouch and Great for Music,Videos.Definitely worth it for the price, and specifically thanks for audiostore team.❤️❤️.
The bass in these stays present and hits quickly. An easy term to describe the feel is cinematic bass. And it get loud very fast recommend use Low gain with high volume or High gain with Low volume. Prefer your your choice.
After 10 days of use, I feel I made a great upgrade from the 7Hz Elua Ultra. The main differences are that the Elua has laid-back vocals and sub-bass rumbling, while the STA Hi-End surpasses those limitations with good imaging, zero distortion at high volumes, and cinematic punch in the sub-bass.
Here is the detail review with help of claude to differentiate the same batch of IEM just at "ONE POINT"
