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.

Customers praised these audiophile-grade IEMs for "excellent sound across all music genres" and gaming. Many noted superior quality compared to premium alternatives. Some found treble bright initially, requiring EQ adjustments. Fit varies by ear size, with limited tip compatibility for some. Cable with mic rated lower quality than standard cable. Overall, "best all rounder for the price."
Yeah, IEMs are new for me, so I'm getting into them slowly. I like the sound quality, but at first, it was too loud. I tried every ear tip to find a match, and only one pair fit my ears, so I'm using those. The treble was a bit much, so I adjusted the EQ, and now it's fine. The earbuds are a bit big for my ears, but it's okay now. I do miss the warm, bassy sound output I get from my Sony WF-1000XM4, but I like this IEMs because they offer better sound quality than the Sony WF-1000XM4.
This IEMs delivers excellent sound across all music genres and is used daily. The unboxing experience is premium. However, a minor issue has been identified: the right-side IEM produces a subtle noise when tapped while worn, which may indicate a manufacturing defect.
these are perfect, he difference btween these and air pods is fargrreater. buy it. make sure to buy a dac amp as well.
Great quality audiophile’s for gaming.
.......
But very excited to try this iem
The supplied cable with mic seems to be of lower quality than the one without the mic. Sonically its too good.
These are good.
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.
best all rounder for the price, good for gaming and music

Pairing this Harman Target Version with a Samsung A17 playing Apple Music and FLAC files and Fiio X1 DAP as a secondary source with FLAC files. When tuned to give preference to Mids as i prefer to hear the voices more than anything else, this comes out as a sweet sounding combination and tracks like Racy Chapmans Fast Car and Massive Attacks Teardrop shine beautifully. The Castor Pros are best listened at about 40% volume and and infact they do actually sound amazing at a high volume for bass heavy tracks such as EDM but for Trance and Rock the cymbals and snare drums sound better at 40%. This pair of iems and the combo sounds like money well spent so far and next i want to try analytical IEMs like the 7Hz. Thanks to the Audio Store for the rushed delivery.
Great purchase... excellent product
Good Product as expected
Worth every penny! This is not for bassheads as it lacks just a bit on the bass department, but the separation is awesome and the sound stage is also huge. Awesome for gaming as well! (Apex Legends, Arc Raiders, PUBG)
This is the replacement for my purchase of moon drop dsp chu2 which I bought in aug 2025 i don't know how it got damaged from last it stopped working on left side buds and after a few days mic also stopped working and i forgot to claim the warranty for it . So find this spare cable very helpful since I love these IEMS for real Tq AUDIO STORETEAM FOR THE smooth delivery
Great job on packing of the product. As a gamer I can say that, for fps games like PUBG , CS2 etc., Castor Pro is the best in under ₹2000
I recently bought this and am incredibly impressed with it. The build quality feels solid and premium right out of the box.
When it comes to performance, the amplification is fantastic—it delivers a clear, noticeable boost to the audio power and volume without sacrificing clarity. It is also incredibly easy to use; completely plug-and-play with zero hassle.
An awesome bonus is the inclusion of the Type-A to Type-C dongle/adapter. It makes it incredibly versatile to connect to different devices right away without needing to buy extra accessories.
Overall, it's a great purchase and definitely worth the money. If you are on the fence, just get it!
As an all rounder it fits my taste quite well,the only problem it really has is the male vocals being a bit recessed (not terribly recessed if you use vocal eartips),they are a tad bit overpriced seemingly,divine planar might be better,but for people looking for a fun entry into iem's,it's worth the price (some people say it's included DAC isn't enough,it works well enough as a temporary solution,yet to test if a dac makes a big difference or not).
Unsure if this is how most iem's are but the cable felt a tad bit short.
I had never used an IEM before, so this was my very first experience and I was genuinely impressed. As someone who loves music, I can confidently say this is one of the best investments you can make for audio quality. The sound is exceptional and absolutely worth the price.
To get the best possible audio experience, I would also recommend pairing it with a good-quality DAC, as it significantly enhances the overall output. ....
This is the most balanced sounding IEM I've used in this price. I am using the Type C variant, and I haven't experienced any issue regarding the playback whatsoever. It is equipped with the DAC chip CX31993, which is found on the dedicated DACs around the price of 1K. The cable is also a 4-core silver plated copper one, with really nice build quality. These are also really responsive to EQ Settings, tweaking the audio balance using a 10 or 31 band EQ makes the experience even more versatile.
The only cons I have noticed are regarding the in-box ear tips, I didn't find them to be very comfortable, so I had switch them with some other ear tips. Although, the metal built of the IEMs give them a really premium feeling, the glossy surface is extremely prone to scratches and they still get scratched even after using cautiously.
It is best in budget dac.
Save money get this dac-amp
It is good but could be a bit sharp sometimes may be balanced by EQ. But one problem in my type C unit, after 3 days it stop sound out of nowhere, while listening music, or watching movie/yt. Have to plug out plug in to get the audio back.
This is a magical DAC, I don’t believe ki isne mere headphones main jaan daal di ho
Really the quality of aurora ultra is out of the box , literally if you never use an iem and experience first time you feel actual music. Aurora ultra give life best experience.
This is only possible because of the audio that my first experience and the audio store surve there best to just create my best experience thanks a lot for protective, timely delivery and
Again thanks for giving that service and seamless experience to the team
