Description
Advanced Dual Driver Configuration
The Truthear x Crinacle ZERO RED IEM adopts a dual polyurethane suspension composite liquid-crystal dome diaphragm with an N52 Rubidium magnet double-cavity internal magnetic circuit dynamic driver. This innovative driver setup ensures superior audio performance and precision.
High-End 3D Printing Technology
Using DLP-3D printing technology, typically reserved for high-end multi-driver products and custom earphones, the ZERO RED features a hand-made glue-dropping and capping process. This meticulous manufacturing technique enhances both the aesthetic and acoustic properties of the earphones.
Superior Cable Quality
Equipped with a copper-plated silver cable of a thicker diameter for each strand, the ZERO RED ensures minimal signal loss and outstanding audio quality. This premium cable construction enhances durability and sound fidelity.
Efficient and Rational Driver Configuration
The ZERO RED houses a dual dynamic driver configuration, featuring a 10mm driver and a 7.8mm driver. The flexible polyurethane suspension composite LCP liquid crystal dome diaphragm and a mature internal magnetic circuit structure ensure the RED offers superior objective indicators compared to the standard ZERO model.
Innovative Frequency Division System
The 7.8mm dynamic driver, responsible for mids and treble, uses an ultra-fine CCAW voice coil, providing a lightweight vibration system and smooth frequency response. The 10mm dynamic driver, responsible for bass, features an adjusted diaphragm structure for improved nonlinear distortion and bass response, ensuring accurate sound reproduction.
Accurate Hybrid Double Frequency Division
Utilizing high-precision DLP-3D printing technology, the acoustic nozzle structure with filtering functions, and an accurately calculated RC frequency division form a hybrid double frequency division system. This system allows each dynamic driver to perform optimally, achieving the design goal of precise objective indicators.
Excellent Objective Indicators
The RED model's R&D target is based on TRUTHEAR's original ZERO model, with further optimization of nonlinear distortion at higher sound pressure levels (>94dB). The frequency response curve provides bass amplitude response similar to the public preference curve, while the CRINACLE IEF_Neutral curve is used for frequencies above 1000Hz, ensuring a balanced and natural sound.
Consistent Full-Frequency Phase
The ZERO RED's full-frequency phase is highly consistent, eliminating the phase distortion common in multi-driver earphones. This consistency ensures a natural listening experience without the unnatural effects caused by phase issues.
Next-Generation 3D Printing and Medical-Grade Resin
The ZERO RED features a DLP 3D printing cavity made by HeyGears, utilizing medical-grade high-transparency resin and an internal coloring process. This ensures high printing accuracy, efficiency, and a lightweight, skin-friendly, and reliable cavity.
Optimized Processing Technology
TRUTHEAR emphasizes both excellent objective measurements and processing technology optimization. The ZERO RED's sandwich-like cavity structure, combined with 3D printing, hand-made polishing, and automatic gloss painting, results in an exquisite and durable faceplate.
High-Quality Cable and Flexibility
The ZERO RED includes a four-strand high-quality silver-plated cable and a universal 0.78 2Pin interface, allowing for excellent sound quality and flexibility through cable changes.

Let customers speak for us
from 5011 reviewsThe Sennheiser IE 200 delivers impressive value for the price. Comfort-wise, they’re lightweight and fit snugly thanks to the ergonomic design and included foam/silicone tips—great for long listening sessions. Build quality is solid despite the plastic housing, and the detachable braided cable adds durability. As for the sound signature, it’s balanced and clean—tight bass, clear mids, and smooth treble without harshness. Bonus points for the dual-tuning feature that lets you slightly tweak the sound. A fantastic entry-level choice for anyone looking to step into the audiophile world.
There sound is pretty good
Good quality
a very well made cable from Dunu with modular plugs and a very secure fastening system (q lock), no microphonics noted, contrary to many reports, usage : Shure se215 + 4.4 plug + Hiby r4 and it really opens up the Shures and the over ear loops are very comfortable too
This 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 👍
