Truthear x Crinacle ZERO:RED IEM
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.

OUR HONEST REVIEWS FROM THE CO-FOUNDERS & AUDIOPHILES
View allTRUSTED BY OVER 35K+ MUSIC ENTHUSIAST
Let customers speak for us
from 4979 reviewsI 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 👍

Best under 2k for balanced sound.

Rarely do you find cases that offer this kind of value. I love it for two main reasons: there's no need to cram your IEMs like in typical compact cases, and it has enough room to fit a dongle DAC comfortably. You can even carry two IEMs if needed. The build is solid, and it feels premium all around. A great pick!

Suggested by Pritam—bought them and loved them. Insane value for the price! A must-have for beginners exploring the tip rolling game. While they mimic some branded ones, the material and build do differ—but the value is unbeatable. Highly recommended!

Purchased a iem from them.Nice packing safe delivery. Will definitely recommend beginner audiophiles to buy it from them.
The overall earbuds are good with great design and good sound quality.
I loved the way it's made.
Wires interlocked creating a mesh-like texture that feels good.
There is 1 issue it feels very delicate. Wires used are very thin and i think on rough usage they can break.
The sound is magical.

I have KZ ZSN Pro X, CCA PLA 13, Zigaat Nuo & KZ ZS10 Original but this KZ ZS10 Pro X with upgraded drivers is.. Best overall!
Sound quality
Mids - Good vocals, Female vocals are better!
Highs: Sweet & Controlled Extension
Bass: Impact more than enough, subbass is excellent!
Soundstage : Good Depth & Height, bigger than KZ ZSN pro X
Separation: Brilliant Sonic performance, Best of all!
Quality : Better that original ZS10 PRO
Note: I burned in more than 70 hours
I am using wide bore tips for even better soundstage!
Thanks to The Audio store & KZ !
