Description
Advanced Dual Dynamic Drivers
The Truthear x Crinacle ZERO IEM features dual dynamic drivers with dual polyurethane suspension composite liquid-crystal dome diaphragm and N52 Rubidium magnet double-cavity internal magnetic circuit dynamic driver. This setup ensures exceptional sound quality and precise audio performance.
High-End 3D Printing Technology
Utilizing DLP-3D printing cavity technology, typically reserved for high-end multi-driver products and custom earphones, the ZERO is meticulously crafted with a hand-made glue-dropping and capping process. This advanced technology enhances durability and sound accuracy.
Superior Cable Quality
Equipped with a copper-plated silver cable featuring a thicker diameter single strand, the ZERO delivers outstanding objective indicators and ensures superior audio transmission. This high-quality cable enhances the overall listening experience.
Efficient Driver Configuration
The ZERO houses a dual dynamic driver configuration with one driver measuring 10mm and the other 7.8mm. This combination provides a smooth, soft, and detailed sound, thanks to the mature internal magnetic circuit structure and flexible polyurethane suspension composite LCP liquid crystal dome diaphragm.
Optimized Frequency Division
The 7.8mm dynamic driver handles mid-high frequencies with an ultra-fine CCAW voice coil, improving sensitivity and providing clean, delicate treble tones. The 10mm driver, responsible for low frequencies, uses a special weighted voice coil to reduce natural resonant frequency for accurate frequency division, delivering a full and vigorous bass response.
Precise Hybrid Frequency Division
Leveraging high-precision DLP-3D printing technology, the ZERO features an acoustic nozzle structure with filtering functions and an accurately calculated RC frequency division. This design ensures that both dynamic drivers perform optimally, meeting objective sound quality indicators.
Exceptional Sound Quality
The ZERO IEM achieves a balanced low-frequency gain and high-frequency response aligned with HRTF characteristics, making it comparable to professional monitor earphones. It provides a natural and atmospheric sound, avoiding the cold and rigid tones typical of common monitor earphones.
Consistent Full-Frequency Phase
A critical factor in multi-driver earphones is phase consistency. The ZERO's full-frequency phase is highly consistent, avoiding the convergence issues common in multi-driver earphones. This eliminates unnatural listening experiences caused by phase distortion.
Innovative 3D Printing and Medical-Grade Materials
Manufactured by HeyGears using DLP 3D printing and medical-grade high-transparency resin, the ZERO's cavity is lightweight, skin-friendly, and reliable. The internal coloring process and delicate acoustic nozzle structure enhance both aesthetics and functionality.
Durable Glue-Dropping Molding
The ZERO adopts a sandwich structure for its cavity, comprising a front cavity, decorative panel, and glue-dropping capping. The glue-dropping process, solidified and shaped by ultraviolet light, ensures a beautiful design and reinforced firmness, further processed by hand-polishing and varnish spraying.
Versatile and Expandable Cable
The ZERO includes four strands of high-quality silver-plated cable and a universal 0.78 2Pin interface. This configuration allows for excellent sound quality and expands possibilities by enabling cable changes, offering flexibility and customization for audiophiles.

from 5181 reviewsThe fitting and impact of sound quality and comfort is amazing I would love to buy more this kind of eartips
Most convenient

This was a gift for a friend of mine. The shipping took some time but when it reached them it was shipped the same day and after two days it was received. It came in perfect condition. I'll copy my friend's review below:
"This is most balanced IEM with a touch of warmth among everything out there. The Bass is just a bit much and with a 3db high-pass filter it became perfect. It doesn't get much better from this. The soundstage and imaging is decent and competes with +800$ stuff. The tuning, resolution and timbre is one of the best even under 2k. I'm very much in love with them. The comfort is pretty decent. I haven't got tired of them even after long hours."
The audio quality is very crisp and refreshing
The sound just amplified after using this with my kz castor pro IEMs....it is amazing.

Great product, strong magnet and holds the DAC snugly. Wish the 3M sticker was sold separately as well as already started to come off (user error).
the Detailed and balanced sound. then the design is so beautiful, the white version looks very good.
*What I liked the most:*
Clear sound at a volumes.
Good bass response, with focus on the sub-bass.
Tuning nozzles which make huge difference to the sound signature.
Good treble which is not harsh or sibilance.
Good soundstage & imaging performance.
Generous amount of ear tips to choose from.
High quality cable.
*Something that I didn't really like:*
Huge metal carrying case.
Ldac, hifi eq, durability, water proof rating
Quality

The amount you pay for this DAC is absolutely worth it. I'm using it with my PC, and I also have a Fiio KA13. It provides 32-bit 48000Hz audio output, and it's really good. I'm connecting it via a USB-C port and one extension cable (AGARO 3.5mm Aux Male to Female Extension Cable, Gold Plated). There’s no audio loss whatsoever.
The only minor issue is when you use it with a mobile device — the blue light can be a bit annoying. However, that's more of a personal preference. It also makes some noise with certain songs, but that's actually a known issue with the CS46L41 chip. There's no need to worry though; unless you've used a high-end DAC before, this will be more than enough for you.
Bass and clear vocals
😊
Excellent sound quality

After searching internet found this dac which has multiple input options and support 165*2 watts passive speakers and 350 watt passive subwoofer for future extension, tested with all input modes, bluetooth input feels a bit of low quality as it only supports sbc and aac codecs only, however if you want to use mobile via wired, alternative options 1. connect using Portronics Bridge Y USB 3.0 to Type C OTG Adaptor via USB A. 2. Use audiocular d08 cs-pro usb-c to 3.5 mm and 3.5 mm to rca input (cable creation brand). Optical input mode supports PCM (loss less stereo output) and Digital compress audio multichannel only) these are specific to Sony X-80J 65 inch
