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 4809 reviews
i think it's a great choice for someone who's just starting with the "iem" audiophile thing and it sounds good pretty good for the price range, it's sound clear and crisp, the bass is a little on the lower side but nonetheless great product if you are just starting, oh and yes the delivery was fast got it in a day.

Delivery was fast and item received was in good condition

Lets get to the point, its the best budget IEM!
I have been in the IEM space for more than 6 months and I was looking for a daily driver that can handle rough use, and then Pritam Sir suggested me 7Hz G1. And it failed to disappoint me!
A nice high quality well built iem, with one of the best ergonomic design, and a proper sound isolation with tons of tip to choose from.
The iem is well tuned with proper instrument seperation and clarity, warm tuning with perfect bass and excellent soundstage compared to other budget IEMs.
If you are new to yo IEM and want to buy your first IEM, blindly go with this! Trust me you would not regret! For 3.2k, its a steal deal!
(Pro Tip: Always listen to Pritam Sir's suggestions. He is the G.O.A.T)

We had an amazing experience at The Audio Store. Pritam, the shop expert, was incredibly helpful and knowledgeable. He patiently guided us through the world of in-ear monitors, explaining all the details and helping us understand what would work best for our band, Rhythm Freak. He suggested options that perfectly matched both our budget and our musical needs, making sure we got the best value without compromising on quality. Thanks to his expertise, we walked out confident and satisfied with our purchase. Highly recommend this store to any musician looking for top-notch gear and excellent service

Sound quality ausom but not for base lover's

Top notch earphone Mike quality 🔥.gaming, music etc highly recommend ❤️🎧

I believe this is the best tws under 10000 rupees also it is an iem

Thank you audio store. The sound is amazing. It was delivered within time and product was perfect.

Very detail iem for the price not bass heavy

It is compact and yet have a good punch to the output it gives, the packaging was very impressive for the price.

Twilight from Soft Ears seems to me like a benchmark for single DD IEMs. The solid metal craftsmanship is commendable and when it comes to the sound, tonality, song signature and quality is presently benchmark for Single DD IEMs, may be rivalled by the Elder turii ti, which cost 3x of this.

I would really recommend these. I previously used KZ Castor, but these IEMs are a major upgrade. The sound division is really good. The only issues are low bass and high treble. If you want a more balanced or v shape, it is better to use an equaliser. I am using these with Fiio K1 and Audiocular X Tiandirenhe CS-PRO DACs. Both give a nice output.
I don't know if this is specific to Apple Music or IE 200, but when I push the music through an equaliser, I hear a crackling sound (only on hi-res, 24-bit/192 kHz). I will maybe test more on this and will update the review.
Finally, I would recommend it. These IEMs are worth the buck.

One of the best dac amp in budget category, it gives balance output that going well with my performer 8.

It's an interesting product. I like all the tip options in this pack. It's a good beginner pack to know how each tip material can affect the sound quality. All the tip material & quality are good. The silicone tips & foam tips in the pack are good, like those stock tips we get with IEM. But the surprising tips are the latex tip & the hybrid foam tip. Although the latex tip feels a little rubbery in feel & is a dust magnet, but it's very comfortable, provides a good seal and does enhance bass & treble response slightly. And for the hybrid tip, it's like best of both worlds. It gives the comfort of a silicone tip as well as provides the seal of a foam tip. I'm not a big fan of foam tip in general because of how they feel in ear & it's very difficult to put them in the ear, but these hybrid tips removed all those problems for me.

This is one of the best modular cables I have ever seen in this price range. Microphonic is there as the nylon type of material is used for wrapping the cable. But microphonic is very minimal compared to other similar cable I have used. But, once the music starts playing, the microphonic would be gone. connector quality is very premium, on both the 3.5 / 4.4 termination as well as at 2-pin connector end. I love how easy is to replace the 3.5 & 4.4 end. It's highly recommended if you are looking for any premium modular cable on budget. It's one of my favorite modular cables along with the Moondrop aria 2's stock modular cable.
