Looking for a budget in-ear monitor that punches above its weight? The TRUTHEAR x Crinacle Zero has spent the last few years as one of the most recommended entry points into the hobby, and it still holds that position on merit. This dual dynamic driver IEM pairs a Harman-influenced tuning with a dedicated bass driver, giving you deep low-end weight without smearing vocals or detail.
Developed as a collaboration between TRUTHEAR and the reviewer Crinacle, the Zero uses a 10mm dynamic driver setup, a 10-ohm impedance load, and a detachable 0.78mm 2-pin cable. It’s a wired earphone with a 3.5mm plug, so it works with phones, laptops, desktops, and portable DACs alike.
- Glue-Dropping Molding Capping Process: ZERO whole cavity adopts a sandwich structure (front cavity, decorative panel, and glue dropping capping); ZERO is capped by glue-dropping process and it is solidified and shaped by ultraviolet and processed by hand-polishing and varnish spraying, which ensure beautiful design while effectively reinforce the firmness processed by glue dropping capping
- Age range descriptionAdult
- Excellent Objective Indicators: ZERO has a proper low-frequency gain and high-frequency response in line with HRTF characteristics, which makes ZERO own the objective index comparable to that of professional monitor earphones, while it is not as cold and rigid as that of common monitor earphone, and its overall timbre is natural and full of atmosphere
The resin shells arrive with a generous set of eartips, a carrying pouch, and a cable that most listeners find perfectly serviceable. For anyone stepping up from stock phone buds or cheap wireless earbuds, the jump in clarity is immediate.
Bottom Line
The Zero remains one of the safest recommendations under the $60 mark, offering balanced tuning, real sub-bass extension, and a replaceable cable that extends its life.

TRUTHEAR x Crinacle Zero Overview
Two dynamic drivers per side handle the frequency range, with one dedicated to bass and sub-bass duties while the other covers mids and treble. That division is the core of what the Zero does well at its price.
The shell is built with a sandwich construction: a front cavity, a decorative faceplate, and a UV-cured resin cap that’s hand-polished before finishing. The result is a smooth, lightweight housing in blue and black.

Dual Dynamic Drivers and Bass Impact
Sub-bass extension is the headline feature here, and it comes from a driver doing nothing else. Low notes hit with physical texture rather than a vague warmth spread across the midrange.
Kick drums land with definition. Electronic tracks with deep synth lines reproduce the rumble you’d expect from far more expensive gear.
The separation keeps vocals clean even when the bass is working hard. Listeners coming from single-driver budget IEMs notice this immediately, since bloated low end is the usual compromise at this price.
Rock and acoustic material benefits too, with bass guitar lines sitting distinctly under the mix. If you want a leaner presentation, the Moondrop Aria 2 takes a different approach to the same budget bracket.
Natural Tuning and Everyday Listening Detail
Frequency response follows HRTF-informed targets, which means the treble sounds correct without the clinical edge some monitoring earphones carry. Cymbals and string harmonics come through with air, not sizzle.
Vocals sit forward enough to stay engaging across pop, jazz, and singer-songwriter recordings. Female vocals in particular avoid the shoutiness that plagues cheaper V-shaped tunings.
Instrument separation holds up at moderate complexity. Dense orchestral passages compress somewhat, which is expected in this class.
Long sessions stay comfortable on the ears because nothing in the upper mids fatigues you. That balance is a large part of why the Zero keeps appearing on recommendation lists years after release.
Shell Design, Cable, and Long-Term Comfort
Fit is the most polarizing part of the package. The nozzle is on the wider side, and listeners with smaller ear canals report needing to experiment with tips or swap in third-party options.
The shells themselves are light and contoured, with a smooth resin finish that avoids pressure points during multi-hour use. Once you land on the right tip size, they disappear.
The detachable 0.78mm 2-pin cable is the practical highlight. When a cable fails, you replace it instead of the earphones, which is a meaningful advantage over sealed budget earbuds and wireless models.
The included pouch is soft rather than rigid, so pocket storage requires a bit of care.
Pros and Cons
Pros
- Dedicated bass driver delivers deep, textured sub-bass without muddying vocals
- Tuning follows HRTF-informed targets for natural timbre across genres
- Detachable 0.78mm 2-pin cable makes replacement easy and extends product life
- Lightweight resin shells stay comfortable through long listening sessions
- Wide selection of included eartips helps most users find a seal
- Low 10-ohm impedance drives fine from phones and laptops
Cons
- Wide nozzle diameter causes fit issues for smaller ear canals
- No inline microphone on the stock cable
- Soft carry pouch offers limited crush protection
- Complex, layered recordings can sound slightly congested
- Wired-only design with a 3.5mm plug requires an adapter on many modern phones
What Customer Reviews Reveal
Buyer feedback across thousands of ratings clusters around one theme: the sound quality reads as far more expensive than the asking price. Reviewers who describe themselves as non-audiophiles report an obvious step up from stock phone earbuds and mid-tier wireless models.
Gamers mention strong positional imaging, with several noting good results when paired with a mixer or hardware EQ. Owners a year or more into use report the earphones holding up without issues.
Fit is the recurring complaint. Multiple reviewers describe difficulty with insertion depth or removal, and a few mention needing to cycle through tip sizes before settling.
International buyers echo the same points, praising accessory quality, the tip selection, and bass depth from the second driver. A handful of reviewers weigh the Zero against similarly priced competitors and land on it as the safer all-rounder.
Conclusion
The Zero earns its reputation as a default budget recommendation because it gets tuning fundamentals right and adds a bass driver that most competitors in this range skip. Sub-bass depth, natural vocal reproduction, and a replaceable cable form a package that stays relevant years after launch.
Check the nozzle diameter against your ear canal size before committing, and budget a few dollars for aftermarket tips if you’ve had fit trouble with wide-bore IEMs before. If you need a microphone for calls, plan on a separate 2-pin cable with inline controls.
For desktop listening, gaming, and portable use with a dongle DAC, this remains one of the strongest entry points into wired audio. Browse more of our reviews for alternatives at higher price tiers.
Frequently Asked Questions
Is the TRUTHEAR x Crinacle Zero good for gaming?
Yes, the Zero performs well for gaming thanks to solid positional imaging and a clean midrange that keeps footsteps and voice chat distinct. Owners pairing it with mixers like the Astro MixAmp report good results, especially with EQ adjustments applied.
How does the TRUTHEAR x Crinacle Zero differ from the Zero?
The Zero is a later revision with a warmer, slightly less bass-forward tuning aimed at listeners who found the original too sub-bass heavy. Both use the dual dynamic driver layout and the same 0.78mm 2-pin connector, so cables and tips carry over.
Does the TRUTHEAR x Crinacle Zero have a microphone?
No, the stock cable ships without an inline microphone or remote controls. Because the 2-pin connector is a common standard, you can buy a third-party 0.78mm cable with a mic if you need call functionality.
Are the TRUTHEAR x Crinacle Zero earphones comfortable for small ears?
Comfort depends heavily on ear canal size, since the nozzle is wider than average and some buyers report insertion or removal difficulty. The shells are light and well-contoured, so smaller-bore aftermarket tips resolve the issue for most people who struggle initially.
Do the TRUTHEAR x Crinacle Zero need an amplifier?
No amplifier is required. With its 10-ohm impedance, the Zero is easy to drive from phones, laptops, and portable players.
A dongle DAC can help if your device lacks a 3.5mm jack, and it provides a little extra headroom for quieter recordings.
