If you want a wired in-ear monitor built around a dual dynamic driver setup and a replaceable cable, choose TRUTHEAR x Crinacle Zero; if you need lightweight on-ear headphones with a USB-C plug and an inline mic for calls, choose AIAIAI Tracks White USB-C. That is the short version. The long version comes down to one question: do you want something that lives in your ears and treats sound as the priority, or something that sits on your head and treats everyday convenience as the priority? I would pick the TRUTHEAR for listening and the AIAIAI for living with. Read on, because the two products barely share a target buyer.
• TRUTHEAR x Crinacle Zero — biggest strength: A dual dynamic driver design with a DLP-3D printed cavity, a glue-dropped and hand-polished cap, and a four-strand silver-plated cable on a 0.78 2Pin socket you can swap out. In my opinion, the sound-first engineering is the whole point.
• TRUTHEAR x Crinacle Zero — biggest trade-off: No microphone, no inline controls beyond a wired remote, no noise control, and a 3.5 mm jack. It is for listening, not for talking.
• AIAIAI Tracks White USB-C — biggest strength: A lightweight aluminium headband, 40mm drivers, a USB-C audio plug, a three-button remote and a built-in mic. Everything you need for a laptop or phone with no headphone jack.
• AIAIAI Tracks White USB-C — biggest trade-off: An on-ear supra-aural fit and a 20 KHz frequency response ceiling. It is a convenience-first headphone, not a detail-chasing monitor.
• Who each pick is for: TRUTHEAR for the listener who wants the cable, the fit and the tuning to be the star. AIAIAI for the commuter, student or remote worker who wants one cable, one button row and a mic.
The TRUTHEAR x Crinacle Zero is an in-ear monitor, and it is unapologetic about that. The headline is the driver arrangement: a dual dynamic driver setup using a polyurethane suspension composite liquid-crystal dome diaphragm with an N52 magnet and a double-cavity internal magnetic circuit. That is a lot of engineering language, but what it means for a buyer is simple — two drivers doing divided work rather than one driver trying to cover everything. The acoustic nozzle has a filtering function and the crossover is a hybrid double frequency division, so the low end and the rest of the range are handled separately.
The second thing worth understanding is the shell. TRUTHEAR uses a DLP-3D printed cavity, the kind of process usually reserved for high-end multi-driver models and custom earphones, paired with a glue-dropping capping process that is cured with ultraviolet light and then hand-polished and varnish-sprayed. The practical payoff is a lightweight cavity with a sandwich structure — front cavity, decorative panel, capped shell — that holds its shape and stays skin-friendly. The nozzle geometry is the sort of fine detail that traditional molding struggles to reproduce.
On tuning, the claim in the spec sheet is a low-frequency gain and high-frequency response that follows HRTF characteristics, which TRUTHEAR positions as objective performance comparable to professional monitor earphones without the cold, rigid character those often have. Full-frequency phase consistency is called out too, which matters because phase issues are the classic failure mode of multi-driver designs. The frequency range runs 20Hz to 39500Hz and impedance is 10 ohm, so these are easy to drive from a phone or a dongle. The 0.78 2Pin socket with a sunken female connector means you can change the cable later — a four-strand silver-plated cable ships in the box, and the included carrying case is red while the earpieces are blue.
Buy it if you want an in-ear monitor you can cable-swap, you care about driver architecture and phase, and you mostly listen rather than talk.
Skip it if you need a microphone for calls, you want USB-C without an adapter, or you dislike things sitting inside your ear canal. There is no active noise control here, and the wired remote is basic. This is a listening tool.
The AIAIAI Tracks White USB-C is a supra-aural — on-ear — headphone with a deliberately minimal look. The spec sheet describes a lightweight aluminium headband, simple lines and an iconic shape, plus a customizable slider with a choice of two colours. That slider detail is small but telling: this is a product designed to be worn out in the world, not locked in a studio.
The audio side is a 40mm dynamic driver with a full-spectrum tuning described as tight bass and detailed high frequency notes. The frequency response tops out at 20 KHz and impedance is 32 ohm. Those are sensible, real-world numbers rather than exotic ones. The point of this headphone is not to win a measurement contest — it is to sound good enough on a train, at a desk, or on a walk, without fuss.
Where the AIAIAI genuinely pulls ahead is connectivity and control. It terminates in USB-C, which matters enormously if your laptop, tablet or phone has dropped the 3.5 mm jack. There is a three-button remote for music control and a microphone for calls, so you can take a meeting or answer a call without pulling anything out of your ears. Button control rather than touch means no accidental skips when you adjust the fit.
Skip it if you want isolation, deep bass extension, or a replaceable cable. On-ear headphones leak sound and let sound in. There is no noise cancellation, and the 20 KHz ceiling tells you this is not a detail-extraction tool.
Side-by-Side: Which Should You Choose?
• Best for sound-first listening → TRUTHEAR x Crinacle Zero. Dual dynamic drivers, a hybrid double frequency division, and a tuning explicitly aimed at phase consistency across the range.
• Best for calls and meetings → AIAIAI Tracks White USB-C. It has a microphone and a three-button remote; the TRUTHEAR has neither.
• Best for modern laptops and phones → AIAIAI Tracks White USB-C. USB-C plugs straight in. The TRUTHEAR needs a 3.5 mm jack or an adapter.
• Best for cable longevity and upgrades → TRUTHEAR x Crinacle Zero. The 0.78 2Pin socket with a sunken connector lets you replace or upgrade the cable.
• Best for long wear without ear fatigue → AIAIAI Tracks White USB-C. An on-ear aluminium-band design sits outside the ear canal, while an in-ear monitor demands a proper seal.
• Best for isolation from the outside world → TRUTHEAR x Crinacle Zero. A sealed in-ear fit blocks far more ambient noise than an on-ear headphone, even without active noise control.
• Best for portability → TRUTHEAR x Crinacle Zero. In-ears and a case disappear into a pocket; on-ear headphones do not.
• Best for low-impedance, easy-to-drive use → TRUTHEAR x Crinacle Zero at 10 ohm, versus 32 ohm for the AIAIAI. Both are easy, but the TRUTHEAR is easier.
• Best for a minimalist look → AIAIAI Tracks White USB-C. Simple lines, aluminium band, and a two-colour slider choice.
In my opinion, the TRUTHEAR x Crinacle Zero is the more interesting product and the one I would buy for myself. The dual dynamic driver architecture, the phase-consistency work, the DLP-3D printed shell and the swappable 0.78 2Pin cable add up to a piece of gear that rewards a listener who cares about how it is built and how it is tuned. The 10 ohm impedance means it will run off almost anything.
That said, I would not recommend it to everyone. If your laptop has no headphone jack, if you spend your day on calls, or if you simply hate things in your ear canal, the AIAIAI Tracks White USB-C is the smarter purchase. It is light, it is minimal, it plugs straight into USB-C, and it has the mic and buttons the TRUTHEAR lacks.
Two different jobs. Pick the one that matches yours. And check the current price on Amazon for whichever you land on, since that is the only variable that changes here.
For gaming, I would lean TRUTHEAR. The in-ear seal cuts ambient noise, the phase consistency helps positional cues, and the 10 ohm impedance is easy to drive from a controller or a dongle. The AIAIAI's on-ear fit leaks sound both ways, which hurts immersion.
Yes. It has a microphone for calls and a three-button remote for music control, and it connects over USB-C. The TRUTHEAR x Crinacle Zero has no microphone, so if talking is part of your day, that decides it.
Yes. It uses a universal 0.78 2Pin interface with a sunken female socket in the cavity, and ships with a four-strand silver-plated cable. That means you can swap cables later for fit, length or preference. The AIAIAI's cable is not described as replaceable.
I do not quote prices here because they change. Check the current price on Amazon for both. On value, it depends on use: the TRUTHEAR gives you more acoustic engineering per unit, while the AIAIAI gives you USB-C, a mic and buttons — features the TRUTHEAR simply does not have.
