• ooopusX Op.24 — biggest strength: a hybrid 2-dynamic-driver + 4-balanced-armature setup with a physical dual-mode tuning dial, so one earphone covers two distinct sound profiles instead of locking you into one.
• ooopusX Op.24 — biggest trade-off: it's a wired Type-C in-ear with a fixed 0.78 2-pin cable, so it demands an in-ear fit and a USB-C source — no analog jack, no wireless.
• AIAIAI Tracks White USB-C — biggest strength: a clean, minimal on-ear design with 40mm dynamic drivers, an aluminium headband and an inline three-button remote plus mic for music and calls.
• AIAIAI Tracks White USB-C — biggest trade-off: it's a single tuning with no user adjustment, and on-ear pads sit on the ear rather than sealing inside it, so isolation and bass depth are more modest by design.
• Pick the ooopusX Op.24 if you want maximum driver count, tunability and a proper in-ear seal for focused listening.
• Pick the AIAIAI Tracks White USB-C if you want something you can wear all day, plug into a phone or laptop over USB-C, and use for calls without thinking about it.
The Op.24 is the more technically ambitious of the two. Inside each shell you get two dynamic drivers — a coaxial 10mm plus an 8mm — working alongside four balanced armatures in a three-way hybrid architecture. That's six drivers per side, which is a lot of hardware for a single earphone, and the point of that arrangement is bandwidth coverage: the dynamic units handle the low end while the balanced armatures take the mids and highs. The spec sheet puts frequency response at 10Hz–40kHz, THD under 1% at 1kHz, and sensitivity at 127dB/Vrms.
What separates it from most hybrid IEMs is the tunable acoustics dial. A physical dual-mode switch pairs with an internal dual-channel electronic crossover, so you can flip between two voicings on the fly rather than swapping earphones or fiddling with an EQ app. The impedance figure tells you what's happening electrically: 15Ω in Mode 1 and 27Ω in Mode 2. Lower impedance generally means an easier load for a phone or dongle to drive, so Mode 1 is the friendlier everyday setting, while Mode 2's higher impedance suggests a slightly different balance and possibly a touch more headroom needed from the source.
Buy it if you're the type who listens critically, wants to hear the difference a crossover makes, and likes gear you can adjust. The silicone composite carbon fiber dome diaphragm and oxygen-free silver-plated cable point at a listener who cares about materials, and the included eartips and one-year manufacturer warranty cover the basics. It ships as a Type-C model with a mic, so it works for calls too.
AIAIAI Tracks White USB-C: Who It's For
The Tracks is the opposite philosophy: keep it simple, keep it light, keep it wearable. It's a supra-aural (on-ear) headphone built around 40mm dynamic drivers, with a frequency response quoted to 20kHz and 32Ω impedance. That impedance is a middle-of-the-road figure — neither unusually easy nor unusually demanding — which is consistent with a headphone designed to plug straight into whatever USB-C device you own and just work.
The design is the headline. A lightweight aluminium headband keeps the weight down, and the customisable slider comes in a choice of two colours so you can add a small personal accent. The whole thing leans on simple lines and an iconic silhouette rather than flashy materials. It's a look that reads as deliberate minimalism, and the aluminium band is the one piece of obvious premium hardware in the build.
Functionally, the USB-C plug, three-button remote and built-in microphone turn it into a do-everything headphone: pause and skip tracks, take a call, get back to your podcast. Push-button controls mean the interaction is physical and predictable. Because it's on-ear rather than in-ear, you don't need to fuss with tip sizes, and you can pull one cup off to hear someone talking to you without fully removing the headphone.
Buy it if you want one wired headphone that lives on your desk or in your bag and handles music, video calls and casual listening without any setup. The tight-bass, full-spectrum tuning described for the 40mm drivers suits pop, electronic and podcast content well.
Skip it if you need serious isolation for a noisy commute or an open-plan office, or if you want to change the sound signature. There's one tuning here, and on-ear pads leak and let sound in by nature. Skip it too if you want deep sub-bass slam — that's a job for a sealed in-ear.
Side-by-Side: Which Should You Choose?
• Best for driver count and hybrid design → ooopusX Op.24. Two dynamic drivers plus four balanced armatures per side, versus one 40mm dynamic driver per side on the Tracks.
• Best for frequency range on paper → ooopusX Op.24. 10Hz–40kHz versus a quoted 20kHz ceiling.
• Best for calls and quick control → AIAIAI Tracks White USB-C. A three-button remote and mic on the cable, with push-button controls you don't have to look at.
• Best for all-day wear and easy fit → AIAIAI Tracks White USB-C. An on-ear design with a lightweight aluminium headband means no tip-seal guessing and no deep-insertion fatigue.
• Best for a minimal, customisable look → AIAIAI Tracks White USB-C. Simple lines, an aluminium band and a two-colour slider option.
• Best for critical, quiet-room listening → ooopusX Op.24. An in-ear seal plus hybrid drivers is the setup that rewards attention.
• Best for low-impedance, dongle-friendly use → ooopusX Op.24 in Mode 1. At 15Ω it's the easier electrical load; switch to 27Ω Mode 2 when you want the alternate voicing.
In my opinion, the ooopusX Op.24 is the more interesting product and the one I'd buy. The hybrid six-driver architecture and the physical tuning dial give you two genuinely different sound profiles in one earphone, and the 10Hz–40kHz response and sub-1% THD figures suggest the engineering effort went into the acoustics rather than the packaging. If you listen deliberately — at a desk, in a quiet room, with a USB-C source — it rewards that attention. I'd only steer you to the AIAIAI Tracks White USB-C if convenience and all-day wear matter more than adjustability: it's the calmer, more comfortable, call-ready choice, but it's a single fixed tuning. Check the current price on Amazon for both before you commit, since the value call depends on what each costs on the day.
Not universally — it's better on driver count, tuning flexibility and quoted frequency range. The Tracks is better on wearability, fit simplicity and built-in call controls. It depends on whether you prioritise sound adjustment or everyday convenience.
No. Nothing in the spec sheet mentions active noise cancelling. They're on-ear headphones, so expect only mild passive isolation, and some sound leakage in and out.
Yes — it's sold as a Type-C model with a mic, and the low 15Ω Mode 1 impedance makes it easy to drive from a phone, laptop or dongle. The hybrid drivers and wide frequency response suit game audio and voice chat.
The AIAIAI Tracks White USB-C, in my view. Its lightweight aluminium headband and on-ear pads avoid the tip-seal and insertion issues that come with any in-ear, including the Op.24.
