How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an ultra-light in-ear monitor with a replaceable cable and a sound signature built for detail and speed, choose NALMOPG TRN MT1; if you need an on-ear headphone with an inline mic, a three-button remote and a USB-C plug for calls and daily listening, choose AIAIAI Tracks White USB-C. These two are barely in the same category — one is a wired IEM aimed at people who care about driver design, the other is a minimalist on-ear built for plug-and-play use with modern phones and laptops. My pick depends entirely on how you listen, so here is the honest breakdown.
• NALMOPG TRN MT1 — biggest strength: a dual-magnet 10mm dynamic driver paired with a 5μm silicon-crystal composite biocellulose diaphragm, which the spec sheet says raises magnetic flux by 55% (close to 1 T) for better resolution, dynamics and speed.
• NALMOPG TRN MT1 — biggest trade-off: it's a 3.5mm no-mic IEM. No remote, no microphone, no USB-C, so it's a listening-only tool.
• AIAIAI Tracks White USB-C — biggest strength: 40mm drivers with a USB-C audio plug, three-button remote and built-in mic — one cable for music and calls.
• AIAIAI Tracks White USB-C — biggest trade-off: it's on-ear and wired, so it won't isolate like an IEM and it depends on a USB-C port being available.
• In-ear detail and cable longevity → NALMOPG TRN MT1. Everyday calls and modern devices → AIAIAI Tracks White USB-C.
The TRN MT1 is a classic budget-minded IEM built around one interesting idea: a dual-magnet dynamic driver. According to the specs, that magnet design increases magnetic flux by roughly 55%, approaching 1 T, which the brand credits with improvements in resolution, dynamics and speed. In plain terms, that's engineering aimed at making the driver react faster and cleaner — the kind of thing that matters if you listen to busy, layered music where you want to pick out individual instruments rather than just hear a wall of sound.
The other half of the story is the diaphragm. It's a 5μm silicon-crystal composite biocellulose diaphragm, which the spec sheet claims is twice as efficient as a conventional biocellulose diaphragm. The practical takeaway: it's easy to drive. With 22Ω impedance and 106dB sensitivity, it should reach usable volume straight off a phone or a cheap dongle, no amp required. Frequency response runs 20Hz–20KHz, which covers the full audible range on paper.
Who should buy it: anyone who wants a lightweight, wired, in-ear monitor with a replaceable cable, easy phone-friendly driveability, and a driver design focused on detail and transient response. Who should skip it: anyone who takes calls on their headphones, wants USB-C, or needs a microphone — this model has none of that.
AIAIAI Tracks White USB-C: Who It's For
The AIAIAI Tracks is a different animal entirely. It's a supra-aural (on-ear) headphone with a deliberately minimal design — simple lines, an iconic shape, and a lightweight aluminium headband. It's the kind of product that looks as much like a design object as it does a listening tool, and the customizable slider with a choice of two colors reinforces that.
On the audio side, you get 40mm dynamic drivers with a full-spectrum sound that the spec sheet describes as tight bass with detailed high-frequency notes. Impedance is 32Ω, which is still low enough to run from a phone or laptop without extra gear. Note that the listed frequency response tops out at 20KHz — no extended treble numbers here, just a straightforward full-range figure.
The real differentiator is the cable end: USB-C. That means no dongle, no adapter, no 3.5mm jack hunt. It plugs straight into modern phones, tablets and laptops. Along the same cable you get a three-button remote for music control and a microphone for calls — controlled via push buttons. That combination is what makes this a daily-driver headphone rather than a specialist listening tool. You answer a call, skip a track, adjust volume, all without touching the device.
The trade-offs are inherent to the format. On-ear headphones sit on the ear rather than sealing into the canal, so isolation is limited compared to an IEM — you'll hear more of the room. And because it's wired USB-C, you're tethered, and you need a USB-C port that supports audio. Color is listed as Black in the item details while the style name is Tracks USB-C White, so expect the white variant with the black/aluminium detailing.
Who should buy it: commuters, remote workers and students who want one wired headphone for music, video calls and meetings, with a mic and remote built in and a modern USB-C connection. Who should skip it: anyone who needs strong passive isolation, prefers a 3.5mm jack, or wants a compact in-ear they can pocket.
• Best for detail and driver engineering → NALMOPG TRN MT1. Dual-magnet driver, 5μm composite diaphragm, 22Ω/106dB.
• Best for calls and remote work → AIAIAI Tracks White USB-C. Built-in mic and three-button remote on a USB-C cable.
• Best for modern devices without a headphone jack → AIAIAI Tracks White USB-C. Straight USB-C, no adapter needed.
• Best for old-school 3.5mm gear → NALMOPG TRN MT1. Standard 3.5mm jack with a 2-pin replaceable cable.
• Best for cable longevity → NALMOPG TRN MT1. 2-pin gold-plated connectors mean you can replace the cable instead of the whole set.
• Best for isolation and staying put during movement → NALMOPG TRN MT1. Over-ear hook fit with an ear-shaped shell for passive isolation.
• Best for a lightweight, minimal design object → AIAIAI Tracks White USB-C. Aluminium headband and customizable two-color slider.
• Best for low-weight all-day wear → close call, but the TRN MT1 is 8.2g per earpiece plus a 12g cable, while the Tracks is an on-ear with a light aluminium band. Different comfort styles, not a clear winner.
If I had to pick one, I'd buy the AIAIAI Tracks White USB-C — but only because my listening is tangled up with calls, video meetings and a laptop that has no headphone jack. USB-C audio, a mic and a three-button remote in one cable is simply more useful to me day to day, and 40mm drivers with tight bass and detailed highs are a sensible, unfussy signature.
That said, if you mainly listen to music and want the most interesting driver engineering for the money, I'd point you to the NALMOPG TRN MT1. The dual-magnet driver, the efficient composite diaphragm and the replaceable 2-pin cable are genuinely thoughtful choices at this end of the market. In my opinion, that's the better pure-listening pick.
FAQ
Yes, as long as your laptop has a USB-C port that supports audio. It connects via USB-C directly, with no 3.5mm jack or adapter involved. If your device only has a headphone jack and no USB-C audio, the TRN MT1 is the better fit.
The NALMOPG TRN MT1, in my opinion. Its over-ear hook design and ear-shaped shell sit inside the canal and provide passive isolation, and the spec sheet also lists active noise cancellation. The AIAIAI Tracks is on-ear, so it sits outside the canal and lets more of the room in.
