If you want wired in-ear earbuds with a noise-isolating, bass-driven fit that tucks inside a helmet for motorcycle riding, choose erjigo in-Ear Earbuds Headphones; if you need on-ear headphones with a USB-C plug, an inline mic and a three-button remote, choose AIAIAI Tracks White USB-C. That's the short version. The long version is that these two aren't really competing for the same buyer at all — one is a 3.5mm in-ear monitor-style earbud, the other is a USB-C on-ear headphone built around calls and control. If your headphone jack is a phone with no jack left, or your laptop only does USB-C, that single difference decides it before anything else does.
• erjigo's biggest strength: a 10mm dynamic driver tuned for bass-forward, noise-isolating in-ear listening, with a light metal-and-resin housing that's designed to sit still for long stretches.
• erjigo's biggest trade-off: it's a 3.5mm wired bud with no microphone and no inline call controls — great for listening, useless for taking a call.
• AIAIAI's biggest strength: USB-C audio plus a three-button remote and a mic, so you get playback control and hands-free calls from a single cable.
• AIAIAI's biggest trade-off: it's an on-ear, open-feeling design — it won't seal your ear canal the way an in-ear bud does, and it won't fit under a helmet.
• Choose erjigo if you want in-ear isolation, deep bass and a cable that resists tangling, and you're plugging into a standard 3.5mm jack.
• Choose AIAIAI if you want on-ear comfort, a USB-C connection, and a microphone for calls and voice chat.
The erjigo set (model CRA) is a classic wired in-ear. The core of it is a 10mm dynamic driver paired with a high-polymer diaphragm — the spec sheet describes a light, thin, high-elasticity composite, and that's the recipe for lively, punchy low end rather than a flat studio tone. The tuning is explicitly bass-driven, and the in-ear seal is what makes that land: because the tip sits inside the canal, it blocks a good chunk of outside noise before the music even starts. For a rider, that isolation is the whole point. An in-ear that seals means you can hear your music at a sane volume instead of cranking it to fight wind noise.
So who should buy it? Anyone who wants an in-ear that stays put, sounds bass-heavy, and isolates. Riders, commuters, gym-goers, people who plug into a 3.5mm jack and don't want batteries involved. Who should skip it? Anyone who needs a microphone. The listing is explicit: this version ships without mic. If you take calls, this isn't your set. And if your only output is USB-C, you'll need an adapter.
AIAIAI Tracks White USB-C: Who It's For
AIAIAI's Tracks USB-C is a different animal. It's a supra-aural (on-ear) headphone with a lightweight aluminium headband and a customisable two-colour slider — a deliberately minimal, design-forward piece. Inside are 40mm dynamic drivers rated at 32Ω with a stated 20kHz frequency response, tuned for what the specs call tight bass and detailed highs. That's a full-spectrum on-ear sound rather than an in-ear thump.
The real story here is connectivity and control. The cable terminates in USB-C, not a 3.5mm plug, and there's a three-button remote plus a microphone built in. That combination is what makes this a genuinely practical headset: play/pause, track skip, volume, and voice calls all from the inline module. If you're on a laptop or a newer phone that lives on USB-C, this eliminates the dongle entirely — and it's exactly the kind of setup people search for when they want usb c charging bluetooth earbuds for motorcycle, except this one is the wired, zero-battery version of that idea. No charging case, no pairing, no dead earbud halfway through a ride.
The trade-offs are real, though. On-ear means on-ear: the pads rest against your ear rather than sealing the canal, so isolation is lighter than any in-ear can offer. The aluminium band is light, but it's still a headband — it does not fold into a helmet. And there's no battery, no ANC, no wireless mode. It's a wired headset, full stop.
Side-by-Side: Which Should You Choose?
• Best for motorcycle use → erjigo in-Ear Earbuds Headphones. The in-ear form factor fits under a helmet and seals out wind noise; the on-ear AIAIAI physically won't.
• Best for taking calls → AIAIAI Tracks White USB-C. It has a mic and a three-button remote; the erjigo set has neither.
• Best for bass-forward, isolated listening → erjigo. The 10mm bass-driven driver plus canal seal delivers more low-end impact than a supra-aural on-ear.
• Best for USB-C devices with no headphone jack → AIAIAI. USB-C termination means no adapter needed; erjigo needs a 3.5mm port or a dongle.
• Best for long-session comfort without pressure → erjigo. The lightweight cavity and memory ear hook are designed to reduce stress over long wear.
• Best for a light, design-led on-ear with a replaceable-feeling slider → AIAIAI. Aluminium band, two-colour customisable slider, minimal lines.
• Best if you hate tangles → erjigo. The OFC flat parallel cable is specifically built to resist knotting.
• Best if you want zero batteries or pairing → both. Neither needs charging; both are fully wired.
For motorcycle riding specifically, I'd buy the erjigo in-Ear Earbuds Headphones. In my opinion, the sealed in-ear fit and bass-driven tuning are what actually work under a helmet — the AIAIAI on-ear simply can't go there. If your priority is calls, a mic, and a USB-C connection for a laptop or phone, flip it and take the AIAIAI. Check the current price on Amazon for both before you commit, since that's the one thing that could still change your mind. My pick for the rider: erjigo.
For the erjigo set, yes — the in-ear design seals the canal and the bass-driven tuning holds up against road noise, and it fits under a helmet. The AIAIAI is an on-ear headphone, so it's not a realistic helmet option.
No. This specific version is listed as "without mic," so it's for listening only. If you need calls, that's the AIAIAI's job — it has a built-in mic and a three-button remote.
The erjigo uses a standard 3.5mm jack, so it plugs into anything with a headphone port (or a dongle). The AIAIAI uses USB-C, which suits phones and laptops that dropped the headphone jack — but it won't fit a 3.5mm socket without an adapter.
On paper, the erjigo is the bass-focused pair: a 10mm driver explicitly tuned for bass-driven sound, with a sealed in-ear fit that reinforces low end. The AIAIAI's 40mm drivers are described as tight bass with detailed highs — fuller and wider, but not as thumpy.
