How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired in-ear monitor built for detail, isolation and gaming positional cues, choose Linsoul 7Hz; if you need an on-ear headphone with a USB-C plug, a mic and inline controls for calls and everyday listening, choose AIAIAI Tracks White USB-C. These two look like they compete for the same buyer, but they really don't. One is a metal-shell IEM tuned for critical listening; the other is a lightweight, plug-and-play on-ear headphone built around a USB-C connection. Pick the wrong one and you'll fight your own gear every day.
• Linsoul 7Hz biggest strength: a metal-and-plastic rounded in-ear shell with a dynamic driver covering a full 20Hz–20,000Hz range, plus a 3.5mm wired connection — proper isolation and deep bass extension in a tiny package.
• Linsoul 7Hz biggest trade-off: it's a 3.5mm analog IEM with a remote control but no microphone for calls, so it's a listening tool, not a headset for meetings.
• AIAIAI Tracks White USB-C biggest strength: USB-C audio, a three-button remote and a built-in mic, with 40mm drivers and a lightweight aluminium headband — one cable that handles music and calls.
• AIAIAI Tracks White USB-C biggest trade-off: it's supra-aural (on-ear), so it doesn't seal or isolate like an IEM, and it's a single USB-C connection with no 3.5mm fallback.
• Who each pick is for: Linsoul 7Hz for gamers, musicians and detail-focused listeners who want an in-ear seal. AIAIAI Tracks White USB-C for people on USB-C devices who want a comfy on-ear headset for music and calls.
The Linsoul 7Hz is a wired in-ear monitor, and everything about its design points at that job. You get a rounded-tip earpiece shape that sits inside the ear canal, a metal-and-plastic enclosure in silver, and a dynamic driver rated across 20Hz to 20,000Hz. That frequency range tells you the low end is meant to reach down properly — useful when a track has real sub-bass, or when a game throws footsteps and distant engine noise at you and you need to place them. The in-ear shape is the whole story here: because the tip sits in the canal, you get passive isolation from the room around you. That's why IEMs like this get picked up by musicians monitoring on stage and by gamers who don't want a fan, a keyboard or a chatty room bleeding into their ears.
The connection is a 3.5mm jack, wired, with a remote on the cable. That's a flexible, universal setup — it plugs into controllers, laptops, audio interfaces and phones that still have a headphone port, and it's the kind of analog connection that doesn't care what operating system you're running. The included OFC IEM cable is there to keep the signal path clean, and the metal-and-plastic shell means it can take being shoved in a pocket or a case without feeling fragile.
Who should buy it? If you're a gamer chasing positional audio, a musician who wants a cheap-and-capable monitor, or a listener who genuinely prefers the isolation and bass extension of an in-ear, this is the shape of product you want. Who should skip it? Anyone whose laptop or phone has no 3.5mm jack at all, and anyone who needs a microphone for calls — the remote controls playback, but this isn't a headset, and I wouldn't buy it expecting to take meetings on it. If you dislike things sitting in your ear canal for hours, an on-ear design will treat you better.
The AIAIAI Tracks White USB-C is an on-ear (supra-aural) headphone, and its headline feature is right in the name: a USB-C audio plug. That single decision changes who it's for. Modern laptops, tablets and phones increasingly ship with USB-C and nothing else, so a headphone that terminates in USB-C is a genuinely convenient thing — no dongle, no adapter to lose. Alongside the plug you get a three-button remote for music control and a microphone for calls, which turns it into a real headset rather than just a listening device.
The audio side is built around 40mm dynamic drivers, described as full-spectrum with tight bass and detailed highs, at 32 ohms impedance and a frequency response up to 20kHz. Bigger drivers in an on-ear enclosure generally mean a wider, more open presentation than a tiny in-ear driver can manage — you trade the deep seal of an IEM for a more spacious, out-of-your-head feel. The 32-ohm impedance figure suggests it's not a hard load to drive, which fits the "plug it into your device and go" pitch.
Build-wise, AIAIAI keeps it deliberately simple: a lightweight, minimal aluminium headband and a customisable slider with a choice of two colours, in a design the brand describes as subtle, with simple lines and an iconic shape. Note that the spec sheet lists the colour as black even though this model is named Tracks White USB-C — worth checking the product page if exact colour matters to you. Who should buy it? Anyone living on USB-C devices who wants one cable for music and calls, plus people who find in-ear tips uncomfortable and prefer something that rests on the ear. Who should skip it? If you need strong noise isolation or a 3.5mm connection for older gear, this isn't the one — on-ear headphones leak and let sound in, and there's no analog fallback here.
• Best for gaming and positional audio → Linsoul 7Hz. The in-ear seal and full 20Hz–20,000Hz dynamic driver are made for hearing where sounds come from.
• Best for calls and meetings → AIAIAI Tracks White USB-C. It has an actual microphone and a three-button remote; the Linsoul's remote doesn't include a mic.
• Best for USB-C-only devices → AIAIAI Tracks White USB-C. Native USB-C audio, no adapter required.
• Best for older gear and controllers → Linsoul 7Hz. The 3.5mm jack plugs into almost anything analog.
• Best for isolation → Linsoul 7Hz. In-ear tips block room noise; on-ear headphones don't.
• Best for long-session comfort if you hate things in your ears → AIAIAI Tracks White USB-C. The lightweight aluminium headband and on-ear fit suit that preference.
• Best for bass depth in a tiny package → Linsoul 7Hz. A sealed in-ear design reaches lower than an on-ear typically can.
• Best for a wide, open soundstage → AIAIAI Tracks White USB-C. Bigger 40mm drivers in an open on-ear cup.
If I had to pick one for myself, I'd take the AIAIAI Tracks White USB-C. In my opinion, the USB-C plug, the built-in mic and the three-button remote make it the more useful single purchase for most people in 2026 — it handles music and calls on the devices we actually carry, and the lightweight aluminium headband suits long sessions. That said, I'd recommend the Linsoul 7Hz without hesitation to gamers, musicians and anyone who wants isolation and deep bass extension from an in-ear. Decide which of those two lives is yours, then check the current price on Amazon for the one that fits.
Yes — in my opinion it's the better pick of these two for games. The in-ear seal and 20Hz–20,000Hz dynamic driver help you place footsteps and directional cues, and the 3.5mm jack plugs straight into most controllers.
Yes. It includes a microphone for calls plus a three-button remote for music control, which is the main thing it has that the Linsoul 7Hz doesn't.
No. Its connection is USB-C only, so devices without a USB-C port would need an adapter — that's a real limitation if you also want to use older analog gear.
The Linsoul 7Hz, because its in-ear design physically blocks more external noise. The AIAIAI is on-ear, so it isolates less and lets more of the room in.
