If you want an everyday wired earbud for calls, school and Chromebook or laptop use — with a mic, mute and in-line controls right on the cord — choose ASKUBSKU 3.5mm; if you need a wired in-ear monitor built for serious music listening, gaming and stage or studio work, choose Linsoul Kiwi Ears Belle.
• ASKUBSKU 3.5mm biggest strength: a practical, do-everything 3.5mm earbud — in-line controls, a mute function, a high-sensitivity mic and three sizes of silicone eartips in a semi in-ear shape.
• ASKUBSKU 3.5mm biggest trade-off: it's a general-purpose headset, not a tuned monitor. Metal housing and a purple finish, but no claim of measured channel matching or low distortion.
• Linsoul Kiwi Ears Belle biggest strength: a purpose-built IEM — a 10mm DLC dynamic driver, 32 ohm impedance, 103 dB sensitivity, under 0.1% THD at 1kHz, individually measured and paired drivers, and a two-core silver-plated cable.
• Linsoul Kiwi Ears Belle biggest trade-off: the "Without MIC" version has no microphone and no remote, so it can't take calls or trigger a voice assistant — it's for listening and monitoring only.
• Who ASKUBSKU 3.5mm is for: students, commuters and work-from-anywhere users who need one cheap-feeling-simple cord for calls, classes and Kindle Fire or laptop audio.
• Who Linsoul Kiwi Ears Belle is for: audiophiles, gamers and music makers who want an accurate, engaging monitor and already own a phone, DAC or interface to plug it into.
The ASKUBSKU 3.5mm is best understood as a utility headset. Its headline feature isn't exotic driver tech — it's the in-line control module, which lets you pause and play, answer and hang up calls, wake your voice assistant and mute the mic without touching your phone. The microphone is described as high-sensitivity and multi-directional, tuned to lift voices for clearer calls. For someone taking classes on a Chromebook, joining meetings on a laptop or listening on a Kindle Fire, that combination is the whole point.
The fit story is also clearly aimed at long sessions. You get three sizes of soft silicone eartips (L, M and S), and the buds use a 45-degree semi in-ear angle that the brand says reduces ear pressure and stops the buds from falling out. The metal housing and purple finish are a nice touch at this level, and the sound is a HiFi stereo tuning with a dynamic driver covering 20 Hz to 20,000 Hz. Noise isolation here is passive sound isolation rather than active cancellation, so it reduces background noise rather than erasing it.
Who should buy it: anyone who wants a simple wired 3.5mm earbud with a mic and controls, plugs into phones, laptops, tablets and handhelds, and doesn't want to think about impedance or DACs. Who should skip it: if you're chasing reference-grade detail, measured channel balance or a cable you can swap, this isn't that product — the Belle is. One practical note from the brand itself: if the buds ever stop working, check and clean the device's 3.5mm port, since dust and static-attracted debris there are the usual culprit.
The Belle is a different animal entirely. It's an in-ear monitor built around a 10mm Diamond-Like Carbon dynamic driver — a diaphragm material the brand notes has been proven in the IEM world for over a decade, with newer manufacturing improving rigidity and tension. The result, as Kiwi Ears describes it, is a snappy, responsive driver with the accuracy needed for music production and gaming. The numbers back the pro angle: 32 ohm impedance, 103 dB sensitivity, and less than 0.1% THD at 1kHz.
The tuning is deliberately not neutral-flat. Kiwi Ears describes heavy bass and warm mids balanced by a precise 3kHz pinna peak, which is why they pitch it as versatile across genres — deep and punchy for hip-hop and pop, lush in the midrange for male vocals, with a natural treble curve that pulls out micro-details without turning harsh. That's an "exciting but still precise" signature, which is exactly what makes it work for both casual listening and monitoring.
Build and quality control are where the Belle justifies its place: CNC metal faceplates, and every driver individually measured and paired before hand-assembly and acoustic channel matching. It ships with a two-core silver-plated cable — chosen for conductivity and to preserve high-frequency detail — and you can pick either a 3.5mm or USB-C cable option. Passive noise cancellation keeps the outside world at bay.
Who should buy it: audiophiles, gamers, and anyone doing music production or stage work who wants an accurate IEM and has a source to match. Who should skip it: anyone who needs to take calls. The "Without MIC" version genuinely has no microphone and no remote controls, so if communication matters, this is the wrong pick.
• Best for calls and voice chat → ASKUBSKU 3.5mm. It has a built-in mic, in-line answer/hang-up and a mute function; the Belle "Without MIC" has none of these.
• Best for pure sound quality and detail → Linsoul Kiwi Ears Belle. The 10mm DLC driver, sub-0.1% THD spec and individually paired drivers point to a more resolving listen.
• Best for students, school and Chromebook or laptop use → ASKUBSKU 3.5mm. A simple 3.5mm jack, in-line controls and a semi in-ear fit built for long wear.
• Best for gaming and music production → Linsoul Kiwi Ears Belle. Kiwi Ears explicitly tunes it for precise, responsive performance in those roles.
• Best for fit flexibility out of the box → ASKUBSKU 3.5mm. Three silicone tip sizes (L/M/S) and a 45-degree angle designed to stay put.
• Best for cable and connection flexibility → Linsoul Kiwi Ears Belle. Choose 3.5mm or USB-C at purchase, with a silver-plated two-core cable included.
• Best for bass-heavy genres → Linsoul Kiwi Ears Belle. Heavy bass and warm mids, per its tuning description.
• Best for a no-fuss, one-cord solution → ASKUBSKU 3.5mm. Plug in, control everything from the cord, done.
In my opinion, these two barely compete — they solve different problems. If your day involves calls, classes, meetings and a Chromebook or laptop, I'd buy the ASKUBSKU 3.5mm, because a mic, mute and in-line controls matter more to you than driver specs. If you listen seriously, game competitively or make music, I'd buy the Linsoul Kiwi Ears Belle, because the 10mm DLC driver, measured driver pairing and swappable silver-plated cable are built for exactly that. Pick based on whether you need to talk or need to listen — and check the current price on Amazon before you commit.
No — at least not the "Without MIC" version. It has no microphone and no remote, so it's a listening and monitoring IEM. If calls matter, pick the ASKUBSKU 3.5mm instead.
No. It's a wired 3.5mm earbud designed to plug straight into phones, laptops, tablets and handhelds. The Belle, at 32 ohm and 103 dB sensitivity, is also easy to drive, but it's aimed at users with a proper source.
By design intent, the Belle. Its 10mm DLC driver, under 0.1% THD at 1kHz and individually measured, channel-matched drivers are aimed at accurate, detailed sound. The ASKUBSKU is a HiFi stereo earbud tuned for everyday listening, not reference accuracy.
Yes, both work, but they suit different gamers. The Belle is explicitly built for precise, responsive gaming performance. The ASKUBSKU is the better pick if you also need in-game voice chat, since it has a built-in mic and mute.
The Belle lists a 1-year warranty and ships with its cable. The ASKUBSKU includes three silicone eartip sizes (L/M/S) plus a protective case, but no advertised warranty term in its data.
