How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a comfortable, magnet-clipped USB-C earbud tuned for Samsung Galaxy and iPhone owners who want a set-and-forget wired pair, choose NonoUV Samsung Earbuds; if you need the most control on the cable — volume, track skipping, and a choice of three ear-tip sizes — choose KENSUKA USB C.
• NonoUV Samsung Earbuds — biggest strength: a smart DAC chip paired with a balanced armature driver and a stated 20Hz–20,000Hz range, plus built-in magnets and an anti-tangle cord for toss-in-a-bag portability.
• NonoUV Samsung Earbuds — biggest trade-off: a single multifunction button and no noise control, so you get fewer on-cable commands than the KENSUKA.
• KENSUKA USB C — biggest strength: a full in-line remote (play/pause, skip, volume, call answer/end) and three sizes of silicone tips for a customized fit.
• KENSUKA USB C — biggest trade-off: passive noise cancellation only, a 120-ohm impedance rating that can demand more drive from weaker sources, and no magnet or anti-tangle feature mentioned.
• Who each pick is for: the NonoUV suits Samsung/iPhone USB-C users who want simple plug-and-play sound and easy storage; the KENSUKA suits people who live on their cable controls and want a tailored ear fit.
The NonoUV set is built around one idea: make a USB-C earbud that simply works when you plug it into a modern phone. It uses a smart DAC chip, and the brand's framing is that this keeps the audio clean without the buzzing or popping that cheaper analog adapters can introduce. The driver is a balanced armature type with a stated frequency range of 20Hz to 20,000Hz, which is the standard full-range span — deep bass up to crisp highs, in the brand's words. I'd treat the "lossless" language as marketing flavor, but the DAC-plus-balanced-armature combo is a legitimate design choice for clarity.
Where it earns its place is convenience. The cord has built-in magnets so the two earpieces snap together instead of dangling, and the design is described as anti-tangle. If you've ever pulled a knotted cable out of a jacket pocket on a bus, you know why that matters. There's a single multifunction button for calls and music, and a built-in microphone for hands-free talking. The enclosure is plastic, the color is black, and it ships as a one-pack with a 12-month warranty. The listed compatibility covers a wide spread of Samsung Galaxy models (S and A series, Z Flip/Fold) plus iPhone 15 through 17e and 16e — basically anything with a USB-C port.
Who should buy it: Samsung Galaxy or iPhone USB-C owners who want one cable, one button, and a tidy, tangle-resistant pair for commuting, calls, and casual listening. Who should skip it: anyone who wants to change volume or skip tracks from the cable. There's no volume control here, no track skipping, and no noise control at all — the button is multifunctional, but the spec sheet doesn't promise a full remote.
KENSUKA's pitch is control and fit. The headline feature is the in-line remote: play, pause, skip tracks, adjust volume, and answer or end calls without touching your phone. That's a real, everyday difference. On a crowded train or mid-run, being able to bump the volume or skip a track from the cable is the kind of thing you notice every single day.
The second differentiator is the fit. KENSUKA includes three sizes of soft silicone ear tips, so you can match the nozzle to your ear canal instead of accepting whatever's in the box. For people whose ears never quite agree with one-size tips, that alone can decide the purchase. The cable is listed at 4 feet (1.2m) and described as tangle-free, and the build is called durable and bend-resistant. There's an advanced digital DAC chip on board as well, with the brand claiming powerful bass, clear mids, and crisp highs, plus a mic that keeps calls free of static.
On the trade-off side: KENSUKA lists passive noise cancellation, which means it blocks sound by sealing your ear — not by active electronics. The impedance is rated at 120 ohm, which is on the higher side for earbuds; in practice that can mean they want a bit more power to reach the same loudness as lower-impedance models, so weaker sources may need the volume pushed up. The color is white, it ships as one unit, and the warranty is the standard Amazon one. It also uses a USB-C jack and is positioned for iPhone 15/16/17 Pro Max types plus Samsung and other USB-C devices.
Side-by-Side: Which Should You Choose?
• Best for cable controls → KENSUKA USB C. Volume, track skip, play/pause and call handling all live on the in-line remote; the NonoUV gives you one multifunction button.
• Best for a tailored ear fit → KENSUKA USB C. Three sizes of silicone tips versus a fixed in-ear design on the NonoUV.
• Best for tangle-free storage → NonoUV Samsung Earbuds. Built-in magnets and an anti-tangle cord make it the easier pair to pocket.
• Best for Samsung Galaxy owners → NonoUV Samsung Earbuds. Its compatibility list names Galaxy S, A and Z series models explicitly.
• Best for iPhone 15–17 users → either, with a lean to KENSUKA if you want the longer 4-foot cable and full remote; NonoUV lists iPhone 15 through 17e/16e support as well.
• Best for quieter listening without electronics → KENSUKA USB C, thanks to passive noise cancellation from the tip seal.
• Best for driver clarity claims → NonoUV Samsung Earbuds, which specifies a balanced armature driver and a 20Hz–20,000Hz range.
• Best low-hassle pick → NonoUV Samsung Earbuds if you just want to plug in and go; KENSUKA USB C if you want to fine-tune how it feels and sounds.
In my opinion, I'd buy the KENSUKA USB C for most people. The in-line remote and the three sizes of ear tips solve two problems you feel every day — changing a track without digging out your phone, and getting a seal that actually fits. The NonoUV is the cleaner, simpler pick if you value magnets and an anti-tangle cord over controls, and it names more Samsung models outright. But if I had to hand one pair to a friend, it'd be the KENSUKA, with the caveat that you should check the current price on Amazon before deciding.
Both use a USB-C jack, so both fit Galaxy devices with a USB-C port. The NonoUV lists more Galaxy models by name, while the KENSUKA offers more cable controls. Pick based on whether you want buttons or simplicity.
They list passive noise cancellation, which comes from the silicone tip sealing your ear — not active electronics. If you need true active noise cancellation, neither of these two is the right fit.
Spec sheets can't settle this. Both use a DAC chip; the NonoUV specifies a balanced armature driver and a 20Hz–20,000Hz range, while the KENSUKA emphasizes tuning for bass, mids and highs. In my opinion, the NonoUV's driver spec is the more concrete claim.
The listing describes a single multifunctional button for calls and music, so don't count on dedicated volume buttons. If cable volume control matters to you, the KENSUKA's in-line remote is the safer choice.
