These two products get compared a lot, but they are not really rivals. The JNSA 3 is a pack of replacement triple-flange silicone eartips. The Mjaie Noise Isolating Earbuds is a full pair of wired earphones. One fixes the earbuds you have. The other replaces them. Here is how to decide which one actually solves your problem.
• JNSA 3 — biggest strength: triple-flange silicone tips that add real passive isolation and grip, sold in six pairs across three sizes, so you can dial in fit on earbuds you already like.
• JNSA 3 — biggest trade-off: it is not a headphone. If you do not already own compatible in-ear buds with a 4mm–5mm inner hole, there is nothing here to listen to.
• Mjaie Noise Isolating Earbuds — biggest strength: a complete, ready-to-use corded earphone with a soft silicone fit, sweatproof build and a 1.2 m cable, aimed at sports, travel and noisy workplaces.
• Mjaie Noise Isolating Earbuds — biggest trade-off: it is a single fixed pair in one color and one size, with a modest 100 dB sensitivity spec and no size options listed.
• Buy JNSA 3 if you want to rescue or upgrade existing earbuds and care about isolation and fit above everything.
• Buy Mjaie Noise Isolating Earbuds if you want one complete, cheap set of wired earphones for the gym, the commute or the library.
The JNSA 3 is a tuning and fit accessory, not a listening device. It is a six-pair set of triple-flange silicone eartips in small, medium and large — two pairs of each — made to fit in-ear earphones whose nozzle has an inner hole between 4mm and 5mm. That range covers a large slice of the wired and budget wireless market, and the brand lists compatibility with BeatsX, Sony XBA/MDR/DR series, Anker SoundBuds Slim+ and Curve, JBL T110BT, Phaiser BHS-750 and BHS-790, Panasonic, AKG and several others.
What the third flange does is the whole point. A standard single-flange tip seals at one point. A triple-flange tip seals at three, which stacks up passive noise isolation, and the extra flanges also add grip so the earphone stays put when you move. The silicone is soft, water-washable and replaceable, and the whole set weighs about 8.5 grams, so it disappears in a pocket or a cable pouch. If your current earbuds sound thin, leak bass or fall out on runs, that is usually a tip problem — and this is a tip fix.
Who should buy it: anyone with compatible 4mm–5mm nozzle earphones who wants more isolation on a plane, train or open-plan office, or who simply keeps losing and wearing out tips and wants spares in three sizes. Who should skip it: anyone who does not own in-ear earphones with that nozzle diameter, anyone who wants a finished product with a cable and a plug, and anyone who dislikes deep-insertion tips — triple flanges sit further into the canal than a standard dome, and some ears never get used to that.
The Mjaie Noise Isolating Earbuds is the other kind of purchase entirely: a finished pair of corded earphones. You get the earbuds, a roughly 1.2 m cable, soft silicone tips and a sweatproof build, in either yellow or blue. There is a 90-day manufacturer warranty from the date of purchase.
The design brief is clear from the description. Mjaie positions these for people who want to focus on work or study, for noisy environments, and for sports and travel. It lists offices, libraries, gyms and travel as the intended settings, and the isolation comes from the in-ear seal plus the silicone tips rather than from any active electronics. Sensitivity is listed at 100 dB, and the housing component is ABS. That is a simple, conventional wired design — the kind you plug into a phone with an adapter, a laptop, a tablet or a cheap MP3 player and forget about.
Who should buy it: someone who needs one complete, low-commitment set of wired earphones for the gym, the treadmill, a noisy commute or a shared study space, and who wants sweat resistance as part of the deal. The fixed cable also means no charging and no pairing, which matters to a lot of people in exactly those situations. Who should skip it: anyone who wants multiple tip sizes or a customizable fit, anyone who prefers wireless, and anyone who wants to choose their color beyond yellow or blue — the sheet lists blue as the primary color, with yellow also offered.
• Best for upgrading earbuds you already own → JNSA 3. Six pairs, three sizes, and a triple-flange seal that raises isolation on compatible 4mm–5mm nozzle earphones.
• Best for a complete, ready-to-use product → Mjaie Noise Isolating Earbuds. Cable, plug and tips included; nothing else to buy.
• Best for fit customization → JNSA 3. Small, medium and large, two pairs each, so you can fit each ear separately.
• Best for sports and sweating → Mjaie Noise Isolating Earbuds. It is explicitly described as sweatproof and aimed at sports.
• Best for travel and noisy commutes → Either, honestly — but JNSA 3 if you already like your current earphones, Mjaie if you do not.
• Best for focus work in offices and libraries → Mjaie Noise Isolating Earbuds, since the product is positioned for exactly those settings and needs no extra hardware.
• Best for people who lose or wear out tips → JNSA 3. It is a consumable pack, and spares are the point.
• Best for no charging, no pairing, no fuss → Mjaie Noise Isolating Earbuds. It is a wired earphone, full stop.
In my opinion, the honest answer is that these solve different problems, so I would pick based on which problem I actually have. If I already owned a pair of in-ear earphones I liked and just wanted better isolation, a firmer fit and a stack of spare tips in three sizes, I would buy the JNSA 3 — it is the more versatile purchase per unit of usefulness, because it improves gear you already have. If I had no working earphones at all, or I needed something sweatproof for the gym and a wired setup I never have to charge, I would buy the Mjaie Noise Isolating Earbuds instead. One is a fix. One is a replacement. Buy the one that matches your situation.
No. It is a set of six pairs of triple-flange silicone eartips in small, medium and large. It replaces the tips on in-ear earphones that have a 4mm–5mm inner hole; it does not include drivers, a cable or a plug.
Only if the nozzle inner diameter falls between 4mm and 5mm. The brand lists compatibility with BeatsX, Sony XBA/MDR/DR, Anker SoundBuds Slim+ and Curve, JBL T110BT, Phaiser, Panasonic, AKG and others. If your earphones are outside that 4mm–5mm range, they will not fit.
No. They are corded earbuds with a cable of roughly 1.2 m. That means no battery and no pairing, but it also means you need a headphone jack or an adapter.
Both rely on passive isolation from a silicone seal, not active noise cancellation. The JNSA 3's triple-flange shape is designed to add isolation through three sealing points, while the Mjaie earphones are described as noise-isolating in-ear earphones for noisy environments. Which one isolates better in your ears depends on how well each seals, which is why the JNSA 3's three sizes matter.
