noot products K22 vs YINYOO KBEAR K01 at a Glance
• noot products K22 — biggest strength: A foldable, lightweight on-ear design with a 5ft nylon braided tangle-free cable, volume control, and a 24-month hassle-free warranty. Built for kids aged 3–16, school, travel and tablets.
• noot products K22 — biggest trade-off: It's an on-ear children's headset with sound isolation, not a passive-isolating IEM. No detachable cable, no swappable ear tips, and nothing in the spec sheet points to a hi-fi tuning.
• YINYOO KBEAR K01 — biggest strength: A 10mm single dynamic driver IEM with 16 ohm impedance, detachable cable, and three sizes of silicone ear tips for passive noise isolation. Aimed at Hi-Fi enthusiasts and musicians.
• YINYOO KBEAR K01 — biggest trade-off: This version ships without a microphone, so it's not the pick if you need voice input. It's also an in-ear design, which some people simply don't get along with.
• Who each is for: K22 → parents buying for a child, or anyone who wants a simple plug-and-play on-ear set for media and school. K01 → listeners and musicians who want an affordable wired IEM with a replaceable cable.
The K22 is a children's headphone first and an audio product second, and that framing explains almost every design decision. It's an on-ear set with a teal and lime colourway, a foldable frame, and a 6.08-ounce build that's meant to sit lightly rather than clamp down. The 5ft nylon braided cable is the standout detail here — nylon braiding is exactly the kind of thing that stops a cable from turning into a knot in a backpack, and 5ft gives a child enough slack to move around a tablet or a Kindle without yanking the plug out of the jack.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.

On the audio side, the spec sheet lists a 32 ohm impedance, a 10mm-class dynamic driver pairing implied by the dynamic driver type, and a 20Hz–20,000Hz frequency range. That's a standard full-range consumer tuning. Nothing here suggests it's been voiced for critical listening, and it doesn't need to be — it's voiced for music, movies, games and schoolwork, which is exactly how noot products positions it.
Buy the K22 if: you're buying for a child aged 3–16, you want a wired set that works with an iPad, Kindle, school laptop or in-flight entertainment, and you value the foldable frame and the 24-month hassle-free warranty with easy-to-reach customer service.
Skip the K22 if: you're an adult chasing sound quality for production work, you want a detachable cable, or you need a microphone for calls. The sheet doesn't list one, so don't assume it's there.
The K01 is a different animal entirely. YINYOO builds this as an in-ear monitor — an IEM — and the spec sheet reads like a budget audiophile product rather than a consumer accessory. The headline number is the 10mm single dynamic driver, paired with a low 16 ohm impedance. Low impedance matters for a practical reason: it means the K01 is easy to drive, so a phone, a laptop headphone jack or a cheap portable DAC doesn't have to work hard to get usable volume out of it. You don't need a dedicated amp to make these sing.
The second headline is the detachable cable. That's a genuinely useful feature at this end of the market, because cables are the first thing to fail on any wired earphone. If the cable dies, you replace the cable, not the earphones. The K01 also ships with small, medium and large silicone ear tips, which matters more than people expect — the seal you get from a correctly sized tip is what determines both comfort and bass response.
And that's the third point: passive noise isolation. The K01 wraps around the outside of your ear and sits just inside the canal, and when you get the fit right, the silicone tip physically blocks background sound. No active noise cancellation circuitry, no battery, no charging. Just a seal. The polycarbonate housing in clear black keeps the weight down, and YINYOO backs it with a 1-year warranty and a stated policy of dealing with reported issues via replacement.
Buy the K01 if: you want an affordable wired IEM for music, gaming or video calling, you like the idea of a replaceable cable, and you want passive isolation without batteries. This is the more credible pick of the two for bone conduction headphones for music production shoppers who've realised they actually want wired isolation instead — bone conduction deliberately lets sound in, and that's the opposite of what a producer wants when tracking or mixing.
Side-by-Side: Which Should You Choose?
• Best for music production → YINYOO KBEAR K01. A 10mm dynamic driver, 16 ohm impedance, detachable cable and passive isolation is a real monitoring setup. The K22 is a children's headset.
• Best for kids, school and travel → noot products K22. Foldable, 6.08 ounces, 5ft tangle-free nylon cable, volume control, ages 3–16.
• Best if you want a replaceable cable → YINYOO KBEAR K01. Detachable cable means a failed cable isn't a dead product.
• Best if you need a microphone → neither, as specified. The K01 variant is the without-mic model, and the K22 sheet doesn't list a mic. If a mic is non-negotiable, look at the version of the K01 that includes one if available.
• Best for long listening sessions → noot products K22. On-ear, lightweight, no ear canal pressure. The K01's tips will feel more invasive to some people.
• Best for noisy environments → YINYOO KBEAR K01. Passive noise isolation from a proper tip seal beats on-ear sound isolation.
• Best for plugging into a phone or laptop without extra gear → YINYOO KBEAR K01. 16 ohm impedance is easy to drive from almost anything with a 3.5mm jack.
• Best warranty coverage → noot products K22. 24 months, versus 1 year on the K01.
If I were buying for myself and the goal was music production, I'd buy the YINYOO KBEAR K01. In my opinion, the 10mm dynamic driver, the 16 ohm impedance and the detachable cable are the three features that actually matter for that job, and passive isolation from a good tip seal is far more useful in a studio or a bedroom setup than on-ear sound isolation. The K22 is a genuinely sensible product — but it's a kids' headphone, and buying it for production work would be buying the wrong tool on purpose. Buy the K22 for a child; buy the K01 for yourself.
For a wired budget IEM, yes. The 10mm dynamic driver and 16 ohm impedance make it easy to drive from a laptop or interface, the detachable cable means you can replace it if it fails, and the silicone tips give you passive isolation from room noise.
The spec sheet doesn't list one, so don't count on it for calls. It does list a volume control with a touch control method, and it's positioned for music, movies, games and schoolwork rather than voice chat.
They're solving different problems, so value depends on the job. For a child's everyday headphone with a 24-month warranty, the K22 makes sense. For an entry-level IEM with a replaceable cable and a 1-year warranty, the K01 makes sense. Check the current price on Amazon before deciding — that's the only way to judge value fairly.
Gaming, yes — YINYOO markets it for gaming and the passive isolation helps. For calls, remember this is the without-mic version, so you'd need a separate mic or a different variant.
