If you want simple, foldable wired headphones for studying, choose noot products K22; if you need in-ear earbuds with interchangeable tips and passive noise isolation, choose YINYOO KBEAR K01. For a child using a tablet or school device, the K22’s on-ear design and five-foot cable are straightforward advantages. For someone who prefers a compact in-ear fit and wants to reduce surrounding sounds, the K01 is the more focused choice.
• noot products K22: Foldable on-ear headphones with a five-foot tangle-resistant braided cable; the trade-off is that they are wired and have no stated microphone.
• YINYOO KBEAR K01: In-ear monitors with three sizes of silicone tips and passive noise isolation; the trade-off is that they are wired and specified without a microphone.
• For younger students and shared-device use: The K22’s familiar headphone style may be easier to manage.
• For listeners who prefer an in-ear fit: The K01 offers more opportunity to adjust fit with its included small, medium, and large tips.
• Choose the K22 for a foldable on-ear headset with a long cable; choose the K01 for an in-ear design intended to help isolate some background sound.
The K22 is a wired, on-ear headphone designed with children in mind. It connects through a 3.5 mm jack, folds for packing, and uses a five-foot nylon-braided cable. That combination makes sense for study sessions at a desk, tablet time, or listening during a trip when the connected device has a headphone jack. The longer cable can provide more room to settle in without keeping the device right beside the listener.
Its appeal is practical rather than complicated. The on-ear shape avoids the need to insert an earpiece into the ear canal, and the foldable construction is useful when the headphones need to go into a bag between schoolwork and travel. The listed 20 Hz to 20,000 Hz frequency range and dynamic driver describe the audio configuration, but they do not by themselves establish how the headphones will sound to an individual listener. The K22 also includes volume control, and the product information lists a 24-month warranty.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
I’d consider the K22 for a younger student who wants familiar headphones for lessons, videos, or music. It may also suit families looking for a straightforward wired option for a tablet or other 3.5 mm device. Skip it if you specifically want earbuds that sit in the ear, or if your study setup requires a microphone: the product details do not list one. The K22 is wired, so it is not a fit for someone seeking a wireless listening setup.
YINYOO KBEAR K01: Who It's For
The K01 takes a different approach: it is an in-ear monitor with a 3.5 mm wired connection and a wraparound fit. Its included silicone tips come in small, medium, and large sizes, giving the wearer options for finding a suitable fit. The product information describes passive noise isolation when worn correctly. That means the design can help reduce some surrounding sound through the fit itself; it does not use active noise cancellation.
For studying, that distinction matters. Someone working in a room with ordinary background activity may prefer an in-ear design that aims to block some sound, especially if on-ear headphones feel uncomfortable or intrusive. The K01 is also described as having a detachable cable, which may appeal to a buyer who values that design feature. It has a 16-ohm impedance and a dynamic driver, but those figures alone cannot guarantee a particular sound preference or level of isolation in every ear.
• Best for a child’s everyday school listening → noot products K22. It is an on-ear design identified for children, with a foldable frame and a five-foot cable.
• Best for an in-ear fit → YINYOO KBEAR K01. The K01 includes three silicone tip sizes and wraps around the outside of the ear before sitting just inside it.
• Best for a longer cable reach → noot products K22. Its five-foot braided cable is specifically listed; the K01’s cable length is not provided.
• Best for passive reduction of surrounding sound → YINYOO KBEAR K01. Its product information describes passive noise isolation when the earbuds are worn correctly. That is not active noise cancellation.
• Best for packing into a bag → noot products K22. Its foldable design gives it a clear portability advantage in the listed features.
• Best for someone who wants a detachable cable → YINYOO KBEAR K01. A detachable cable is named in the product description, though no cable length is specified.
• Best for studying with a 3.5 mm device → either, depending on fit. Both are wired and use a 3.5 mm jack. Choose the on-ear K22 or the in-ear K01 based on which style suits the listener.
• Best for a listed warranty period → noot products K22. Its product details specify 24 months, while the K01 lists a one-year warranty.
The phrase “crystal clear calls earbuds for studying” may sound like a useful category, but neither product is specified with a microphone. The K01 is explicitly listed without one, and a microphone is not stated for the K22. If calls are part of the study routine, that missing feature deserves attention before choosing either model.
Neither product is a match for someone specifically seeking long battery life open ear headphones for studying. Both connect by wire, so there is no battery-life figure to compare, and neither uses an open-ear design. That is not a weakness if wired listening and the stated fit are what you want; it is simply a different category from those search terms.
My Verdict
In my opinion, I would choose the noot products K22 for a child’s everyday study setup because its foldable on-ear design, five-foot braided cable, and listed 24-month warranty make a clear, practical package.
I’d pick the YINYOO KBEAR K01 instead if I personally preferred an in-ear fit and wanted the option of passive noise isolation.
For studying, the deciding factor is not a claimed sound advantage; it is whether the listener is more comfortable with on-ear headphones or silicone-tip earbuds.
My overall pick is the K22 for a young student who needs simple wired headphones for schoolwork and travel.
For a child who prefers on-ear headphones and needs a longer cable, the K22 is the more suitable match. For someone who prefers earbuds and wants passive noise isolation, the K01 fits that need better.
Do the K22 or K01 have a microphone for calls?
The K01 is described as using passive noise isolation from its in-ear fit; it does not have active noise cancellation. The K22 lists sound isolation as a control detail, but the product information does not describe an active cancellation system.
Neither product is described as battery-powered. Both use a wired 3.5 mm connection, and no battery-life figure is listed for either one.
