If you want straightforward, lightweight wired headphones for music production, choose ELECDER i37; if you need a longer cord and a stated volume-control feature, choose noot products K22. Both are foldable, on-ear headphones with a 3.5 mm connection and a 20 Hz–20,000 Hz frequency range. The practical difference is in the details: the i37 lists its 5.6-ounce weight and 4.9-foot cord, while the K22 has a 5-foot cord and lists volume control.
For production work, neither sheet establishes studio-monitor accuracy, and neither gives enough information to judge sound quality beyond its listed audio specifications. I’d choose between them based on fit, portability, cord length, and whether the K22’s stated control matters more to you than the i37’s clearly listed weight and adjustable band.
• ELECDER i37: Its listed 5.6-ounce weight, adjustable band, and folding design make it a practical option for carrying between school, home, and travel. Its trade-off: the product information says it has no microphone, remote, or volume control.
• noot products K22: It offers a 5-foot fabric cord, folding construction, and a listed volume-control feature. Its trade-off: the provided information does not specify its weight or explain how that volume control works.
• Both: Each uses an on-ear design, a 3.5 mm jack, a dynamic driver, and a listed frequency range of 20 Hz–20,000 Hz. Neither is described as wireless.
• Choose the i37 if low listed weight, an adjustable headband, and a stated lack of extra controls suit your setup.
• Choose the K22 if you prefer its slightly longer cord and want a volume-control feature listed.
The ELECDER i37 is a wired, on-ear headphone with a 3.5 mm jack, a 4.9-foot cord, and a foldable design. Its listed weight is 5.6 ounces. For everyday use, those details point to a simple setup: plug it into a compatible device, adjust the band, and fold it away when it is time to pack. The adjustable band is described as suitable for children and many adults, which gives it more flexibility than a fixed-fit kids’ model.
For music production, I see the i37 as a basic listening option for someone working with a compatible laptop, computer, tablet, or other device that has a 3.5 mm jack. Its stated frequency range is 20 Hz–20,000 Hz, and the driver is listed as 40 millimeters. Those are useful specifications to compare, but they do not establish how accurately the headphones reproduce a mix. The sheet also lists sound isolation, though it does not describe a noise-cancelling system. I would treat this as a straightforward wired headphone rather than assume it provides studio-reference monitoring.

Who should skip it: Skip the i37 if you need a built-in microphone, a remote, or headphone volume controls; the product information explicitly says those are absent.
noot products K22: Who It's For
The noot products K22 is also a wired, foldable, on-ear headphone with a 3.5 mm jack. Its cable is listed at 5 feet, just slightly longer than the i37’s 4.9-foot cord. That small difference may matter if your device sits across a desk or if you want a little more room to shift position, but it is not a major leap in cable reach. Its fabric-covered nylon cord is described as helping resist tangles and adding durability.
The K22’s listed frequency range is 20 Hz–20,000 Hz, and it uses a dynamic driver. It also lists sound isolation and volume control. The available information does not specify a microphone, so I would not choose it on the assumption that it can handle voice calls or recording. Nor does the sheet explain whether the volume control is on the cable or earcup, or how it operates. For a buyer who wants that feature, it is worth checking the product details before relying on it in a particular setup.
Who should skip it: Skip the K22 if you need a clearly documented microphone, a stated weight for comparing lightweight options, or detailed information about its volume-control placement and operation.
• Best for a clearly stated lightweight spec → ELECDER i37. It is listed at 5.6 ounces. The K22’s information does not give a weight, so there is no fair weight comparison.
• Best for the longer listed cord → noot products K22. Its cable is 5 feet; the i37’s is 4.9 feet. The difference is small, but the K22 has the longer stated reach.
• Best if an adjustable band matters → ELECDER i37. Its product information specifically describes an adjustable band intended to fit children and many adults.
• Best if you want volume control listed → noot products K22. Its information names volume control, while the i37 explicitly has none. The K22’s control details are not provided.
• Best if you need a microphone → neither, based on the available details. The i37 explicitly lacks one; the K22’s product information does not establish that it includes one.
• Best for a foldable wired option → either. Both fold and connect through a 3.5 mm jack. Choose based on the fit and cord details that matter more to you.
• Best for assessing production sound from specifications alone → neither has a decisive advantage. Both list the same 20 Hz–20,000 Hz frequency range and a dynamic driver, but those facts do not establish comparative accuracy.
• Best for a child who also needs adult flexibility → ELECDER i37. Its adjustable band is described as accommodating children and many adults; the K22 information identifies it for children but does not describe an adjustable fit.
For music production, I would choose the ELECDER i37 if I wanted the more clearly documented fit and weight: it is listed at 5.6 ounces, has an adjustable band, and folds for carrying. I would choose the noot products K22 instead if its five-foot cord and stated volume control better match my setup. Neither product’s listed specifications prove studio accuracy, so I would treat both as basic wired listening options rather than assume either is a production reference headphone.
Before choosing, check the device you plan to use. Both headphones rely on a 3.5 mm connection, and neither is described as wireless. If your production device does not have a compatible jack, these product details do not establish another connection method.
Think about fit and listening position, too. The i37 gives a listed weight and an adjustable band; the K22 gives a slightly longer cable. Those are concrete differences, but the sheets do not provide dimensions, clamping force, or padding details, so they cannot settle how either pair will feel on a particular head over a long session.
If you are searching for the best kids headphones for music production, the “best” choice depends on the child’s device, comfort needs, and whether a microphone or volume control is important. The i37 explicitly has no microphone or volume control; the K22 lists volume control but does not specify a microphone. Neither sheet establishes that either headphone is designed for professional monitoring.
The phrase “lightweight head phones for music production” may lead you toward the i37 because its weight is stated at 5.6 ounces. But the K22’s weight is simply not provided here, so that figure does not prove the i37 is lighter than the K22. Likewise, neither is described as sports earbuds: both are wired, on-ear headphones, not earbuds. For active use, consider whether that form and a cord suit the activity rather than assuming either is built for sports.
Finally, consider what you need from controls. The i37’s lack of a microphone, remote, and volume control is clearly stated. The K22 lists volume control, but its placement and operation are not explained. If a particular control is essential for your workflow, verify that detail before deciding.
Neither has enough information here to establish accurate studio monitoring. Both list a 20 Hz–20,000 Hz frequency range and a dynamic driver, so I would choose based on fit, cord length, and controls rather than assume one sounds more precise.
Does the ELECDER i37 or K22 have a microphone?
The i37 explicitly does not have a microphone.
The K22 lists volume control. The i37’s product information says it has no volume control; the K22 details do not explain where its control is or how it works.
The i37 is listed at 5.6 ounces, and both models fold for carrying. The K22’s weight is not specified, so the information does not establish which is lighter; both use a wired 3.5 mm connection.
