If you want a single foldable headphone for kids wireless-style listening without Bluetooth, choose ELECDER i45; if you need five wired classroom headphones in one package, choose MKDTNJT Kids Headphones Bulk. Neither is wireless: both use a 3.5 mm cable. The real choice is one portable pair or a set for a group.
ELECDER i45 vs MKDTNJT Kids Headphones Bulk at a Glance
• ELECDER i45: One foldable on-ear pair, with a 1.5-meter cable and 40 mm drivers; the trade-off is that it is wired and has no headphone volume buttons.
• MKDTNJT Kids Headphones Bulk: Five individually packaged pairs with 3.5 mm plugs; the trade-off is that the set is wired and does not provide a stated folding design.
• Comfort and storage: ELECDER has padded ear cushions and a folding frame; MKDTNJT offers soft cushions, adjustable sizing, and swivel cups for stacking.
• Cable length: ELECDER’s cord is 1.5 meters; MKDTNJT’s is 120 centimeters.
• Who each suits: ELECDER is for someone choosing one portable pair for a child or teen; MKDTNJT is for a household or organization that needs several pairs.
The ELECDER i45 is a single wired, on-ear headphone designed to fold for easier carrying. Its 40 mm drivers are described as providing moderate bass and clear midrange, while sound isolation can reduce some background noise. Those details make it a straightforward option for everyday listening on a compatible device, including a Chromebook or computer with a 3.5 mm jack.
Its adjustable headband and padded ear cushions are intended for children over 8 and teens, while the adjustable fit may also suit adults. I’d consider it for a student who needs one pair to move between schoolwork, a tablet, and travel. The foldable frame is useful when bag space matters, and the 1.5-meter cable gives some room to sit away from the device.

Skip it if you need wireless listening, a bundle for multiple students, or buttons for changing volume on the headphones. The i45 has no volume-control buttons, so adjustments must be made on the connected device. It also requires a 3.5 mm connection; newer devices without that jack may need an adapter, which is not included for certain iPhone and iPad models.
The main draw here is quantity: the package contains five wired, individually packaged on-ear headphones in mixed colors. That makes the MKDTNJT set more naturally suited to classrooms, libraries, shared work areas, or families with several children than to someone shopping for just one personal pair. Each headphone has a 3.5 mm plug for compatible devices.
The design includes adjustable sizing, soft ear cushions, and swivel cups that help with stacking and storage. The maker also describes the construction as bendable, with a thicker wire intended for repeated daily use. Those features point toward shared environments where headphones need to be handed out, collected, and stored between sessions. The cable is 120 centimeters long, shorter than the ELECDER’s 1.5-meter cord.
The key limitation is that this is still a wired set, not a wireless solution. The product information does not specify a folding frame or individual volume controls, so I wouldn’t choose it on the assumption that either feature is included. It makes more sense when you need multiple basic headphones with 3.5 mm connections than when you want one personal pair with a compact folding design.
• Need one pair for one child or teen → ELECDER i45. It is sold as a single headphone, while the MKDTNJT package contains five.
• Need headphones for a classroom or group → MKDTNJT Kids Headphones Bulk. Five individually packaged pairs give you more units to distribute across students or shared spaces.
• Want foldable portability → ELECDER i45. Its frame folds for easier carrying; the MKDTNJT description focuses instead on swivel cups for stacking.
• Want swivel cups for storage → MKDTNJT. Its cups swivel to make the headphones easier to stack.
• Prefer a longer cable → ELECDER i45. Its cord measures 1.5 meters, compared with 120 centimeters for the MKDTNJT.
• Need a headphone volume button → Neither is a clear fit. The ELECDER explicitly lacks volume buttons, and the MKDTNJT information does not establish that it has them.
• Need Bluetooth or cable-free listening → Neither. Both connect by 3.5 mm cable; MKDTNJT explicitly identifies its wireless technology as none.
• Looking for a hiking headphone → Neither has a stated wireless or water-resistance feature. For walking outdoors, their cables and lack of specified water protection are important limitations.
• Shopping for a studying headphone that is specifically IPX7 waterproof → Neither is specified that way. Sound isolation is mentioned for both, but no IPX7 rating is provided.
• Searching for bone conduction headphones with Dolby Atmos → Neither matches that description. Both are conventional on-ear, wired headphones, and neither sheet identifies bone conduction or Dolby Atmos.
The last three searches highlight why it is worth checking the actual feature list rather than relying on a broad use-case phrase. “For studying” does not establish waterproofing, and neither of these products is described as a hiking-ready wireless model. Their documented strengths are simpler: wired listening, on-ear fit, and compatibility with devices that have a 3.5 mm jack.
Compatibility is worth checking before choosing either. A 3.5 mm plug works only when the device has that connection or an appropriate adapter. The ELECDER listing specifically notes that some newer Apple devices need an adapter, and it is not included for those models. MKDTNJT also uses a 3.5 mm L-shaped plug, so the same basic port check applies.
There’s also a difference in how each product solves the storage problem. ELECDER folds, which is convenient if one child carries a pair in a backpack. MKDTNJT’s swivel cups are aimed at stacking several pairs together. If you are managing a shared cart or storage area, that may be more useful than a single foldable frame; for an individual commuter or student, the foldable design has the more direct advantage.
Neither spec sheet establishes a volume limit, a waterproof rating, Bluetooth, or a noise-canceling system. Both mention sound isolation, but that is not the same as active noise cancellation. I would keep expectations centered on basic wired audio in reasonably quiet settings, not on specialty outdoor or immersive-audio features.
I’d choose the ELECDER i45 if I were buying one pair for a child or teen: it folds, has a longer cable, and is built around individual everyday use. For kids wireless, though, neither is the right answer because both are wired. If I needed headphones for a classroom or several children, I’d choose the five-pack MKDTNJT instead; its quantity is the clear reason to pick it.
No. Both use a 3.5 mm cable, and MKDTNJT is specifically listed as having no wireless technology. Choose a different model if Bluetooth listening is essential.
MKDTNJT is the more suitable option for a group because its package contains five individually packaged headphones. ELECDER is a single-pair choice, so it makes more sense for one student.
ELECDER’s cable is 1.5 meters long. MKDTNJT’s cable is 120 centimeters, so ELECDER provides the longer reach between the listener and the connected device.
Neither product information sheet specifies a waterproof rating such as IPX7 or active noise cancellation. Both mention sound isolation, but that should not be treated as a claim of waterproofing or noise-canceling technology.
