If you want a five-pack with a stated 4-foot cable, 3.5 mm compatibility, and swivel cups, choose MKDTNJT Kids Headphones Bulk; if you need a ten-pack for outfitting more classroom listening stations at once, choose Hengliyuan Classroom Headphones Bulk. For kids with microphone, neither product lists a built-in microphone, so I would not choose either if microphone use is essential.
• MKDTNJT’s biggest strength: five individually packaged, mixed-color on-ear headphones with a 4-foot cable, a 3.5 mm L-shaped plug, and swivel cups. Trade-off: the pack contains five, not ten.
• Hengliyuan’s biggest strength: ten individually wrapped wired headphones, with retractable headbands and swivel earcups for classroom storage. Trade-off: its supplied details do not state a cable length or mention a microphone.
• MKDTNJT suits families or smaller groups that want a five-pack with a clearly specified cable length and compatibility information.
• Hengliyuan suits classrooms and programs that need a larger batch of wired headphones and value individually wrapped units.
• Both are on-ear, wired designs with 3.5 mm plugs, adjustable headbands, and one-year warranties.
MKDTNJT makes sense when you need a small group of matching-use headphones rather than a large classroom supply. The set includes five individually packaged headphones in mixed colors. Each has an on-ear design, soft ear cushions, a lightweight adjustable build, and swivel cups. That combination is useful when children share a storage area: the cups can turn to make the headphones easier to stack, while individual packaging keeps each unit separate before use.
The cable is listed at 4 feet, or 120 cm, and ends in a 3.5 mm L-shaped plug. The product details specifically name iPhone, iPad, Chromebook, laptop, PC, and Android tablets as compatible devices. That gives a buyer a clearer sense of intended connections than a general “works with devices” claim, though the actual device still needs a 3.5 mm headphone jack or a suitable adapter. These are wired headphones, not wireless ones, so there is no Bluetooth connection to set up or charge.
For schoolwork, travel, library listening, or a small group using compatible devices, the stereo audio and sound-isolation design are relevant features. The stated frequency range is 20 Hz to 20,000 Hz, and the listed sensitivity is 92 dB. Those figures describe audio specifications; they do not establish how a particular child will perceive comfort or sound quality. The thicker wire is described as intended for regular use, and the product includes a one-year warranty.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Updated: 2026-10-22 · 7 min read · Independent comparison
Who should skip it: Skip this pack if you need ten headphones in one set or require a listed built-in microphone.
The headband is retractable to adjust for adult and child head shapes, while the earcups swivel for carrying and storage. Hengliyuan also describes soft leather ear cushions and lightweight, adjustable housing. In day-to-day terms, those details point toward a design meant to accommodate different users and to be put away between sessions. The product information does not specify the cable length, though, so buyers who need to plan around the distance between a student and a device should factor that uncertainty into their choice.
Hengliyuan describes reinforced construction around the 3.5 mm plug and claims that the reinforcement is intended to extend the headphones’ useful life. That is a design intention, not a guaranteed lifespan for every classroom situation. The listed audio details include a 32-ohm impedance and 92 dB sensitivity. A one-year warranty is also stated. The pack’s larger quantity is its clearest practical advantage, but the provided details do not list a built-in microphone or wireless connectivity.
Who should skip it: Skip Hengliyuan if you need a stated cable length or a built-in microphone specification before buying.
• Best for a larger group → Hengliyuan Classroom Headphones Bulk. Its listed pack has ten headphones, compared with five in the MKDTNJT set.
• Best for a clearly specified cable length → MKDTNJT Kids Headphones Bulk. Its cable is listed as 4 feet, or 120 cm; Hengliyuan’s supplied details do not state a length.
• Best for named device compatibility → MKDTNJT Kids Headphones Bulk. Its product details name several common device types, including Chromebooks, laptops, and tablets, provided they can use a 3.5 mm connection.
• Best for individually packaged classroom units → Either, with a quantity difference. Both are described as individually packaged or wrapped; Hengliyuan’s listed set contains ten, while MKDTNJT’s contains five.
• Best for adjustable fit across children and adults → Either. Both describe adjustable headbands. Hengliyuan specifically calls its headband retractable, while MKDTNJT highlights a lightweight adjustable design.
• Best for turning cups for storage → Either. Both products list swivel earcups or cups, making them easier to arrange and store than fixed-cup designs may be.
• Best for a stated one-year warranty → Either. Both product sheets specify a one-year warranty.
• Best for wireless listening or charging → Neither. Both are wired 3.5 mm headphones. Neither product sheet describes Bluetooth or a battery.
The keyword phrase “rotatable ear cups open ear earbuds” can be confusing in this comparison. These products are not earbuds and are not described as open-ear designs; both are on-ear headphones with swivel cups. Likewise, neither is specified as “hifi stereo open ear earbuds for video calls.” If calls are the main use, confirm that a separate microphone is available through the device or choose headphones whose product details explicitly include one.
In my opinion, I would choose MKDTNJT Kids Headphones Bulk for a smaller group because the 4-foot cable and named device compatibility make planning easier.
I would choose Hengliyuan instead if I needed ten headphones in the same set for a classroom.
For kids with microphone, I would choose neither without a separate microphone solution: neither product sheet lists a built-in mic.
Both are wired, adjustable, swivel-cup options, but the pack size and stated cable details make the practical difference.
Before choosing either set, check the connection on the device each child will use. Both products have a 3.5 mm plug and are wired. A device without a compatible headphone jack may require an adapter; the product details do not say that an adapter is included. If the headphones will be used with several types of tablets or computers, MKDTNJT’s named compatibility list may help you compare, but the port on each specific device still matters.
Think about group size and storage, too. Hengliyuan’s ten-unit set is aimed at supplying more listening positions in one go. MKDTNJT’s five-unit pack may be a better match for a household, small learning group, or a program that wants a smaller batch. Both products offer mixed colors and individually separated packaging, while both have swivel cups to help with stacking or storage.
Finally, match the product to the task. A 3.5 mm headphone connection does not by itself mean that a headset has a microphone. Neither listing specifies a built-in mic, so do not assume either is ready for voice chat, classroom responses, or video calls. If you are comparing them for “fast charging clip on earbuds for kids,” that is a different product category: these are wired on-ear headphones and do not list a battery or charging feature.
Neither product’s supplied details list a built-in microphone. If children need to speak during calls or lessons, check the device’s microphone options or select a headset that explicitly specifies a mic.
Hengliyuan’s listed set contains ten headphones. MKDTNJT’s set contains five, so Hengliyuan is the more suitable of these two if pack quantity is the deciding factor.
Both products are wired and use 3.5 mm plugs. Neither product sheet lists wireless connectivity, a battery, or a charging feature, so “fast charging” is not a relevant advantage for either one.
MKDTNJT names iPhone, iPad, Chromebook, laptop, PC, and Android tablets among compatible device types and specifies a 4-foot cable. Hengliyuan also uses a 3.5 mm plug, but its supplied details do not list cable length or a comparable device list. Check the ports on the devices you plan to use.
