If you want a 100-piece class set of colorful, soft-tip wired earbuds, choose XOSDA Bulk Earbud Headphones; if you need adjustable on-ear headphones for kids with a microphone, choose MKDTNJT Classroom Headphones Bulk. For kids with microphone, the key distinction is straightforward: XOSDA explicitly has no built-in microphone, while MKDTNJT’s supplied details do not confirm one either.
For classroom listening, XOSDA offers twice as many individually packaged pairs and a silicone-tipped in-ear design. MKDTNJT has an adjustable headband and an on-ear fit, plus a cord and plug described as reinforced for repeated use. Neither product’s supplied specifications establish a built-in mic, so I would not choose either on the assumption that students can speak through the headphones.
XOSDA Bulk Earbud Headphones vs MKDTNJT Classroom Headphones Bulk at a Glance
• MKDTNJT’s biggest strength: 25 individually wrapped, mixed-color on-ear headphones with an adjustable headband. Trade-off: the pack has fewer pairs, and its supplied details do not confirm a microphone.
• Both use a wired 3.5 mm connection, making them candidates for compatible Chromebooks, tablets, phones, and computers.
• Both have a one-year warranty description in their product information.
• Choose XOSDA for a larger supply of compact earbuds; choose MKDTNJT for an adjustable headband and on-ear format.
XOSDA is the more straightforward choice when the priority is handing out a lot of compact listening sets. The pack contains 100 pairs in eight mixed colors, with each pair individually packaged. That quantity can suit a classroom, library, or other setting that needs many sets on hand. The colors can also help distinguish pairs, though the product information does not describe a labeling system or storage case.
The in-ear design has soft silicone pads, and the headphones connect through a wired 3.5 mm jack. That plug-and-play setup is useful for compatible laptops, Chromebooks, tablets, phones, and computers, without needing wireless pairing. The listed frequency range is 20 Hz to 20 kHz, and the sensitivity is 115 dB. Those figures describe audio specifications; they do not establish how loud a particular device will play or how well the earbuds will suit every listener. The cable is described as TPE, a soft material that the product information presents as durable.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.

Who should skip it: Skip XOSDA if a built-in microphone or an adjustable over-ear headband is essential.
MKDTNJT takes a different approach: the 25-pack consists of mixed-color, individually wrapped, wired headphones with an on-ear fit. Its adjustable headband is the standout design detail for a group of students who may need to share a classroom set across different head sizes. The product information describes the set as child-friendly and lightweight, but gives no specific weight or adjustment measurements.
The 3.5 mm plug is listed for use with devices such as Chromebooks, tablets, phones, PCs, and other compatible smart devices. Its cord is described as thickened, and the plug as reinforced; the product description says the connection is designed to withstand 5,000 uses. That is a stated durability claim, not a guarantee that every cord will last through any school’s handling conditions. Audio specifications include a 20 Hz to 20 kHz range, 32-ohm impedance, and 92 dB sensitivity. MKDTNJT also lists sound isolation, but does not give a reduction figure, so I would not infer a particular level of noise blocking.
Microphone needs deserve extra care here. Although the product information mentions touch controls, it does not confirm a built-in microphone or specify what those controls operate. For remote classes where children must talk, I would verify microphone compatibility before choosing this set. The pack includes 25 pairs, so it may fit a smaller group or a setting that values the headband design over having the largest number of sets.
Who should skip it: Skip MKDTNJT if you need confirmed microphone support or 100 pairs in one pack.
• Need the larger classroom supply → XOSDA Bulk Earbud Headphones. Its 100 pairs provide four times as many sets as MKDTNJT’s 25.
• Prefer a headband instead of earbuds → MKDTNJT Classroom Headphones Bulk. It has an adjustable, on-ear design; XOSDA uses silicone-tipped in-ear earbuds.
• Want individually packaged pairs → Either. Both product descriptions specify individual packaging.
• Need a confirmed built-in microphone → Neither based on the supplied details. XOSDA explicitly says it has none; MKDTNJT’s details do not establish that it has one.
• Want a 3.5 mm wired connection → Either. Check that the intended device has a compatible jack before buying.
• Prioritize a stated cord-and-plug durability claim → MKDTNJT. Its description specifies a reinforced plug and a cord designed for 5,000 uses.
• Prefer soft silicone ear pads → XOSDA. Its product details identify silicone pads; MKDTNJT instead has an on-ear fit.
• Looking for the best true wireless earbuds for webinars → Neither. Both are wired, and neither product’s supplied details confirm microphone support.
• Searching for the best hi-fi stereo open-ear earbuds → Neither is an open-ear model. XOSDA sits in the ear, while MKDTNJT rests on the ears.
• Choosing open-ear headphones for Switch → Neither matches that design. Both use a 3.5 mm wired connection, but neither is described as open-ear.
Start with the job the headphones need to do. If students only need to listen, a missing microphone may not matter. If they need to answer questions, record audio, or speak during online lessons, don’t treat a wired plug or a touch control as proof of microphone support. XOSDA explicitly excludes a built-in mic, and MKDTNJT’s listed features leave the question unanswered.
Next, consider fit. XOSDA’s silicone-tipped earbuds are compact and may work well for listeners who prefer an in-ear shape. MKDTNJT’s adjustable headband gives a different fit option and may be easier to assign across students with varying head sizes. Neither product sheet provides enough information to promise that one style will feel comfortable for every child, so the preferred fit matters.
Think about the classroom device too. Both products use 3.5 mm connections and are wired. Confirm that the devices students will use have compatible jacks; the supplied information does not specify an adapter. Finally, weigh quantity against the design you want: XOSDA supplies 100 pairs, while MKDTNJT supplies 25 and describes a reinforced cord and plug. If you are comparing overall value, check the current price on Amazon and consider the number of pairs, packaging, fit, and required features together rather than assuming pack size alone settles it.
I would choose XOSDA for a large listening-only classroom set: it provides 100 individually packaged pairs, soft silicone pads, and a standard wired 3.5 mm connection. For kids with microphone, though, I would not assume either product fits the brief. XOSDA says it has no built-in mic, and MKDTNJT’s details do not confirm one. If I needed the adjustable on-ear format and a stated reinforced cord, I’d lean toward MKDTNJT—but only after confirming microphone needs separately.
Neither product’s supplied details confirm microphone support. XOSDA explicitly has no built-in microphone; MKDTNJT’s listed information does not specify one, so check before buying for speaking activities.
Both are wired and use a 3.5 mm jack, and both descriptions include Chromebook compatibility. Confirm the particular Chromebook has a compatible jack before relying on that connection.
Which bulk classroom set has more headphones?
No. Both are described as wired products with 3.5 mm connections. XOSDA is in-ear, and MKDTNJT is on-ear; neither is described as an open-ear model.
