If you want a large set of simple wired earbuds for school devices and sports workout use, choose JustJamz Bulk Earbuds 100; if you need reusable, adjustable on-ear headphones in mixed colors, choose MUMSTHT Classroom Headphones Bulk. JustJamz is the more straightforward fit for sharing lots of listening options across a group. MUMSTHT is the more practical choice when a headband and cushioned ear cups matter.
• JustJamz Bulk Earbuds 100: Its main strength is a 100-piece set of lightweight, wired in-ear earbuds with a standard 3.5 mm plug. The trade-off is an in-ear design and a 1-meter cable.
• MUMSTHT Classroom Headphones Bulk: Its main strength is an adjustable, foldable on-ear design with soft cushions and mixed colors. The trade-off is that the listed set contains 25 headphones, not 100, and the headphones are wired.
• Choose JustJamz for classrooms, libraries, or events where a large number of basic wired earbuds is useful.
• Choose MUMSTHT when children or adults would rather wear a headband-style pair that can be adjusted and stacked for storage.
• Neither product is wireless, and both use a 3.5 mm audio plug.
JustJamz is a bulk set of 100 wired earbuds for shared-use settings. Each pair has a 3.5 mm jack, so it can connect to compatible Chromebooks, laptops, tablets, and MP3 players. That makes this a simple option for schools, libraries, or testing rooms with a range of devices that still have a standard headphone jack. The earbuds use soft silicone tips, a lightweight plastic construction, and a 1-meter cable.
That combination makes sense when the priority is having many basic listening options available without handing out headband headphones. The in-ear shape takes up less room than a set of on-ear pairs, and the stated 1-meter cable is a clear, practical measurement for a desk or individual device. The product also lists a one-year warranty. Its audio details include a 10-millimeter dynamic driver, a 32-ohm impedance, and a frequency range of 20 Hz to 20,000 Hz.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
For sports workout use, the wired, lightweight earbud format may appeal to someone who prefers an in-ear style and is using a compatible device with a 3.5 mm jack. But this is not a Bluetooth option, and there is no stated water resistance. I would not choose it on the assumption that it can handle sweat or outdoor conditions. Skip it if you specifically want an adjustable headband, soft over-ear cushions, or a wireless connection.
MUMSTHT Classroom Headphones Bulk: Who It's For
MUMSTHT takes the opposite approach: these are wired on-ear headphones with an adjustable headband, soft ear cushions, and swivel cups. They are described as lightweight and foldable, with a design that can be stacked for storage. The mixed-color assortment can help distinguish one pair from another in a classroom or shared space. The set is listed as containing 25 headphones, and each is individually packaged.
The cable is 120 centimeters long, and the connector is a 3.5 mm L-shaped plug. The listing names compatibility with devices such as Chromebooks, laptops, computers, tablets, and phones that have a compatible jack. A longer cable than the JustJamz set gives more slack between the wearer and a device, though both products remain wired. MUMSTHT also lists a one-year warranty and describes the cable as tangle-free.
The headband and cushions make this the more natural fit for a child or adult who does not want an earbud tip sitting inside the ear. The adjustable design is intended to fit both children and adults, while the swivel cups and foldable construction support more compact storage. The trade-offs are the larger on-ear form and the smaller 25-piece set. These headphones are not water-resistant, so I would not pick them specifically for sweaty exercise. They are also not Bluetooth, despite being suitable for listening and focus at a compatible device.
• Best for supplying a large group → JustJamz Bulk Earbuds 100. The set contains 100 earbuds, compared with 25 headphones in the MUMSTHT set.
• Best for an adjustable headband → MUMSTHT Classroom Headphones Bulk. Its headband is adjustable, and its on-ear cushions offer a different fit from an earbud.
• Best for a compact in-ear design → JustJamz. Its soft silicone tips and lightweight construction suit buyers who prefer earbuds over headband headphones.
• Best for mixed-color organization → MUMSTHT. The set is listed in 10 colors, which can make pairs easier to identify in a shared classroom or activity room.
• Best for cable reach → MUMSTHT, based on the listed lengths. Its cable measures 120 centimeters; JustJamz lists a 1-meter cable.
• Best for foldable, stackable storage → MUMSTHT. Its swivel cups and foldable design are suited to putting pairs away between uses.
• Best for a straightforward 3.5 mm earbud option → JustJamz. It connects by a standard wired jack and is described for Chromebooks, laptops, tablets, and MP3 players.
• Best for a larger classroom set with a one-year warranty → JustJamz. It lists 100 earbuds and a one-year warranty. MUMSTHT also lists a one-year warranty, but its set contains 25 pairs.
A shopper searching for the best USB-C charging on-ear headphones for nurses should note that neither product is USB-C or rechargeable: both are wired and use a 3.5 mm plug. A device without that jack may require a suitable adapter, which is not included in the listed product details. Likewise, neither is a Bluetooth headset for focus. Both can provide wired listening, but neither offers Bluetooth connectivity.
For kids headphones for kids, the more important distinction is the fit. MUMSTHT offers an adjustable headband and soft ear cushions; JustJamz offers soft silicone ear tips in an in-ear style. Some children strongly prefer one form over the other, so I would choose based on how the intended wearer likes headphones to sit, rather than assuming one design suits every child.
I would choose JustJamz Bulk Earbuds 100 for a classroom, library, or group setting where the main need is a large supply of simple wired listening options. Its 100-piece set and familiar 3.5 mm connection are straightforward advantages.
For sports workout use, I would choose JustJamz only if I wanted a wired in-ear style and was using a compatible device; neither product is listed as water-resistant. If comfortable on-ear headphones, mixed colors, and foldable storage matter more, I would choose MUMSTHT instead.
JustJamz includes 100 earbuds, so it is the more suitable choice when the goal is to provide basic wired listening options to a large group. MUMSTHT includes 25 on-ear headphones and may suit a smaller group that prefers headbands and cushioned ear cups.
No. Both products are wired and use a 3.5 mm audio jack. Neither is listed as Bluetooth-enabled, so check that the listening device has a compatible headphone connection.
That depends on whether a child prefers earbuds or on-ear headphones. JustJamz has soft silicone in-ear tips; MUMSTHT has an adjustable headband and soft ear cushions. MUMSTHT is the clearer choice for someone who does not want an in-ear fit.
