If you want a colorful 20-pack of over-ear wired headphones for work, choose CN-Outlet Classroom Headphones Bulk; if you need a 25-pack of on-ear wired headphones for work, choose GDBOMA Kids Headphones Bulk. I’d make the decision based mainly on pack size and ear placement: both use a 3.5 mm connection, a four-foot cable, and a lightweight design intended for children and shared settings.
• CN-Outlet Classroom Headphones Bulk: Its strengths are the 20 individually packaged headphones, over-ear design, and four mixed colors; its trade-off is a smaller pack than GDBOMA’s.
• GDBOMA Kids Headphones Bulk: Its strengths are the 25-piece pack and on-ear design; its trade-off is that the supplied details do not specify color choices or a volume control.
• For shared devices: Both have a wired 3.5 mm plug and a 120 cm cable, a straightforward fit for compatible tablets, laptops, and classroom equipment.
• For portability: Both are listed at 1.5 ounces per headphone and use flexible plastic brackets, making them lightweight options to distribute and store.
• Choose CN-Outlet if you want over-ear headphones, individually sealed pairs, or four specified colors; choose GDBOMA if you need more pairs in one pack.
CN-Outlet is the more clearly specified choice for a classroom that wants a set of headphones with some visual variety. The 20-pack comes in baby blue, orange, dark blue, and black, and each headphone is individually packaged. That makes it easier to hand out separate pairs or keep spares organized without distributing one large, shared bundle.
The over-ear placement and 1.5-ounce weight are relevant for younger listeners and longer stretches at a desk. The product is described for children age three and up, and its bracket is made of flexible plastic that can bend. It has a wired connection, a 120 cm cable, and a 3.5 mm plug, so it fits devices such as Chromebooks, laptops, PCs, and compatible tablets. The sheet also lists a volume control and a one-year warranty.
For a school, library, or computer lab, I see the appeal in a simple wired set that does not need to be charged or paired. The trade-off is the pack size: it includes 20 headphones, five fewer than GDBOMA’s set. Its stated 32-ohm impedance and 20 Hz–20 kHz frequency range provide audio specifications, but they do not by themselves tell me how a particular student will perceive sound quality or comfort.

Who should skip it: Skip CN-Outlet if your priority is getting 25 pairs in one pack, or if you specifically want on-ear headphones.
GDBOMA’s defining advantage is quantity: the pack contains 25 wired headphones. For a classroom, testing area, or other shared-device setting that needs to equip more listeners at once, that extra set of pairs may matter more than a choice of colors or a particular ear placement. The product is described for children, teens, and adults, so its stated age range is broader than CN-Outlet’s.
These are on-ear headphones, weigh 1.5 ounces each, and use a flexible plastic bracket. They have a four-foot, or 120 cm, cable and a 3.5 mm L-shaped plug. That connector shape and length may be useful when matching the headphones to compatible devices, including Chromebooks, laptops, PCs, iPhones, iPads, and Android tablets. As with any wired set, the device needs a compatible headphone jack or connection.
The trade-off is that the supplied specifications leave some practical questions unanswered. They do not list color options, a volume control, or an audio frequency range. GDBOMA does list a one-year warranty, but the product information specifies no noise-control feature. Its on-ear design also differs from CN-Outlet’s over-ear placement, so buyers should choose based on the style they want rather than assume the two will feel identical.
Who should skip it: Skip GDBOMA if over-ear placement, individually packaged pairs, or specified mixed colors are important to your setup.

• Need a 120 cm wired connection → Either. Both products list a four-foot cable and a 3.5 mm plug.

The phrase “over ear headphones for work” may bring up many kinds of equipment, but these two products are bulk wired sets designed around children and shared environments. CN-Outlet is the one to consider if over-ear placement is the deciding factor. Neither product is wireless, so neither is a fit for someone who wants to move around without a cable.
Likewise, searches for the “best sports earbuds for work” or “best wireless earbuds for work” point toward a different kind of product. These are wired headphones, not earbuds. Their strengths are classroom-style distribution, a standard 3.5 mm connection, and light construction—not wireless use or sports-focused features.
Count the listeners first. If you need to outfit 25 people at once, GDBOMA’s pack count is the clear match. If your usual group is closer to 20, or you want to keep a smaller batch together, CN-Outlet may be a better fit. The difference is five pairs, so it is worth matching the pack to the number of devices and listeners you expect to serve.
Check the device connection. Both products use a 3.5 mm plug and are wired. That is useful for compatible equipment, but it means the headphone connection must match the device. The product details name Chromebooks, laptops, PCs, and tablets among compatible devices. GDBOMA specifies an L-shaped plug; CN-Outlet describes a bend plug.
Think about ear placement. CN-Outlet is listed as over-ear, while GDBOMA is on-ear. That is a concrete design difference, but the specifications do not establish which style will feel more comfortable to every wearer. If the headphones will be used for extended lessons or testing sessions, consider which placement better suits the listeners you are buying for.
Consider organization and controls. CN-Outlet explicitly lists four colors and individual packaging, which may help with sorting and distribution. It also lists a volume control. GDBOMA’s details do not specify either feature, so I would not assume they are present. Both list a one-year warranty, and both use a lightweight design and flexible plastic bracket.
Set sound expectations from the available details. Both are described as stereo headphones intended for learning and shared settings. CN-Outlet lists a 32-ohm impedance and a 20 Hz–20 kHz frequency range; GDBOMA lists a 32-ohm impedance but does not provide a frequency range in the supplied information. Those figures do not establish how loud the headphones will be on a particular device, or how each person will judge their sound.
If price is part of your decision, check the current price on Amazon rather than relying on an old figure. For these products, I would weigh pack count, ear placement, packaging, and the device connection alongside that information.
For work in a classroom, lab, or other shared-device setting, I would choose CN-Outlet Classroom Headphones Bulk if I needed 20 pairs and valued over-ear placement, individual packaging, and specified color options. Those details make it easier to match the set to a practical distribution routine.
I would choose GDBOMA Kids Headphones Bulk instead if the main job is supplying 25 listeners with wired headphones in one pack. In my opinion, pack count is the deciding advantage there; CN-Outlet is the more detailed fit when the design and organization features matter more.
