• GDBOMA biggest strength: 25 pairs of on-ear headphones with a 3.5 mm L-shaped plug that fits iPhone, iPad, Chromebook, laptop, PC and Android tablets — the widest everyday device coverage for a classroom mix.
• GDBOMA biggest trade-off: No USB-C option at all, so any device without a 3.5 mm jack needs an adapter you would have to source yourself.
• ZHENWAY biggest strength: 30 pairs with a native USB-C jack, ideal for schools that have standardized on USB-C tablets, laptops and phones.
• ZHENWAY biggest trade-off: USB-C only — older laptops, desktops and many classroom PCs with a round audio jack simply won't work without an adapter.
• Pick GDBOMA if your students use a mix of iPads, Chromebooks, PCs and phones with headphone jacks, and you want a lighter, bendier pair for very young kids.
• Pick ZHENWAY if your classroom or lab has moved to USB-C devices and you want a larger pack with a longer cable and an adjustable headband.
The GDBOMA pack is a 25-count set of wired on-ear headphones aimed squarely at schools, testing rooms and shared learning spaces. Each pair weighs only 1.5 ounces, which is genuinely light for a child to wear through a lesson, and the headband is built from flexible plastic that bends at a wide angle — the kind of give that survives being pulled on and off by kids aged 3 and up. The mixed-color design is a quiet bonus in a classroom: it makes it easy to hand out and spot pairs, and it signals "these belong to the class" rather than "these belong to one student."
The 3.5 mm L-shaped plug is the part that matters most for real classrooms. An L-shaped connector sits flush against the side of a tablet or phone, which means it takes less abuse when a device is lying flat on a desk or being passed around. GDBOMA lists compatibility with iPhone, iPad, Chromebook, laptop, PC and Android tablets, so this is the safer pick when you genuinely don't know what devices your students will bring. The 4-foot cable is a reasonable working length for a desk, though not generous if you want students standing up.
Who should buy it: teachers, school IT coordinators, testing administrators and anyone equipping a mixed-device classroom who wants the broadest plug compatibility and a very light fit for younger children. Who should skip it: anyone whose devices are USB-C only, or who needs a longer cable for students who move around. If your entire fleet has moved to USB-C, GDBOMA becomes the wrong tool — you'd be buying adapters for every seat.
ZHENWAY USB-C Headphones Bulk: Who It's For
The ZHENWAY pack goes the other direction: 30 pairs, all USB-C, all black. If your school, lab or testing center has standardized on USB-C tablets, Chromebooks, laptops and smartphones, this is the plug you actually want, because there's no adapter chain to lose, break or troubleshoot mid-exam. ZHENWAY lists compatibility across classroom desktop computers, laptops, Chromebooks, tablets, smartphones and other audio devices — with the caveat that "USB-C" has to actually be the port you're plugging into.
Two specs stand out. First, the 4.5-foot cable is half a foot longer than GDBOMA's 4-foot cable, which matters in practice when a student leans back, stands at a whiteboard or shares a table. Second, the headband is adjustable and, like GDBOMA's, made from flexible plastic that bends at a wide angle and is described as tough enough to last — so it's designed to fit a range of head sizes rather than a single age band. ZHENWAY markets it for children and teenagers, and the adjustable sizing backs that up.
The audio spec is where the two diverge most: ZHENWAY lists 140 ohm impedance versus GDBOMA's 32 ohm, with no driver type specified. Higher impedance generally means a device has to work harder to reach the same loudness, so on weak outputs you may find yourself pushing the volume further. That's not automatically bad — higher impedance can behave better on stronger sources — but for a classroom full of budget tablets, the lower-impedance GDBOMA pair is the more forgiving match. ZHENWAY's own material leans on "good sound quality," "light and comfortable" and "durable and easy to carry," which is the right framing for a bulk school headphone rather than an audiophile product.
Who should buy it: schools and labs that have gone USB-C, buyers who want a larger 30-pack, and anyone who needs the extra cable length and the adjustable headband for a wider age range up through teenagers. Who should skip it: anyone still running 3.5 mm jacks on desktops, older laptops or non-USB-C tablets — this pack gives you no fallback, so mismatched hardware means a pile of unusable headphones.
• Best for mixed-device classrooms → GDBOMA Kids Headphones Bulk. The 3.5 mm L-shaped plug covers iPhone, iPad, Chromebook, laptop, PC and Android tablets.
• Best for USB-C-only schools → ZHENWAY USB-C Headphones Bulk. Native USB-C across desktops, laptops, Chromebooks, tablets and smartphones.
• Best for the youngest students → GDBOMA Kids Headphones Bulk. At 1.5 ounces per pair and rated for ages 3 and up, it's the lighter, smaller-head option.
• Best for a wider age range → ZHENWAY USB-C Headphones Bulk. The adjustable headband is aimed at children and teenagers rather than just early grades.
• Best for cable reach → ZHENWAY USB-C Headphones Bulk. 4.5 feet versus GDBOMA's 4 feet.
• Best for easy-to-drive audio → GDBOMA Kids Headphones Bulk. 32 ohm impedance is friendlier to low-power tablets and laptops than ZHENWAY's 140 ohm.
• Best for pack size → ZHENWAY USB-C Headphones Bulk. 30 pairs versus GDBOMA's 25.
• Best for standardized exams and shared-use spaces → either, depending on your ports. Both are marketed for schools, testing, labs, libraries, hospitals and gyms.
In my opinion, the deciding factor here isn't the headphones at all — it's the port on the devices your students actually use. If I were outfitting a general classroom where iPads, Chromebooks, PCs and phones all show up with a round headphone jack, I would buy GDBOMA Kids Headphones Bulk: the 3.5 mm L-shaped plug is the most universally compatible choice, the 1.5-ounce build suits younger kids, and the 32 ohm impedance plays nicely with low-power tablets. If I were equipping a USB-C-only lab, I would buy ZHENWAY USB-C Headphones Bulk without hesitating — the native USB-C jack, longer 4.5-foot cable and adjustable headband are exactly what that setup needs. Check the current price on Amazon for both before you commit, since bulk-pack value shifts over time.
No. GDBOMA uses a 3.5 mm L-shaped plug only, so a USB-C-only tablet or phone would need a separate adapter. If your devices are USB-C, the ZHENWAY pack is the direct fit.
Both are designed for classroom use and student exams. The real question is your hardware: GDBOMA for 3.5 mm jacks, ZHENWAY for USB-C ports. Match the pack to your devices and you'll avoid adapter problems during testing.
GDBOMA Kids Headphones Bulk includes 25 pairs. ZHENWAY USB-C Headphones Bulk includes 30 pairs. ZHENWAY also gives you a slightly longer 4.5-foot cable versus GDBOMA's 4 feet.
GDBOMA's 32 ohm impedance is easier for low-power devices to drive, so it tends to reach usable volume more readily. ZHENWAY's 140 ohm impedance may require higher volume settings on weaker outputs, though it can pair well with stronger audio sources.
No. GDBOMA lists no noise control, and ZHENWAY makes no active noise-cancelling claim either. Both are straightforward wired on-ear headphones rather than noise-cancelling models.
