For swimming, the TJZXGUI Classroom Headphones Bulk are my pick among these volkanox vxh300 headphones because their lightweight, adjustable on-ear design suits kids’ listening on dry land. QearFun is the runner-up for its volume limiter and built-in microphone.
None of these three models is specified as waterproof or suitable for swimming. Treat this as a comparison for listening before or after a swim, not while in the water.
• TJZXGUI Classroom Headphones Bulk — best for shared listening setups; pick this if you want 24 wired on-ear headphones with adjustable headbands and 3.5 mm plugs.
• QearFun USB C Kids — best for children’s schoolwork and calls; pick this if a switchable volume limiter, microphone, foldable design, and USB-C connection fit your needs.
• Maxell MAX199840 — best for adult music listening and calls; pick this if you want over-ear wired headphones with an in-line microphone and sound isolation.
The TJZXGUI set is a bulk pack of 24 wired, on-ear headphones in eight colors. Each unit is individually sealed, and each uses a 3.5 mm plug with a four-foot cord. The adjustable headband is intended to provide a secure fit, while the lightweight design is described as suitable for children and adults.
The pack format makes the most sense for classrooms, libraries, or families that need several simple headsets for compatible devices. A standard 3.5 mm connection can suit laptops, tablets, and other equipment with that jack, but it will not directly fit a USB-C-only audio port without an appropriate adapter. The four-foot cable gives some room to move while seated, though it still ties the listener to the device.
These are basic headphones rather than a feature-rich personal headset. The listed specifications include stereo audio and a 32-ohm impedance, but no microphone, volume limiter, or noise control. That means they are better suited to individual listening than online conversations, and they offer no stated way to reduce surrounding noise.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
For a swimming-related search, I would consider this set only for use away from the pool or water. The product details do not identify water resistance, so I would not treat it as swimming equipment. Its strongest case is practical: a large group can use matching wired headphones without relying on wireless pairing or charging.
QearFun’s children’s headset is a wired, foldable on-ear design with a USB-C connection, a built-in microphone, and a sharing port. Its switchable volume limiter offers 85 dB and 94 dB settings. For a child using a compatible tablet or laptop, the limiter and microphone are more relevant to everyday schoolwork than decorative styling.
The mic can support online classes and calls, while the sharing port allows a second listener to connect to the same audio source through the headset. The foldable construction is handy for packing in a school bag or carry-on. The cable is described as braided and tangle-resistant, which may help with routine handling, although no cable length is listed.
QearFun is the clearest choice here for families who want kid-focused listening features. The USB-C plug is useful only when the device has a compatible USB-C audio connection; the product title also mentions a 3.5 mm sharing port, but that should not be confused with the main USB-C connection. The listed design includes memory-foam earcups and an adjustable, reinforced headband. The maker describes it for children ages three and up.
It is not a noise-cancelling kids headset for swimming. Its sound isolation is listed, but that is not active noise cancellation, and no water protection is specified. I would choose it for supervised listening on dry land, not for wearing in a pool. Its trade-off is that its child-oriented controls and connection may be a better fit for some school devices than for other audio sources.
Maxell MAX199840
This is the most adult-oriented option in the group. The over-ear fit may appeal to someone who prefers headphones that surround the ears, and the microphone gives it a role in calls as well as music and other audio. A standard 3.5 mm plug works with devices that have a matching headphone jack. The data do not list a USB-C connection, wireless playback, or a cable length.
There is a notable limitation in the available information: it does not give a volume limiter or child-specific fit details. The product is described for adults, so I would not pick it as my first option for young children. Nor would I interpret sound isolation as waterproofing or noise cancellation; neither water resistance nor active noise cancelling is specified.
For someone searching for sweat resistant sleep headphones for swimming, this is not a match based on the listed features. It is a wired headphone, not a sleep-oriented or swimming-specific product. Its real appeal is simpler: an over-ear design and in-line mic for ordinary listening and calls when a 3.5 mm connection is available.
I compared the published connection, fit, microphone, volume-control, and design details for these three models.
The ordering is my independent editorial opinion based on those specifications and likely everyday uses. No brand paid for placement.
FAQ
QearFun is the most clearly equipped for that job: it has a built-in microphone, a switchable 85 dB/94 dB volume limiter, and a foldable design. Check that the child’s device supports its USB-C audio connection.
TJZXGUI comes as a 24-pack, with individually sealed wired headphones, adjustable headbands, and 3.5 mm plugs. It is a practical fit when multiple listeners need simple headphones and the devices have compatible jacks.
All three are described as wired. QearFun lists sound isolation, and Maxell also lists sound isolation; neither listing specifies active noise cancellation. None is presented as a wireless or swimming headset.
For swimming, my recommendation is still the TJZXGUI set only for listening on dry land before or after time in the water: its 24-pack and adjustable wired design make the most sense for shared, everyday use. If a child needs a microphone and volume-limiting options for school instead, I’d choose QearFun.
