If you want a larger classroom supply of wired USB-C headphones, choose CNSZSLZ USB C Headphones; if you need a smaller five-headphone class set, choose XOSDA Type C Kids. For kids bluetooth use, neither is wireless: both connect by USB-C cable, so choose based on pack size and the features each actually lists.
• CNSZSLZ USB C Headphones: A 10-pack with adjustable headbands, soft ear cushions, and four-foot cables; the trade-off is that it is wired and lists no noise control.
• XOSDA Type C Kids: A five-pack with adjustable headbands, soft cushions, and listed sound isolation; the trade-off is that the cable length is not specified.
• Both are on-ear, wired USB-C headphones for compatible tablets, smartphones, and computers. Neither is a Bluetooth headset.
• CNSZSLZ suits classrooms that need more individual headsets in one pack and value a stated cable length.
• XOSDA suits buyers who need five headphones and want sound isolation identified among the features.
• These are practical classroom-style headphones, not wireless lifestyle headsets. That distinction matters more than any bass or noise-cancellation search phrase here: both products use a USB-C connection, and neither data sheet describes Bluetooth or active noise cancellation. The real choice is between a larger pack with a specified four-foot cable and a smaller pack that lists sound isolation and media control.
CNSZSLZ’s clearest advantage is its 10-headphone pack. That makes it a sensible option for a classroom, testing session, shared computer area, or family that needs several USB-C headsets ready at once. Each headphone is individually bagged, which can help keep pieces separated when distributing, collecting, or storing them. The package is described as a carton box, so the set is organized around supplying multiple users rather than a single listener.
The headphones are on-ear and wired, with a USB-C connector and a four-foot cable. That cable length is useful to know when planning where students will sit relative to a tablet or laptop. The headband adjusts, and the ear cushions are described as soft and lightweight. The listed age range includes kids, teens, and adults, which suggests a flexible fit range, though an adjustable band does not guarantee the same comfort for every head. The product lists compatibility with USB-C tablets, smartphones, and laptops; device compatibility is still worth checking before outfitting a whole group.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.

XOSDA is a five-pack of on-ear USB-C headphones, making it a more focused fit for a small group, a handful of shared devices, or a household that does not need a larger class set. The adjustable headband and soft cushion earpads are described as comfort features for extended use. The listed age range covers kids, teens, and adults, so it is not presented as a child-only fit despite the name.
Its wired USB-C connection is described as plug-and-play, with compatibility identified for modern iPads, Chromebooks, laptops, smartphones, and other listed device types. That makes the connection simple in principle: plug the USB-C connector into a compatible device rather than managing a separate wireless pairing process. The sheet also lists sound isolation and media control. Sound isolation is not the same as active noise cancellation, and no microphone is included. XOSDA lists a 20 Hz to 20 kHz frequency range and 32-ohm impedance, but those figures alone do not establish how full, clear, or bass-heavy the headphones will sound in everyday use.
A limitation for classroom planning is that the cable length is not specified, so there is less information for judging how much slack students will have at desks. The pack includes five individually wrapped headphones. Skip XOSDA if you need more than five headsets in a single pack, a microphone, Bluetooth, or a specified cable length.
• Need a larger group pack → CNSZSLZ USB C Headphones. Its 10-headphone set provides more individual units than XOSDA’s five-pack.
• Need a compact set for a small class or shared devices → XOSDA Type C Kids. Five headphones may be easier to allocate when a full classroom set is unnecessary.
• Want a stated cable length → CNSZSLZ USB C Headphones. Its cable is listed as four feet; XOSDA’s cable length is not provided.
• Want sound isolation listed in the product details → XOSDA Type C Kids. CNSZSLZ lists no noise control. Sound isolation should not be mistaken for active noise cancellation.
• Need individually packaged headphones → Either one. Both descriptions identify individual packaging, useful when handing out and collecting shared equipment.
• Need USB-C wired audio → Either one, with device compatibility checked first. Both use USB-C and are wired, so neither is the choice for Bluetooth listening.
• Shopping for extra bass kids headphones → Neither sheet establishes an extra-bass tuning. XOSDA supplies a frequency range, but that specification does not by itself prove a bass-forward sound.
• Looking for the best ANC wireless headset → Neither product fits that request. Neither lists Bluetooth or active noise cancellation.
For classroom use, pack size is a concrete difference, while much of the rest of the comparison is about how much each product tells you. CNSZSLZ gives a cable length, which helps with desk and device placement. XOSDA identifies sound isolation and media control, but leaves cable length unspecified. Neither sheet provides enough information to make a dependable claim about deep bass, maximum loudness, or how well the headphones block a busy room.
That also makes “best deep bass wireless headset for side sleepers” a poor match for this pair. Both are on-ear classroom-style wired sets, not wireless sleep headphones, and neither sheet describes a deep-bass design or a sleep-focused shape. If that is your actual use case, I would look for specifications designed for wireless listening and sleeping rather than trying to stretch these classroom models into that role.
Before choosing either pack, check the connection on the devices that will use it. Both products have USB-C connectors, but the sheets do not guarantee compatibility with every device that happens to have a USB-C port. CNSZSLZ names tablets, smartphones, and laptops; XOSDA identifies modern iPads, Chromebooks, laptops, smartphones, and related devices. For a classroom purchase, confirm the specific device model and operating setup before buying several sets.
Next, consider how the headphones will be used and stored. Both are on-ear and have adjustable headbands with soft cushions, but neither sheet gives dimensions, weight figures, or a detailed fit range. CNSZSLZ describes its design as lightweight and easy to store and carry. XOSDA gives no specific weight or folded-storage detail. If headphones will be passed between students, individual packaging is a practical feature on both; it does not, by itself, establish how durable the headbands, cables, or cushions will be over time.
Finally, match the feature claims to your expectations. XOSDA lists sound isolation, but that does not mean the headphones actively cancel noise or will make a room quiet. CNSZSLZ lists no noise control. Neither product includes a microphone according to the available information, so they are not the right picks if students need to speak during calls or online lessons. Both list a one-year warranty description, but neither sheet specifies a microphone, wireless battery, or Bluetooth connection. If you are comparing overall value, check the current price on Amazon and weigh it against the number of headsets and the features you will actually use; no price is assumed here.
My Verdict
I would choose CNSZSLZ USB C Headphones for a classroom or shared-device setup because its 10-pack is the more useful format when several students need headphones, and its four-foot cable gives a clear planning detail. For kids bluetooth use, though, I would not mistake either pick for a wireless option: both are wired USB-C sets. I’d choose XOSDA instead for a smaller group where its listed sound isolation and media control matter more than pack size.
No. Both are wired headphones with USB-C connectors. If you need Bluetooth, these two products do not meet that requirement.
CNSZSLZ provides 10 headphones, while XOSDA provides five. I’d choose CNSZSLZ for supplying a larger group in one pack, and XOSDA when five units are enough.
The product details list sound isolation, not active noise cancellation. That is a different claim, and the sheet does not identify an ANC feature.
The available details do not establish that either model has an extra-bass sound profile. XOSDA lists a frequency range, but that alone does not confirm bass emphasis; XOSDA also states that it has no microphone, and CNSZSLZ does not list one.
