If you want a colorful, individually packaged classroom set with adjustable headbands, choose XOSDA 50; if you need a black wired set with a wider listed frequency range, choose ZXQZYM Kids Headphones Bulk. For sleeping, neither is presented as a sleep-specific design, but the on-ear fit makes the shape worth considering alongside your actual comfort needs.
XOSDA 50 vs ZXQZYM Kids Headphones Bulk at a Glance
• ZXQZYM Kids Headphones Bulk’s biggest strength: a black wired design with a listed 20 Hz–20,000 Hz frequency range and 3.5 mm plug. Trade-off: it has no listed noise control, and its product information describes the age range as kids and teens.
• Choose XOSDA 50 for classroom distribution, color-coding, and a set intended to fit children, teens, and adults.
• Choose ZXQZYM Kids Headphones Bulk for a straightforward black set where the broader stated frequency range matters more than color choices or listed noise control.
XOSDA 50 is a wired, on-ear classroom set built around group use. The package contains 50 headphones, each individually bagged, and includes 12 colors. That combination is useful when a teacher, program coordinator, or family needs to hand out headphones while keeping pairs distinguishable. Color variety can also help organize different groups or stations without relying on labels alone.
The retractable headband is designed to adjust across children, teens, and adults. XOSDA also describes soft silicone ear cushions and a lightweight build for longer wearing sessions. Those details point toward lessons, computer lab activities, distance learning, and travel where students may wear headphones for a while. A 90-degree swivel ear cup can make the headphones easier to place or store, while the reinforced 3.5 mm plug is intended for repeated handling. The listed frequency range is 80 Hz–18,000 Hz, with 32-ohm impedance and a dynamic driver.
For sleeping, the on-ear construction may appeal to someone comparing options that do not use earbuds, but the supplied details do not describe a sleep-specific shape or guarantee comfort while lying down. The 3.5 mm wired connection also requires a compatible headphone jack. Skip XOSDA 50 if you specifically need a black-only set or prioritize the wider stated frequency range in this comparison.

ZXQZYM is a more uniform option: the listed color is black, the connection is wired, and the headphones use a 3.5 mm jack. Its product information identifies the intended age range as kids and teens. For a classroom or group that wants a consistent appearance rather than assorted colors, that simpler setup may be appealing. The listed controls include media control operated by a remote.
The audio specifications list a dynamic driver, 32-ohm impedance, and a frequency range of 20 Hz–20,000 Hz. That range extends lower and higher on paper than the one listed for XOSDA. It may be a useful point of comparison for buyers focused on stated audio coverage, but it does not by itself establish how loud, clear, or pleasing the headphones will sound. ZXQZYM lists no noise control, so buyers should not expect a stated sound-isolation feature.
The design information describes on-ear placement and over-ear cups, along with silicone as the enclosure material. The package information lists five items, so it is not the same quantity as XOSDA’s 50-pack. The supplied details do not mention adjustable headbands, individual packaging, or a sleep-oriented design. Skip ZXQZYM if you need a large classroom quantity, multiple colors, or listed sound isolation.
• Best for a large classroom group → XOSDA 50. Its listed package contains 50 individually bagged headphones, compared with five items in ZXQZYM’s product information.
• Best for color-coding → XOSDA 50. It includes 12 colors; ZXQZYM is listed in black.
• Best for an adjustable fit across children, teens, and adults → XOSDA 50. Its retractable headband is described as adjustable for those age groups.
• Best for a wider stated frequency range → ZXQZYM Kids Headphones Bulk. Its 20 Hz–20,000 Hz range is broader on paper than XOSDA’s 80 Hz–18,000 Hz range.
• Best for a listed sound-isolation feature → XOSDA 50. Its controls information lists sound isolation, while ZXQZYM lists no noise control.
• Best for sleeping among these two designs → XOSDA 50, with an important caveat. Its soft silicone ear cushions and lightweight construction are specified, but neither product is described as designed for sleeping or side-sleeping.
• Best for a uniform black classroom set → ZXQZYM. Its listed color is black, without XOSDA’s mixed-color assortment.
• Best for a conventional 3.5 mm wired connection → either. Both list a 3.5 mm jack, so check that the intended device has a compatible headphone port.
Buying Considerations
Think first about where these headphones will be used and how many people need them. For a school, camp, or shared computer room, pack quantity and individual packaging are practical details, not minor extras. XOSDA’s listed 50-piece quantity and separate bags suit distribution across a larger group. ZXQZYM’s product information lists five items, which may fit a smaller group or a buyer who wants fewer matching pairs.
The stated frequency range can help distinguish the products on paper, not settle sound quality by itself. ZXQZYM lists 20 Hz–20,000 Hz, while XOSDA lists 80 Hz–18,000 Hz. Neither specification alone tells you how the headphones will sound to a particular listener. Both use dynamic drivers, have 32-ohm impedance, and connect through a 3.5 mm jack. Confirm that the device you plan to use has that port; the product details describe wired connectivity for both.
For anyone searching for the best hi res on ear headphones for sleeping, these specifications do not establish a high-resolution certification or sleep-specific design. Likewise, shoppers looking for with microphone ear clip headphones for sleeping should note that neither product’s supplied features list includes a microphone or an ear-clip design. If sleep is the main purpose, prioritize fit and the way an on-ear cup sits against a pillow rather than assuming either classroom set is made for that use. Check the current price on Amazon using the page’s button, then weigh it against the quantity and features you actually need.
I would choose XOSDA 50 for a classroom or group setting because its 50 individually packaged pieces, 12 colors, adjustable headbands, and stated sound isolation make it the more versatile set for distribution. For sleeping, I would lean toward XOSDA based only on its listed lightweight construction and soft silicone cushions, not because it is described as a sleep headphone. If the wider stated frequency range and uniform black appearance matter more, ZXQZYM is the more focused alternative.
FAQ
Neither product is described as sleep-specific. XOSDA lists lightweight construction and soft silicone ear cushions, which may be useful comfort considerations, but the available details do not establish how either set feels when lying down.
A microphone is not listed in the supplied features for either product. Both are wired headphones with a 3.5 mm jack, but buyers should not assume that this means a microphone is included.
XOSDA lists 50 headphones, individual packaging, and 12 colors, making it the clearer fit for a larger group that benefits from distribution or color-coding. ZXQZYM’s product information lists five items and a black color.
Its listed range, 20 Hz–20,000 Hz, is wider than XOSDA’s 80 Hz–18,000 Hz. That is a difference in the stated specification, not enough on its own to determine which headphones sound better to an individual listener.
