Neither is a wireless or open-ear option, so people who need to hear nearby activity clearly should consider that before choosing. For a warehouse setup where headphones are assigned to different workers or stations, I would focus on the fit, cable reach, pack size, and whether the over-ear or on-ear design better suits the task.
Yunsailing 18 vs CNSZSLZ 20 at a Glance
• Yunsailing 18 strength: 18 individually wrapped, adjustable over-ear headphones with soft PU leather ear pads and 90-degree rotating, folding storage. Trade-off: its wired cable is approximately 3.94 feet long, and the pack is smaller than CNSZSLZ's.
• CNSZSLZ 20 strength: 20 individually packed on-ear headphones in assorted colors, with an approximately four-foot reinforced cable and a one-year limited warranty. Trade-off: the on-ear fit differs from Yunsailing's over-ear design, and the sheet does not describe folding storage.
• Choose Yunsailing 18 if you want over-ear cushions, a specified maximum sound range of 95–101 decibels, and a pink classroom-style set.
• Choose CNSZSLZ 20 if you need two additional headphones, mixed colors, and the stated warranty for a shared learning or work environment.
Yunsailing's main appeal is its over-ear design in a bulk pack. The ear pads are described as soft and made with PU leather, while the adjustable headband is intended to fit most people. For a warehouse with computer-based tasks, that design may suit workers who prefer earcups that sit around the ears rather than cushions resting on them. Each unit is individually wrapped, which gives a manager a simple way to distribute sets or keep spares separated.

The cable is approximately 3.94 feet long, and the connector is a 3.5 mm plug for compatible devices. The headphones also rotate and fold for storage. The listed sound level reaches a maximum range of 95–101 decibels; that is a specification, not a recommendation to listen at the maximum. The 18-pack makes sense for a station group that needs a consistent set, but it provides fewer units than CNSZSLZ 20.
I would consider Yunsailing if over-ear placement and compact folding storage matter more than having the largest pack. I would skip it if your setup needs a longer cable than the listed length or if you specifically want mixed colors. The product is wired, so it also will not suit someone looking for Bluetooth headphones or an open-ear design.
CNSZSLZ 20: Who It's For
CNSZSLZ takes a different approach with an on-ear fit and a 20-headphone pack. Its units are individually packed and come in assorted colors, which can help distinguish headphones assigned to different desks or users. The adjustable headband and soft cushions are described as suitable for children, teens, and adults. In a warehouse office or training area shared across shifts, the larger set may be useful when several stations need headphones at once.
The cable is reinforced and approximately four feet long, and the connection is a 3.5 mm jack. The product sheet names Chromebook, laptop, tablet, computer, and other compatible devices. It also includes a one-year limited warranty and customer support. Those details add practical reassurance for a bulk purchase, though the warranty does not tell us how a particular unit will hold up under a specific work routine.
I would choose CNSZSLZ if the extra two units, assorted colors, and stated warranty are useful to your setup. I would look elsewhere if you specifically want over-ear cups, folding storage, or a stated maximum sound range. Its on-ear design is not the same as Yunsailing's around-ear placement, so fit preference may settle the decision.
• Best for an over-ear fit → Yunsailing 18. Its listed ear placement is over-ear, with soft PU leather ear pads. CNSZSLZ is on-ear.
• Best for folding storage → Yunsailing 18. Its headphones rotate 90 degrees and fold for storage; that feature is not listed for CNSZSLZ.
• Best for a slightly longer specified cable → CNSZSLZ 20. Its reinforced cable is approximately four feet, compared with Yunsailing's approximately 3.94 feet.
• Best for assorted colors → CNSZSLZ 20. Its headphones are listed as mixed colors, while Yunsailing's are pink.
• Best for a stated warranty → CNSZSLZ 20. It includes a one-year limited warranty. No warranty detail is provided for Yunsailing in the product information here.
• Best for a specified maximum sound range → Yunsailing 18. Its listed range is 95–101 decibels at maximum; CNSZSLZ does not provide a comparable maximum level in the supplied specifications.
• Best for simple wired connections → either. Both use a 3.5 mm connection, so compatibility depends on the device having the right socket. Check your equipment before ordering.
• Best open ear earbuds for warehouse work → neither. Both are wired, cushioned headphones, not open-ear earbuds. If hearing surrounding activity is important, these designs may not match that need.
• Best spatial audio Bluetooth headphones for warehouse work → neither. Both are wired bulk classroom headphones, and neither product sheet lists Bluetooth or spatial audio.
• Best for workers who want on-ear headphones for warehouse work → CNSZSLZ 20. Its listed on-ear placement fits that preference, while Yunsailing is explicitly over-ear.
For workplace use, fit and cable management matter as much as pack count. A 3.5 mm connection is useful only if the workstation or device has a matching jack, and neither set removes the cable from the work area. If people move frequently between stations, consider whether a wired design is suitable for the job before choosing either pack.
There is also a meaningful difference between the descriptions of durability. Yunsailing lists an ABS shell and PVC cable and describes the headphones as reusable. CNSZSLZ calls its cable reinforced and says it is made for everyday classroom use. Those are product descriptions, not guarantees of service life. Neither sheet provides a comparative wear test, so I would not assume one pack will last longer based on those phrases alone.
My Verdict
I would choose Yunsailing 18 instead if over-ear placement and folding storage were higher priorities. My recommendation for warehouse work is CNSZSLZ when pack coverage matters most, but I would first confirm that an on-ear fit and a wired 3.5 mm connection suit the people and devices using it.
CNSZSLZ provides 20 headphones, two more than Yunsailing, and includes a one-year limited warranty. Yunsailing may suit a shared area better if the users prefer over-ear cups or need the folding design for storage.
No. Both are listed as wired headphones with a 3.5 mm connection. A computer or other device needs a compatible socket, so check the equipment before selecting either pack.
CNSZSLZ lists an approximately four-foot reinforced cable. Yunsailing lists an approximately 3.94-foot PVC cable, so the difference is small, but CNSZSLZ has the longer stated length.
I cannot compare their current prices here. Check the current price on Amazon before deciding, then weigh it against the details that matter to your setup: 18 over-ear headphones with folding storage from Yunsailing, or 20 on-ear headphones with mixed colors and a stated one-year limited warranty from CNSZSLZ.
