If you want a larger class set of 30 wired, on-ear headphones, choose Kanayu 30; if you need a smaller 10-headphone set with an adjustable headband and inline controls, choose Hengliyuan Kids. For construction work, I’d favor Kanayu 30 when outfitting a crew, while Hengliyuan Kids makes more sense when a smaller group needs straightforward wired listening.
• Kanayu 30: Its biggest strength is the 30-headphone pack with a 3.5 mm wired connection. The trade-off is that the listed features don’t include noise control or an inline controller.
• Hengliyuan Kids: Its biggest strength is its adjustable headband, inline push-button controller, and stated passive noise cancellation. The trade-off is a smaller 10-headphone pack.
• Both are wired, on-ear headphones with a 3.5 mm jack, so neither requires wireless pairing.
• Kanayu 30 suits buyers who need more headphones in one set; Hengliyuan Kids suits smaller groups that may benefit from cable controls and an adjustable fit.
Kanayu 30 is a bulk set of 30 wired, on-ear headphones. The connection is a standard 3.5 mm jack, and the listed audio driver is dynamic, with a frequency range of 20 Hz to 20,000 Hz. That makes this a straightforward option for devices with a compatible headphone jack, rather than a wireless choice that depends on pairing or a battery.
The clearest reason to choose Kanayu is the pack size. Thirty headphones could suit a school, travel organizer, or work group that needs to equip many people at once. For construction work, that count may be useful for a crew or shared listening setup, but the listed details do not establish hearing protection, noise cancellation, or suitability as safety equipment. I would treat them as ordinary headphones, not protective gear.
The bright-color finish can also help distinguish a shared set, while the on-ear design keeps the headphones’ placement clear. The product information lists plastic enclosure material and media control, but does not describe the control method in detail. That leaves some practical questions unanswered, including how the control is operated and whether the fit is adjustable.

Who should skip it: Skip Kanayu 30 if passive noise control or a clearly specified inline push-button controller is important to you.
Hengliyuan Kids: Who It's For
Hengliyuan Kids is a 10-pack of wired, on-ear headphones with a 3.5 mm audio jack. The listed compatible devices include Chromebooks, desktop computers, laptops, smartphones, and tablets with a suitable connection. For a classroom or small group, that makes the intended use easy to understand: connect the cable to a compatible device and listen without wireless setup.
Hengliyuan lists a dynamic driver, a 40 mm driver size, 32-ohm impedance, and 92 dB sensitivity. These figures describe the audio hardware, but they don’t tell a buyer exactly how the headphones will sound in every setting. The product also lists a one-year warranty. Its 10-headphone pack is more modest than Kanayu’s, which may be an advantage for a small class or work area but a drawback when many people need a set.
Who should skip it: Skip Hengliyuan Kids if you need 30 headphones in one pack or want a wireless connection.
• Need the larger set → Kanayu 30. Its pack contains 30 headphones, compared with Hengliyuan’s 10.
• Need a smaller classroom or group set → Hengliyuan Kids. Ten wired headphones may be easier to match to a limited number of users.
• Want an adjustable headband explicitly listed → Hengliyuan Kids. Kanayu’s product details don’t specify an adjustable fit.
• Want an inline push-button controller → Hengliyuan Kids. Kanayu lists media control, but does not specify an inline controller or push-button operation.
• Want stated passive noise cancellation → Hengliyuan Kids. Kanayu lists no noise control.
• Prefer bright colors for separating shared equipment → Kanayu 30. Hengliyuan’s listed color information is less straightforward: the title describes black, while the design field lists mixed colors.
• Need wired listening with a 3.5 mm jack → Either. Both use a wired connection and list that connector.
• Need headphones for construction work → Choose based on group size, not protective use. Kanayu offers more units; Hengliyuan adds stated passive noise control. Neither product’s supplied information establishes that it protects hearing.
The search for the best bluetooth earbuds for construction work points toward a different type of product: both of these options are wired headphones, not Bluetooth earbuds. Likewise, someone seeking the best headband headphones for construction work should note that both are on-ear models with headbands, but neither is identified as safety-rated hearing protection. Hengliyuan’s adjustable headband is a useful distinction; Kanayu’s bigger pack is its practical advantage.
Buying Considerations
Start with the number of people who will use the headphones. Kanayu 30 is the more logical fit when a school, team, or organizer needs a larger set in one pack. Hengliyuan Kids provides fewer units, but its adjustable headband and inline controls may matter more if the headphones will be handled by different users or used in a classroom setting.
Next, check the connection on the devices the group will use. Both products have a 3.5 mm jack and wired connectivity. Hengliyuan lists a range of compatible device types, but the practical requirement remains the same: the intended device needs a compatible audio connection. Neither model is described as wireless, so neither is the pick for someone who wants to move around without a cable.
Think about controls and fit, too. Hengliyuan specifically lists an inline push-button controller and adjustable headband. Kanayu lists media control, but its information doesn’t state the control method or confirm adjustability. If those specifics are important, Hengliyuan’s listed details are more explicit.
Finally, keep the construction-work use case in perspective. A wired headphone can be useful for ordinary listening when connected to a compatible device, but neither data sheet identifies these models as hearing protection or supplies a safety rating. Passive noise cancellation is listed for Hengliyuan, yet that alone does not establish protection from hazardous sound. For worksite safety, follow the site’s hearing-protection requirements rather than treating either product as protective equipment.
My Verdict
In my opinion, I’d choose Kanayu 30 when the main job is outfitting a larger group: 30 wired headphones is its clearest advantage. For construction work, that makes it my pick for a crew needing shared listening equipment, not hearing protection. I’d choose Hengliyuan Kids instead for a smaller group that values its adjustable headband, inline buttons, and stated passive noise cancellation.
Kanayu 30 includes 30 headphones; Hengliyuan Kids includes 10. Choose based on how many people need a set, rather than assuming the larger pack is automatically the better fit.
The product information lists passive noise cancellation, but it gives no reduction measurement or safety rating. That does not establish that these headphones protect hearing, so don’t rely on them as worksite hearing protection.
Both are wired options with a 3.5 mm jack and could suit a group using compatible devices. Kanayu provides more units; Hengliyuan specifies an adjustable headband and inline push-button controller, which may be useful in a smaller classroom setup.
