ONTA’s 3.5 mm connection and adjustable headband fit school, travel, and shared-device routines, while Monster offers Bluetooth, an open-ear design, and up to 24 hours of listening with its charging dock. Neither product lists a microphone in its supplied specifications, so check that requirement carefully before deciding.

• ONTA Kids Headphones: A child-oriented, adjustable wired headset with a 3.5 mm plug; the trade-off is that it needs a compatible headphone jack and lists no microphone.
• Monster Open Ear AC360: Wireless open-ear listening, touch control, and up to 8 hours per charge or 24 hours with the charging dock; the trade-off is that it is described for adults, not children.
• For school, tablets, and travel: ONTA suits kids using devices with a 3.5 mm jack, with foldable construction and removable padding.
• For calls and active use: Monster is the more relevant fit, with stated HD-call noise filtering, IPX5 water resistance, and Bluetooth 6.0.
• Choose ONTA for a straightforward wired headset sized and designed around children; choose Monster for wireless listening that leaves the ears open.
ONTA is built around the practical needs of a child’s everyday listening. Its adjustable headband is intended to accommodate growing kids, while the flexible headband and lightweight foldable design make it easier to pack for school, a car trip, or a flight. The ear padding is removable for cleaning, a useful detail when headphones move between home and a backpack.
The 3.5 mm wired connection works with compatible phones, tablets, laptops, and other devices that have that jack. That makes ONTA a sensible option for families who want to avoid Bluetooth pairing or recharging. Its stated frequency range is 20 Hz–20 kHz, and the headset has a media control. The product information also describes food-grade materials and child-focused construction. Those details may appeal to parents considering a headset for younger users, though they do not add a microphone.

For the specific search of kids headphones with microphone, there is an important catch: the supplied ONTA details do not specify a microphone. It may be usable for listening, but I would not choose it for online classes or calls that require a confirmed mic without checking the actual unit’s capabilities first. Skip ONTA if you need wireless use, a verified microphone, or a device without a 3.5 mm headphone jack.
Monster takes a different approach: it is an adult-oriented, open-ear Bluetooth headset rather than a child’s over-ear set. Its open-ear placement leaves the ear canal uncovered, and the listed touch controls let the wearer manage the headset without a cable remote. Bluetooth 6.0 is specified for wireless connection to compatible devices, including smartphones and TVs. There is no headphone jack, so wired listening is not an option.
For people who want to use headphones while moving around, the stated IPX5 water resistance is intended to handle rain and sweat. The product also describes an ergonomic, lightweight fit designed to stay in place during exercise. Its battery is listed for up to 8 hours of use at a time, with up to 24 hours when the charging dock is included. Those figures make it a practical candidate for a long day away from a wall outlet, provided the wearer is comfortable keeping the dock available for additional charge.
Monster also claims HD calls supported by DNN noise-filtering technology. That makes it the more relevant choice of these two for call-focused use, although the specifications do not identify a microphone type or provide measured call performance. Open-ear listening can suit someone who prefers not to seal off the ears, but it is not a noise-cancelling design; the listed noise control is “None.” Skip Monster if you need child-specific sizing, a wired connection, or headphones that block outside sound.
• Best fit for younger children → ONTA Kids Headphones. Its adjustable headband, child-focused design, and removable padding are specific to kids’ use.
• Best for a Bluetooth-only device → Monster Open Ear AC360. It connects wirelessly over Bluetooth 6.0 and has no headphone jack.
• Best for a device with a 3.5 mm jack → ONTA Kids Headphones. Its wired plug avoids Bluetooth setup and charging.
• Best stated battery endurance → Monster Open Ear AC360. It is specified for up to 8 hours per charge and up to 24 hours with the charging dock.
• Best for sweat or rain exposure → Monster Open Ear AC360. Its IPX5 rating is described as protection against rain and sweat.
• Best for packing in a child’s school bag → ONTA Kids Headphones. The set folds for storage and is described as lightweight.
• Best for a confirmed microphone? → Neither is a sure pick from the supplied details. Monster lists HD-call noise filtering, but neither product’s specifications clearly identify a microphone.
• Best for noisy environments → Neither is presented as noise-cancelling. Both list no noise control, so don’t expect either to block surrounding sound.
If you are searching for the best open ear headphones for call center work, Monster’s open-ear design and stated HD-call filtering make it the closer match here, but the product details do not establish performance in a busy call-center environment. If you’re shopping for the best gaming headset for toddlers, ONTA is more age-aligned, but its listed specs do not confirm a microphone or gaming-specific features. And if you want noise cancelling sports earbuds for library use, neither fits that description: Monster is water-resistant and open-ear, while both list no noise control.
Start with the device connection. ONTA needs a 3.5 mm jack; Monster needs Bluetooth. A phone or tablet without a headphone jack may require a separate adapter to use ONTA, while a device that does not support Bluetooth will not suit Monster as described. The choice is not just about sound or wearing style: it determines which devices the headset can connect to.
Next, think about who will wear the headphones and where. ONTA is made with children in mind and has an adjustable headband, foldable design, and removable padding. Monster is described as an adult headset, with an open-ear fit and features aimed at wireless calls and active use. An adult-oriented fit should not be assumed to work well for a child simply because the product is lightweight.
Finally, treat microphone needs as a must-confirm item. Monster’s call-filtering feature points toward voice calls, but the supplied details do not explicitly list a microphone. ONTA’s details do not list one either. For classes, gaming, or regular calls, verify microphone support for the exact device and use case before buying. Also consider the listening environment: neither model lists noise control, and Monster’s open-ear format is designed to leave the ears uncovered rather than isolate the listener.
In my opinion, I would choose ONTA Kids Headphones for a child who needs a simple, wired headset for compatible school or travel devices. Its adjustable, foldable design and removable padding make it the more child-focused option. For kids with microphone use, though, I would confirm microphone support before committing: neither product’s supplied specifications clearly guarantee one. Choose Monster instead if wireless calls, open-ear wear, and water resistance matter more than child-specific design.
FAQ
No noise-cancelling feature is listed; its noise control is specified as “None.” Its open-ear design leaves the ears uncovered, so it is not intended to isolate the listener from surrounding sound.
ONTA folds for storage and connects by a 3.5 mm plug, so there is no battery to recharge. Monster is wireless and lists up to 8 hours per charge, or up to 24 hours with its charging dock; the better fit depends on whether you prioritize wired simplicity or wireless use.
Monster is the more call-oriented option because it describes HD calls with DNN noise filtering. However, its supplied details do not identify the microphone itself, so confirm it meets your calling needs before purchase. ONTA’s specifications do not list a microphone.
