If you want kid-focused volume protection and a wired backup for the gym, choose iClever BTH22; if you need active noise cancellation and adult multitasking features, choose acer OHR516. For most adult gym-goers, I’d choose the Acer; for a child using headphones around family workouts or on the way to practice, the iClever’s safer volume limits matter more.
These are both over-ear Bluetooth headphones with 40 mm drivers and up to 60 hours of stated battery life, but they solve different problems. One is built around children’s listening limits; the other adds active noise cancellation and simultaneous connection to two devices.
• iClever BTH22 strength: adjustable 85 dBA sound limit, with a lower 74 dBA setting for toddlers. Trade-off: its defining features are child-focused, not ANC or adult multitasking.
• acer OHR516 strength: active noise cancellation, plus connection to two Bluetooth devices at once. Trade-off: battery life is stated as up to 40 hours with ANC on, rather than 60 hours with it off.
• Both use Bluetooth 5.4, 40 mm dynamic drivers, USB-C charging, and a 3.5 mm audio jack.
• Pick iClever for a child who needs volume limits, simple controls, and a wired fallback; pick Acer for an adult who wants ANC, calls, and easy switching between a laptop and phone.
iClever BTH22: Who It's For
The iClever BTH22 is the more clearly child-oriented choice. Its sound protection limits audio below 85 dBA, and a button combination switches to a 74 dBA level intended for toddlers. That gives parents a concrete listening-control feature to consider for a child watching a tablet during travel or waiting around before and after a workout. It also has 10 headband adjustment levels and rotating ear cups, so the fit can be adjusted rather than treated as one-size-fits-all.
I’d choose the iClever for a family that wants volume limits and a backup cable, especially for a child who listens to audio during travel or quiet periods around a gym visit. I’d skip it if your main need is blocking gym noise: the listed noise control is passive, not active noise cancellation. Its child-focused safeguards are not a substitute for gym-specific features such as ANC.
The Acer OHR516 is aimed at adult listening and multitasking. Its active noise cancellation is designed to reduce surrounding sound, while environmental noise cancellation is listed for clearer calls in busy places. Those are distinct from the iClever’s passive noise control and child-oriented volume limits. If your gym routine includes listening in a noisy space, ANC is the more directly relevant feature—though the product information does not establish how much noise it blocks in a particular gym.
The other standout is its dual-device connection. You can keep a laptop and phone connected and switch between them, which is useful if you move between a workout playlist and incoming calls or work audio. The ear cushions use breathable memory-protein foam, and the ear cups fold and rotate for storage. It weighs 229 g. Battery life is stated as up to 60 hours with ANC off and 40 hours with ANC on; a full charge takes two hours, and the description also specifies five hours of music from a five-minute charge.

For adults comparing the best headphones for gym sessions alongside commuting or work, the Acer’s broader feature set makes it the more natural fit. I’d pass if child-safe volume limits are the priority, or if you want the longest stated runtime while using noise cancellation: the listed 40-hour ANC-on figure is the one to keep in mind.

• Best for switching between a phone and laptop → acer OHR516. It can connect to two Bluetooth devices at once.

If I were choosing for a child, I’d pick the iClever BTH22 for its two volume-limit settings and wired backup.

If you want child-focused volume protection and a wired backup for the gym, choose iClever BTH22; if you need active noise cancellation and adult multitasking features, choose acer OHR516. For most adult gym-goers, I’d choose the Acer; for a child listening around family workouts or on the way to practice, the iClever’s volume limits are the more relevant feature.
Both are over-ear Bluetooth headphones with 40 mm dynamic drivers, USB-C charging, a 3.5 mm jack, and up to 60 hours of stated battery life. The key difference is their intended use: the iClever centers on children’s listening limits, while the Acer adds active noise cancellation and simultaneous connection to two devices.
• iClever BTH22 strength: two child-focused volume limits, including a 74 dBA setting for toddlers. Trade-off: it lists passive noise control, not active noise cancellation.
• acer OHR516 strength: active noise cancellation and connection to two Bluetooth devices at once. Trade-off: its stated battery life drops to up to 40 hours with ANC on.
• Both offer Bluetooth 5.4, 40 mm dynamic drivers, USB-C charging, and a 3.5 mm audio jack.
• Choose iClever for child-focused volume limits and an audio cable option; choose Acer for adult listening, ANC, and switching between a phone and laptop.
The iClever BTH22 is the more child-oriented option. It limits sound below 85 dBA, with a button combination that switches to a lower 74 dBA setting intended for toddlers. Its headband has 10 adjustment levels, and the ear cups rotate to help accommodate different fits. Those details make it a natural choice for a child listening to a tablet during a family trip or waiting before and after a workout.
It connects over Bluetooth 5.4 and can also use a 3.5 mm audio cable. That wired option is helpful when you don’t want to depend on Bluetooth or need a fallback if the battery runs out. The stated battery life is up to 60 hours, and charging takes about two hours. At 149 g, it weighs less than the Acer, though its stated design is aimed at children aged two and up.
I’d choose the iClever for a family that values adjustable, child-focused volume limits and wired listening. I’d skip it if your priority is reducing gym noise: its listed noise control is passive, not active noise cancellation. The product details also don’t list a water-resistance rating, so it isn’t a documented waterproof choice for sweaty workouts.
The Acer OHR516 is aimed at adult listening and multitasking. It includes active noise cancellation to reduce ambient sound, while environmental noise cancellation is listed for calls in busy settings. These are different from the iClever’s passive noise control and volume limits. For gym use, ANC makes the Acer the more relevant option if you want to reduce surrounding sound, but the available details don’t specify how much noise it blocks in any particular environment.
Its dual-device connection is useful if you move between a phone and laptop. You can connect to both and switch between them, which may suit someone who listens to music but also needs to take calls or join meetings. The ear cushions use breathable memory-protein foam, and the ear cups fold and rotate for storage. It weighs 229 g.
Battery life is stated as up to 60 hours with ANC off and 40 hours with it on. A full charge takes about two hours; the product details also state that a five-minute charge provides five hours of music. For an adult comparing the best headphones for gym sessions as well as commuting or work, the Acer’s feature set is broader. The trade-off is that its stated runtime is shorter when ANC is active.
• Best for child-focused volume limits → iClever BTH22. It offers an 85 dBA limit and a 74 dBA option for toddlers; the Acer’s listed features don’t include a comparable limit.
• Best for active noise cancellation → acer OHR516. The Acer lists ANC, while the iClever lists passive noise control.
• Best for switching between a phone and laptop → acer OHR516. It can connect to two Bluetooth devices at once.
• Best for a wired listening option → both. Each lists a 3.5 mm jack; the iClever’s feature details specifically describe using its audio cable when the battery is depleted.
• Best for stated runtime with ANC on → acer OHR516. It is listed for up to 40 hours with ANC active; the iClever does not list active noise cancellation.
• Best for reducing ambient gym noise → acer OHR516. ANC is more relevant to that goal than passive noise control, though the product details don’t promise complete noise blocking.
• Best for the lighter listed weight → iClever BTH22. It weighs 149 g, compared with 229 g for the Acer, and is designed with children in mind.
• Best for a child’s travel audio → iClever BTH22. Its volume settings and adjustable fit are more suited to that use than the adult-oriented Acer.
My Verdict
For a child, I’d choose the iClever BTH22 for its two volume-limit settings and wired option.

For an adult who wants noise cancellation, the Acer is the more relevant choice because it includes ANC. The iClever is better suited to child-focused listening and lists passive noise control.
No IPX7 or waterproof rating is listed for the iClever BTH22. It shouldn’t be treated as a documented waterproof option; shoppers looking for the best IPX7 waterproof earbuds for gym use should check that a product explicitly lists that rating.
The Acer is listed for up to 40 hours with ANC on and up to 60 hours with ANC off. The iClever is listed for up to 60 hours, but it does not have active noise cancellation.
