If you want wireless headphones for kids, with volume limits and long battery life, choose iClever BTH18; if you need open-ear bone-conduction headphones for swimming and phone-free playback, choose ZOVIMAX Bone Conduction Headphones. For a child listening to music, videos, or games on a tablet, I’d lean toward iClever; ZOVIMAX is built around a very different set of needs, especially water use and awareness of your surroundings.
iClever BTH18 vs ZOVIMAX Bone Conduction Headphones at a Glance
• iClever BTH18’s biggest strength: over-ear listening for kids, with selectable 74 dBA and 85 dBA volume limits and up to 43 hours of playback with the lights off. Trade-off: it is not designed for swimming or an open-ear listening experience.
• ZOVIMAX’s biggest strength: an open-ear bone-conduction design with Bluetooth and built-in MP3 playback, including underwater use in MP3 mode. Trade-off: it offers up to 12 hours of battery life, and Bluetooth does not work underwater.
• For swimming, outdoor workouts, or listening without covering the ears: ZOVIMAX is the more specialized choice.
The iClever BTH18 is an over-ear Bluetooth headset aimed at children and teens, with features suited to listening at home or while traveling. Its standout practical detail for families is the pair of selectable volume limits: 74 dBA for a lower listening level and 85 dBA for a higher one. The headset also has LED lights, and its air-hole design is described as helping produce punchy bass. That gives it a more playful look than a plain pair of kids’ headphones while keeping its main job straightforward: audio for music, videos, calls, or games.
Battery life is a strong point on paper. iClever specifies up to 43 hours of playtime with the lights off, so families who do not want to charge a child’s headphones every day may appreciate the longer interval between charges. The headset charges over USB-C and also includes a detachable 3.5 mm audio cable, giving it a wired option when Bluetooth is not the preferred connection. Bluetooth 5.3 and a listed wireless range of 33 feet cover ordinary nearby use, such as listening from a tablet in the same room.
The BTH18 weighs 5.57 ounces and has foldable construction, rotating over-ear cups, and cushions. Those details point toward a portable headset for commutes, trips, and school-age routines. It does not offer an open-ear fit, though, and the 43-hour figure is specified with the lights off; families should not assume the same playback time with the lights running.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Who should skip it: Skip the BTH18 if the main need is waterproof swimming headphones or an open-ear design that leaves the ears uncovered.
ZOVIMAX takes a different approach from the iClever. Its open-ear bone-conduction design is intended to let a listener hear audio while remaining aware of surrounding sounds, rather than sealing the ears under over-ear cups. The headset uses silicone pads and includes an adjustable strap to help secure the fit. That combination is aimed at active use, such as running and workouts, where a stable fit and an open design may matter more than child-focused volume limits or colorful lighting.
Its most distinctive feature is the combination of Bluetooth 6.0 and built-in MP3 playback. The internal memory is listed as 8 GB, with capacity for up to 2,000 songs. That allows music or podcasts to play without a phone nearby, including during swimming. The important limitation is that Bluetooth cannot function underwater: the headphones need to be switched to MP3 mode for underwater listening. ZOVIMAX lists IPX8 protection and specifies submersion up to 5 meters for as long as 2.5 hours, but that waterproof capability does not remove the need to use the correct playback mode.
Battery life is listed as up to 12 hours, and a full charge takes about two hours using the magnetic charging cable. The product description also mentions up to eight hours of continuous playback, so I would treat the longer figure as a stated maximum rather than a guarantee for every listening situation. There is no headphone jack, which makes its wireless and onboard MP3 setup central to how it is used. The included adjustable cord can help with fit, but this is listed for adults and is not presented as a kids’ volume-limiting headset.
Who should skip it: Skip ZOVIMAX if your priority is a child’s over-ear headset with selectable volume limits and a long stated battery life.
• Best for kids listening to a tablet or Chromebook → iClever BTH18. It is explicitly designed for children and supports Bluetooth as well as a detachable 3.5 mm audio cable.
• Best for selectable volume limits → iClever BTH18. Its two listed listening options are 74 dBA and 85 dBA. ZOVIMAX’s data does not specify a volume-limiting feature.
• Best for longer stated playback between charges → iClever BTH18. It lists up to 43 hours with the lights off, compared with up to 12 hours for ZOVIMAX.
• Best for swimming → ZOVIMAX. Its IPX8 design is specified for submersion, and its built-in MP3 mode works underwater. Bluetooth does not.
• Best for phone-free music → ZOVIMAX. Its 8 GB internal storage can hold up to 2,000 songs, so a phone does not have to supply the audio.
• Best for keeping ears uncovered → ZOVIMAX. The open-ear bone-conduction design is intended to let the listener remain aware of surrounding sounds.
• Best for folding and packing in a travel bag → iClever BTH18. It folds and weighs 5.57 ounces, making it the more clearly specified portable over-ear option.
• Best for a wired listening fallback → iClever BTH18. It includes a detachable 3.5 mm cable; ZOVIMAX has no headphone jack.
Start with the listener and the setting, not the most impressive-sounding feature. These headphones solve different problems. iClever is the more natural match for a child listening to ordinary audio from a tablet, Chromebook, or other compatible device. Its volume-limit options, over-ear shape, and included wired cable are relevant to family routines. ZOVIMAX is better understood as a water-and-workout headset with onboard audio storage, not as a direct substitute for a child-focused volume-limiting pair.
Think about where the audio will come from. With iClever, a listener can connect wirelessly over Bluetooth or use the supplied 3.5 mm cable. ZOVIMAX can also use Bluetooth on land, but its internal storage has a special advantage: it can play saved audio underwater, where Bluetooth cannot. If a swimmer wants a particular playlist, the songs need to be copied to the headset before use.
Battery figures deserve context, too. iClever’s maximum of 43 hours is specifically given with the LED lights off. ZOVIMAX lists up to 12 hours, while also describing up to eight hours of continuous playback. Either way, its battery capacity is more limited on the stated figures, but a two-hour full charge is specified. For a household choosing kids’ headphones for repeated daily use, the iClever’s longer stated runtime may be more convenient; for swimming, ZOVIMAX’s waterproof design and MP3 mode are more consequential than the difference in charge interval.
Finally, choose the fit that makes sense for the activity. The iClever has cushioned over-ear cups and folding construction. ZOVIMAX leaves the ears uncovered and includes an adjustable strap for a secure fit during activity. The open design is not a volume limiter, and the iClever’s over-ear design is not a swimming design. If a search for “sweatproof gaming headphones for dj” or a “volume limiting kids headset for warehouse work” led you here, check the exact use case carefully: the supplied details describe iClever as a kids’ listening headset and ZOVIMAX as a waterproof sports headset, but do not establish either as specialized DJ or workplace protective equipment. If you are comparing “headphones on sale,” check the current price on Amazon using the page’s button; the practical choice here comes down to features and fit.
In my opinion, I’d choose iClever BTH18 for the everyday for kids wireless use case. Its two volume-limit settings, 43-hour maximum playback with lights off, folding design, Bluetooth, and wired option make it the more family-oriented pick. I’d choose ZOVIMAX instead only when swimming, open-ear listening, or phone-free MP3 playback is the main need.
