If you want a playful, kid-focused pair of wired headphones with a cat-ear design and safe volume limits, choose iClever HS25; if you need open-ear, wireless headphones for running, cycling and workouts with bone conduction tech and all-day battery, choose PSIER Bone Conduction Headphones.
• iClever HS25 biggest strength: A fun cat-ear design built for kids, with wired 3.5mm plug-and-play simplicity and a 40mm dynamic driver.
• iClever HS25 biggest trade-off: It's wired only, has no active noise cancellation, and its appeal is aimed squarely at toddlers and younger kids.
• PSIER Bone Conduction Headphones biggest strength: Open-ear bone conduction sound, Bluetooth 6.0 wireless freedom, IPX5 sweat/rain resistance, and up to 10 hours of playtime.
• PSIER Bone Conduction Headphones biggest trade-off: Open-ear design means you don't get the isolation of closed cups, and it's clearly aimed at adult athletes rather than children.
• Who iClever HS25 is for: Parents buying a first pair of headphones for a toddler or young child who wants something cute, safe and simple.
• Who PSIER Bone Conduction Headphones is for: Adult runners, cyclists, gym-goers and commuters who want to stay aware of their surroundings while listening wirelessly.
The iClever HS25 is unapologetically a kids' product. Everything about it — the Hot Pink colorway, the cat-ear earpiece shape, the "Meow Lollipop" model name, even the stickers and user manual that come in the box — signals that this is designed for children, not adults. The build uses ABS plastic with a leather carrying case, and at 130g it's light enough that a small head won't feel weighed down. It's an on-ear design with a 40mm dynamic driver, a 32 ohm impedance, and a 20 Hz–20,000 Hz frequency range, which is a standard full-range spec you'd expect from a kids' headphone.
The most important thing here is the wired 3.5mm jack. There's no pairing, no charging routine, no Bluetooth dropouts — you plug it into an iPad, tablet, laptop or phone and it works. For a parent handing a device to a four-year-old, that simplicity is the feature. iClever also markets this with its "SafeSound Tech 3.0" positioning and highlights that the materials are free of BPA and heavy metals, which is the sort of thing parents of toddlers actually care about. The cat ears light up in three modes, which is a small thing that makes a big difference to the kid holding them.
Who should skip it? Anyone who wants wireless audio, anyone who needs noise cancellation (this model has none — the noise control field is literally "None"), and any adult who wants to use headphones for themselves. The touch volume control and button controller are kid-friendly, but the whole package is built around a young audience. If you're shopping for a teenager or an adult, this isn't the pick.
The PSIER X23 is the opposite kind of product in almost every way. It's an adult, open-ear, wireless headphone built around bone conduction — meaning the drivers transmit sound through your cheekbones rather than sealing over your ear canal. That open-ear design is the entire point: you keep your ear canals free for airflow and, more importantly, you stay aware of traffic, other runners and your surroundings. For running, cycling, hiking and gym work, that situational awareness is a genuine safety feature, not a gimmick.
The spec sheet backs up the athletic positioning. It weighs just 23g, uses a flexible memory-titanium frame that contours to your head, and includes an adjustable strap for different head sizes. It's IPX5 rated, so sweat and sudden rain are fine (though PSIER explicitly notes it's not for underwater use). The 13mm bone conduction drivers run at 10 ohm impedance with 90 dB sensitivity, and the frequency range covers the same 20 Hz–20,000 Hz span as the iClever. Connectivity is Bluetooth 6.0 with a stated 33 ft range and 60 ms low latency, and battery life lands at up to 10 hours at 50% volume, with a 2-hour Type-C charge and a 200-hour standby figure.
There's also a companion app angle: PSIER mentions the Boean App for adjustable EQ (Bass Boost, balanced vocals, genre profiles) and even AI-generated song creation. Whether that matters to you is personal, but the EQ control is the practically useful part. Controls are push-button, and noise control is listed as passive, which is honest — bone conduction headphones don't isolate you from the world by design.
Who should skip it? Anyone buying for a small child. The age range is listed as adult, the fit is designed around adult head sizes, and open-ear bone conduction is really a fitness and outdoor format rather than a kids' format. If you want sealed, immersive listening for a flight or a noisy office, this isn't the tool either.
• Best for young kids → iClever HS25. Cat-ear styling, BPA-free materials, and a wired 3.5mm plug that any parent can hand over without setup.
• Best for running, cycling and workouts → PSIER Bone Conduction Headphones. Open-ear awareness, IPX5 sweat resistance, and a 23g memory-titanium frame.
• Best for battery life → PSIER Bone Conduction Headphones. Up to 10 hours of playtime plus 200 hours of standby, versus a wired headphone that draws nothing.
• Best for zero-setup simplicity → iClever HS25. No pairing, no charging, no app — just plug in.
• Best for wireless freedom → PSIER Bone Conduction Headphones. Bluetooth 6.0 with a 33 ft range and 60 ms low latency.
• Best for hearing your surroundings → PSIER Bone Conduction Headphones. The open-ear design leaves your ear canals free, and PSIER states it reduces sound leakage by up to 50%.
• Best for sound customization → PSIER Bone Conduction Headphones. The Boean App offers Bass Boost, balanced vocals and genre-specific EQ profiles.
• Best as a gift for a child → iClever HS25. The stickers, cat ears and light modes are built for exactly that moment.
In my opinion, these two don't really compete — they solve completely different problems, and the right answer depends entirely on who's wearing them. If you're buying for a toddler or young child, I'd choose the iClever HS25: the wired 3.5mm connection removes every failure point a parent worries about, and the kid-friendly design is the whole point. If you're an adult who runs, cycles or trains and wants to hear traffic while you listen, I'd choose the PSIER Bone Conduction Headphones — the open-ear design, IPX5 rating and 10-hour battery are exactly what that use case demands. My honest pick for most readers landing on this page as an adult shopper is the PSIER. Check the current price on Amazon before you commit.
how to headphones work
Traditional headphones like the iClever HS25 push sound through a 40mm dynamic driver into your ear. Bone conduction headphones like the PSIER X23 work differently: they vibrate against your cheekbone and send the sound through the bone directly to your inner ear, bypassing the eardrum and leaving your ear canal open.
how to headphones on iphone
The iClever HS25 connects to an iPhone through its 3.5mm jack — though newer iPhones without a headphone port need an adapter. The PSIER X23 pairs over Bluetooth 6.0, so you'd connect it through your iPhone's Bluetooth settings instead.
how to headphones noise cancelling
Neither of these two offers active noise cancellation. The iClever HS25 lists noise control as "None," and the PSIER X23 uses passive noise cancellation — meaning it doesn't actively block sound. In fact, the PSIER's open-ear design is intentionally built to let outside sound in for safety.
how to headphones
The short version: figure out your use case first. For a child who needs something simple and wired, the iClever HS25 plugs straight in. For an adult who wants wireless, sweat-resistant, open-ear audio for exercise, the PSIER X23 pairs over Bluetooth and runs up to 10 hours per charge.
