• Skullcandy Cassette — biggest strength: up to 22 hours of battery life, Rapid Charge (10 minutes for 3 hours), and a collapsible on-ear design with an included 3.5mm AUX cable for wired listening.
• Skullcandy Cassette — biggest trade-off: it's a traditional on-ear headphone aimed at an adult audience, with sound isolation rather than the awareness of your surroundings that open-ear designs provide.
• iClever OWS01 — biggest strength: air-conduction open-ear design with a 74/85 dBA volume limit, 360° bendable memory steel wire, and Bluetooth 5.4 in a shell that weighs just 0.8 oz.
• iClever OWS01 — biggest trade-off: no wired jack at all, no active noise control, and a spec sheet that's clearly tuned for kids rather than for adult listening sessions.
• Who each is for: pick the Skullcandy Cassette if you want one wireless headphone for commuting, travel and everyday music on your own ears. Pick the iClever OWS01 if the listener is a child and you care more about ear safety and situational awareness than about isolation.
The Cassette is a straightforward wireless on-ear headphone, and its most useful number is 22 hours of battery life. That's a full work week of commutes on a single charge for most people, and Rapid Charge softens the blow when you forget: 10 minutes plugged in gets you roughly 3 hours of playback. The battery itself refills in about 1.5 hours, so topping up is a short, predictable chore rather than an overnight event.
The physical design leans practical. The headband is lightweight and durable, the plush on-ear cushions pivot in multiple directions, and the whole thing collapses for travel. Importantly, an included 3.5mm AUX cable means you can plug straight in when you want a direct connection — on a plane seatback screen, on a laptop with no Bluetooth, or on a day when you simply didn't charge. Bluetooth 5.0 with a 10-meter range covers normal around-the-house movement, and the push-button controls handle calls, volume, track skipping, and rejecting calls without you digging out your phone.
Audio-wise you're looking at 40mm dynamic drivers, 30-ohm impedance, and a standard 20 Hz–20,000 Hz range — mainstream specs that suit pop, podcasts, and streaming video. The plastic enclosure keeps the weight down, and the sound isolation design is a feature, not a flaw, when you actually want to block out a bus engine. The trade-off is awareness: on-ear isolation means you're less tuned in to traffic or announcements.
Buy it if you're an adult who wants one dependable wireless headphone for music, calls, and travel, and you value the wired fallback. Skip it if you need open-ear awareness, or if the listener is a young child who needs a volume-capped, kid-sized fit.
The OWS01 approaches headphones from the opposite direction. It's an air-conduction, open-ear pair that sits outside the ear canal instead of plugging in or pressing on it. That single design decision drives everything else: because nothing blocks your ears, kids stay aware of traffic, teachers, and surroundings, and there's no in-ear pressure or hygiene issue from shared earbuds.
Two safety details matter here. First, the volume limit of 74 and 85 dBA caps how loud things can get, which is the whole point for a child's ears. Second, the ergonomic three-point pressure dispersion system spreads the load instead of squeezing one spot. At 0.8 oz, these are genuinely light — light enough that a kid is far less likely to complain after an hour. The soft TPE material is chosen to be gentle on skin, and the simple physical buttons let a child handle volume and playback without a phone in hand.
Durability is handled by a memory steel wire in the back-hanging section that allows 360° bending without deforming, which is exactly the kind of abuse a backpack or a school desk produces. The ear-hook shape and data-driven fit are meant to work across a range of head sizes rather than one. On the audio side you get 14.2mm dynamic drivers with a high-amplitude speaker design, DRC processing that lifts bass while keeping vocals clear, and 140-ohm impedance. Bluetooth 5.4 is the newest version between these two, and it pairs with phones, tablets, laptops, PCs, and smartwatches.
Buy it if you're buying for a child and want open-ear awareness, a volume cap, and a bendable, featherweight fit. Skip it if you need a wired connection, active noise cancellation, or headphones meant for adult critical listening.
Side-by-Side: Which Should You Choose?
• Best for battery life → Skullcandy Cassette. Up to 22 hours versus a battery spec the OWS01 sheet doesn't even advertise.
• Best for a child listener → iClever OWS01. Volume limits, kid-sized fit, and a kid-focused age range make this the obvious pick.
• Best for travel with a wired option → Skullcandy Cassette. The included 3.5mm AUX cable works on planes, laptops, and dead-battery days.
• Best for durability against rough handling → iClever OWS01. The 360° bendable memory steel wire is built for exactly that.
• Best for isolation from noise → Skullcandy Cassette. On-ear sound isolation blocks more of the outside world; the OWS01 has no noise control at all.
• Best for the latest Bluetooth → iClever OWS01. Bluetooth 5.4 versus Bluetooth 5.0.
• Best for adult everyday use → Skullcandy Cassette. Adult age range, on-ear cushions, and call controls suit commuting and work-from-anywhere listening.
In my opinion, the right answer depends entirely on who's wearing them, which is why I won't pretend there's one winner. If you're buying for yourself — commuting, working, traveling — I'd take the Skullcandy Cassette: 22 hours of battery, Rapid Charge, a foldable frame, and a real wired backup make it the more flexible adult headphone. If you're buying for a child, I'd take the iClever OWS01 without hesitation: the volume limit, open-ear design, 0.8 oz weight, and bendable frame are all built around a kid's ears and a kid's habits. One is an adult's all-rounder; the other is a child's safety-first headphone.
The iClever OWS01. It's explicitly designed for children with 74/85 dBA volume limiting, an open-ear fit, a 0.8 oz build, and a 360° bendable frame. The Skullcandy Cassette is listed for an adult age range and uses on-ear isolation rather than awareness.
No. The OWS01 is wireless-only with no headphone jack, while the Skullcandy Cassette includes a 3.5mm AUX cable so you can plug in directly when you want to.
The Skullcandy Cassette states up to 22 hours, with Rapid Charge giving about 3 hours from a 10-minute charge and a full charge in roughly 1.5 hours. The iClever OWS01's sheet doesn't list a battery-life figure, so I can't compare it fairly on that point.
Adults can physically wear the OWS01 — it's just tuned for kids, with volume caps and a child-sized fit. The Cassette is an adult-oriented on-ear headphone with no volume limit, so it isn't the safer choice for a young child.
