How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a pressure-free headband you can wear lying down, in bed or mid-workout, choose MUSICOZY Sleep Headphones; if you need a wired, volume-limited pair built specifically for a child’s head and road trips, choose Skullcandy Grom. These two sit in completely different corners of the slim on-ear headphone world, and that difference is the whole story.
• MUSICOZY's biggest strength: a headband-plus-eye-mask design with ultra-thin speakers that sit flat against your ears instead of pressing on them — ideal for side sleepers and anyone who hates earbuds digging in.
• MUSICOZY's biggest trade-off: sound is built for quiet listening, not critical audio; there's no active noise cancellation and no wired fallback, so it lives and dies by its Bluetooth connection.
• Skullcandy Grom's biggest strength: a genuine kid-first build — volume limited to a kid-safe 85 decibels, an adjustable headband, kid-specific over-ear cups and a Share Audio Port for two listeners.
• Skullcandy Grom's biggest trade-off: it's wired only, with a 3.5mm AUX plug, so there's no Bluetooth freedom and no wireless range despite the Bluetooth field on the spec sheet.
• Who MUSICOZY is for: adults and teens who want comfortable, low-profile audio for sleep, travel, meditation and light exercise.
• Who Skullcandy Grom is for: kids aged 6+ who need durable, volume-limited headphones for travel, school runs and shared screen time.
Think of MUSICOZY Sleep Headphones less as a headphone and more as a wearable. The design combines a Bluetooth headband and an eye mask, with ultra-thin HD stereo speakers tucked inside soft fabric. That means nothing presses into your ears the way earbuds or on-ear cups do — the sound just floats against them. If you've ever woken up with sore ears from rolling onto a bud, that single design choice is the reason to care.
The spec sheet backs up the comfort angle. The headband is breathable, elastic and washable, and MUSICOZY pitches it for a wide range of head shapes. Bluetooth 5.4 compatibility covers modern phones, tablets and laptops, and there's a built-in microphone for voice calls. Battery life is rated at 14 hours with a 2-hour charge time, and wireless range is around 33 feet, so you can leave your phone on the nightstand and still move around the room.
Where it fits best: sleep, meditation, long flights, yoga, jogging, cycling and workouts. The IPX6 water resistance rating means sweat and light rain aren't a problem, which is why it doubles as a sports headband. The skull-print styling is aimed at younger buyers who want it to look like an accessory, not medical gear.
Who should skip it? If you want serious sound quality, punchy bass or noise cancellation, this isn't the product. Noise control is listed as "None," and the driver is a single dynamic unit tuned for thin, comfortable playback. It's also wireless-only — no 3.5mm jack — so you're dependent on Bluetooth. And while the fit is stretchy, it's a fabric band, not a precision audio instrument. Buy it for comfort and convenience, not fidelity.
Skullcandy Grom is a different animal entirely, and honestly, a more honest one for its purpose. It's a wired over-ear headphone designed for kids aged 6 and up. The headline feature is volume limiting to a kid-safe 85 decibels, with a Volume Limit Override for loud environments like airplanes. That's the kind of feature parents actually search for, and it's baked into the design rather than tacked on.
The build is kid-specific. Kid-sized ear cups and an adjustable headband strap are meant to fit smaller heads properly instead of sliding around. It folds flat for travel, uses a 3.5mm AUX cable for a direct plug-in connection, and weighs 140 grams — light enough that a child won't complain on a long car ride. Materials are plastic and TPE, which is a sensible choice for something that will get tossed in a backpack.
Then there's the Share Audio Port, which lets two kids plug in and watch the same movie on a tablet or seatback screen. If you've ever refereed a fight over one pair of earbuds on a road trip, you understand why that matters. There's also a built-in microphone with call and media controls, plus voice assistant activation.
The trade-offs are real, though. It's wired, full stop — the AUX cable is the connection. There's no active noise cancellation, only passive isolation from the over-ear cups, and no wireless freedom. The 45-hour battery figure on the spec sheet is odd for a wired headphone, so I wouldn't lean on it; treat this as a plug-in device. And while the frequency range spans 20 Hz to 20,000 Hz, this is a kid-tuned headphone, not an audiophile one.
Who should skip it? Adults. The cups are sized for children, and the volume limiting — while great for kids — will frustrate anyone who wants to crank their music. If you're an adult looking for slim on-ear headphones, this isn't your pick.
Side-by-Side: Which Should You Choose?
• Best for kids → Skullcandy Grom. Volume limiting to 85 dB, kid-sized cups and a 1-year manufacturer warranty make it the obvious child-first choice.
• Best for workouts and sweat → MUSICOZY Sleep Headphones. IPX6 water resistance and a washable, elastic band handle sweat far better than a plastic over-ear frame.
• Best for shared listening → Skullcandy Grom. The Share Audio Port lets two kids listen to one device — MUSICOZY has no equivalent.
• Best for travel with a child → Skullcandy Grom. It collapses flat, plugs into any 3.5mm seatback jack, and needs no charging.
• Best for hands-free calls → MUSICOZY Sleep Headphones. Bluetooth with a built-in mic and 33-foot range beats a tethered wired connection for calls.
• Best for battery life → MUSICOZY Sleep Headphones. A rated 14 hours per 2-hour charge gives you freedom from cables overnight or through a long flight.
• Best for fuss-free setup → Skullcandy Grom. Plug in the AUX cable and it works — no pairing, no charging, no app.
In my opinion, the right pick depends entirely on who's wearing them — and that's not a cop-out, it's the whole point of this comparison. If you're an adult who wants slim on-ear headphones for sleep, meditation or workouts, I'd buy MUSICOZY Sleep Headphones. The headband design, IPX6 rating and 14-hour battery solve real problems that over-ear cups can't.
If you're buying for a child aged 6+, I'd buy Skullcandy Grom every time. Volume limiting to 85 dB, a collapsible kid-sized build and the Share Audio Port are purpose-built features you won't find on an adult headband. Don't buy either one for the other's job.
are on ear headphones good
On-ear headphones can be good for portability and lightweight listening, but they press against the outer ear, which some people find uncomfortable over long sessions. The MUSICOZY headband avoids that pressure entirely by using ultra-thin speakers in fabric, while the Skullcandy Grom uses over-ear cups with passive noise isolation. Which is "good" depends on whether you prioritize comfort, isolation or a secure kid-friendly fit.
are on ear headphones comfortable
Comfort varies by design and head shape. MUSICOZY markets its headband as breathable, elastic and suitable for various head shapes, with no ear pressure — a plus for side sleepers. The Skullcandy Grom uses an adjustable headband strap and kid-specific ear cups sized for children aged 6+. If pressure on the ear bothers you, the fabric headband approach is usually the gentler option.
are headphones less harmful than earphones
Volume and listening duration matter more than the type of device. The Skullcandy Grom is volume limited to a kid-safe 85 decibels with a Volume Limit Override for loud environments, which is the clearest safety feature between these two. MUSICOZY doesn't list noise control or a volume cap, so the listener controls the level. Neither design replaces sensible listening habits.
what are the best open ear headphones
Neither of these is a true open-ear design, so I wouldn't call either one that. MUSICOZY Sleep Headphones sit closest to the concept — ultra-thin speakers rest against the ear inside a headband rather than sealing it off. The Skullcandy Grom is a closed over-ear headphone with passive noise cancellation. If open-ear is your priority, look for products explicitly described that way.
