If you want a wired, on-ear design with a stated 94dB volume limit for a child who sleeps on their side, choose Bywulanda Upgrade USB Type; if you need lightweight, wireless open-ear listening for calls and everyday movement, choose RICHJOY Open Ear Earbuds. For side sleepers, the Bywulanda’s lack of a wireless charging case and its compact, foldable format make it the more plausible starting point—but neither product is specifically designed for sleeping.
• Bywulanda’s biggest strength: a 94dB volume limit, a wired USB-C connection, and a foldable on-ear design. Trade-off: it needs a compatible USB-C device and has no wireless freedom.
• RICHJOY’s biggest strength: open-ear Bluetooth listening, a lightweight C-shaped clip design, and up to 40 hours of total playtime with the case. Trade-off: it has no stated volume limit, and its on-ear clips may not suit lying on your side.
• Choose Bywulanda for a child’s tablet or phone use when the volume limit and a straightforward cable matter most.
• Choose RICHJOY for calls, workouts, and listening while staying aware of your surroundings.
• For side sleepers: Bywulanda is the more sensible of these two to consider, but neither has a sleeping-specific design or stated sleep-comfort testing.
Bywulanda is a wired, on-ear headphone for kids, with a USB-C plug and a stated 94dB volume limit. It also has 40mm dynamic drivers, a foldable frame, and an adjustable headband intended to fit from childhood through the teen years. The direct connection avoids Bluetooth pairing, and USB-C means there is no separate converter to manage when the listening device has a compatible port.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
The clearest reason to pick it is the combination of a child-focused volume limit and a simple wired setup. It may fit schoolwork, videos on a tablet, and travel where a child can stay connected to a USB-C device. Its foldable design can make packing easier, while the adjustable headband gives more room to accommodate a growing user.
It is not the right fit if you need wireless listening, a built-in microphone for calls, or headphones that work with a device lacking a USB-C jack. And although the on-ear format may be less bulky than some over-ear designs, no sleep-specific comfort information is provided. For parents searching for volume limiting headphones for side sleepers, the 94dB limit is relevant to listening level, but it does not establish that these headphones are comfortable or appropriate for sleeping.
RICHJOY takes a very different approach: these are wireless, open-ear clip-on earbuds with a C-shaped fit. Each earbud weighs 4.8 grams, and the open design leaves the ear canal uncovered. Bluetooth 6.0 connects them to compatible devices, while the case displays battery levels and the earbuds provide up to 40 hours of total playtime with the case.
Their strongest case is everyday versatility. The open-ear fit may appeal to someone who dislikes in-ear earbuds or wants to hear more of their surroundings while walking, working, or exercising. RICHJOY also lists ENC microphone noise cancellation for calls and an IPX5 rating for resistance to sweat, rain, and splashes. Those features make them more suited than Bywulanda to movement, outdoor use, and wireless calls.
The trade-off is that open-ear listening is not the same as a sealed or noise-isolating fit, and the product does not specify a volume limit. Its clip-on shape may also press against the outer ear when a person rests their head on a pillow. That makes RICHJOY a less obvious choice as a headset for side sleepers, even though its light weight and open-ear construction may be comfortable during upright, extended listening.
Side-by-Side: Which Should You Choose?
• Best fit for a child who needs a stated volume limit → Bywulanda Upgrade USB Type. Its 94dB limit is the clearest differentiator, though it does not guarantee that every listening level or use is safe.
• Best for side sleepers to consider → Bywulanda Upgrade USB Type, cautiously. It is foldable and on-ear, while RICHJOY’s C-shaped clips sit around the ears. Neither is specifically made for sleeping, so pillow pressure remains a concern.
• Best for calls → RICHJOY Open Ear Earbuds. Its ENC microphone is intended to reduce wind and background noise during calls; no microphone feature is listed for Bywulanda.
• Best for a USB-C tablet or phone → Bywulanda Upgrade USB Type. It plugs directly into a compatible Type-C port, without Bluetooth pairing or a converter.
• Best for workouts and splashes → RICHJOY Open Ear Earbuds. The product lists an IPX5 rating and a fit designed for active use. Bywulanda has no water-resistance rating listed.
• Best when you want the ear canal uncovered → RICHJOY Open Ear Earbuds. Its open-ear design avoids an in-ear fit, though that does not make it a sleep-specific product.
• Best for simple, wired listening → Bywulanda Upgrade USB Type. There is no charging case or wireless pairing to manage, but the connected device must have a USB-C jack.
I’d choose Bywulanda Upgrade USB Type for a child when the stated 94dB limit, wired connection, and foldable frame are the priorities.
For side sleepers, it is my more cautious pick of the two—not a sleep headphone, but less likely than a clip-on design to put hardware around the outer ear.
I’d pick RICHJOY Open Ear Earbuds instead for wireless calls, workouts, and open-ear listening.
The deciding question is whether you value a stated volume limit and a cable or wireless convenience and active-use features.
FAQ
Bywulanda is the more plausible option to consider because it has an on-ear, foldable design rather than C-shaped ear clips. Neither product is described as sleep-specific, and neither comes with information confirming comfort while lying on a pillow.
Bywulanda lists a 94dB volume limit. RICHJOY’s listed features do not specify a volume limit, so I would not assume it has one.
The headphones connect through USB-C and are described as compatible with devices that have a Type-C jack. A device without that port is not a direct match; the product description says a converter is not needed for compatible USB-C devices.
RICHJOY lists an ENC microphone for calls, a C-shaped clip-on fit, and an IPX5 rating for sweat, rain, and splashes. Those features suit active use, but they do not establish that the earbuds will fit every person securely or perform identically in every setting.
