If you want kid-focused earbuds with an 85 dB volume limit and a compact in-ear fit for airplane travel, choose Belkin SoundForm Nano 2; if you need an open-ear clip design, a touchscreen case, and longer stated total battery life, choose otinsile M100. For a child who needs a noise cancelling headset for airplane use, I’d lean toward the Belkin; the M100 makes more sense when awareness of your surroundings matters more than blocking them out.
• Belkin SoundForm Nano 2: Its standout is the 85 dB maximum volume limit, backed by an in-ear design and 28 hours of stated battery life; the trade-off is a shorter total battery figure than the M100.
• otinsile M100: Its strengths are the open-ear clip fit, touchscreen case, IPX7 rating, and 50 hours of stated total battery life; its trade-off for airplane use is that an open-ear design leaves the ear unsealed.
• For younger listeners: Belkin is designed for kids ages 7 and up and includes a volume limit; the M100’s listed features focus more on open-ear fit and activity use.
• For awareness on the move: The M100’s open-ear design is intended to keep surrounding sounds audible, while the Belkin sits in the ear.
• My quick pick: Choose Belkin for a child’s travel earbuds; choose the M100 if you specifically want clip-on, open-ear listening.
The SoundForm Nano 2 is the more straightforward choice for a child who needs wireless earbuds for school, games, calls, and travel. It is designed for ages 7 and up, uses an in-ear fit, and has an 85 dB maximum listening-volume limit. That volume cap is the clearest point of difference here: if your decision is about earbuds for a younger listener, it gives the Belkin a purpose-built advantage over the M100.
For a family trip, the stated battery setup is useful: up to 8 hours per earbud, with 20 additional hours from the case, for 28 hours total. A 10-minute USB-C charge is stated to provide 90 minutes of play. Bluetooth 5.3 and a listed 30-foot range cover everyday wireless pairing with a laptop, tablet, or mobile device. Environmental Noise Cancellation is specified for calls, where it is intended to reduce background noise so a parent can hear a child more clearly.

The M100 takes a different approach. Its clip-on, open-ear design does not sit inside the ear canal, and the product is described as suitable for glasses and small ears. The listed earbud weight is 4 g. For someone who dislikes in-ear earbuds or wants to hear announcements and nearby conversation while listening, that design is the main reason to consider it. It is aimed at activity use, but the same open-ear character can matter in transit.
The M100’s case has a touchscreen intended for music and call controls, volume adjustment, and camera-shutter control. It also has built-in mini-games. Bluetooth 6.0 and a listed 40-meter Bluetooth range are specified. For calls, the product lists dual-microphone ENC. Its stated battery life is 4–5 hours per charge and 50 hours total with the case; those figures describe different things, so the longer total figure does not mean a single charge lasts 50 hours.
Its IPX7 rating and clip design may appeal to someone who expects sweat or rain during outdoor activity. But for a plane, the open-ear fit is a real compromise: it does not seal the ear, and the listed features do not establish that it provides passive isolation from cabin noise. I would not choose it for someone whose main goal is to shut out the sound of the cabin or keep a child’s listening volume capped at 85 dB. The listed feature set does not specify an equivalent volume limit.
• Best fit for a child ages 7 and up → Belkin SoundForm Nano 2. It is explicitly designed for kids and has an 85 dB maximum listening-volume limit.
• Best for airplane listening where an in-ear fit is preferable → Belkin SoundForm Nano 2. It sits in the ear, unlike the M100’s open-ear clips. Neither product’s listed details establish active cabin-noise cancellation for listening.
• Best for keeping your ears open to announcements → otinsile M100. Its open-ear design is intended to let surrounding sounds remain audible.
• Best stated total battery life → otinsile M100. The case-and-earbud total is listed as 50 hours, compared with 28 hours for the Belkin. Per-charge use is stated as 4–5 hours for the M100 and 8 hours per Belkin earbud.
• Best for a quick top-up → Belkin SoundForm Nano 2. Its stated 10-minute USB-C charge provides 90 minutes of play; the M100 lists a two-hour charge time.
• Best for a touchscreen control case → otinsile M100. Its case display is described as handling music, calls, volume, and camera-shutter control.
• Best for sweat and water resistance by listed rating → otinsile M100. It carries an IPX7 rating, while the Belkin is rated IPX5. Those ratings are not a promise that either product should be used carelessly around water.
• Best with microphone headphones for airplane calls → neither is an automatic winner. Both list ENC for calls, but the Belkin describes it in the context of helping parents hear children, while the M100 specifies dual-microphone ENC. Neither fact alone proves call performance in a noisy cabin.
For the search phrase “best headset for airplane,” the key question is what you mean by “best.” If you want a child-oriented in-ear option with a defined volume ceiling, the Belkin fits that need better. If you want an open-ear fit and value awareness over blocking out surrounding sound, the M100 has the more relevant design.
My Verdict
For a child, I’d choose the Belkin because it is designed for ages 7 and up, has an 85 dB maximum volume limit, and uses an in-ear fit. The M100’s open-ear design prioritizes awareness rather than keeping surrounding sound out.
The M100 lists hybrid noise control and ENC for calls, but those details do not establish that it cancels cabin noise during music or video playback. Its open-ear design also does not seal the ear, so it is not the obvious choice if reducing the presence of cabin sound is your priority.
The M100 lists 50 hours total with its case and 4–5 hours per charge. The Belkin lists 28 hours total, including 8 hours per earbud and 20 additional hours from its case. For a single listening stretch, the Belkin’s stated per-earbud figure is longer; for total use between case charges, the M100’s figure is higher.
Both list Environmental Noise Cancellation for calls. The Belkin’s ENC is described as helping parents hear children more clearly, while the M100 lists dual microphones with ENC. Those specifications give each a call-related feature, but they do not guarantee how either will perform in a noisy airplane cabin.
