How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a pair of Bluetooth headphones built specifically for a child's ears, choose New Bee Kids; if you need to get wireless audio out of an airplane's seat-back entertainment jack, choose Nulaxy Air in-Flight. These two products share the word "Bluetooth," and that's about where the overlap ends. One is a kids' on-ear headphone with a hard volume ceiling. The other is a tiny adapter that turns any 3.5mm socket — including the one in your seat armrest — into a Bluetooth transmitter. The right pick depends entirely on what you're actually trying to solve.
• New Bee Kids — biggest strength: Capped at 94dB with padded on-ear cushions, Bluetooth 5.0, a built-in mic and up to 32 hours of playback. It's a complete listening device for a child.
• New Bee Kids — biggest trade-off: It's a headphone, not an adapter. It can't make a plane's seat-back screen wireless on its own — it only connects to devices that already broadcast Bluetooth.
• Nulaxy Air in-Flight — biggest strength: It plugs into a 3.5mm jack and transmits that audio to up to two pairs of Bluetooth headphones at once — designed exactly for airplane seat-back ports.
• Nulaxy Air in-Flight — biggest trade-off: It produces no sound by itself. Without Bluetooth headphones to pair with, it does nothing, and it isn't meant for instruments or live music.
• Who New Bee Kids is for: Parents buying a safe, comfortable, self-contained headphone for a kid's tablet, schoolwork or travel.
• Who Nulaxy Air in-Flight is for: Travelers (or anyone with a wired audio source) who want to use their own wireless headphones with a 3.5mm jack.
The New Bee Kids headphone is built around one idea: let a child listen without you worrying about the volume. The 94dB limit is the headline. That ceiling keeps the output at a level generally considered safer for young ears, and it does so automatically — no app, no parental menu, no negotiation. In my opinion that single feature is what makes this a kids' product rather than a small adult headphone.
Around that core, the rest of the design supports everyday kid use. The earcups are on-ear with memory foam cushions and a fully adjustable, padded headband, so the fit is meant to stay comfortable over a long session rather than clamp down. Bluetooth 5.0 handles the wireless connection with a stated range of about 10 meters, and there's a built-in microphone plus on-unit controls for play, pause and calls — handy for online classes or video chats. Battery life is listed at up to 32 hours, charged over USB-C, and there's an included audio cable so it can run wired when you'd rather not rely on Bluetooth at all. The materials are described as EU RoHS-compliant and toy-grade, which matters for something that will get dropped, sat on and chewed near.
So who should buy it? Parents of younger kids who need a headphone for a tablet, a Fire tablet, a school device or a long car ride, and who want the volume question handled for them. Who should skip it? Anyone shopping for themselves, or anyone hoping a single purchase will let them use wireless headphones with an airplane's seat-back screen. This headphone only receives Bluetooth — it doesn't create it, and it won't bridge a wired jack. If that's your goal, it's the wrong tool entirely.
The Nulaxy Air in-Flight is a completely different category of product, and it's worth being blunt about that. It's a 2-in-1 Bluetooth transmitter and receiver with a 3.5mm plug. In transmitter mode it takes audio from a wired source — a TV, an airplane seat-back jack, a gym machine, a gaming console, a projector, a home stereo — and broadcasts it to Bluetooth headphones. In receiver mode it does the reverse, letting a wired speaker or car stereo play audio sent from your phone. It is not a headphone. It makes no sound on its own.
The feature that earns it the "in-flight" name is dual-headphone sharing: it can connect two pairs of Bluetooth headphones to the same source at once. That's the difference between one person watching a movie on a plane and two people watching it together. The spec sheet also calls out AirPods compatibility specifically, with the note that AirPods need to sit in their case to enter pairing mode, and that you should switch off nearby Bluetooth devices — like your phone — when pairing on a plane so the adapter isn't fighting for the connection. Battery life is listed at up to 20 hours in receiver mode and up to 15 hours in transmitter mode, recharged via the included Type-C cable. It's light — well under a tenth of a kilogram — and small enough to live in a seat-back pocket.
The honest limitations are spelled out by the brand itself: it isn't for pianos, drum sets or guitars, it can't be used in a car in transmitter mode, and it isn't recommended for live music or karaoke where tight audio sync matters. It also tops out at two simultaneous Bluetooth connections. Who should buy it? Frequent flyers who own good Bluetooth headphones and want to use them with the plane's entertainment system — especially couples or families sharing one screen. Also anyone who wants to make a TV, gym treadmill or older stereo wireless. Who should skip it? Anyone who doesn't already own Bluetooth headphones, and anyone expecting it to work as a standalone audio device.
Side-by-Side: Which Should You Choose?
• Best for a child's safety and comfort → New Bee Kids. The 94dB cap and padded on-ear fit are purpose-built for kids; the Nulaxy has nothing to do with a child's listening.
• Best for sharing one screen with two people → Nulaxy Air in-Flight. It pairs with two Bluetooth headphones at once.
• Best for battery life → New Bee Kids. Up to 32 hours per charge versus up to 20 hours in receiver mode and 15 in transmitter mode for the Nulaxy.
• Best all-in-one gift for a kid → New Bee Kids. It's a finished product out of the box — headphone, mic, cable, controls. The Nulaxy is a component that needs a partner device.
• Best for making a TV, gym machine or old stereo wireless → Nulaxy Air in-Flight. Its 3.5mm transmitter/receiver role covers all of those; the New Bee is just a headphone.
• Best for wired fallback → New Bee Kids. It ships with an audio cable, so it still works when Bluetooth isn't an option.
• Best if you want zero setup → New Bee Kids. Charge it, pair it, done. The Nulaxy sometimes needs a reset (hold the mode button for 8 seconds while off) and careful pairing order.
If I had to pick one, I'd pick based on the job, not the brand. For a child — my pick is the New Bee Kids, because the 94dB limit, the 32-hour battery and the toy-grade, RoHS-compliant build are exactly what a parent is shopping for, and it works the moment you unbox it. For an adult who already owns Bluetooth headphones and wants them to work on a plane, my pick flips to the Nulaxy Air in-Flight, because it solves a problem the New Bee simply cannot touch. In my opinion these aren't competitors so much as two answers to two different questions — buy the one that matches yours.
are bluetooth headphones allowed on flights
Yes. Bluetooth headphones are permitted on commercial flights for listening to your own devices or a paired in-flight system. The catch is that many seat-back entertainment screens still use a wired 3.5mm jack, so a Bluetooth headphone can't connect to them directly — that's the specific gap the Nulaxy Air in-Flight adapter is designed to close.
do bluetooth headphones work on flights
They work for anything that broadcasts Bluetooth, such as your phone, tablet or laptop. They don't automatically work with an airplane's built-in screen, because that audio usually comes out of a wired port. To bridge that, you need a transmitter like the Nulaxy, which plugs into the 3.5mm jack and sends the audio to up to two pairs of Bluetooth headphones.
do delta flights have bluetooth for headphones
This varies by aircraft and entertainment system, so it's worth checking before you fly. Regardless of the airline, the reliable approach is to carry a 3.5mm Bluetooth transmitter: if the seat has Bluetooth, you pair directly; if it only has a wired jack, the adapter handles it. Either way you're covered.
are bluetooth headphones ok on flights
They're fine — the restriction people sometimes remember is about transmitting during takeoff and landing, and even that has loosened on most carriers. For a child, the New Bee Kids' 94dB cap and 32-hour battery make it a sensible travel headphone; for an adult wanting to use the seat-back screen, add a Nulaxy adapter and you're set.
