If you want lightweight, sweat-friendly earbuds that clip around your neck and keep you listening all day, choose AMORNO Headphones; if you need a small adapter that turns any old 3.5mm jack into Bluetooth and lets two people share the sound, choose Twelve South AirFly Pro 2.
• AMORNO Headphones — biggest strength: an ergonomic neckband with auto-retractable earbuds, Bluetooth 5.0 with dual-device pairing, and a claimed 16 hours of music playtime per 3.5-hour charge.
• AMORNO Headphones — biggest trade-off: it's a self-contained pair of earbuds, so you're locked into its own sound and fit — it can't route audio from a screen or stereo that has no Bluetooth.
• Twelve South AirFly Pro 2 — biggest strength: Bluetooth 5.3 with aptX HD Adaptive support in a tiny transmitter/receiver that turns an airplane screen, gym TV, or car AUX port into a wireless source, and pairs two headphones at once.
• Twelve South AirFly Pro 2 — biggest trade-off: it makes no sound of its own — you still need your own wireless headphones, and it only helps when there's a 3.5mm jack to plug into.
• Who AMORNO is for: travelers and gym-goers who want one lightweight headset to wear and forget.
• Who AirFly Pro 2 is for: anyone who already owns AirPods or other Bluetooth headphones and wants to use them with wired entertainment systems.
The AMORNO Headphones are a neckband-style Bluetooth headset, and that shape is the whole point. The band rests on your shoulders instead of clamping your skull, and the silicone build keeps the weight down — the sheet lists the product at roughly 0.19 kg. The earbuds themselves retract: pull the wire out to the length you want, press the button, and it rolls back in. That's a genuinely useful trick on a plane tray table or in a gym bag, because there's no loose cable to untangle. A pouch bag is included for exactly that kind of on-the-go carrying.
On the spec side, this is a Bluetooth 5.0 headset with a dynamic driver covering 20 Hz to 20,000 Hz, a 10-meter wireless range, and no headphone jack at all — it's wireless-only. It supports connecting to two devices at the same time, which is handy if you want your laptop and phone both live. The battery figures are the headline for me: 16 hours of music, 18 hours of talk, and 300 hours of standby from a 3.5-hour charge. Battery status shows up on your connected device, so you're not guessing. There's also a vibration alert for incoming calls, which matters more than it sounds — in a noisy airport or on a treadmill, a buzz on your neck beats a ringtone you can't hear.
Twelve South AirFly Pro 2: Who It's For
The AirFly Pro 2 is a different category of product entirely, and it's worth being blunt about that. It's a Bluetooth adapter about the size of a small marker — the sheet lists dimensions of 0.43" x 1.3" x 4.25" — and it exists to solve one specific, very common travel problem: the screen in front of you has a 3.5mm headphone jack and nothing else. Plug the AirFly into that jack, flip it into transmit mode, and your AirPods or other Bluetooth headphones receive the audio. No wires running from the seatback to your face.
The spec sheet backs this up properly. It runs Bluetooth 5.3 with aptX HD Adaptive support and low-latency audio, which is the part that matters for lip-sync when you're watching a movie or gaming. It supports dual pairing, so two sets of Bluetooth headphones can connect at once — one for you, one for whoever's sitting next to you. Dedicated pairing buttons make adding that second pair straightforward rather than a menu-diving exercise. Push-button controls handle volume and mute directly on the device.
Battery is the other strong card: over 25 hours per charge, helped by the deliberate decision to skip a display and spend that space on capacity instead. The sheet also notes routine care advice — use it 30–60 minutes a month and don't let it fully discharge during long storage, charging to about 50% if you're putting it away. It's worth knowing that. Flip it to receive mode and it works the other direction too: your phone streams into a car or boat AUX port, upgrading an older stereo without replacing it. Compatible targets include airplane entertainment systems, car stereos, gym machines, laptops, and classic stereo hardware.
Buy it if you already own wireless headphones you love and you keep running into 3.5mm jacks — flights, hotel gyms, rental cars, a friend's old receiver. Buy it if you travel with a companion and want to share one screen's audio. Skip it if you don't own Bluetooth headphones yet, because the AirFly adds nothing on its own. Skip it if you want something to wear; this lives in a tech pouch, not on your head.
• Best for all-day listening without a recharge → AMORNO Headphones (16 hours music, 18 hours talk, 300 hours standby).
• Best for flights where the seatback screen is the only source → Twelve South AirFly Pro 2 (3.5mm AUX in, Bluetooth 5.3 out).
• Best for sharing audio with a seatmate → Twelve South AirFly Pro 2 (dual pairing with dedicated pairing buttons).
• Best for workouts and outdoor sports → AMORNO Headphones (sweatproof, lightweight, retractable earbuds that stay out of the way).
• Best for hands-free calls in loud places → AMORNO Headphones (CVC 6.0 noise filtering plus a vibration ring alert).
• Best for upgrading an older car or home stereo → Twelve South AirFly Pro 2 (receive mode streams your phone into an AUX port).
• Best for movie and gaming lip-sync → Twelve South AirFly Pro 2 (aptX HD Adaptive and low-latency support).
• Best if you want one purchase and nothing else to own → AMORNO Headphones, because the AirFly assumes you already have headphones.
If I had to pick one, I'd buy the Twelve South AirFly Pro 2 — but only because of what I already own. In my opinion, it's the more versatile tool: it makes the headphones you already like work in places that were never designed for them, and the 25+ hour battery and dual pairing make it genuinely useful rather than a novelty. That said, if you don't have Bluetooth headphones yet, the AMORNO is the smarter single purchase — it's the complete package, and the retractable neckband design plus long battery life make it a strong everyday headset for travel and sport. If you're the kind of traveler who keeps hitting wired screens, go AirFly. If you want one thing to wear, go AMORNO.
Both help, in different ways. The AMORNO gives you 16 hours of music from its own battery and needs no other gear. The AirFly Pro 2 only helps if the plane's screen has a 3.5mm jack and you already own Bluetooth headphones to pair with it.
No. It's a transmitter and receiver, not a speaker or earbud — it has no audio output of its own. You need AirPods, Beats, Sony, or any other Bluetooth headphones connected to it for anything to be audible.
No. The AMORNO is Bluetooth-only with no headphone jack, so it can't plug into a seatback screen. That's exactly the job the AirFly Pro 2 was built for.
Since this page doesn't quote prices, check the current price on Amazon for both — they sit in very different product categories, so the comparison isn't apples to apples. Buy the AMORNO if you need headphones; buy the AirFly Pro 2 if you need an adapter.
