If you want a tiny, no-charging, plug-and-play fix for in-flight entertainment jacks, choose Asobilor Dual 3.5mm; if you need to cut the cord entirely and run your own Bluetooth headphones or earbuds on a plane, choose LEZIRLOA Airplane.
• Asobilor Dual 3.5mm — biggest strength: a foldable plug that switches between single and dual 3.5mm jacks, so it fits the vast majority of airline seat audio sockets without guesswork.
• Asobilor Dual 3.5mm — biggest trade-off: it is a passive adapter, not a wireless device. It does nothing for you unless you already own wired headphones with a 3.5mm cable.
• LEZIRLOA Airplane — biggest strength: it is a 2-in-1 Bluetooth transmitter/receiver with an LCD screen, dual headphone pairing and a claimed 20H+ playtime on a rechargeable battery.
• LEZIRLOA Airplane — biggest trade-off: it is a battery-powered electronic device, so it needs charging (about 1 hour per the specs) and adds a small gadget to keep track of in your bag.
• Who each pick is for: Asobilor for wired-headphone travelers who want zero setup and zero charging; LEZIRLOA for travelers who want to use Bluetooth headphones or earbuds on a plane or TV.
The Asobilor Dual 3.5mm is about as simple as airplane audio gets. You plug the 3.5mm female end into your headphone cable, then plug the male end into the seat's aviation jack. That's it. No pairing, no battery, no charging cable, no menu. It weighs 10 grams and measures 0.2 x 1.6 x 0.5 inches, so it disappears into a pocket or a headphones case.
The feature that actually matters for flying is the foldable plug. Airline seat audio jacks are inconsistent — some are a single 3.5mm socket, others use the twin-prong layout. This adapter folds between single and double plug configurations, so you don't have to figure out which airline uses which before you board. In my opinion, that flexibility is the whole reason to buy it.
The other spec worth noting is the gold-plated tip. Asobilor states it improves signal input, reduces external noise and extends service life. Gold plating on a connector is a real, standard choice for corrosion resistance and a more stable contact, and a stable contact is what keeps in-flight audio from crackling. Don't read that as "audiophile sound quality" — it's a connector, not a DAC. It passes the seat's audio through to your headphones.
Who should buy it: anyone flying with wired headphones, especially Bose owners. The compatibility list covers QC2, QC3, QC15, QC20, QC25, QC35, QC35ii, NC700, SoundLink, SoundLinkII, AE2, AE2i and AE2W, plus most devices with standard single or dual 3.5mm jacks. It also carries a 1-year warranty.
LEZIRLOA Airplane: Who It's For
The LEZIRLOA Airplane is a different category of product. It's a 2-in-1 Bluetooth transmitter and receiver built for flights and TVs, and its job is to bridge the gap between a wired audio source (like a seatback entertainment jack) and your wireless headphones. In transmitter mode it takes the airplane's 3.5mm AUX output and broadcasts it over Bluetooth. In receiver mode it does the reverse — it takes a Bluetooth signal and outputs through 3.5mm AUX stereo.
The standout spec is dual headphone pairing. Two people can connect their own Bluetooth headphones to the same seatback screen, which is genuinely useful on a long flight when you and a travel companion both want to watch the same movie without sharing a splitter cable and a single pair of earbuds.
It also has a visual LCD screen, which is more helpful than it sounds. On a plane you're often fumbling in low light, and a screen that shows connection and mode status beats guessing from a blinking LED. Controls are push-button with volume control, so you're not relying on your phone for everything.
Battery-wise, the specs list a 3.7V, 1.11Wh lithium-polymer cell, roughly 1 hour to charge, and 20H+ claimed playtime. For a transatlantic flight that's comfortably in range, though I'd treat any "20H+" figure as a manufacturer claim rather than a guarantee — real numbers depend on volume and which mode you're using.
Two things to weigh honestly. First, it's 19.87 grams and 1.5"L x 0.5"W x 4.5"H — noticeably bulkier than a passive adapter, and something you have to remember to pack and charge. Second, it's a Bluetooth device, so you're adding a wireless link where a cable would do. For some people that's the entire point; for others it's an extra failure point. It carries a 12-month warranty.
Who should buy it: Bluetooth-headphone owners, couples or families sharing a screen, and anyone who also wants a transmitter/receiver for a TV at home. Who should skip it: minimalists who just want their wired headphones to work on the plane.
• Best for wired headphones → Asobilor Dual 3.5mm. No battery, no pairing, no setup.
• Best for Bluetooth headphones on a plane → LEZIRLOA Airplane. It's the only one of the two that speaks Bluetooth.
• Best for two people, one screen → LEZIRLOA Airplane. Dual headphone pairing is the deciding feature here.
• Best for single vs. dual airline jacks → Asobilor Dual 3.5mm. The foldable plug handles both layouts.
• Best for zero maintenance → Asobilor Dual 3.5mm. Nothing to charge, ever.
• Best for battery life → LEZIRLOA Airplane. 20H+ claimed playtime versus no battery at all on the adapter.
• Best for packing light → Asobilor Dual 3.5mm. 10 grams and 0.2 x 1.6 x 0.5 inches.
• Best for TV use at home too → LEZIRLOA Airplane. The receiver mode works beyond the plane.
In my opinion, the choice comes down to one question: are your headphones wired or wireless? If they're wired — especially Bose — I'd buy the Asobilor Dual 3.5mm. It's the lowest-friction way to make a seatback jack work, and the foldable plug means I never have to think about the airline's jack layout. If your headphones are Bluetooth, I'd buy the LEZIRLOA Airplane instead, because the Asobilor simply can't do that job, and the dual pairing plus LCD screen make it the more capable travel gadget. Check the current price on Amazon for both before you decide.
what headphones for airplane
Any wired headphones with a 3.5mm cable work with the Asobilor Dual 3.5mm adapter, and the LEZIRLOA Airplane lets you use Bluetooth headphones instead. If you want the simplest option, bring wired headphones and the adapter; if you want wireless freedom, bring the Bluetooth transmitter.

There's no single answer in these specs — it depends on your headphones, not the adapter. If yours are wired, the Asobilor adapter is the cleaner fit. If yours are Bluetooth, the LEZIRLOA transmitter/receiver is the one that makes them usable with a seatback screen.

Earbuds with a 3.5mm plug work directly with the Asobilor adapter. Bluetooth earbuds need the LEZIRLOA Airplane in transmitter mode, which supports dual headphone pairing so two sets of earbuds can share one screen.

Wired over-ear or in-ear headphones with a 3.5mm jack pair with the Asobilor Dual 3.5mm and its foldable single/dual plug. Bluetooth headphones need the LEZIRLOA Airplane, which adds a battery, an LCD screen and roughly 20H+ claimed playtime.
