How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a single dedicated airline adapter that turns a two-prong seat jack into a normal 3.5mm socket for almost any headphone you already own, choose Saipomor WH1000XM5; if you need a two-pack of lightweight dual 3.5mm adapters so you always have a spare in your bag, choose OiDiPi Dual 3.5mm.
• Saipomor WH1000XM5 – biggest strength: It converts a dual-prong airline jack into a standard 3.5mm stereo jack with no setup, no software and a one-year warranty, and it explicitly lists Sony WH-1000XM4/XM3/XM2, MDR-1000X and EX750NA as compatible headphones.
• Saipomor WH1000XM5 – biggest trade-off: You get exactly one adapter in the package, so if it goes missing between flights you are back to square one.
• OiDiPi Dual 3.5mm – biggest strength: It ships as a two-pack (one black, one white) of gold-plated dual 3.5mm male to 3.5mm female adapters, so you have an instant backup and can leave one in a carry-on permanently.
• OiDiPi Dual 3.5mm – biggest trade-off: It is the bulkier, heavier option on paper, and the two units are the only thing in the box — no single-adapter fallback is included.
• Who each pick is for: Saipomor is for the traveler who owns one pair of wired headphones and wants one simple, warrantied adapter; OiDiPi is for the traveler who wants redundancy, a spare for a companion, or a second adapter for a different bag.
The Saipomor WH1000XM5 is a purpose-built airline audio adapter. Its entire job is to take the two-prong socket you find on many in-flight entertainment systems and turn it into the single 3.5mm stereo jack your headphones expect. The brand lists compatibility with any headphones or earphones that use a 3.5mm plug, and it names specific Sony models — WH-1000XM4, WH-1000XM3, WH-1000XM2, MDR-1000X and EX750NA — along with Monster, Bose, Beats and Apple EarPods. It also converts the two mono channels from the seat jack into one stereo signal, which is exactly what you want when you are watching a movie on a long-haul flight.
The design is deliberately minimal. The connector is gold-plated, which the brand frames as durability and corrosion resistance, and the unit is described as lightweight and pocketable. There is no app, no pairing, no setup step: you plug the adapter into the armrest port, plug your headphones into the adapter, and the in-flight entertainment plays through your own cans. For someone who already travels with a good pair of wired headphones, that is the whole appeal — you keep the comfort and sound isolation you already like instead of using the airline's disposable earbuds. Saipomor also backs it with a one-year warranty, which is a meaningful detail for a part that lives in a bag and gets plugged and unplugged constantly.
OiDiPi Dual 3.5mm: Who It's For
The OiDiPi Dual 3.5mm does the same core job — dual-prong airline socket in, standard 3.5mm stereo jack out — but it is packaged and positioned differently. You get two adapters, one black and one white, each a dual 3.5mm male to 3.5mm female connector with gold plating. OiDiPi describes gold plating as corrosion-resistant and as a way to keep sound transmission clean, and the brand highlights a one-piece forming construction. The pitch is straightforward: plug the adapter into the seat's audio jack, plug your own headphones in, and watch the movie with the headphones you actually like.
The two-pack is the real story here. In practice that means one adapter can live permanently in your carry-on while the other stays in your daypack, or you can hand one to whoever is sitting next to you. The color difference makes them easy to tell apart, which sounds trivial until you have two identical black adapters rolling around a seat pocket. OiDiPi also states compatibility with most devices that use a standard dual or single 3.5mm output, so the adapters are not strictly a one-trick airplane item — they can serve as a general 3.5mm connector in other setups.
The trade-offs are honest ones. On paper this is the heavier option: the item weight is listed at 16.2 g and the dimensions at roughly 0.98 x 0.4 x 1.38 inches, so it is more of a small accessory than a near-weightless dongle. It is also sold purely as the two adapters — no additional single-jack adapter is bundled, so if you specifically needed one adapter plus a different style of connector, this box does not cover that. And like the Saipomor, it is a wired accessory: it exists to route an analog signal into headphones with a 3.5mm plug.
Who should buy it? Travelers who want a spare, people who fly with someone else and want two adapters without buying twice, and anyone who prefers a slightly more substantial-feeling connector. Who should skip it? If you want the smallest possible single adapter and you never lose things, the extra bulk and the second unit may simply be unnecessary.
Side-by-Side: Which Should You Choose?
• Best for the Sony WH-1000XM4/XM3/XM2 owner → Saipomor WH1000XM5. It names those models directly in its compatibility list, so there is no guesswork about fit.
• Best for a travel companion or family → OiDiPi Dual 3.5mm. Two units, two colors, two people — no need to share one adapter on a long flight.
• Best for minimal bulk → Saipomor WH1000XM5. Listed at 0.01 kg, it is the lighter, smaller single-unit option for a pocket or a small pouch.
• Best for a warranty on a single part → Saipomor WH1000XM5. It carries a one-year warranty, which matters for an accessory that gets plugged in and out constantly.
• Best for a general-purpose 3.5mm connector on the road → OiDiPi Dual 3.5mm. The brand states compatibility with devices using standard dual or single 3.5mm outputs, not just airplane jacks.
• Best for travelers who like matching or labeling gear → OiDiPi Dual 3.5mm. Black and white units are easy to assign to different bags or people.
• Best for anyone flying with wired headphones and nothing else → either works. Both convert a dual-prong airline socket to a standard 3.5mm stereo jack with no software or setup.
In my opinion, the OiDiPi Dual 3.5mm is the smarter buy for most people, purely because two adapters solve the single most common failure mode of this category — the adapter that vanishes into a seat pocket or a hotel room. The Saipomor WH1000XM5 is a solid, focused single adapter with a clean compatibility list for Sony owners and a one-year warranty, and if you want exactly one well-made unit, I would point you to it without hesitation. But for airplane use specifically, redundancy wins. I would rather have a spare in my bag than a slightly lighter single adapter I have to remember to pack — and if you want to compare what each costs right now, use the price button on this page to check the latest price on Amazon before you decide.
what headphones for airplane
Any wired headphones or earphones with a standard 3.5mm plug will work with either adapter — both Saipomor and OiDiPi list broad 3.5mm headphone compatibility, and Saipomor specifically names Sony WH-1000XM4, WH-1000XM3, WH-1000XM2, MDR-1000X and EX750NA. The adapter's job is converting the plane's dual-prong socket into the single jack your headphones already use.
what is the best headphones for airplanes
That depends on what you already own rather than on the adapter. Both products are converters, not headphones: they let you use your own 3.5mm headphones with in-flight entertainment. Pick Saipomor WH1000XM5 if you want one lightweight adapter with a one-year warranty, and OiDiPi Dual 3.5mm if you want a two-pack so you always have a spare.
what earphones for airplane
Earphones with a 3.5mm plug work with both adapters — Saipomor explicitly mentions Apple EarPods alongside over-ear brands, and OiDiPi says its adapter suits all headphones, headsets and Bluetooth adapters with 3.5mm connectors. If your earphones are wireless-only with no wired option, neither adapter can help you.
what kind of headphones for airplane
You want wired headphones with a 3.5mm connector, because that is the plug both adapters output. Over-ear models tend to isolate engine noise better than small earbuds, which is why a dual-prong-to-3.5mm adapter paired with your own closed-back headphones is the common setup. Just confirm your headphones have a 3.5mm jack before you fly.
