Its strongest benefit is how little friction it adds to a flight. Plug the adapter into the seatback entertainment jack, put the headphones into pairing mode, and establish the wireless connection. Built-in buttons provide volume control, while more than 20 hours of playback should cover a long-haul itinerary. The included USB-C cable also permits use while charging, which is particularly reassuring when recharging is inconvenient at the gate.
The AirFly SE does not offer the dual-listener capability found on several competitors, so it is less suitable for sharing a movie with a companion. Its listed function centers on transmitting audio from a 3.5mm jack rather than operating as a general-purpose receiver. Those restrictions actually make the product easier to understand for travelers who only need to solve the familiar airplane headphone problem.
This is the strongest general recommendation for a solo traveler who values portability, uncomplicated operation, and dependable battery life. It also suits anyone who wants a device that can remain connected during a charging session. Travelers who regularly listen with a partner should look toward the Relay or AirFly Pro 2, while those wanting broader home and travel functions may prefer a two-in-one model.
Built for Long Travel Days
More than 20 hours of battery life covers long listening sessions, and the ability to operate while charging helps prevent an inactive adapter from interrupting an in-flight movie.
Small and Simple to Carry
The lightweight enclosure can remain in a personal item or tech pouch without adding bulk, while the physical volume buttons make daily operation uncomplicated.

We may earn a commission when you buy through this link, at no additional cost to you.
The Relay addresses one of the most common frustrations with seatback entertainment. A solo traveler can connect one pair of headphones, while a couple or traveling family can connect two sets at the same time. Pairing is described as a three-step process: plug the Relay into the 3.5mm jack, place the headphones in pairing mode, and complete the connection. A dual-prong airplane adapter is included for the appropriate seatback connection.
Its primary limitation is that it is a transmitter only. It cannot receive Bluetooth audio, lacks a microphone, and is not intended for phone calls, televisions, hearing aids, musical instruments, or other receiving functions. The specification is unusually explicit about this, which is helpful because buyers can avoid expecting a general-purpose audio adapter.
The Relay is an excellent recommendation for two people who want to share an in-flight movie, podcast, or music program from one screen. It is also attractive for solo travel due to its 25-hour maximum playback, onboard volume controls, and battery indicator. Users who need a microphone or receiver mode should choose a two-in-one model instead.
One Screen, Two Headphone Sets
Simultaneous dual pairing is the Relay's defining advantage, allowing two travelers to use separate wireless headphones while listening to the same entertainment source.
Codec Support for Compatible Gear
aptX Adaptive and aptX HD can improve wireless audio behavior when paired with compatible equipment, although actual results depend on the connected headphones.

3. UGREEN 2-in-1 Adapter – Best Versatile Two-in-One Design
UGREEN 2-in-1 Adapter
Bluetooth 6.0 technology
18-hour RX battery
16-hour TX battery
10-meter transmission range
The UGREEN Airplane Bluetooth 6.0 Transmitter Receiver is a two-in-one adapter that can work with an airplane, television, car stereo, or another 3.5mm source. It carries a 4.1 rating and offers more functions than a basic transmitter, including transmitter mode, receiver mode, a built-in microphone, and a stated 10-meter transmission distance.
Pros
- Transmitter and receiver modes
- Built-in microphone
- Broad device compatibility
- Compact travel format
- Ten-meter stated range
Cons
- Several AirPods models excluded
- iPhone reconnect requires manual action
We may earn a commission when you buy through this link, at no additional cost to you.
In transmitter mode, the adapter sends audio from a wired source to Bluetooth headphones. In receiver mode, it can add Bluetooth reception to a non-Bluetooth stereo system, allowing a phone or computer to send audio to it. This makes the device useful beyond the airplane, particularly for travelers who want one compact unit for flights, hotel exercise equipment, a car audio system, or a television.
There are important compatibility caveats. The listing specifically says the adapter is incompatible with AirPods Pro 2, AirPods Pro 3, AirPods 4, and AirPods 4 ANC. It also notes that iPhone users may have to reconnect manually rather than have the adapter reconnect automatically. These restrictions should be checked before buying, particularly for travelers who rely on a specific recent AirPods model.
The UGREEN is worth considering for buyers who value flexibility more than dedicated two-person airplane sharing. Its built-in microphone, dual operating modes, and broad source compatibility give it more utility than a transmitter-only device. However, the 4.1 rating is slightly lower than the leaders, and its AirPods exclusions mean it is not the safest universal recommendation.
More Useful Beyond the Airplane
Receiver mode turns the adapter into a way to add Bluetooth to older speakers or a wired car system, expanding its usefulness beyond aircraft entertainment.
Check Your Headphone Model
Several named AirPods generations are excluded, so travelers should confirm their exact model before purchase rather than relying on the broad AirPods label.

We may earn a commission when you buy through this link, at no additional cost to you.
Its travel readiness comes from a combination of quick setup and battery management. Automatic pairing begins at power-on, system memory supports reconnection with many headphone brands, and a bundled dual-prong airplane-style adapter simplifies access to compatible seatback connections. More than 20 hours of playback, USB-C recharging in about an hour and a half, and continued use while charging cover long itinerates.
The wide source support is attractive, but so are the boundaries. The device is not compatible with Bluetooth hearing aids, musical instruments, live music, karaoke, or devices using 2.4GHz synchronization. Those exclusions are reasonable for a portable entertainment adapter, but it should not be treated as professional audio equipment. The integrated microphone also distinguishes it from transmitter-only products.
This is a strong pick for a traveler who wants more than a minimal airplane connector and who may also use older AUX or RCA sources. Its dual-listener support is especially useful for couples, while receiver mode expands its role at home and in a vehicle. Buyers seeking a simple dedicated transmitter may find the Avantree Relay easier to operate.
Fast Reconnection for Busy Itineraries
Power-on pairing and system memory reduce setup time, which is helpful when boarding, changing gates, or moving between different travel entertainment sources.
Shared Audio Without Extra Cables
Transmitter mode supports two simultaneous headphone connections, allowing two travelers to hear the same airplane program on separate headsets.

For airplane use, the transmitter mode handles the familiar seatback entertainment connection. Dedicated pairing buttons simplify adding a second set of wireless headphones, making the adapter suitable for sharing a movie, music, or video game. Receiver mode broadens its role by sending audio from a phone to a car, boat, or other 3.5mm system without requiring a Bluetooth source.
Its latency-related specifications are particularly relevant for movies and games. The listing emphasizes low-latency operation, although the best result depends on the capabilities of the paired headphones. The device also uses physical quick-access controls for sound adjustment and muting. A display is deliberately omitted, which helps preserve the compact size and supports the long battery life.
The AirFly Pro 2 is the premium recommendation for travelers who want airplane performance and broader utility in one package. It is a better fit than a transmitter-only model for someone who also expects to connect a phone to an older stereo. The trade-off is a more advanced feature set and the need to select the appropriate mode and codec for the connected equipment.
One Adapter for Several Systems
Transmitter mode serves airplane screens and other wired entertainment, while receiver mode adds convenient wireless phone audio to legacy car, boat, and stereo connections.
Designed for Movie Watching
aptX HD Adaptive support and low-latency operation can improve synchronization when used with compatible headphones, particularly for video and games.

We may earn a commission when you buy through this link, at no additional cost to you.
The transmitter side is the central reason to consider it for flying. Audio from an airplane screen, gym television, or gaming console can be sent to AirPods, Sony headphones, or other compatible Bluetooth equipment. Dual pairing lets a second set of headphones join through dedicated controls. Physical buttons provide quick access to volume and mute functions without navigating a menu.
Its versatility comes from the flip between transmitter and receiver roles. In receiver mode, a phone can transmit music to a car or boat AUX system. The product does not rely on a display, allowing the manufacturer to keep the body compact and extend battery performance. aptX HD Adaptive support is useful for compatible devices, but it does not guarantee low latency when the headphones lack the necessary support.
This listing is ideal for a traveler who places particular value on the AirFly Pro 2 feature set and wants two-person listening. It may also appeal to buyers who want one adapter for aircraft, gym, gaming console, car, and boat use. The principal consideration is whether its advanced feature set justifies a premium-tier purchase compared with the standard Pro 2.
A Polished Travel Companion
The compact enclosure and lack of a display make the Deluxe straightforward to pack, while the long battery life supports extended use without frequent charging.
Flexible for Two
Two independent headphone connections make it easy to share entertainment without asking a travel companion to use the same earbuds or an awkward shared wired headset.

We may earn a commission when you buy through this link, at no additional cost to you.
The dual-headphone capability separates the Relay from ordinary single-listener transmitters. Both travelers can use their own preferred earbuds without sharing a single set or relying on a wired splitter. The included dual-prong airplane adapter addresses the common two-prong seatback connector, while onboard volume controls and a battery indicator help manage the device without guessing.
This adapter is not a general two-in-one device. It sends audio from a 3.5mm source to Bluetooth headphones but does not receive Bluetooth audio. It also has no microphone and is not designed for calls, televisions, hearing aids, or musical instruments. For a traveler focused strictly on airplane entertainment, those limits make the product predictable rather than problematic.
The Relay is an excellent recommendation for couples or family members who regularly fly with separate wireless earbuds. It also works for a solo traveler who wants generous battery life and reliable physical controls. Those who want a microphone, home receiver functionality, or broader compatibility should look at the UGREEN, SOOMFON, or AirFly Pro 2 alternatives.
A Purpose-Built Travel Process
The adapter plugs into the entertainment jack, headphones enter pairing mode, and the wireless connection completes in three clearly defined steps.
Practical Status Controls
A clear battery indicator and onboard volume controls reduce uncertainty during boarding and make the device easier to operate in a dim cabin.

We may earn a commission when you buy through this link, at no additional cost to you.
Its appeal lies in the balance of simplicity and capability. Travelers connect the Relay to the appropriate 3.5mm seatback connection, put both headphone sets into pairing mode, and finish the wireless setup. Once connected, each person can use separate earbuds or headphones with independent comfort and sound preferences. Physical onboard controls allow easy volume management during the flight.
The product's transmitter-only design is both its main limitation and the reason it remains focused. It cannot receive audio from a phone, it has no microphone, and the listing excludes uses such as TVs, hearing aids, and musical instruments. Travelers who only need to move airplane entertainment to wireless headphones will find that boundary easy to navigate.
This Relay listing is a strong choice for couples, friends, or family members traveling with the same entertainment source. It is particularly convenient when neither person wants to share earbuds. For a solo passenger, it still provides useful battery life and clear controls, but buyers seeking broader functionality should consider one of the dual-mode alternatives.
Personal Listening for Two
Separate wireless headsets eliminate the need to share a single pair of earbuds, improving comfort during long movies and allowing each traveler to control personal volume preferences.
Long-Haul Battery Coverage
The stated 25-hour maximum provides useful endurance for long routes, although actual runtime varies with active connections and usage.

23-hour TX battery
17-hour RX battery
LCD status display
The SOOMFON aptX-LL Bluetooth 5.3 Transmitter Receiver is built around low-latency wireless audio and carries a 4.4 rating. Its headline capability is aptX Low Latency support with latency as low as 40 milliseconds. That focus makes it especially interesting for in-flight movies, television, and games where lip synchronization matters.
Pros
- Very low stated latency
- Display shows device status
- Supports two headphone sets
- Both transmitter and receiver modes
- Fast USB-C charging
Cons
- No microphone for calls
- No individual dual-mode volume control
We may earn a commission when you buy through this link, at no additional cost to you.
The adapter can transmit audio from a 3.5mm source to two sets of wireless headphones or speakers and can receive Bluetooth audio from two phones in receiver mode. A built-in LCD displays pairing status, connected devices, and the current operating mode. For frequent travelers who switch between transmitter and receiver roles, that visibility can be more useful than a compact unit with minimal indicators.
It is important that the paired headphones also support aptX Low Latency to obtain the best latency performance. The device has no microphone, does not support individual volume adjustment in dual-connection mode, cannot pair with devices requiring a PIN, and does not support Dolby audio. In receiver mode, only one of two connected devices can play audio at a time.
The SOOMFON is a strong recommendation for travelers who watch a lot of video and want clearer audio-to-picture synchronization. Its LCD also makes setup and troubleshooting more transparent. Those who need phone calls, advanced multi-device audio, or Dolby support should examine those requirements carefully before buying.
Video and Audio Stay Closer
The advertised 40-millisecond aptX LL performance can reduce lip-sync delay when the connected headphones support the same low-latency technology.
Visible Setup and Connection Status
The LCD helps users identify the operating mode, pairing state, and connected devices without repeatedly reconnecting or guessing which mode is active.

Simple three-step pairing
3.5mm airplane input
Another Avantree Relay listing offers the same focused approach to airplane audio: a dedicated 3.5mm transmitter that can connect two pairs of Bluetooth headphones or earbuds. It holds a 4.3 rating and emphasizes a simple three-step setup, up to 25 hours of playback, and support for aptX Adaptive and aptX HD with compatible headsets.
Pros
- Straightforward airplane setup
- Two headphone connections
- Long battery runtime
- aptX Adaptive and HD
- Includes dual-prong adapter
Cons
- No Bluetooth receiver function
- Unavailable for microphone calls
We may earn a commission when you buy through this link, at no additional cost to you.
Its appeal to travelers is immediate. Plug the Relay into the seatback entertainment connection, place the wireless headphones into pairing mode, and complete the connection. A dual-prong airplane adapter is included. Two listeners can then use separate headsets from the same source, which is especially convenient on family trips or long flights with a companion.
Buyers should note that the adapter has no microphone and cannot receive Bluetooth audio. It is also not intended for televisions, hearing aids, musical instruments, or other receiving applications. The explicit transmitter-only design reduces setup ambiguity, but it does make the Relay less useful outside aircraft than a two-in-one adapter with receiver mode.
This listing is well suited to travelers who know they need a dedicated solution for sharing airplane entertainment. The long battery life, onboard volume controls, clear battery indicator, and dual-headroom pairing make it practical for both solo and shared listening. Buyers who want greater flexibility should compare it with the AirFly Pro 2 or SOOMFON.
Minimal Learning Curve
The three-step process uses familiar airplane connections and standard headphone pairing, reducing setup time for first-time adapter users.
Two Sets, One Entertainment Source
Dual pairing is the defining feature for travel companions who want separate earbuds or headphones without introducing another wired connection.

Buying Guide – How to Choose the Best Bluetooth Headphone Adapters for Flying
The right travel adapter depends on how you listen, whether you travel alone, which headphones you own, and how much versatility you need beyond the airplane. These factors help narrow the field before purchase.
Airplane Jack Compatibility
Most airplane seatback entertainment systems use a 3.5mm connection, but the physical plug arrangement can differ. A single-prong adapter fits a conventional socket, while a dual-prong airplane adapter is designed for systems with two small sections. The Relay listings include a dual-prong accessory, and the 2026 Upgrade Pro Adapter also includes a similar travel connector. Before buying, check the socket on your seatback and the type of connector you expect to use.
Choose an adapter with connections that match your airline's entertainment hardware and avoid relying on an unlisted universal connector.
Transmitter Versus Receiver
A transmitter sends audio from a wired source to Bluetooth headphones, which is the primary function needed for airplane entertainment. A receiver does the opposite, accepting Bluetooth audio and sending it to a wired speaker, stereo, or car system. The Avantree Relay is transmitter only, while the UGREEN, 2026 Upgrade Pro, AirFly Pro 2, and SOOMFON offer both modes. Travelers who only use headphones on flights may prefer the simpler dedicated design.
For frequent flyers, transmitter mode is essential; for multi-purpose travel, receiver mode adds useful flexibility.
Number of Headphones
Consider whether you listen alone or share a flight with a companion. The Relay supports two simultaneous headphone connections, as do the AirFly Pro 2, AirFly Pro 2 Deluxe, 2026 Upgrade Pro Adapter, and SOOMFON. The AirFly SE is centered on a single wireless connection. Dual pairing gives each traveler separate earbuds or headphones, but some multi-device adapters do not support individual volume adjustment in that mode.
Select dual pairing if sharing is important, and verify whether separate volume control is also necessary.
Battery Life and Charging
Long flights make battery endurance a practical concern. The listed maximum runtimes range from 16 to 18 hours for some transmitter or receiver modes, 20-plus hours for the AirFly SE and 2026 Upgrade Pro Adapter, approximately 23 hours in transmitter mode for the SOOMFON, 25 hours for the Relay, and more than 25 hours for the AirFly Pro 2 models. Actual runtime depends on mode, connection count, and use. USB-C recharging is convenient, and the AirFly SE and 2026 Upgrade Pro can operate while charging.
Compare runtime in the mode you will actually use, not just the largest figure stated for a different mode.
Latency and Codec Support
Wireless latency can create a visible delay between dialogue and on-screen movement. The SOOMFON supports aptX Low Latency with latency as low as 40 milliseconds, while the Relay and AirFly Pro 2 models support advanced aptX options. The SOOMFON and Relay listing specify aptX Adaptive and aptX HD support, and the AirFly Pro 2 models advertise aptX HD Adaptive. Codec benefits depend on compatible headphones and cannot be guaranteed by the adapter alone.
For heavy movie viewing or gaming, choose low-latency features and confirm that the paired headphones support them.
Headphone and AirPods Compatibility
Bluetooth adapters generally work best with headphones designed for wireless audio, but specific product exclusions still matter. The UGREEN listing is incompatible with AirPods Pro 2, AirPods Pro 3, AirPods 4, and AirPods 4 ANC. The 2026 Upgrade Pro Adapter says it cannot be used with Bluetooth hearing aids, musical instruments, karaoke, live music, or 2.4GHz-synchronization devices. The SOOMFON cannot pair with devices that require a PIN and does not support Dolby audio.
Check the exact model of your headphones and the features of your entertainment source before ordering.
Calls and Microphone Needs
An in-flight entertainment adapter does not automatically function as a phone-call accessory. The Relay listings have no microphone and are not intended for calls. The UGREEN and 2026 Upgrade Pro include microphones, while the AirFly Pro 2 products focus on sending entertainment audio. The SOOMFON also lacks a microphone and explicitly excludes phone-call use. If you expect to use a headset for calls, confirm that microphone functionality exists rather than assuming every Bluetooth adapter supports it.
Separate call functionality from entertainment streaming and verify each capability separately.
Portability and Setup Visibility
A travel adapter should be easy to find and operate in a dim cabin. Compact bodies such as the AirFly SE fit neatly into a tech pouch, while physical buttons provide quick volume access. The SOOMFON takes a different approach with an LCD that displays mode, pairing status, and connected devices. The Relay, UGREEN, and AirFly Pro 2 offer simpler controls. Choose minimalism for a smaller everyday carry or a display when troubleshooting and mode visibility are your priorities.
Balance pocketability against the visibility and controls you are most likely to need while traveling.
How to Use and Care for Your Bluetooth Headphone Adapters for Flying
Before departure, fully charge the adapter and confirm that it is in transmitter mode. Connect it to the airplane entertainment jack using the appropriate single- or dual-prong connector, then put your wireless headphones or earbuds into pairing mode. Select the adapter on the headphones if necessary, check that audio is playing, and adjust the volume using the onboard controls.
For a dual-listener setup, pair the second set of headphones after the first connection is stable. Confirm both listeners hear the same program before the movie begins. When using a low-latency mode, verify that the connected headphones support the corresponding aptX feature. If audio is absent, test the wired source directly and check the selected transmitter or receiver mode.
Carry a short USB-C charging cable and keep the adapter in an easy-to-reach pocket rather than loose in a larger bag. After the flight, switch it off and reconnect it to the charger. Clean the 3.5mm connector gently, avoid moisture, and follow the manufacturer’s battery guidance. Repeatedly pairing should not require factory resets unless the manufacturer specifically instructs one.
Frequently Asked Questions
Can I use my AirPods with an airplane entertainment system?
Yes, if your AirPods model is compatible with the chosen adapter. You connect a Bluetooth transmitter to the airplane's 3.5mm jack and then pair your AirPods with it. However, the UGREEN listing specifically excludes AirPods Pro 2, AirPods Pro 3, AirPods 4, and AirPods 4 ANC, so check your exact generation before purchasing.
Do I need a dual-prong airplane adapter?
It depends on the entertainment socket on your seatback. A dual-prong connector is designed for the common two-section airplane jack, while some sockets accept a standard single plug. The Relay and 2026 Upgrade Pro listings include dual-prong adapters, which adds useful travel flexibility.
Can I connect two sets of wireless headphones?
Several adapters support simultaneous dual headphone connections, including the Relay, AirFly Pro 2, AirFly Pro 2 Deluxe, 2026 Upgrade Pro Adapter, and SOOMFON. This is useful for sharing an in-flight movie. Note that some models do not allow individual volume adjustment for both connected sets.
What is the difference between transmitter and receiver modes?
Transmitter mode takes audio from a wired source such as an airplane entertainment system and sends it to Bluetooth headphones. Receiver mode receives audio from a phone or computer and sends it to a wired stereo or speaker. A transmitter-only adapter is sufficient for many flights, while a two-in-one model is more versatile.
Will a Bluetooth adapter fix audio delay during movies?
It may help if the adapter and headphones both support a low-latency feature. The SOOMFON supports aptX Low Latency with latency stated as low as 40 milliseconds, and other featured adapters support advanced aptX options. Without compatible support on both devices, some delay can remain.
Can I use these adapters for phone calls?
Not every model supports calls. The Relay has no microphone and is not intended for phone calls. The UGREEN and 2026 Upgrade Pro include built-in microphones, while the SOOMFON has no microphone. Check the product specifications and intended mode before relying on an adapter for conversations.
How long should I charge an airplane Bluetooth adapter before traveling?
A full charge is the safest starting point, especially for a long flight. Listed battery runtimes vary by model and mode, with maximum figures ranging from 16 to more than 25 hours. Bring a USB-C charging cable if your route may exceed the available runtime or if you plan to use the adapter while charging.
Does Bluetooth 6.0 guarantee better airplane audio?
A newer Bluetooth version can contribute to faster pairing and more stable transmission, but audio quality also depends on the implementation, source, codecs, and connected headphones. The UGREEN and 2026 Upgrade Pro advertise Bluetooth 6.0, while the AirFly Pro 2 models use Bluetooth 5.3. Compare supported features rather than the version number alone.
Final Thoughts on Choosing the Best Bluetooth Headphone Adapters for Flying
The Twelve South AirFly SE is the strongest overall recommendation for a solo traveler because it combines a compact body, more than 20 hours of battery life, and use-while-charging convenience. The Avantree Relay stands out when two people want separate wireless headphones from one seatback screen, while the AirFly Pro 2 is the premium all-around choice for travelers who also value receiver mode.
Prioritize the features your trip actually requires. Verify the airplane jack type, confirm that your headphones are compatible, and decide whether you need one or two listeners. Battery runtime, low-latency codecs, a microphone, and a status display can distinguish otherwise similar adapters, so the most advanced model is not automatically the most convenient one for every passenger.
Before ordering, recheck the current product listing and included accessories because model availability, compatibility details, and deal terms can change. With the correct connector and headphone support confirmed, a good adapter can make in-flight entertainment feel considerably more comfortable and personal.
