Transmitter mode sends audio from an airplane seatback, gym television, gaming console, or another 3.5 mm source to wireless headphones. Receiver mode reverses that relationship, allowing a phone to send audio to a wired car or boat system. Dual pairing lets two sets of Bluetooth headphones listen together, while dedicated pairing buttons simplify adding the second set.
The adapter lists aptX HD Adaptive support for compatible devices and emphasizes stable, low-latency audio for films and games. Its stated playback time exceeds 25 hours, which should cover many long-haul flights, while quick-access buttons provide convenient sound and mute control. One qualification is that the richest codec behavior depends on the capabilities of the paired headphones.
This is the most well-rounded recommendation for frequent flyers because it handles single listening, shared listening, and non-flight use without requiring a second device. Travelers who only need a simple transmitter can save money, but those who want a compact multi-purpose travel tool will find the wider feature set worthwhile.
Useful Beyond the Airplane
Receiver mode gives the adapter value after a trip. It can connect a phone to a car, boat, or other wired audio system, while transmitter mode also works with gym equipment, televisions, and consoles. That versatility makes it easier to justify carrying on frequent journeys.
Shared Listening for Two Travelers
Dual pairing is especially practical when two people are watching the same movie. Instead of sharing one pair of earbuds or using a splitter, each traveler can use a separate compatible pair of wireless headphones.

We may earn a commission when you buy through this link, at no additional cost to you.
The stated three-step process is refreshingly simple. Connect the Relay to the airplane entertainment jack, place the first pair of headphones in pairing mode, and complete the connection before adding the second pair. A dual-prong airplane adapter is included, which helps accommodate seatback connectors with dual output.
Qualcomm audio technology is paired with aptX Adaptive and aptX HD support for compatible headphones. The adapter offers up to 25 hours of playback, onboard volume controls, and a clear battery indicator. These details make it easy to monitor the device during a long flight without opening a companion app.
The important limitation is that Relay is transmitter-only. It has no microphone and is not intended for phone calls, television reception, hearing aids, musical instruments, or receiving audio from a phone. For a traveler whose sole goal is sharing in-flight entertainment, that narrow scope is an advantage rather than a drawback.
Designed for Two Listeners
The Relay's defining feature is simultaneous connection for two pairs of Bluetooth headphones or earbuds. That makes it a straightforward solution for travelers who regularly watch movies together and do not need broader home or office functions.
A Clear Three-Step Setup
Physical controls, a visible battery indicator, and a simple connection sequence reduce the chance of fumbling with settings after boarding. The included dual-prong adapter also reduces the chance that an unfamiliar seatback connection will prevent setup.

We may earn a commission when you buy through this link, at no additional cost to you.
In transmitter mode, it connects a television, airplane entertainment system, or another 3.5 mm source to Bluetooth headphones. Receiver mode turns older car audio or speakers into a Bluetooth destination for a phone, tablet, or computer. The built-in microphone adds call functionality when the adapter is connected to a mobile phone.
Battery life is listed at up to 18 hours, with approximately 16 hours in transmitter mode and 18 hours in receiver mode. Its stated transmission distance reaches 10 meters, allowing reasonable movement around a seat or room. A reset procedure involving the multifunction button is provided if pairing fails.
Compatibility deserves careful attention. The specifications say it works with AirPods and AirPods Pro but is incompatible with AirPods Pro 2, AirPods Pro 3, AirPods 4, and AirPods 4 ANC. iPhone users may also need to reconnect manually. Buyers with those devices should choose another model.
Two-Way Audio Flexibility
The ability to move between transmitter and receiver modes gives this adapter more uses than a dedicated airplane transmitter. It can handle seatback entertainment at home and can also send phone audio to an older vehicle or speaker system.
Check Your Earbuds Before Buying
The explicit exclusions for several newer AirPods models are a significant limitation. Check the model name of your earbuds against the compatibility notes before ordering rather than assuming every Bluetooth product will pair correctly.

In transmitter mode, the adapter accepts AUX or RCA audio sources and can send that signal to two sets of headphones. Receiver mode receives audio from a smartphone, tablet, or computer for playback through a system without Bluetooth. The included AirFly-style dual-prong airplane adapter makes it easier to connect to common seatback entertainment ports.
System memory supports quick reconnection, while LED indicators reveal battery and connection status. USB-C charging takes approximately 1.5 hours, and the product can continue operating while it charges. The stated global safety certifications include FCC, CE, RoHS, and BQB, adding documented compliance information to the feature set.
There are firm exclusions. The product is not compatible with live music, instruments, karaoke, 2.4 GHz synchronization devices, or Bluetooth hearing aids. Those restrictions make sense for a travel-focused device, but they reduce its suitability for specialized audio work or users who need those exact functions.
Useful Charging Flexibility
The ability to recharge through USB-C while continuing to use the adapter is useful before a long flight. It reduces the need to stop listening and recharge whenever the internal battery becomes low during a journey.
Status Details at a Glance
Dedicated buttons and clear LED indicators make the adapter manageable in a dim aircraft cabin. Users can check the current mode and connection without navigating a phone or relying entirely on audible prompts.

Two sets of Bluetooth headphones or earbuds can be connected to one 3.5 mm airplane source. Qualcomm audio technology is combined with aptX Adaptive and aptX HD support for compatible listening devices, while onboard controls and a battery indicator help manage the session.
The three-step procedure is one of the adapter's strongest practical features. Connect to the entertainment jack, place the headphones in pairing mode, and establish the Bluetooth connection. A dual-prong airplane adapter is included to support common aircraft connection layouts.
This is not a general-purpose Bluetooth converter. Relay cannot receive audio, has no microphone, and is not intended for phone calls, televisions, hearing aids, or musical instruments. Travelers who only want to watch in-flight entertainment with one other person will find that focus helpful rather than limiting.
Built Around Airplane Entertainment
The Relay's physical design and included connection accessory focus on seatback use. It avoids distracting features and concentrates on delivering audio to personal wireless headphones over a stable Bluetooth connection.
Codec Support Worth Checking
Advanced codec support can improve the listening result when both the adapter and headphones support the same feature. Because codec availability depends on the paired equipment, checking headphone compatibility before travel remains important.

We may earn a commission when you buy through this link, at no additional cost to you.
In transmitter mode, the adapter streams audio from an airplane, television, computer, car audio system, or another 3.5 mm source to wireless headphones. Receiver mode sends phone or computer audio to wired speakers. TX mode can connect two sets of headphones for shared viewing, while RX mode can remember two source devices for switching.
The LCD shows pairing status, connected devices, and the active mode. That visibility can be especially useful when switching between TX and RX or confirming that both headphones are connected. Battery life is stated at up to 23 hours in transmitter mode and 17 hours in receiver mode, with fast USB-C charging.
Important caveats limit its use. The device has no microphone, does not support Dolby audio, cannot pair with devices requiring PIN input, and is not recommended for musical instruments or professional audio. Low-latency performance also requires compatible headphones, so the feature cannot be guaranteed with every AirPods or earbud model.
Audio and Video Synchronization
The stated latency of approximately 40 milliseconds makes aptX-LL the central feature for video. It can reduce lip-sync issues when both the source and headphones support the technology, although unsupported headphones will not gain the same benefit.
A Helpful Built-In Display
The LCD removes some of the guesswork from pairing and mode selection. It is especially helpful for travelers who switch between entertainment sources or want confirmation that two shared-listening headphones are connected.

We may earn a commission when you buy through this link, at no additional cost to you.
The adapter sends audio from a 3.5 mm source to Bluetooth headphones or earbuds and supports two pairs at once. Compatibility with aptX Adaptive and aptX HD is listed for suitable headphones, while onboard volume controls and a clear battery indicator simplify everyday operation.
Setup requires only plugging the Relay into the airplane jack, activating pairing mode on the headphones, and connecting. The bundled dual-prong adapter is intended to fit common dual-output airplane entertainment connectors, reducing setup friction at the start of a journey.
Like the other Relay entries, it is transmitter-only and has no microphone. It is not designed for calls, TV reception, hearing aids, musical instruments, or receiving audio. That makes it a specialized but understandable purchase for travelers whose main priority is sharing airplane movies with another person.
Convenience for Two Travelers
Supporting two headphone pairs is the strongest reason to choose this adapter over a basic single-listener transmitter. Each person retains a full set of headphones while hearing the same airplane entertainment feed.
Know the Device Boundaries
The Relay performs one role and performs it directly: sending 3.5 mm source audio to Bluetooth headphones. Travelers who expect a microphone, phone-call support, or Bluetooth receiver functionality should select a two-in-one alternative instead.

Buying Guide – How to Choose the Best Bluetooth Headphone Adapters for Flying
The most useful adapter is one that matches your aircraft connection, headphone ecosystem, battery needs, and likelihood of traveling with another listener. These factors separate a focused transmitter from a flexible two-in-one travel device.
Transmitter or Receiver
A transmitter sends audio from a wired 3.5 mm source to Bluetooth headphones, which is the core airplane use case. A receiver does the opposite by receiving audio from a phone or computer and sending it to a wired speaker or stereo. Dedicated Relay models are transmitter-only, while the AirFly Pro 2, SOOMFON, UGREEN, and 2026 Upgrade Pro support both modes.
Choose transmitter-only when your priority is aircraft entertainment and shared listening. Choose a two-in-one model if you also want to connect a phone to an older car, boat, or speaker system.
Single or Shared Listening
Single-listening adapters are sufficient for one traveler but may not be worth adding if you regularly watch with a partner. The Avantree Relay and AirFly Pro 2 family support two sets of headphones, while the UGREEN and SOOMFON descriptions discuss dual connections with mode-specific limitations. Confirm that simultaneous pairing is explicitly supported in the desired transmitter mode.
Shared listening is useful for movies and television, but remember that both sets of headphones must support compatible Bluetooth features. Individual volume adjustment is not guaranteed when two devices are connected.
Battery Life and Charging
Battery life should comfortably exceed the duration of your longest expected trip. Stated runtimes range from up to 18 hours for the UGREEN adapter to more than 25 hours for the AirFly Pro 2 variants and up to 25 hours for the Relay. The SOOMFON provides up to 23 hours in transmitter mode and 17 hours in receiver mode.
For long-haul travel, USB-C charging and the ability to operate while charging add useful resilience. Even so, charge the adapter fully before departure and carry a cable and power source rather than relying on an airport outlet.
Bluetooth Version and Codecs
Bluetooth 5.3 and Bluetooth 6.0 appear among the featured products, but the version alone does not determine audio quality. Codec support can improve stability, detail, or latency when it is supported by both the adapter and the paired headphones. The Relay and AirFly Pro 2 list aptX Adaptive and aptX HD, while the SOOMFON lists aptX Low Latency.
Choose based on your actual headphones. A codec feature provides little benefit if your AirPods, earbuds, Sony model, or Bose headphones do not support it, so check the compatibility information before relying on a listed capability.
Latency and Video Sync
For in-flight films, low latency can help keep dialogue synchronized with the screen. The SOOMFON emphasizes aptX Low Latency and states latency as low as 40 milliseconds when used with compatible headphones. Other products emphasize stable transmission and low-latency performance without giving the same precise measurement.
Latency depends on the complete signal chain. Source support, the adapter's codec, the selected mode, and the headphones all matter, so no adapter can guarantee perfect synchronization with every pair of wireless earbuds.
Headphone and Airplane Compatibility
Most listed headphones work with standard Bluetooth, but specific exclusions matter. The UGREEN listing says it is incompatible with AirPods Pro 2, AirPods Pro 3, AirPods 4, and AirPods 4 ANC, while some products exclude hearing aids, instruments, live music, karaoke, 2.4 GHz synchronization devices, PIN-protected devices, or Dolby audio.
Write down your exact headphone model and check it against the product notes. Also consider the seatback connector, since a dual-prong airplane adapter is included with several models while others depend on a standard 3.5 mm plug.
Controls and Status Information
Physical controls are particularly useful in an airplane cabin where digging through settings can be distracting. The AirFly SE has built-in volume buttons, the Relay includes onboard volume controls and a battery indicator, and the 2026 Upgrade Pro uses LED indicators for battery and connection status. The SOOMFON goes further with an LCD that displays mode and paired-device information.
Choose based on how much feedback you want. Audible prompts suit minimalists, LEDs provide quick visual confirmation, and an LCD offers the most detailed setup information but makes the device slightly more complex.
Travel Size and Extras
Every recommended device is designed to be portable, but the practical extras differ. The Relay includes a dual-prong airplane adapter, the AirFly SE supports use while charging, and the 2026 Upgrade Pro provides cable storage and fast USB-C charging. A compact adapter should fit easily in a personal item, tech pouch, or carry-on pocket.
Look for the accessories that solve a real travel problem rather than judging a product by feature count alone. Dual-prong support, a charging cable, a clear battery indicator, and storage for a short cable can all be more useful than a rarely used feature.
How to Use and Care for Your Bluetooth Headphone Adapters for Flying
Before leaving home, charge the adapter fully, download any required app, and update your wireless headphones. Put the headphones into pairing mode, select transmitter mode on a two-in-one adapter, and connect it to the airplane's 3.5 mm jack. Use the included dual-prong accessory if the seatback connection requires it, then confirm that the first headphone pair is connected before adding a second.
Set the airplane volume low before plugging in the adapter, then raise it gradually. This can prevent an abrupt burst of audio when a connection is established. Use the adapter's volume controls or the headphone controls as needed, and keep the device within easy reach rather than leaving it attached in a position where it could be pulled from the seatback.
After the flight, disconnect the adapter, switch it off, and place it in its pouch. Keep the charging cable with the adapter and recharge it before the next trip. Avoid moisture, extreme heat, and bent connector pins, and clean the 3.5 mm plug with a dry cloth if debris affects the connection.
Frequently Asked Questions
How do I connect Bluetooth headphones to an airplane entertainment system?
Most airplane entertainment systems provide a wired 3.5 mm headphone output. Connect the adapter to that jack, place your Bluetooth headphones in pairing mode, and use the adapter's pairing control to establish the connection. Some adapters also include a dual-prong plug for aircraft connections with two output sockets.
Can I connect two pairs of headphones to one airplane screen?
Yes, if the adapter explicitly supports dual headphone pairing. The Avantree Relay and AirFly Pro 2 variants are designed for two sets of Bluetooth headphones or earbuds. Dual-connection limitations can vary by mode and product, so verify the specifications before adding a second pair.
Do Bluetooth airplane adapters work with any wireless earbuds?
Most standard Bluetooth headphones should connect, but specific models may be excluded. The UGREEN adapter, for example, lists incompatibility with several newer AirPods models. Check the exact model name of your headphones against the manufacturer's compatibility notes before packing the adapter.
What is the difference between transmitter and receiver modes?
Transmitter mode takes audio from a wired source and sends it to Bluetooth headphones. Receiver mode receives audio from a phone, tablet, or computer and sends it through a wired audio system. The Relay models are transmitter-only, while the AirFly Pro 2, SOOMFON, UGREEN, and 2026 Upgrade Pro offer both modes.
Can I use these adapters for phone calls?
It depends on the model. The UGREEN and 2026 Upgrade Pro list a built-in microphone, while the Avantree Relay and SOOMFON explicitly do not include one. Even where a microphone is present, the adapter must be connected to a phone in the appropriate mode and the user's headphones must support calls.
How much battery life do I need for a long flight?
An adapter with at least 20 hours of stated battery life will usually cover a long-haul flight, though actual results depend on mode, volume, and connection stability. The featured runtimes range from up to 18 hours to more than 25 hours. Charging before departure and carrying a USB-C cable provides the best backup.
Will a Bluetooth adapter cause lip-sync delay during movies?
It can, because audio travels through an additional wireless connection. The SOOMFON's aptX Low Latency support is designed to reduce synchronization delay and is listed as low as 40 milliseconds with compatible headphones. Actual performance also depends on the source, adapter mode, and headphone codec support.
Do I need an app to use these airplane adapters?
The supplied descriptions emphasize physical pairing, button controls, and mode switching rather than mandatory app-based operation. Software requirements can vary by model, so check the final manufacturer instructions and update any associated app before traveling if it is provided.
Final Thoughts on Choosing the Best Bluetooth Headphone Adapters for Flying
The Twelve South AirFly Pro 2 is the strongest all-around choice for travelers who want reliable two-in-one operation, two-headphone pairing, and more than 25 hours of stated battery life. The UGREEN Bluetooth 6.0 adapter provides a budget-conscious flexible option, while the AirFly Pro 2 Deluxe is the premium choice for travelers who value its additional finish and feature set.
Prioritize the functions you will actually use. Solo travelers may be well served by the simple AirFly SE, couples may prefer the Relay's dedicated dual-listener design, and video-focused users may appreciate the SOOMFON's display and aptX-LL support. Always check headphone compatibility, connector style, codec requirements, and mode limitations before packing.
Prices, ratings, availability, and product configurations can change, so confirm the current listing and manufacturer details at the time of purchase. Whichever model you choose, charge it fully, test the complete setup with your own headphones before flying, and carry a backup wired option for any aircraft whose entertainment system presents an unexpected connection problem.
