Its primary appeal is the direct solution it offers to the familiar problem of airline-provided wired headsets. The adapter fits into a seatback headphone jack and sends that audio wirelessly to compatible earbuds. It also works with gym equipment, gaming devices, and other 3.5 mm sources, making it more useful than an airline-only accessory. Built-in volume buttons provide basic control without requiring an app.
The AirFly SE can be used while charging with the included USB-C cable, reducing the chance of losing audio midway through a long trip. That is especially valuable for flights where entertainment access may be needed throughout the journey. Its lightweight, portable form also avoids adding unnecessary bulk to a carry-on or personal tech pouch.
This is an attractive option for a solo traveler who wants dependable wireless audio without a complicated setup. Although it does not advertise the same dual-headphone sharing or receiver functionality found on more versatile models, it focuses on the basics that matter in an aircraft. It is a strong pick for users who value simplicity, compactness, and charging flexibility.
Freedom From Airline Headset Cords
Connecting AirPods or earbuds to the adapter replaces the loose wired headset with a private wireless listening setup. That can be more comfortable on a long flight and leaves the seatback jack free from a dangling cable.
Battery Support for Extended Journeys
The stated battery life exceeds 20 hours, while use during charging adds another layer of flexibility. Travelers can keep listening without waiting for a full recharge when the adapter is connected to a suitable power source.

We may earn a commission when you buy through this link, at no additional cost to you.
Qualcomm audio technology and aptX Adaptive and aptX HD support are listed for compatible headphones, making this a consideration for users who care about wireless sound quality. A battery life of up to 25 hours suits long-haul travel, while onboard volume controls and a battery indicator help manage the device without an app.
The setup process is refreshingly direct. Plug the Relay into the 3.5 mm jack, put the headphones into pairing mode, and connect. A dual-prong airplane adapter is included, which helps accommodate the dual-output configuration found on many aircraft seatback entertainment units.
The Relay is best for two travelers who both want to watch the same inflight content. It is less flexible outside that role because it is transmitter-only, lacks a microphone, and is explicitly not intended for calls, hearing aids, instruments, TVs, or receiving audio. Within its dedicated flight niche, however, the dual-listener design is unusually useful.
One Screen, Two Headphone Pairs
The dual-pairing capability is the Relay's defining advantage. Both travelers can listen to the same airplane entertainment screen without sharing a single wired earpiece or relying on a splitter.
Codec Support for Compatible Headphones
Support for aptX Adaptive and aptX HD can be valuable with compatible headphones. Actual performance depends on the headset and its codec support, so checking headphone compatibility before departure is wise.

Bluetooth 6.0 is the advertised platform, with a stated emphasis on faster pairing, stable transmission, and improved audio-video synchronization. Its 10-meter range gives users room to move around a home, office, or travel space without immediately losing the signal. The included built-in microphone is also useful when the adapter is connected to a phone for music and calls.
Battery life reaches up to 18 hours in receiver mode and 16 hours in transmitter mode. That is suitable for many journeys, although it is shorter than several premium competitors. Pairing failures can be addressed by holding the multifunction button for ten seconds while the device is powered off, according to the product guidance.
This is the budget-oriented pick for someone who wants one adapter for several travel and home uses. Compatibility deserves careful attention: the listing specifically excludes AirPods Pro 2, AirPods Pro 3, AirPods 4, and AirPods 4 ANC. It also notes that iPhones cannot automatically reconnect and require manual reconnection.
Two Operating Modes Add Flexibility
Transmitter mode turns a 3.5 mm source into Bluetooth audio, while receiver mode does the reverse for older wired systems. The correct mode must be selected before use, but the broader utility can justify the extra setup step.
Check Headphone Compatibility First
The listed exclusions for several newer AirPods models are important. Buyers should verify the exact headphone model and accept the stated manual-reconnect behavior before considering this adapter.

Its most flight-relevant feature is dual-listener audio sharing. Two sets of headphones can be connected in transmitter mode, which makes it useful for a couple, family members, or two travel companions watching the same program. Auto-pairing at power-on and system memory for quick reconnection reduce friction across trips.
Battery life exceeds 20 hours, and the stated one-and-a-half-hour USB-C recharge can be completed while the device remains in use. Dedicated buttons handle volume and mode changes, while clear LEDs indicate battery and connection status. The package also includes a dual-prong airplane-style adapter and a QR guide.
This adapter makes sense for users who want more than a disposable flight accessory. Its limitations are specific but meaningful: it is not compatible with live music, instruments, karaoke, 2.4 GHz-synchronized devices, or Bluetooth hearing aids. For ordinary consumer entertainment, the broad feature set is compelling.
Share Without Splitting Cables
Dual-listener transmission lets two people hear the same audio from one source. That is especially helpful on flights where the seatback interface may not support multiple wired headsets cleanly.
Charging Through a Long Flight
Use while charging helps cover extended journeys, while the short stated recharge time is convenient during a layover. A dedicated battery indicator helps avoid waiting for an avoidable interruption.

Buying Guide – How to Choose the Best Bluetooth Headphone Adapters for Flying
The most useful flight adapter balances reliable wireless transmission, long battery life, straightforward pairing, and compatibility with your headphones. The right operating mode and shared-listening features depend on how you travel.
Transmitter or Receiver Mode
An airplane seatback sends wired audio through a 3.5 mm jack, so the primary function you need is transmitter mode. A receiver does the opposite: it receives Bluetooth audio from a phone and forwards it to a wired stereo, speaker, or car system. Choosing a dual-mode model offers flexibility beyond the aircraft, while a transmitter-only device offers a more specialized and potentially simpler experience.
Battery Life and Charging
Long-haul flights demand enough battery to survive the entire journey. Adapters in this comparison list stated runtimes ranging from up to 18 hours to more than 25 hours in certain modes. Consider whether the device supports operation while charging, because that can be valuable during a layover or on flights longer than its normal battery estimate. USB-C charging is also convenient for travelers who already carry modern cables.
Shared Listening Capability
Two-headphone pairing lets two travelers listen to the same entertainment source without splitting a wired headset. This is particularly useful for couples, families, and companions who want to watch a movie together. Some adapters support independent volume adjustment in dual mode, while others do not, so check that detail if each traveler needs separate control.
Bluetooth Version and Codecs
Bluetooth versions and codecs can influence connection stability, latency, and perceived sound quality. Bluetooth 5.3 or 6.0 products may offer modern transmission characteristics, while aptX Adaptive, aptX HD, and aptX Low Latency support can benefit compatible headphones. A codec only works as intended when the paired headset supports it, so verify compatibility before purchasing.
Latency for Movies and Games
Audio that arrives behind the on-screen action can make dialogue feel out of sync. The SOOMFON adapter specifically emphasizes aptX Low Latency and a stated low latency figure, while the AirFly Pro 2 models list low-latency-oriented codec support. Low-latency claims are most meaningful with compatible headphones, so model-to-model verification remains important.
Connector and Airplane Compatibility
Most seatback entertainment systems use a 3.5 mm connection, but the shape and number of sockets can vary. A dual-prong airplane adapter can help bridge common configurations, while a standard 3.5 mm plug covers many other sources. Consider the adapter's included accessories and make sure it can physically fit the available aircraft connection.
Controls, Display, and Status
Physical volume and mute buttons make it easier to manage audio without an app or phone. LED indicators provide a quick battery and connection overview, while an LCD may show the active mode, paired devices, and pairing status. Simpler indicators save space, but a display can be helpful when switching among transmitter and receiver roles or connecting two headphones.
Calls and Specialized Equipment
A built-in microphone is not universal. Several flight-focused adapters omit it because they are intended only to transmit entertainment audio to headphones. These transmitter-only products may be unsuitable for calls, hearing aids, instruments, or professional audio. UGREEN and the 2026 Upgrade Pro include a microphone, while the SOOMFON explicitly lacks one. Check these limits against your intended use.
How to Use and Care for Your Bluetooth Headphone Adapters for Flying
Before leaving home, charge the adapter fully and test it with the exact headphones you plan to use. Put the headphones into pairing mode, connect the adapter to a phone or other 3.5 mm source, and confirm that sound plays correctly. For an airplane, bring the dual-prong adapter if the seatback connection requires it and place the adapter in TX mode.
On the aircraft, start with the volume low, plug the adapter into the headphone socket, and pair the first set of Bluetooth headphones. If the model supports two listeners, complete the second connection before starting entertainment. Keep the adapter accessible for volume or mode controls, and avoid changing modes unless the product instructions call for it.
After the trip, switch the adapter off and store it in a small protective pouch. Charge it before the next journey, keep the 3.5 mm and USB-C ports free of debris, and avoid using the adapter with instruments or hearing aids if the manual says it is unsupported. Periodic testing helps identify a weak battery or changed headphone pairing behavior before departure.
Frequently Asked Questions
How do I connect Bluetooth headphones to an airplane entertainment system?
Choose an adapter with transmitter mode, plug it into the airplane's 3.5 mm headphone jack, and power it on. Put your Bluetooth headphones into pairing mode and select the adapter from their available-device list. Confirm that the adapter is in TX mode, lower the airplane volume initially, and use a dual-prong adapter if the seatback socket requires it.
Can I use two sets of AirPods with one airplane screen?
Yes, if the selected adapter supports dual-headphone pairing. The Avantree Relay, 2026 Upgrade Pro, AirFly Pro 2 models, and SOOMFON adapter are described as supporting two sets of headphones in transmitter mode. Check whether the model provides independent volume adjustment for each pair, since some shared-listening modes use one combined volume level.
What is the difference between transmitter and receiver modes?
Transmitter mode takes audio from a wired 3.5 mm source and sends it to Bluetooth headphones. Receiver mode receives audio from a phone, tablet, or computer and sends it through a wired stereo or speaker. Airplanes generally require transmitter mode, while receiver mode is useful for older car systems, boat audio, and other equipment without Bluetooth.
Will a Bluetooth flight adapter work with my AirPods?
Most adapters support common AirPods, earbuds, and Bluetooth headphones, but compatibility can vary by exact generation. The UGREEN listing specifically excludes AirPods Pro 2, AirPods Pro 3, AirPods 4, and AirPods 4 ANC, and it notes that iPhones require manual reconnection. Verify the model and operating-system requirements before purchasing.
Do I need an adapter with a microphone for an airplane?
Usually not. Airline entertainment is one-way audio, so microphone support is unnecessary for watching movies. A microphone becomes relevant when using the adapter with a phone for calls. Adapters without one, including Avantree Relay and SOOMFON models, are therefore suitable for inflight entertainment but not intended for phone conversations.
Can I watch movies without the audio drifting out of sync?
The risk of drift depends on the adapter, codec, and headphones. Adapters supporting aptX Low Latency or aptX HD Adaptive can provide better synchronization with compatible headsets. The SOOMFON lists latency as low as 40 milliseconds, but the paired headphones must support aptX Low Latency to gain the full stated benefit.
How long should I charge the adapter before a flight?
A full charge is the safest starting point. Listed battery runtimes range from up to 18 hours to more than 25 hours depending on the model and mode. For a very long journey, consider an adapter that can operate while charging, and bring a compatible USB-C cable if your chosen model does not include one.
Can I use these adapters with gym equipment or a television?
Yes, when the source has a compatible 3.5 mm audio output and the adapter supports transmitter mode. A dual-function model can also work in reverse with a wired speaker system. Specialized live-music equipment, instruments, hearing aids, and professional audio setups may be unsupported, so check the product limitations before connecting them.
Final Thoughts on Choosing the Best Bluetooth Headphone Adapters for Flying
The UGREEN Bluetooth 6.0 adapter stands out as the budget pick because it combines transmitter and receiver modes, a built-in microphone, and useful range. The AirFly Pro 2 is the strongest all-around option for modern Bluetooth features, two-headphone sharing, and long battery life. Its Deluxe version is the premium recommendation for shoppers who prioritize codec support and the highest listed rating in the group.
For most flights, prioritize transmitter compatibility, enough battery for the full journey, and a connector that fits the seatback. Dual pairing matters if two people will watch together, while low-latency codecs matter most for films and games. If the adapter will also serve in a car, gym, or older stereo system, a dual-mode design is the more flexible choice.
Ratings, specifications, availability, and prices can change, so confirm the current product listing before buying. Check your exact headphone model, confirm that the necessary airplane adapter is included, and test the pairing process at home. Those few minutes of preparation can make the next flight much more comfortable.
