Best Airplane Bluetooth Adapters for Wireless Headphones in 2026
The best airplane Bluetooth adapters for AirPods and wireless headphones, including the best value, TX/RX, solo, and compact dual-headphone picks
Quick Take
- The Avantree Relay is the best airplane Bluetooth adapter for most travelers because it supports two headphones, runs for up to 25 hours, and includes a two-prong airline adapter.
- Buy the AirFly Pro 2 instead if receiver mode matters outside the plane.
- The AirFly SE is the simple solo pick; the MEE audio Connect Air is the compact alternative for two listeners.
The Avantree Relay is the best airplane Bluetooth adapter for most travelers. It connects one or two pairs of AirPods or other Bluetooth headphones to a seatback screen, lasts up to 25 hours, and includes the two-prong adapter still found on some airplane audio systems.
The Relay is not the only sensible choice. The AirFly Pro 2 adds receiver mode for wired car stereos and speakers, the AirFly SE is enough for one listener, and the MEE audio Connect Air fits dual-headphone support into a smaller body. These recommendations are based on current manufacturer specifications and TrekSavvy's existing AirFly comparisons; they do not imply hands-on testing of every model.
Best overall: Avantree Relay
The Relay covers the in-flight features that matter without charging extra for the airline accessory. It pairs with two sets of headphones, has onboard volume controls and a four-level battery indicator, and includes both single- and dual-prong connections for seatback systems.
Avantree lists aptX Adaptive, aptX Low Latency, aptX HD, aptX, and SBC support. Your headphones must support the same codec to use it, so AirPods and other non-aptX earbuds fall back to a compatible standard rather than gaining aptX just because the transmitter supports it.
Buy it if: You want the strongest flight-focused feature set and do not need receiver mode.

Best for transmitter and receiver use: Twelve South AirFly Pro 2
The AirFly Pro 2 is the better adapter when the job does not end with seatback entertainment. Its TX mode sends airplane audio to one or two wireless headphones. Switch to RX mode and it can send music from a phone to a wired car stereo, speaker, or other AUX input.
It also has dedicated Pair 1 and Pair 2 controls, onboard volume and mute controls, USB-C charging, and more than 25 hours of battery life. The regular version does not include a two-prong airline adapter. The AirFly Pro 2 vs Deluxe comparison shows why the standard model remains the better default unless you specifically need that adapter.
Buy it if: You will use receiver mode away from the plane or prefer its dedicated pairing controls.

Best for one listener: Twelve South AirFly SE
The AirFly SE is the simple answer for a solo traveler. It connects one pair of Bluetooth headphones, runs for up to 20 hours, and charges over USB-C. There is no second-headphone connection or receiver mode to pay for or configure.
That simplicity is also the limitation. The Pro 2 is easier to justify if you sometimes travel with a partner or want the adapter to handle more than airplane audio. Our AirFly Pro 2 vs AirFly SE comparison covers the tradeoff directly.
Buy it if: You always listen alone and want the least complicated AirFly.
Compact dual-headphone alternative: MEE audio Connect Air
The Connect Air measures 1.8 by 1.5 by 0.6 inches and supports two sets of Bluetooth headphones in a compact square body. MEE rates it for 20 hours with one headphone connection or 15 hours with two, and it charges over USB-C.
Its codec list includes SBC, aptX, and aptX Low Latency. There are no onboard volume buttons, so volume is controlled from the seatback system or other audio source. It also does not include a two-prong airline adapter.
Buy it if: You want a small dual-headphone transmitter and do not mind shorter battery life with two listeners.
What matters in an airplane Bluetooth adapter
One headphone or two
The AirFly SE is enough for one person. Choose the Relay, AirFly Pro 2, or Connect Air if two people may share a seatback screen. Dual pairing is worth buying upfront because it cannot be added to a single-headphone transmitter later.
Airline two-prong support
Seatback systems may use a normal 3.5 mm jack or an older two-prong socket. The Relay includes the adapter for both. Twelve South sells it separately or bundles it with the AirFly Pro 2 Deluxe. The regular AirFly Pro 2, AirFly SE, and Connect Air do not include it.
Latency and codecs
Bluetooth video delay depends on the transmitter and headphones sharing a low-latency codec. A transmitter's aptX support does not make AirPods or another SBC/AAC-only headphone use aptX. Airline screens can also introduce their own delay, so no adapter can promise perfect lip sync with every aircraft and headphone combination.
Receiver mode
Receiver mode does not improve airplane performance. It matters only if you also want to send Bluetooth audio from a phone into a wired car stereo, hotel speaker, or home audio system. The AirFly Pro 2 is the pick here; the other three are transmitters.
