Twelve South AirFly SE Bluetooth Audio Transmitter Adapter

The Twelve South AirFly SE is a pocket-sized Bluetooth transmitter that converts any 3.5mm audio jack into a wireless feed for AirPods and Bluetooth headphones.

Whether you’re on a plane, using a hotel TV, working out on gym equipment, or gaming on a console, the AirFly SE bridges legacy audio ports and modern wireless earbuds. It pairs quickly with AirPods, wireless earbuds, or headphones, runs for more than 20 hours per charge, and stays small enough to slip into a travel pouch.

How does AirFly SE connect my AirPods to in-flight entertainment or TV speakers?

AirFly SE plugs into a device’s 3.5mm headphone jack and broadcasts the audio over Bluetooth to your paired earbuds. Pairing is straightforward, and the adapter maintains a stable link designed for low-latency listening during video playback.

• Plugs into any standard 3.5mm audio jack — in-flight screens, hotel TVs, and gym consoles.
• Pairs with two Bluetooth headsets simultaneously for shared listening.
• Simple pairing button and status LED to confirm connections quickly.

What kind of battery life and charging options does it offer for long trips?

The built-in battery provides over 20 hours of continuous playback on a single charge, suitable for long-haul flights or multi-day trips without frequent recharging. When power runs low, you can use the included USB-C cable to charge while still listening, so audio never has to stop.

• 20+ hours of battery life for extended travel sessions.
• USB-C charging for fast, modern power delivery.
• Can be used while charging to maintain playback during long flights.

Will AirFly SE fit in my travel kit and how easy is it to use on the go?

AirFly SE is compact and lightweight, designed to tuck into carry-on pockets, camera bags, or gym lockers with minimal bulk. Controls are intuitive — a pairing button and volume buttons let you manage audio without navigating device menus.

• Small, pocket-friendly footprint for packing into travel pouches.
• Durable construction to handle daily travel use.
• Easy-to-press physical buttons for volume and pairing while moving.

Can it support multiple headphones or work with different devices?

Yes — AirFly SE can connect to two Bluetooth headsets at once, allowing two people to listen to the same source. It’s platform-agnostic, so it works with airline systems, gym machines, TVs, game consoles, and any device that offers a 3.5mm output.

• Dual-output Bluetooth pairing for shared listening sessions.
• Compatible with AirPods, wireless earbuds, and over-ear Bluetooth headphones.
• Works with gaming consoles, portable players, and any device with a headphone jack.

Who is this for? Frequent travelers, commuters, and anyone who still encounters devices with 3.5mm jacks but wants a wireless listening experience will find AirFly SE especially useful. It’s great for couples sharing in-flight movies, gym-goers using cardio machines, or gamers who want to use their Bluetooth headphones with consoles that lack native wireless support. If you prioritize compact design, long battery life, and simple setup to ditch cords without replacing your existing headphones, AirFly SE is a practical travel tech accessory.
