Who Should Buy This#
The AirFly Pro solves one annoying problem cleanly: you own wireless earbuds, but airplanes, treadmills, and older gear still demand a wired plug. It hands that legacy 3.5mm jack a Bluetooth radio, so your AirPods finally work everywhere. Cheaper dongles exist, but few match this one's dual-headphone pairing, low-latency audio, and all-day battery.
Perfect for:
- Frequent flyers who want to watch seatback movies through their own noise-cancelling headphones instead of scratchy airline earbuds
- Couples and travel buddies who need two pairs of headphones on one screen for shared flights or road trips
- Gym regulars who hate the tangle of wired earbuds on a treadmill or elliptical with a built-in screen
- Anyone with older audio gear who wants to stream Bluetooth into a wired speaker, soundbar, or rental-car aux port
Design & Build Quality#
The AirFly Pro is barely larger than a USB thumb drive, with a smooth white shell and a short, flexible 3.5mm cable that tucks against the body. A single multifunction button handles power, pairing, and mode switching, and a small LED reports status with color cues. The whole thing weighs next to nothing, so it disappears into a pocket or a bag's accessory pouch.
The included keyring attachment is the smart touch. Clip it to a backpack zipper or a set of keys and the AirFly Pro stops vanishing into the bottom of a bag. Twelve South also ships a travel pouch and a USB-C charging cable in the box.
Key Features#
Transmit Mode for Airplane and Gym Screens#
Plug the AirFly Pro into any 3.5mm headphone jack and it broadcasts that audio to your wireless headphones. This is the headline use case: airplane seatback entertainment systems and gym cardio machines almost universally still use wired jacks, locking out modern earbuds. With the AirFly Pro in transmit mode, your AirPods Pro or Bose headphones connect to the in-flight movie or the treadmill TV in seconds.
Because it pairs in seconds and remembers your headphones, you can be watching a film before the plane finishes boarding.
Dual-Headphone Pairing#
The AirFly Pro connects to two Bluetooth headphones at the same time from a single 3.5mm source. On a long flight, you and a seatmate can watch the same movie, each with your own headphones, without splitter cables or shared earbuds. It works the same way on a shared tablet or a gym screen.
25+ Hour Battery Life#
A full charge delivers 25+ hours of playback, which outlasts even ultra-long-haul routes like a 17-hour nonstop. You charge it over the included USB-C cable, the same connector your phone or laptop likely uses, so there is no proprietary brick to pack. For most travelers, a single charge covers an entire round trip.
Receive Mode for Legacy Audio Gear#
Flip the AirFly Pro into receive mode and it works in reverse: it accepts a Bluetooth stream and outputs it through the 3.5mm plug. That turns a wired speaker, a soundbar, or an older car stereo's aux port into a Bluetooth target. One small adapter handles both directions, so it earns its place in a travel kit twice over.

Low-Latency Audio#
The AirFly Pro supports aptX Low Latency on compatible headphones, which keeps sound tight to the picture. On a seatback movie, that means lips and dialogue stay in sync instead of drifting, the lag that makes cheap transmitters unwatchable. Standard SBC and aptX are supported too, so it falls back gracefully with any Bluetooth headphones.
