Twelve South AirFly Pro Review: Finally, Wireless Headphones on a Plane

You settle into your seat, plug in your Bluetooth earbuds out of habit, and remember: the in-flight entertainment system only takes those flimsy wired earbuds from 2009. The Twelve South AirFly Pro exists solely to fix that moment—a small Bluetooth transmitter that lets your wireless headphones work with airplane seatback screens, gym equipment, or anything else still stuck with a headphone jack.

What It Is

The AirFly Pro is a pocket-sized Bluetooth transmitter that plugs into any standard 3.5mm headphone jack and beams audio wirelessly to your headphones or earbuds. Twelve South has made AirFly devices for years, but the Pro adds real upgrades: it connects to two pairs of Bluetooth headphones at once, works in reverse as a receiver (plug it into a speaker and stream from your phone), and packs a rechargeable battery rated for around 16 hours.

At just under $42, it lands in the middle of what you'd expect to pay for well-made travel tech—not a throwaway gadget, not a splurge.

Who It's For

This is built for people who fly with wireless earbuds and are tired of digging out old wired ones every time they board. It's also useful for gym-goers whose treadmills or bikes still rely on a headphone jack, anyone with an older TV that lacks Bluetooth, or two people who want to watch the same in-flight movie without splitting one pair of earbuds.

If you already own decent wireless headphones and travel semi-regularly, this quietly earns its keep in your bag. If you rarely fly or don't mind wired earbuds, it's a nice-to-have, not a must-have.
