Twelve South’s travel-friendly Bluetooth dongle is on sale for its best price yet

U Twelve South AirFly SE it’s one of those gadgets that can make long flights a little faster, allowing you to eschew the poor pair of complimentary headphones you get with most airlines in favor of your own set of Bluetooth cans. And now, it is for sale on Amazon and Best Buy for $29.99 ($5 off), which is a new all-time low.

Twelve South’s entry-level Bluetooth transmitter features a built-in 3.5mm cable, meaning all you have to do is plug in your seatback entertainment system and pair it with your favorite pair of wireless headphones or earphones of noise cancellation. It doesn’t last as long as the step AirFly Pro and Pro Deluxe – nor does it allow two simultaneous connections – but it also allows a single user to achieve 20 hours of continuous playback with a single charge. Plus, it works with virtually any standard audio jack, making the compact dongle an easy way to add Bluetooth connectivity to older devices…including that aging treadmill at the gym that’s still tuned to CNN, SportsCenter, or reruns of friends.
