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

Twelve South’s entry-level Bluetooth transmitter features an integrated 3.5mm cable, meaning all you need to do is plug it into the seatback entertainment system and pair it with your favorite pair of wireless earbuds or noise-canceling headphones. It doesn’t last as long as the step-up AirFly Pro and Pro Deluxe — nor does it allow for two simultaneous connections — but it still lets a single user eke out 20 hours of continuous playback on 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 always tuned to CNN, SportsCenter, or reruns of Friends.
