My body refuses to fall asleep on phim set dich nhauplanes, though not for lack of trying. I've stayed up late before flights, booked red-eyes, popped melatonin, ordered a couple glasses of red wine from the beverage cart — and yet there I sit, wide awake in my economy seat.

I need to keep busy with in-flight entertainment. I'm not built to be raw-dogging flights, and that tiny seatback screen keeps me sane at 30,000 feet. If I can't binge last year's Oscar nominees or lock into a weird HBO documentaryfor a few hours, I start to think a little too hard about the safety record of the Boeing 737 Max I'm trapped inside. (I am very fun to travel with.)

Knowing this, my extremely brilliant and thoughtful husband gifted me a Twelve South AirFly Pro for Christmas last year. This $54.99 Bluetooth transmitter gadget lets me watch in-flight movies with my wireless Bose headphones. It's not a glamorous device — it's just a dongle with an aux cable on one end — but it's an easy way I make flying more comfortable.

I used the AirFly Pro for the first time on round-trip flights between Chicago and London this spring, and I'll never fly without it again. Also worth noting: It's on sale.

Fly like a Pro

While wireless headphones and earbuds are vastly more popular than wired models nowadays, the airline industry hasn't adjusted accordingly. (United and Delta have added Bluetooth-enabled screens to some of their planes, but I've yet to fly on one personally.) To watch movies and shows on that seatback screen, you still have to plug in wired earphones with an old-fashioned 3.5mm audio jack.

Some airlines hand out complimentary cheapo wired buds for long-haul flights, but they sound terrible and don't offer a lick of noise cancellation. The AirFly Pro exists to bridge the technology gap for a better in-flight entertainment experience.

Setting up the AirFly Pro is ridiculously simple:

• Plug it into the screen or armrest

• Press and hold the power button

• Turn on your headphones

• Wait for them to pair

If you're traveling with someone, you can even connect the AirFly to both of your headphones at the same time. My AirFly Pro paired instantly with my Bose headphones and remembered them on my return flight.

The AirFly Pro's audio sounded fine to me, and I never had connection issues. I did notice that in-flight announcements were a split-second delayed compared to the plane's PA system, but the sound and dialogue on movies always lined up perfectly.

Twelve South has the AirFly Pro rated at 25 hours of battery life, and that seemed accurate. Mine lasted the full eight-hour flight from Chicago to London, a few hours beyond that (because I forgot to turn it off), and then most of the way through my nine-hour return flight. When it finally died, 10 minutes of charging gave it enough battery for at least 30 more minutes before we landed.

The biggest downsides to the AirFly Pro? The fact that you can't use it while it's charging, and that it's kind of expensive for a Bluetooth transmitter. That said, it works like a charm and feels like a future-proofed purchase, since planes probably aren't getting rid of their 3.5mm audio jacks anytime soon.

Where to buy the AirFly Pro

The $54.99 AirFly Pro (currently on sale for $44.99) comes with a soft travel pouch and a keyring cap in addition to its charger. For $20 less, you can pick up the AirFly SE, but you lose a little battery life and the dual listening mode.

I've seen the AirFly line sold at airports before, but I'd recommend snagging one before you jet off on your next trip, as my Pro model is easy to find on sale. At the time of writing, Amazon and Best Buy both had it listed for $13 off. The AirFly Pro is also available as part of some Bose QuietComfort Ultra headphone and earbud bundles.
