Connect the AirFly Pro 2 to a USB-C headphone adapter on your iPad, and multiple kids can pair their own wireless headphones to the same iPad simultaneously. No more sharing one pair of earbuds or fighting over the volume.
I don't usually get this excited about accessories. But the AirFly Pro 2 genuinely surprised me — and I say that as someone who's been through enough travel gadgets to know when something is actually solving a problem versus just adding complexity. This is a Bluetooth transmitter the size of a lipstick cap that plugs into any 3.5mm headphone jack and turns it wireless.
Fresh out of the box — no complicated setup, just the transmitter and a quick guide.
It also comes in two colors, and I ended up picking up one of each — a white one and a black one — so I could match whichever seat jack or device I'm plugging it into.
Picked up both colors — white and black.
Spec sheets don't always give you a real sense of scale, so I laid it next to my bag and the included guide paper to show the width, then stood it next to the box to show the height. It's genuinely tiny — small enough that it disappears in a jacket pocket or the little seatback pouch on a plane.
Next to my bag and the guide paper for width, and next to the box for height.
I tested this on a 12-hour flight to China and it made the entire experience genuinely better. Plugged into the headphone jack on the in-flight entertainment screen, pressed the button, my headphones connected within seconds. Audio came through crystal clear — no dropouts, no weird delay, no sync issues during movies. The whole 12 hours, and it never ran out of battery.
On the 12-hour flight to China — still going strong at landing, no recharge needed.
The audio quality is excellent too. I was skeptical going in — Bluetooth over a 3.5mm transmitter sounds like it should be a compromise, but it doesn't feel like one in practice.
This is the feature that pushed me from "good gadget" to "genuinely recommend to everyone." The AirFly Pro 2 supports two Bluetooth headphone connections at the same time. On the flight, my travel companion and I both connected our own headphones to the same seat entertainment jack and watched the same movie together, completely wire-free. That's a feature I didn't know I wanted until I had it, and now I can't imagine flying without it.
I've been reaching for this thing in situations I didn't originally buy it for. Hotel TVs with no Bluetooth. The treadmill at the gym. My car's aux port when I want to use headphones instead of speakers. It even plugs straight into a PS5 controller's headphone jack, so anything with a 3.5mm jack becomes wireless-headphone compatible.
Also plugs straight into a PS5 controller for wireless headphone audio while gaming.
A few genuine gaps worth knowing about. There's no LCD screen, so you can't see which headphones are connected or what the battery percentage is. The Avantree Voyager has this and it's a legitimate advantage if you're managing multiple pairs. It doesn't come with a hard case — just a soft pouch. And the connection process, while generally smooth, isn't completely obvious the first time. Read the instructions before your first flight, not at 35,000 feet.
None of these are dealbreakers. The core experience — wireless audio from any 3.5mm source, zero lag, dual pairing — is executed so well that the missing features feel like future wishlist items rather than reasons not to buy.
Anyone who travels regularly and uses wireless headphones. Full stop. If you're on planes more than twice a year, this pays for itself in comfort before the end of your second flight. At $59.99 it's not cheap for an adapter, but it's the kind of thing that quietly becomes a permanent resident in your travel bag. Trust me on this one.
