Learn how to connect and use the Deluxe International Airline Headphone Adapter with your AirFly on dual-prong in-flight entertainment systems.
Quick Answer
The Deluxe International Airline Headphone Adapter lets you use your AirFly (sold separately) with dual-prong in-flight entertainment jacks. Simply plug the adapter into the airplane's two-prong headphone outlet, then insert your AirFly into the adapter's single 3.5mm port. This bypasses the need for wired airline earbuds and keeps your own wireless headphones connected.
What You Need Before You Start
You'll need the Deluxe International Airline Headphone Adapter and your AirFly (any model). The adapter is designed specifically for the dual-prong headphone outlets found on many long-haul aircraft. It does not work with standard single-jack or USB-C audio ports. Make sure your AirFly is charged and paired with your Bluetooth headphones before your flight.
Keep the adapter in your carry-on. It's small and easy to misplace. Consider storing it inside your AirFly's case or a dedicated travel pouch.
Common Pitfalls to Avoid
Don't force the adapter into a single-prong jack. It will not fit and could damage the prongs. Also, the adapter does not include an AirFly—you must purchase that separately. If your AirFly battery dies mid-flight, you'll need a backup wired pair, so carry one just in case.
Step-by-Step Setup Guide
- Locate the dual-prong outlet on your seat: Check the armrest or seat-back screen for a headphone jack with two small holes (one for left audio, one for right). This is common on Boeing 777, 787, and Airbus A350/380 aircraft. If you only see one round jack, you don't need this adapter. Save it for a future flight.
- Plug the Deluxe adapter into the dual-prong outlet: Align the two metal prongs on the adapter with the two holes and push gently until fully seated. A slight click indicates a secure connection. Don't twist or force it. If it doesn't slide in easily, verify you're using the correct outlet.
- Insert your AirFly into the adapter's single 3.5mm port: Take your AirFly (any model) and plug its 3.5mm audio plug into the round port on the adapter. The AirFly should sit snugly. Make sure your AirFly is already charged and in pairing mode before inserting.
- Power on your AirFly and connect your Bluetooth headphones: Press the AirFly's power button. It will enter pairing mode automatically. Select 'AirFly' in your headphones' Bluetooth settings. Once paired, you'll hear the in-flight audio wirelessly. If your headphones don't connect, turn off Bluetooth on other nearby devices to avoid interference.
- Adjust volume and enjoy: Use your headphones' volume controls first, then fine-tune with the in-flight screen's volume slider if available. The adapter does not have its own volume control. Some airlines limit maximum volume at the source. If it's too quiet, try noise-isolating earbuds instead of over-ears.
