Twelve South AirFly Pro Bluetooth Transmitter/Receiver

The Twelve South AirFly Pro is a compact Bluetooth transmitter and receiver that wirelessly connects two headphones to any 3.5mm audio jack and runs over 25 hours per charge.

Whether you're on a plane, at the gym, or watching TV, the AirFly Pro removes the need for cords and lets modern Bluetooth headphones pair with legacy audio sources. It supports two simultaneous headsets, boasts Bluetooth 5.0, and includes aptX Low Latency for tighter audio sync. The pocket-friendly design and included travel pouch make it convenient for commuting, travel, or shared listening at home.

How do I use AirFly Pro on an airplane or with in-seat entertainment?

Set the AirFly Pro to transmitter mode, plug it into the aircraft’s 3.5mm jack, and pair your wireless headphones. It emulates a wired audio source so you can enjoy movies and TV without tangles or adapter hassles.

• Plug into the seat’s headphone jack and turn on transmitter mode.
• Pair up to two Bluetooth headsets simultaneously.
• Use aptX Low Latency with compatible headphones for reduced delay.
• Charge while using via USB-C when long-haul flights require extra power.

Can AirFly Pro connect wired speakers or a car stereo to my phone?

Yes — switch AirFly Pro to receiver mode to make non-Bluetooth systems accept audio from your phone, tablet, or laptop. This is handy for rental cars, older stereo equipment, or boat speakers that only have a 3.5mm input.

• Enable receiver mode and plug the adapter into the device’s aux input.
• Pair your phone or tablet over Bluetooth and stream audio wirelessly.
• Works with Bluetooth 5.0 for a stable, energy-efficient connection.
• Includes a keychain holder and pouch for quick setup on the go.

What audio quality and latency can I expect for gaming and movies?

AirFly Pro supports aptX and aptX Low Latency codecs for improved fidelity and reduced lip-sync lag on compatible headphones. While standard SBC works broadly, aptX LL provides the best experience for gaming and video where timing matters.

• aptX Low Latency minimizes audio delay with supported headsets.
• aptX offers clearer, richer sound than SBC when both devices support it.
• Bluetooth 5.0 improves range and connection stability compared to older versions.
• Dual-headphone pairing for shared listening without splitting cables.

How long does the battery last and can I use it while charging?

The internal battery delivers more than 25 hours of continuous use on a full charge, making it reliable for long travel days. You can also use the AirFly Pro while charging via the included USB-C cable so your audio doesn't stop mid-flight.

• 25+ hours of battery life on a single charge for long outings.
• USB-C charging for faster, modern power delivery.
• Device remains fully operational while plugged into power.
• Includes travel pouch and keychain for secure transport.

Who is this for? The Twelve South AirFly Pro is designed for travelers, commuters, and anyone with modern Bluetooth headphones who still encounters 3.5mm audio jacks. If you frequently use airplanes, gym machines, rental cars, older TVs, or home stereo gear that lacks Bluetooth, the AirFly Pro bridges the gap without replacing your existing equipment. It suits couples or friends who want to share audio, gamers who need low-latency wireless sound, and users who value long battery life and a portable, durable adapter. With a simple interface and broad codec support, it’s a practical accessory for upgrading legacy audio sources to work with current wireless headphones.
