Wireless audio adapter for 3.5mm sources

The SuperTooth 12-1911 AirFly Pro adds Bluetooth 5.0 to any device with a 3.5mm auxiliary jack. It transmits stereo sound to one or two pairs of wireless headphones simultaneously. The adapter supports aptX Low Latency, aptX and SBC codecs for synchronised playback. It is designed for travellers, gym users and anyone who wants wireless listening from wired outputs.

Upgrade from single-listener wired connections

This unit replaces the need for a splitter cable or a single-headphone Bluetooth dongle. The jump is worth it when you want two people to hear the same in-flight movie, gym broadcast or TV programme without cables. Battery life reaches 25 hours per charge, and the device operates while connected to USB-C power. First pairing can take up to 90 seconds; subsequent connections are automatic.

Check your source jack and headphone codecs

Verify that the source equipment provides a standard 3.5mm stereo output; some airline seats use a dual-mono connector that requires a separate airline adapter not included here. Confirm your headphones support at least SBC; aptX Low Latency reduces lip-sync delay but is optional. The package includes a USB-C charging cable, travel pouch, keychain holder and quick-start guide. Dimensions are 14.33in W x 12.83in H x 9.06in D and weight is 0.04 pounds.
