Wireless Audio Adapter for 3.5 mm Sources

The Twelve South AirFly Pro 12-2010 connects wireless headphones to any device with a 3.5 mm audio jack. It supports Bluetooth 5.0 with aptX Low Latency, aptX and SBC codecs for stereo sound. A built-in microphone allows hands-free calls. The internal battery delivers over 25 hours of playback and charges via USB-C while in use.

For Travel and Shared Listening

Travellers can pair up to two headphones to in-flight entertainment, gym machines or TVs. The 10 m range lets you move freely within the cabin or room. Buyers who need a permanent desktop DAC or a transmitter without a battery should look at other solutions.

Bluetooth 5.0 with aptX Low Latency

This single specification determines whether audio stays in sync with video. The adapter uses Bluetooth 5.0 and aptX Low Latency to minimise lag. Your headphones must also support the codec for the low-latency benefit to work.

Questions about this item

Which AirFly Pro model works with two pairs of wireless headphones at once?

What does the 25-hour battery claim mean on a long-haul flight?

Over 25 hours of continuous playback covers most intercontinental routes, and the unit can stay powered via USB-C while in use.

How does Bluetooth 5.0 with aptX Low Latency affect audio sync when watching movies?

The aptX Low Latency codec keeps sound tightly aligned with video, reducing lip-sync drift to a barely noticeable level on compatible devices.
