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.
