The Twelve South AirFly Pro is ideal for travelling and exercising, as it allows you to use your wireless headphones and earbuds when there's no headphone jack. You now have the ability to pair two sets of earbuds or headphones at the same time. As well as being a transmitter, the AirFly Pro also functions as a Bluetooth receiver, allowing you to stream audio from any Bluetooth device to your car, stereo and more.
