TwelveSouth announces a Pro version of the AirFly wireless headphone adapter-- a means customers to use wireless headphones or earbuds in places with only a headphone jack featuring audio in capability as well as out.
Audio in functionality allows users to connect a wireless device with an audio system featuring auxiliary audio in, such as a car stereo or legacy hifi equipment, but no Bluetooth streaming connection. Audio out capability remains as standard, of course, allowing one to pair wireless headphones or earbuds with gym treadmills, in-flight entertainment systems and the like.
