Analog audio adapters allow for a simple and straightforward connection between audio source and output devices with different connectors. The Lindy audio adapter from 2.5 mm to 3.5 mm provides a compact solution for connecting devices with 3.5 mm audio plugs, such as headphones or speakers, to source devices with 2.5 mm audio jacks, like many mobile phones. The small, flexible adapter enables an easy connection between both types of devices. The 2.5 mm TRS connector allows for symmetrical mono or asymmetrical stereo signal transmission to a headphone or alternatively for connecting a microphone.
