A TRRS connector is a type of audio jack that features four conductors, allowing it to transmit both audio and microphone signals. The acronym stands for Tip, Ring 1, Ring 2, and Sleeve, which refer to the different parts of the connector. This design is commonly used in devices like smartphones, tablets, and laptops, enabling users to connect headphones with built-in microphones for calls or voice commands. The TRRS connector is typically 3.5mm in diameter, similar to the more common TRS connector, which has only three conductors and is used for stereo audio output. The additional conductor in the TRRS connector allows for the integration of a microphone, making it versatile for various applications, including gaming headsets and portable audio devices.
