3.5 stereo jack with lock nut
Basic Info
Model No.: CPC 333
Product Description
3.5 mm sockets TRRS (stereo-plus-mic) became particularly common on smartphones, and have been used e.g. by Nokia since 2006; they are often compatible with standard 3.5 mm stereo headphones. Two different forms are frequently found, both of which place left audio on the tip and right audio on the first ring (mirroring the configuration found on stereo connectors). Where they differ is in the placement of the microphone and return contacts. The first, which places the ground return on the second ring and the microphone on the sleeve, is used by Apple's iPhone line, HTC devices, recent Samsung, Nokia, and Sony phones, among others. The second, which reverses these contacts, is used by older Nokia mobiles, older Samsung smartphones, and some Sony Ericsson phones. Some adapters switch the last two conductors to allow a device made to one standard to be used with a headset made to the other.
Some computers now include a TRRS headset socket, compatible with headsets intended for smartphones. One such pin assignment, with ground on the sleeve, is standardized in OMTP and has been accepted as a national Chinese standard YDT 1885-2009.
