Black 3.5mm TRS Mobile jack Code: 32905354

A 3.5mm (1/8-inch) stereo plug is the standard analog audio connector used for headphones, microphones, and auxiliary cables. It transmits audio using a conductive barrel that is physically divided by insulating rings.

The capabilities of the plug vary depending on the number of contact points (called poles):

• TS (Tip-Sleeve):2 conductors. Used for mono (single-channel) audio or unbalanced instrument cables.
• TRS (Tip-Ring-Sleeve):3 conductors. The standard for stereo audio, transmitting a left channel, a right channel, and a common ground.
• TRRS (Tip-Ring-Ring-Sleeve):4 conductors. Supports stereo audio plus an additional ring used for a microphone signal or video

Connector adapters are commonly used to convert these plugs to other sizes (such as converting a 3.5mm to a larger 6.35mm studio jack) or to join/extend two male aux cables together using a female-to-female coupler. To maximize signal clarity and prevent corrosion, look for adapters featuring gold-plated conductors.
