• Here are the standard color codes usually found inside AUX cables:

    🎨 Common Wire Color Codes for TRRS (4-pole)

    Tip (Left Audio) → White (sometimes Blue/Green)

    Ring 1 (Right Audio) → Red

    Ring 2 (Ground for L+R+Mic) → Black / Copper / Bare wire

    Sleeve (Microphone) → Yellow / Green (varies by cable)

    🎨 For TRS (3-pole, only Audio L+R, no mic)

    Tip (Left Audio) → White

    Ring (Right Audio) → Red

    Sleeve (Ground) → Black / Copper / Bare wire

    ⚠️ Note:

    In cheap/local cables, colors sometimes vary → safest way is to use a multimeter continuity test from jack tip/ring to wire end.

    Some cables don’t follow standard, so always confirm before soldering.
