🎙️ 3.5mm • 3.5mm TRRS Cable

This cable transmits stereo audio, microphone input, and inline controls between TRRS-compatible devices. It’s used for direct connections, extensions, and modular setups where mic-enabled communication is required.

🧠 Signal Format
TRRS (Tip-Ring-Ring-Sleeve):
Tip = Left audio
Ring 1 = Right audio
Ring 2 = Microphone or control
Sleeve = Ground
Pinout Standards:
CTIA (modern smartphones/tablets)
OMTP (older phones/radios)
Note: Cable does not convert pinout—must match device
 
⚠️ Things to Watch Out For
🔄 TRRS ≠ TRS — cable only works with 4-conductor plugs
🧬 Pinout mismatch — CTIA vs OMTP can affect mic/control
📏 Physical fit — some jacks are recessed or tight
🔊 No signal conversion — purely mechanical cable
🎛️ Mic polarity — may cause hum or silence if mismatched
 
🛠️ Quick Tips for Beginners
🔍 Count the black bands: 3 = TRRS
🧠 Use CTIA-compatible cables for most modern devices
⚡ Don’t force plugs—check fit and orientation
🧰 Keep both varieties for flexible setups
🎛️ Test mic and audio separately—some cables only pass stereo
