Important Notes (Please Read)

• Stereo vs mic: This is a stereo coupler. If you need microphone/remote button support (TRRS), compatibility depends on your cable and device type.
• Audio quality: Using very long cables or low-quality cables can introduce noise; this coupler itself does not boost signal.
• Make sure direction is correct: This coupler is female-to-female, so both cables must have male 3.5mm plugs.
