Cautions
1. Check the number of rings on your plug
This adapter is stereo. If your 3.5mm plug has three rings (e.g., a headset with microphone), it may not work properly. Please verify your plug type before purchase.
2. Direction is fixed
This is a 2.5mm male → 3.5mm female adapter. It cannot be used in reverse (3.5mm male to 2.5mm female).
3. Audio signals only
Do not use for power transmission or high‑frequency digital signals, as this may damage your device or cause signal loss.
4. Align carefully when inserting
The 2.5mm plug is very thin. Insert it straight into the port to avoid bending the internal pin.
