FAQ

Will this work with my microphone?
This adapter is primarily designed for Stereo Audio (listening). If your headset has a microphone, the mic function may not work unless the adapter is specifically rated as TRRS (4-pole). This model works best for music and audio output.

Which side goes into the phone?
The thicker pin (3.5mm Male) goes into your phone, laptop, or MP3 player. You plug your smaller headphone jack (2.5mm) into the hole on the back of this adapter.

Is 2.5mm the same as a standard headphone jack?
No. Standard headphones are 3.5mm. 2.5mm is smaller and thinner. This adapter is for when your headphone plug is too small for the hole in your computer.
