3.5mm Male to Female CTIA/OMTP Adapter, 4 Conductor TRRS

This 3.5mm adapter converts between the CTIA and OMTP wiring standards, allowing a device wired to one standard to work with headsets, microphones, or accessories wired to the other. It is not a standard straight-through extension cable – it is built specifically for cross-standard conversion, so check your device’s wiring standard before ordering if you’re unsure which one you need.

The 4 conductor (TRRS) male-to-female design supports audio plus microphone signal, making it useful for smartphones and other devices that rely on a 4-conductor connection. It has also been tested with card readers used by payment processing apps that require a 4-conductor jack, and works well with devices that have a thicker port housing thanks to its slim outer profile.
