This slim-profile adapter extends a 3.5mm male TRRS connection to a 3.5mm female TRRS port, using a straight-through pin design that keeps the original 4-conductor signal intact. The narrow male end is built to reach into recessed 3.5mm headphone jacks, making it useful for smartphones in thicker protective cases or for cables with bulky housings.
It is commonly used to connect card swipers and readers that require a full 4-conductor connection, and it fits most (though not guaranteed all) thick phone cases. Gold-plated contacts help maintain a stable, low-resistance connection.
