This DELOCK jack cable is used as a headset adapter to connect a headset with separate audio and microphone jacks to devices that use a combined 3.5 mm 4-pole jack connection. The adapter allows headsets with two separate 3.5 mm jack connections to be used on devices such as Apple iPhone, Apple iPad, Apple iPod, Samsung Galaxy, Huawei, Xiaomi, OnePlus, Sony Xperia, Google Pixel, and laptops from brands including Lenovo, Dell, HP, and ASUS. Additionally, the adapter can also be used with game controllers and consoles such as Sony PlayStation 4, Xbox One, and Nintendo Switch with a combined headset port. The adapter features one 3.5 mm male jack connector (4-pole) and two 3.5 mm female jack connectors (3-pole). This separates the audio and microphone signals so that a headset can function correctly on a device with a combined audio and microphone connection. The connectors are equipped with gold-plated contacts that ensure a stable electrical connection and protection against oxidation.
