3.5mm headset splitter for combined ports

This adapter converts a single 3.5mm combo audio jack into separate headphone and microphone sockets. It enables older headsets with dual plugs to work on newer laptops, tablets and smartphones that only provide one combined port. The 20cm cable keeps the connection tidy for mobile use.

Upgrade from single-plug headsets

The splitter is worth it when a headset uses independent 3.5mm plugs for audio and mic but the device offers only a four-pole jack. It also solves the issue where some condenser microphones fail to become the default input on Apple devices. Users with headsets that already terminate in a single four-pole plug gain no benefit.

Limited by the host device's four-pole

The adapter passes analogue signals only; it cannot add features the host does not support. If a device routes the microphone contact differently or lacks bias voltage for an electret capsule, the external mic will not work. The 20cm length restricts placement to close-range setups such as a laptop bag or desk.
