InLine Audio Headset Adapter Cable 3.5mm male 4 Pin / 2x 3.5mm, black, 0.15m

The InLine 99302I audio headset adapter cable converts a single 3.5 mm 4‑pin male connection into two separate 3.5 mm female sockets, allowing conventional computer headsets with separate microphone and headphone plugs to be used with devices that provide a combined 4‑pole audio jack. The cable is 0.15 m long, features gold‑plated contacts and a black finish.

Advantages

This adapter supports devices using the CTIA/AHJ 4‑pole pinout common to many smartphones, tablets and laptops, enabling compatibility with headsets that have separate microphone and audio plugs. The gold‑plated contacts improve signal transfer and resist corrosion, while the compact 0.15 m cable reduces clutter and is convenient for mobile use.

Suitable for

• Smartphones and mobile phones with a combined 4‑pole 3.5 mm jack (e.g., many iPhone, HTC models)
• Laptops and notebooks with a single 4‑pole audio output (e.g., some MacBook and certain Lenovo/Dell models)
• Using standard computer headsets with separate headphone and microphone plugs on devices with a combined audio jack

How to use

Confirm audio input and output settings on the device if needed to enable the external headset microphone and speakers.

Recommendations

Use this adapter with headsets that have separate 3.5 mm microphone and headphone plugs. If a device does not detect the external microphone, check the device's pinout compatibility (CTIA/AHJ vs OMTP) and, if necessary, use an alternative adapter that matches the device's wiring standard.
