3.5mm Headphone Splitter Adapter – 4-Pole Male to Dual Female (Mic + Audio) Aux Cable

Overview

3.5mm Headphone Splitter Adapter (4‑Pole Male to Dual Female) is an AUX Y‑cable designed to split a single 3.5mm combo headset jack into two separate ports—one for headphones (audio) and one for a microphone (mic). It’s ideal for laptops/PCs or devices that have a single 3.5mm headset port (TRRS) but you want to use separate plugs for mic and audio.

Key Features

• Combo jack splitter: Converts one 3.5mm 4‑pole (TRRS) male plug into two separate 3.5mm female ports.
• Mic + audio separation: One port is for microphone input and the other is for headphone audio output.
• Perfect for meetings & gaming: Use a separate external mic + headphones for clearer voice and sound.
• Plug & play: No drivers, no power—just connect and use.
• Compact & portable: Easy to carry for office, travel, and daily setup.

How to Use

• Plug the 4‑pole (TRRS) male end into your device’s combo headset port.
• Connect your headphones to the audio (headphone) female port.
• Connect your microphone to the mic female port.

Specifications

Important Notes (Please Read)

• Not for two headphones sharing: This splitter is for mic + headphone separation, not for sharing audio to two headsets.
• TRRS compatibility matters: Your device must have a 3.5mm combo headset (TRRS) port for this to work correctly.
• CTIA vs OMTP: Some older devices use different headset wiring standards—if mic doesn’t work, compatibility may be the reason.
• Connect headset first: For best detection, plug your mic/headphones into the splitter before plugging the splitter into the device.

FAQ

What is a 4‑pole (TRRS) plug?
A 4‑pole 3.5mm plug carries stereo audio plus microphone on a single connector (commonly used on combo headset ports).

Will it work on my PC?
It will work if your PC/laptop has a single 3.5mm combo headset jack. If your computer already has two separate jacks (pink mic + green audio), you usually don’t need this adapter.

Why is my mic not working?
Make sure the mic is connected to the correct port, your device supports a TRRS combo jack, and your headset standard matches your device.
