Headset Y-Adapter ShiverPeaks 14-05041 3.5 mm CTIA splitter for headphone and microphone

The Headset Y-Adapter ShiverPeaks 14-05041 3.5 mm CTIA splitter for headphone and microphone is a compact passive adapter that separates a combined TRRS headset signal into two dedicated 3.5 mm jacks: one for headphones (audio out) and one for a microphone (mic in). It is intended for situations where a device provides a single headset connector but you need separate audio and microphone connections for headsets, standalone microphones or older audio equipment. The adapter uses CTIA pinout and a TRRS plug to match common modern headsets and most laptops, desktops and gaming consoles.

Advantages

This passive 3.5 mm CTIA splitter requires no drivers and works plug-and-play, offering a simple physical solution to separate audio and mic channels. Its compact form factor and lightweight construction make it easy to carry and store alongside a laptop or gaming kit. The adapter provides compatibility between combined-jack headsets and devices with separate mic and headphone ports, reducing the need for new cables or adapters.

Suitable for

• Connecting TRRS headsets to desktop PCs with separate microphone and headphone jacks
• Using a combined headset with older laptops or devices that have distinct mic and audio ports
• Gaming consoles and USB hubs that expose separate analog audio and mic inputs
• Audio tests or recording when a headset’s microphone must be routed to a dedicated mic input

Key specifications

• Connector type (input): 3.5 mm TRRS plug, CTIA wiring
• Connector type (outputs): two 3.5 mm TRS jacks — one for headphones (audio out), one for microphone (mic in)
• Compatibility: designed for CTIA-standard headsets and devices with separate mic/headphone ports
• Operation: passive split, no power or drivers required
• Form factor: compact, lightweight inline adapter

How to use

Insert the TRRS plug of the adapter into the combined headset jack on your smartphone, laptop or other device. Then plug the headset’s headphone connector into the audio-out jack and the headset microphone connector into the mic-in jack. The adapter separates the left/right audio channels and the microphone signal to the respective ports, allowing the device to receive audio and mic input independently.

Usage recommendations

Use the adapter in environments where passive splitting is sufficient — it does not provide impedance matching, amplification or signal routing beyond physical separation. For issues with microphone detection or low mic level, verify CTIA wiring compatibility or use a dedicated audio interface or powered adapter designed for impedance and level matching.
