Product Features
Technical Overview
This adapter employs a straightforward splitter architecture that separates the combined audio/microphone signals from a 4-pin TRRS (Tip-Ring-Ring-Sleeve) connector into distinct 3-pin TRS (Tip-Ring-Sleeve) connections. The 4-pin female input connector follows the CTIA/AHJ standard commonly found on modern smartphones, tablets, and laptops with combined headset jacks, while the dual 3-pin male outputs maintain compatibility with traditional PC sound cards, audio interfaces, and recording equipment.
The 30 AWG cable construction provides sufficient current carrying capacity for both audio output and microphone input signals while maintaining flexibility. Nickel plating on all connectors enhances conductivity and provides oxidation resistance for long-term reliability. The adapter supports standard stereo audio output (left and right channels) through one 3-pin connector while routing the microphone signal through the second 3-pin connector.
This section brings together practical product details such as Cable Type, Cable Characteristic, Cable Length, Color Family, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.

FAQ
What devices is this headset splitter adapter compatible with?
The adapter works with any device featuring a standard 4-pin TRRS (CTIA/AHJ) headset jack, including most modern laptops, tablets, smartphones, and gaming consoles. It connects these devices to systems with separate 3-pin microphone and headphone jacks commonly found on desktop computers, audio interfaces, and recording equipment.
How does the 4-pin to dual 3-pin conversion work?
The adapter separates the combined audio and microphone signals from a 4-pin connector into two distinct 3-pin connections. One 3-pin output carries stereo audio (left and right channels) for headphones, while the second 3-pin output carries the microphone signal. This allows devices with combined jacks to connect to systems requiring separate audio input and output ports.
What is the cable length and why is it designed this way?
The cable measures 5.1 inches (129.54 mm), providing enough length for comfortable connection between devices without creating excess cable clutter. This compact design makes the adapter ideal for portable use in laptop bags or tech kits while maintaining a clean workspace appearance in desktop setups.
Are the connectors durable for frequent use?
Yes, all connectors feature nickel plating which enhances conductivity and provides corrosion resistance for long-term reliability. The connectors are designed to withstand repeated plugging and unplugging, making them suitable for daily use in professional environments like contact centers, offices, and field deployments.
