Hetai Tech 3.5 mm Y-Splitter 2 Female to 1 Male Red Green 135 mm

3.5 mm Y-Splitter for Headset and Microphone

This 3.5 mm stereo audio Y-splitter converts a single four-pole 3.5 mm jack into separate headphone and microphone sockets coloured red and green. It is built for users who need to connect a standalone headset and an external microphone to a combined audio port on a laptop, tablet or smartphone. The 135 mm cable weighs 10 g and is intended for mobile recording and karaoke setups.

Replaces a Combined Headset Jack

The adapter upgrades devices that only provide a single 3.5 mm TRRS socket by splitting it into distinct TRS connections for audio output and microphone input. The jump is worth it when a headset with separate plugs must be used on a modern 2-in-1 computer or phone that lacks dedicated ports. It does not add amplification or digital conversion, so signal levels remain identical to the source device.

Limited to Analog Pass-Through

The splitter passes analog stereo and microphone signals without active circuitry, so audio quality depends entirely on the connected headphones and microphone. Real-time monitoring is only supported on iOS 7, 8 and above and Android devices; other phones may only record without live feedback. The cable must be inserted in the correct order — headset and microphone first, then the splitter into the device — or the connection will not function.
