4-Position Headset Splitter Cable

The StarTech MUYHSFMM adapter cable connects a single 4-position 3.5 mm headset to a computer that provides separate 3-position microphone and audio jacks. It is built for users who need to plug a combined headset into legacy desktop or laptop ports. The compact PVC-jacketed cable uses nickel-plated connectors and 30 AWG conductors.

Splitter Limited to Analog Stereo and Mono Mic

This passive adapter only carries analog stereo output and a mono microphone signal; it does not convert digital audio, support surround sound, or provide inline volume control. The 4-position female jack accepts CTIA-wired headsets, while the two 3-position male plugs must match the host's distinct mic-in and line-out sockets. No power or driver installation is required.

30 AWG Wire Gauge Determines Cable Flexibility

The 30 AWG conductor size makes the cable thin and highly portable for laptop-bag carry, but it also limits mechanical durability under repeated bending or heavy strain relief. Buyers who need a more rugged permanent installation should consider a thicker-gauge alternative. The nickel-plated contacts resist corrosion in typical office environments.

Questions about this item

Which version of this splitter should I choose for a headset with a single 4-pole plug?

This single model (MUYHSFMM) takes one 4-position 3.5 mm female connector and splits it into two 3-position 3.5 mm male plugs for separate mic and audio ports.

What does the 4-position to 2x 3-position wiring actually do when I plug it into my laptop?

It routes the headset's combined audio and microphone signals into the laptop's separate headphone output and microphone input so VOIP apps recognise both channels.

Does the 3.5 mm interface limit the cable length or audio quality in practice?

The 30 AWG conductors and nickel-plated mini-jacks are built for short desktop runs; longer extensions can add resistance and slight signal loss.
