4-Pin to Dual 3-Pin Audio Splitter

This ESTONE HD84 adapter converts a single 3.5mm 4-position female jack into two 3-position male plugs. It lets a headset with combined audio and microphone connect to separate PC or laptop ports. The blue cable measures 5 in. and carries a 2-pack quantity.

Interface Limits for TRRS to Dual TRS

The 3.5mm 4-pin female input accepts a TRRS headset plug carrying stereo output plus a mono microphone. Each 3-pin male output delivers only one signal path: one for stereo headphones, one for the microphone. The cable cannot combine two independent headsets or carry balanced audio.

Mic Compatibility Exclusion

Apple original earphones and Beats headphones will not pass microphone audio through this splitter. The wiring standard used by those brands differs from the CTIA pinout the adapter expects. Buyers using those headsets need a different wiring scheme.
