Bordsek 3.5mm Audio Splitter Blue 27cm

What the product is and who it is for

The Bordsek 3.5 mm audio splitter is a blue, braided Y-cable that converts one 4-pole TRRS female jack into two 3-pole TRS male plugs. It lets users connect a headset with separate microphone and headphone connectors to a PC or laptop that has distinct audio and mic ports. The 27 cm cable is covered in nylon braid and uses 24 K gold-plated contacts inside an aluminium alloy housing.

Who this suits and who should look elsewhere

This adapter suits gamers and office workers whose headsets use the CTIA wiring standard and whose computers provide separate 3.5 mm jacks for audio output and microphone input. It will not work with Apple original earphones or Beats headphones because those use a different pinout. Buyers whose devices only offer a single combined TRRS port or who need a splitter for OMTP-wired headsets should choose a different solution.

The specification that decides fit

The critical specification is the CTIA-standard 4-pole TRRS female input paired with two 3-pole TRS male outputs for discrete audio and microphone channels. Only headsets wired to the CTIA standard will pass both stereo sound and microphone signals through this splitter.
