MillSO 1T2-20 Headset Splitter Adapter

This adapter connects a single 3.5mm 4-pole TRRS headset to a computer that has separate 3-pole TRS microphone and headphone ports. It is built for gamers, remote workers or students who use a CTIA-standard headset with a combined audio and mic plug on a desktop or older laptop that requires two distinct jacks.

Gold-Plated Connectors and Nylon Braided Cable

Connector A is a 3.5mm TRRS female jack plated with 24K gold for low-resistance signal transfer. The two male TRS plugs are colour-coded green for headphones and pink for microphone, and the 20 cm cable uses a nylon braided jacket with strain-relief moulding to resist bending fatigue during daily carry or frequent replugging.

Passive Operation with No External Power

The splitter draws no power and adds no active circuitry, so it introduces no audible noise or thermal load. At 10 grams and measuring 4.02 in by 1.97 in by 0.39 in, it sits unobtrusively behind a PC or in a laptop bag while maintaining full stereo audio and microphone fidelity for VOIP apps such as Skype or Google Voice.

Questions about this item

Does the 3.5 mm TRRS female jack follow the CTIA standard?

Yes, the splitter is designed for CTIA-standard 4-pole headsets and will not work with iOS, Bose or Beats headsets that use a different wiring scheme.

What are the exact dimensions of the adapter body?

The housing measures 4.02 in long, 1.97 in wide and 0.39 in thick, with a 20 cm cable and a weight of 10 grams.

How do I plug the two TRS males into my PC correctly?

Insert the green plug into the headphone port and the pink plug into the microphone port; if the front-panel jacks do not detect the headset, use the rear motherboard jacks instead.
