MillSO 1T2-20 3.5mm TRRS Female to Dual TRS Male Audio Adapter 20cm

MillSO 1T2-20 TRRS to Dual TRS Adapter

This 20 cm cable splits a single 3.5 mm 4-pole TRRS headset connection into separate 3-pole TRS plugs for headphone and microphone ports. It follows the CTIA standard and uses gold-plated connectors for reliable signal transfer. The compact design suits desktop PCs, older laptops and tablets with separate audio jacks.

Check your headset and device ports before ordering

Ensure the headset uses a single 4-pole TRRS plug wired to the CTIA layout, as iOS, Bose and Beats headsets are not compatible. Verify the computer or tablet provides distinct 3.5 mm TRS sockets for audio output and microphone input. Front-panel jacks may not detect the adapter, so rear-panel ports are recommended.

Suits gamers and remote workers with CTIA headsets

Ideal for users connecting a CTIA gaming headset to a PC or laptop that separates mic and audio jacks for VoIP apps such as Skype or Google Voice. Not for buyers needing a simple headphone doubler, mobile devices with a single combo jack, or headsets using OMTP or proprietary wiring.
