Share audio and voice with confidence

The MillSO Headset Splitter is a compact 3-foot, 4-pole TRRS adapter that transforms one combined headset jack into two independent TRRS jacks with microphone and audio support. It’s designed for laptops, smartphones, and game consoles, letting two people listen and chat from a single device without a fuss. The setup emphasizes practical comfort and reliable connectivity, opening possibilities for collaborative sessions, casual gaming, or shared media moments.

What it does well

• Splits one 4-pole TRRS port into two full-function TRRS outputs, enabling two headsets or mics to connect to one device.
• Supports simultaneous audio output and microphone input on each end, provided both plugs are 4-pole TRRS; not compatible with IOS standard headphones.
• Extra-long 3-foot cable provides room to move, type, or lean back while staying connected.
• Premium metal housing and 24K gold-plated connectors help resist corrosion and preserve signal quality.

Real-life scenarios

• Co-op gaming sessions where teammates share a single PC or console without swapping cables.
• Group video calls or media sharing on a laptop or smartphone, so two participants can listen and speak clearly.
• Watching movies or listening to music with a friend on a single device, preserving individual volume control through separate jacks.
• Quick classroom or on-the-go collaboration where two headsets or mics are needed for discussion or transcription.

Build, durability, and support

• Sturdy metal enclosure combines a slim form factor with lasting rigidity for daily use.
• Gold-plated connectors help ensure a stable connection and reduced signal loss across devices.
• MillSO offers 24/7 customer service and technical support if compatibility questions arise.

Whether you’re pairing two sets of headphones for shared media or enabling two mics for a quick interview, this splitter provides a practical, non-intrusive solution. It’s a tasteful accessory for teams, families, or friends who want to maximize one device’s audio capabilities without investing in new gear.
