Headset Adapter Cable Manhattan 356121

The Manhattan Headset Adapter Cable (model 356121) converts a single 3.5 mm TRRS headset jack into separate 3.5 mm TRS microphone and headphone plugs, allowing headsets with one combined plug to connect to PCs or notebooks with distinct microphone and audio input ports. The slim 15 cm cable is finished in black and silver and is intended for use with common calling and voice-chat applications such as Skype, Teams, Zoom and online gaming voice chat.

Advantages

This adapter uses gold-plated contacts and oxygen-free copper (OFC) conductors to preserve signal integrity and deliver clear audio. The cable features aluminum connector boots for added physical durability and a nylon-braided jacket with strain relief to maintain flexibility and resist wear from repeated plugging and movement. The compact length and slim profile make it convenient for laptop and desktop setups.

Suitable for

• Connecting a single-plug headset to a PC or notebook with separate mic and headphone ports
• Voice and video calls (Skype, Teams, Zoom)
• Online gaming voice chat
• Use with headsets for recording or communication where separate mic and audio jacks are required

How to use

Plug the headset's single 3.5 mm TRRS plug into the adapter's 3.5 mm female socket. Insert the adapter's two 3.5 mm male plugs into the computer's separate audio (headphones) and microphone jacks—typically colour-coded or labeled on the device. Ensure the microphone and headphone are selected in the operating system's audio settings if necessary. The short cable length minimises clutter and is intended for close connections to laptops or desktops.

Recommendations

For best audio quality and reliable connection, avoid excessive bending near the connector ends and unplug by holding the connector housing rather than pulling the cable. Confirm CTIA wiring compatibility with your headset if you encounter microphone detection issues.
