2.5mm 4-Pole (TRRS) Male to 3.5mm Female Headset Adapter Cable 0.2m

This 2.5mm 4-pole (TRRS) male to 3.5mm female headset adapter cable converts a standard 3.5mm headset/earphone plug to a 2.5mm 4-pole socket. It lets you use stereo headsets with microphones on devices that provide a smaller 2.5mm TRRS port.

Features

• TRRS 4-pole (tip-ring-ring-sleeve) connection for stereo audio plus microphone support

• 2.5mm male to 3.5mm female adapter cable, 0.2 m length for compact, portable use

• Gold-plated contacts to reduce corrosion and improve signal transfer

• Moulded strain relief and flexible cable for durability and frequent use

• Plug-and-play, no drivers or power required

Compatibility and notes

• Use this adapter to connect 3.5mm stereo headsets (with or without mic) to 2.5mm 4-pole jacks on phones, radios, handsets and legacy audio devices.

• Works with headsets that use TRRS wiring standards; however, some devices use non-standard pinouts. If audio or mic functions do not work, the device may use an alternate wiring standard (CTIA/OMTP differences).

• Not suitable for purely mono 2.5mm ports that support only a single channel.
