InLine audio adaptérový kábel 4-polohový 2,5 mm konektor samec / 4-polohový 3,5 mm konektor samica 1 m

The InLine Audio Adapter Cable is a 1 m black adapter lead with a 4‑pin 2.5 mm male connector on one end and a 4‑pin 3.5 mm female socket on the other. It provides a simple way to connect devices that use different mini-jack sizes while preserving stereo and microphone contacts thanks to its four‑pole configuration and gold‑plated contacts for reliable signal transfer.

Advantages

This adapter cable supports 4‑pole connections (TRRS), allowing transmission of left, right and microphone signals between devices with 2.5 mm and 3.5 mm connectors. The gold‑plated contacts improve conductivity and reduce corrosion, and the 1 m cable length gives moderate reach for mobile phones, headsets or camcorders without excess cable slack.

Suitable for

• Connecting headsets or microphones with a 2.5 mm 4‑pin plug to devices with a 3.5 mm 4‑pin jack
• Using mobile phones with non‑standard audio jack sizes
• Connecting digital camcorders or portable recorders to external headsets

Key specifications

• Cable length: 1 m
• Connector 1: 4‑pin 2.5 mm male (plug)
• Connector 2: 4‑pin 3.5 mm female (socket)
• Contacts: gold‑plated
• Colour: black

How to use

Insert the 2.5 mm male plug into the source device that uses a 2.5 mm 4‑pole jack. Connect your headset, microphone or cable with a 3.5 mm 4‑pole plug into the female 3.5 mm socket. Ensure connectors are fully seated to maintain proper contact for audio and microphone functions. No additional software or power is required.

Recommendations

For reliable operation, avoid bending the cable sharply at the connector ends and disconnect by pulling the plug rather than the cable. Check device compatibility for TRRS pin assignments, as some devices use different wiring standards for microphone and remote control functions.
