Audio-adapterkabel 4-pin 2,5mm stekker / 4-pin 3,5mm bus 2m InLine 99308E

The InLine Audio Adapter Cable (model 99308E) converts a 4-pin 2.5mm male connection to a 4-pin 3.5mm female connection. It is a 2.0 m black cable with gold-plated contacts designed to provide reliable signal transfer between compatible mobile phones, digital camcorders and other audio devices requiring 4-pin connections.

Advantages

This adapter cable offers a longer 2 m length for flexible placement and routing, gold-plated contacts to improve conductivity and reduce corrosion, and a standardized 4-pin connection format for compatibility with devices that use 2.5mm and 3.5mm 4-pin audio jacks. The black jacket provides a neutral, unobtrusive appearance and basic mechanical protection for the cable.

Suitable for

• Connecting mobile phones with a 2.5mm 4-pin audio jack to headsets or accessories with a 3.5mm 4-pin socket
• Linking digital camcorders or recorders to external microphones or headsets with differing 2.5mm/3.5mm connector sizes
• Adapting between devices during field recording, interviews or multimedia setups

How to use

Insert the 2.5mm 4-pin male plug into the 2.5mm 4-pin socket on your source device (for example a mobile phone or camcorder). Connect the 3.5mm 4-pin female end to the corresponding 3.5mm 4-pin plug of your headset, microphone or accessory. Ensure connectors are fully seated to establish proper contact and verify audio functionality. Disconnect by gently pulling the connectors straight out without twisting to avoid stress on the cable or jacks.

Recommendations

Use the adapter in dry indoor or sheltered outdoor conditions; avoid exposing the cable to excessive bending, moisture or strain. Verify device pinouts and compatibility before use, since 4-pin wiring can vary between manufacturers—if audio or microphone functions do not work as expected, consult device documentation or test with a known-compatible headset.
