Cable gender changer Gembird A-3.5F-2.5M

The Gembird A-3.5F-2.5M cable gender changer provides a simple, reliable way to connect audio devices with mismatched connector sizes. It pairs a 3.5 mm female connector with a 2.5 mm male connector and uses gold-plated contacts to maintain signal integrity. The adapter’s compact black housing is designed for easy portability and straightforward inline use with headphones, portable audio players, hands-free kits and other consumer audio equipment.

Advantages

This cable gender changer offers a compact form factor that minimizes bulk while bridging 3.5 mm and 2.5 mm audio connections. Gold-plated contacts reduce corrosion and help preserve audio quality over repeated connections. The simple, single-piece construction requires no tools or power and is compatible with a wide range of devices that use standard 3.5 mm and 2.5 mm connectors. Its black finish is discreet and resists visible wear during normal use.

Suitable for

• Connecting headphones with a 3.5 mm plug to a device with a 2.5 mm socket
• Adapting audio cables between portable players and hands-free car kits
• Temporarily converting connector types for troubleshooting or demonstrations

Key specifications

• Connector A: 3.5 mm female
• Connector B: 2.5 mm male
• Contacts: gold-plated
• Color: black
• Type: passive gender adapter (no electronics)

How to use

Insert the 2.5 mm male connector into the device’s 2.5 mm socket, then plug the 3.5 mm headphone or cable into the 3.5 mm female end. Ensure connectors are fully seated to avoid intermittent audio. No software or configuration is required. When removing, pull the adapter from the connector straight out to avoid stress on cables.

Usage recommendations

Use the adapter for short-term or portable connections rather than permanent installations. Avoid exposing the adapter to moisture or excessive force on the connectors. For the best signal retention, clean contacts periodically and store the adapter in a dry place when not in use.
