3.5mm TRRS Female to 2.5mm TRRS Male 4-Conductor Adapter

This adapter lets you connect a device with a 2.5mm 4-conductor (TRRS) jack to a cable or accessory that uses a standard 3.5mm 4-conductor (TRRS) connector. It’s a simple pass-through solution for headsets, microphones, or audio cables that don’t match your device’s port size.

The adapter uses a straight-through wiring layout, meaning each conductor connects directly to its matching position (tip to tip, ring to ring, sleeve to sleeve) with no signal rerouting. This keeps audio, microphone, and inline control signals intact between the two connector sizes.

• 3.5mm TRRS 4-conductor female connector
• 2.5mm TRRS 4-conductor male connector
• Straight-through internal wiring (1-1, 2-2, 3-3, 4-4)
• Nickel-plated connectors for durable, corrosion-resistant contacts

Suitable for headsets, earphones, and other audio accessories that need to bridge between 2.5mm and 3.5mm TRRS connections.
