2-Pack 3.5mm 4 Pole TRRS Male to 4 Screw Terminal Female Audio Balun Adapter, Solderless Headphone Audio Video Replacement Converter Connector

This package includes 2 pieces of solderless 3.5mm TRRS audio balun converters, equipped with a 4-pole male 3.5mm plug and 4 screw terminal female ports. It supports simultaneous transmission of stereo audio, microphone and analog video signals, ideal for DIY enthusiasts to replace broken headphone cables and customize audio wiring without soldering tools.

Users can directly fix bare audio wires onto the four screw terminals by tightening screws, which greatly simplifies cable repair and audio equipment modification work. Gold-plated internal contacts and full shielding wiring effectively block electromagnetic noise to output crisp, undistorted sound and smooth video signals. The solid plastic housing with reinforced strain relief prevents wire loosening and cracking after long-term use.

No welding equipment or complicated operations needed, plug and play after wiring. Widely applicable for repairing TRRS headsets, custom audio extension cords, surveillance audio-video wiring and portable audio device modification. Perfect for audio hobbyists, electronic maintenance and daily DIY audio upgrade projects.
